Question While assessing a one-month-old infant, which of the findings warrants further investigation by the nurse? Select all that apply. o A. Abdominal respirations o B. Irregular breathing rate o C. Inspiratory grunt o D. Increased heart rate with crying o E. Nasal flaring o F. Cyanosis o G. Asymmetric chest movement Correct Answers: C, E, F, & G o Option C. Grunting occurs when an infant attempts to maintain an adequate functional residual capacity in the face of poorly compliant lungs by partial glottic closure. As the infant prolongs the expiratory phase against this partially closed glottis, there is a prolonged and increased residual volume that maintains the airway opening and also an audible expiratory sound. o Option E: Nasal flaring occurs when the nostrils widen while breathing and is a sign of troubled breathing or respiratory distress. o Option F: Cyanosis refers to the bluish discoloration of the skin and indicates a decrease in oxygen attached to the red blood cells in the bloodstream. o Option G: Asymmetric chest movement occurs when the abnormal side of the lungs expands less and lags behind the normal side. This indicates respiratory distress. o Option A: Abdominal respiration is normal among infants and young children. Since their intercostal muscles are not yet fully developed, they use their abdominal muscles much more to pull the diaphragm down for breathing. o Option B: Newborns can have irregular breathing patterns ranging from 30 to 60 breaths per minute with short periods of apnea (15 seconds). o Option D: An increase in heart rate is normal for an infant during activity (including crying). Fluctuations in heart rate follow the changes in the newborn’s behavioral state – crying, movement, or wakefulness corresponds to an increase in heart rate.  2. Question A nurse is to administer meperidine hydrochloride (Demerol) 100 mg, atropine sulfate (Atropisol) 0.4 mg, and promethazine hydrochloride (Phenergan) 50 mg IM to a preoperative client. List the order in which the nurse must carry out the following actions prior to the administration of preoperative medications. View Answers: o Place the call bell within reach o Raise the side rails on the bed o Have the client empty bladder o Instruct the client to remain in bed Correct order is shown above. o Have the client empty the bladder. The first step in the process is to have the client void prior to administering the pre-operative medication. If the o D. Have the patient drink activated charcoal mixed with water Correct Answer: A. Gastric lavage o Option A: Acetaminophen overdose is extremely toxic to the liver causing hepatotoxicity. Early symptoms of hepatic damage include nausea, vomiting, abdominal pain, and diarrhea. If not treated immediately, hepatic necrosis occurs and may lead to death. Removing as much of the drug as possible is the first step in treatment for acetaminophen overdose, this is best done through gastric lavage. Gastric lavage (irrigation) and aspiration consist of flushing the stomach with fluids and then aspirating the fluid back out. This procedure is done in life-threatening cases such as acetaminophen toxicity and only if less than one (1) hour has occurred after ingestion. o Option B: The oral formulation of acetylcysteine is the drug of choice for the treatment of acetaminophen overdose but should be done after GI decontamination with activated charcoal. Liver damage is minimized by giving acetylcysteine (Mucomyst), the antidote for acetaminophen. Acetylcysteine reduces injury by substituting for depleted glutathione in the reaction that converts the toxic metabolite of acetaminophen to its nontoxic form. When given within 8 hours of acetaminophen toxicity, acetylcysteine is effective in preventing severe liver injury. It is administered orally or intravenously. o Option C: Intermittent IV infusion with Dextrose 5% may be considered for late-presenting or chronic ingestion. o Option D: Oral activated charcoal (AC) avidly adsorbs acetaminophen and may be administered if the patient presents within 1 hour after ingesting a potentially toxic dose. Charcoal should not be administered immediately before or with antidotes since it can effectively adsorb it and neutralize the benefits.  6. Question Which complication of cardiac catheterization should the nurse monitor for in the initial 24 hours after the procedure? o A. Angina at rest o B. Thrombus formation o C. Dizziness o D. Falling blood pressure Correct Answer: B. Thrombus formation A thrombus formation may prevent blood from flowing normally through the circulatory system, which may become an embolism, and block the flow of blood towards major organs in the body. o Option A: The reported incidence of myocardial infarction with angina at rest is less than 0.1%, and is mostly influenced by patient-related factors like the extent and severity of underlying cardiovascular- related diseases and technique-related factors. o Options C & D: A falling BP and dizziness occur along with hemorrhage of the insertion site which is associated with the first 12 hours after the procedure.  7. Question A client is admitted to the emergency room with renal calculi and is complaining of moderate to severe flank pain and nausea. The client’s temperature is 100.8 degrees Fahrenheit. The priority nursing goal for this client is: o A. Maintain fluid and electrolyte balance o B. Control nausea o C. Manage pain o D. Prevent urinary tract infection Correct Answer: C. Manage pain Managing pain is always a priority because it ultimately improves the quality of life. The cornerstone of ureteral colic management is analgesia, which can be achieved most expediently with parenteral narcotics or nonsteroidal anti-inflammatory drugs (NSAIDs). o Option A: IV hydration in the setting of acute renal colic is controversial. Whereas some authorities believe that IV fluids hasten the passage of the stone through the urogenital system, others express concern that additional hydrostatic pressure exacerbates the pain of renal colic. o Option B: Because nausea and vomiting frequently accompany acute renal colic, antiemetics often play a role in renal colic therapy. Several antiemetics have a sedating effect that is often helpful. o Option D: Overuse of the more effective antibiotic agents leaves only highly resistant bacteria, but failure to adequately treat a UTI complicated by an obstructing calculus can result in potentially life- threatening urosepsis and pyonephrosis.  8. Question What would the nurse expect to see while assessing the growth of children during their school-age years? o A. Decreasing amounts of body fat and muscle mass o B. Little change in body appearance from year to year o C. Progressive height increase of 4 inches each year o D. Yearly weight gain of about 5.5 pounds per year Correct Answer: D. Yearly weight gain of about 5.5 pounds per year School-age children gain about 5.5 pounds each year and increase about 2 inches in height. Between ages 2 to 10 years, a child will grow at a steady pace. o A. Should be taken in the morning o B. May decrease the client’s energy level o C. Must be stored in a dark container o D. Will decrease the client’s heart rate Correct Answer: A. Should be taken in the morning o Option A: Levothyroxine (Synthroid) has a side effect of insomnia. Taking it in the morning could prevent interfering with the client’s sleeping pattern. o Option B: Some of the side effects of Levothyroxine include hyperactivity and an increase in heart rate. o Option C: Keep this drug in a cool, dark, and dry place. o Option D: A decrease in the heart rate is the desired effect of Levothyroxine.  12. Question A 3-year-old child was brought to the pediatric clinic after the sudden onset of findings that include irritability, thick muffled voice, croaking on inspiration, hot to touch, sit leaning forward, tongue protruding, drooling, and suprasternal retractions. What should the nurse do first? o A. Prepare the child for X-ray of upper airways o B. Examine the child’s throat o C. Collect a sputum specimen o D. Notify the healthcare provider of the child’s status Correct Answer: D. Notify the healthcare provider of the child’s status These findings suggest a medical emergency and may be due to epiglottitis. Any child with an acute onset of an inflammatory response in the mouth and throat should receive immediate care. o Option A: If epiglottitis is seriously considered, no imaging studies are required. In less-clear cases, imaging studies are occasionally helpful in establishing the diagnosis or excluding epiglottitis. o Option B: Examining the child’s throat should not be attempted because it may compromise respiratory effort. o Option C: There are no indications for the collection of sputum specimens.  13. Question In children suspected to have a diagnosis of diabetes, which one of the following complaints would be most likely to prompt parents to take their school-age child for evaluation? o A. Polyphagia o B. Dehydration o C. Bedwetting o D. Weight loss Correct Answer: C. Bedwetting One of the first symptoms of type 1 diabetes in children is bedwetting. Bedwetting in a school-age child is readily detected by the parents. o Option A: Polyphagia or extreme hunger is one of the most common symptoms of diabetes both among adults and children. o Option B: Dehydration is not a symptom of type 1 diabetes, but it can be one of the many complications. o Option D: Unintentional weight loss would develop gradually in a child with type 1 diabetes.  14. Question A client comes to the clinic for treatment of recurrent pelvic inflammatory disease. The nurse recognizes that this condition most frequently follows which type of infection? o A. Trichomoniasis o B. Chlamydia o C. Staphylococcus o D. Streptococcus Correct Answer: B. Chlamydia o Option B: Chlamydial infections are one of the most frequent causes of salpingitis or pelvic inflammatory disease. Chlamydial bacteria could travel up toward the vagina or cervix into the reproductive organs. o Option A: Trichomoniasis is a very common sexually transmitted disease, but it rarely predisposes to pelvic inflammatory disease. o Options C & D: Staphylococcus and streptococcus may cause PID but it rarely occurs.  15. Question A registered nurse who usually works in a spinal rehabilitation unit is floated to the emergency department. Which of these clients should the charge nurse assign to this RN? o A. A middle-aged client who says “I took too many diet pills” and “my heart feels like it is racing out of my chest.” o B. A young adult who says “I hear songs from heaven. I need money for beer. I quit drinking two (2) days ago for my family. Why are my arms and legs jerking?” o C. An adolescent who has been on pain medications terminal cancer with an initial assessment finding pupils and a relaxed respiratory rate of 11, The nurse is speaking at a community meeting about personal responsibility for health promotion. A participant asks about chiropractic treatment for illnesses. What should be the focus of the nurse’s response? o A. Electrical energy fields o B. Spinal column manipulation o C. Mind-body balance o D. Exercise of joints Correct Answer: B. Spinal column manipulation The theory underlying chiropractic is that interference with the transmission of mental impulses between the brain and body organs produces diseases. Such interference is caused by the misalignment of the vertebrae. Manipulation reduces subluxation. o Option A: Too much exposure to electrical energy can become a hazard to one’s health. o Option C: Mind-body balance refers to yoga. o Option D: Low-impact aerobic exercises are easier on the joints but are not part of chiropractic medicine.  19. Question The nurse is performing a neurological assessment on a client post right cerebrovascular accident. Which finding, if observed by the nurse, would warrant immediate attention? o A. Decrease in the level of consciousness o B. Loss of bladder control o C. Altered sensation to stimuli o D. Emotional lability Correct Answer: A. Decrease in the level of consciousness A further decrease in the level of consciousness may indicate an increase in intracranial pressure leading to inadequate oxygenation of the brain. A decrease in LOC may also reveal the presence of a transient ischemic attack which may warn of impending thrombotic CVA. o Option B: The patient post-stroke may have transient urinary incontinence due to inability to communicate needs, or impaired motor and postural control. Control of the urinary sphincter may also be lost or diminished. o Option C: Altered sensation to stimuli is expected for a patient post CVA. This may include sensory impairment to touch, loss of proprioception, difficulty interpreting visual, tactile, and auditory stimuli. o Option D: Depression and anxiety are common responses by a patient after a catastrophic event such as in stroke. Emotional lability (or pseudobulbar affect), refers to the involuntary and uncontrollable bursts of emotion without an emotional trigger.  20. Question A child who has recently been diagnosed with cystic fibrosis is in a pediatric clinic where a nurse is performing an assessment. Which later finding of this disease would the nurse not expect to see at this time? o A. Positive sweat test o B. Bulky greasy stools o C. Moist, productive cough o D. Meconium ileus Correct Answer: C. Moist, productive cough Noisy respirations and a dry non-productive cough are commonly the first of the respiratory signs to appear in a newly diagnosed client with cystic fibrosis (CF). The other options are the earliest findings. CF is an inherited (genetic) condition affecting the cells that produce mucus, sweat, saliva, and digestive juices. Normally, these secretions are thin and slippery, but in CF, a defective gene causes the secretions to become thick and sticky. Instead of acting as a lubricant, the secretions plug up tubes, ducts, and passageways, especially in the pancreas and lungs. Respiratory failure is the most dangerous consequence of CF. o Option A: A positive sweat test is one of the indications of cystic fibrosis. o Option B: A patient with CF experiences frequent greasy, bulky stools or difficulty with bowel movements as the thick mucus blocks the intestines. o Option D: Meconium ileus is one of the early signs of CF.  21. Question The home health nurse visits a male client to provide wound care and finds the client lethargic and confused. His wife states he fell down the stairs two (2) hours ago. The nurse should o A. Place a call to the client’s health care provider for instructions o B. Send him to the emergency room for evaluation o C. Reassure the client’s wife that the symptoms are transient o D. Instruct the client’s wife to call the doctor if his symptoms become worse Correct Answer: B. Send him to the emergency room for evaluation This client requires immediate evaluation. A delay in treatment could result in further deterioration and harm. Home care nurses must prioritize interventions based on assessment findings that are in the client’s best interest. o Option A: Waiting to call for instructions may delay the diagnosis of the patient. o Option C: Reassuring the wife is since it is not a transient symptom. Correct Answer: B. A teenager who got a singed beard while camping This client is in the greatest danger with a potential of respiratory distress. Any client with singed facial hair has been exposed to heat or fire in close range that could have caused serious damage to the interior of the lungs. Note that the interior lining of the lungs has no nerve fibers so the client will not be aware of swelling. o Option A: When an infant is crying, the fontanels may look like they are bulging. o Option C: The client in Option C can wait to be seen within the first hour. o Option D: The client in Option D does not have a life- threatening condition but will still require immediate pain relief.  25. Question While planning care for a toddler, the nurse teaches the parents about the expected developmental changes for this age. Which statement by the mother shows that she understands the child’s developmental needs? o A. “I want to protect my child from any falls.” o B. “I will set limits on exploring the house.” o C. “I understand the need to use those new skills.” o D. “I intend to keep control over our child.” Correct Answer: C. “I understand the need to use those new skills.” Erikson describes the stage of the toddler as being the time when there is normally an increase in autonomy. The child needs to use motor skills to explore the environment and develop autonomy. o Option A: The statement in Option A is correct but pertains to the risks associated with a toddler. o Option B: Setting limits on a toddler may cause frustration instead of independence. o Option D: Controlling the child may be harmful to her development as toddlers should be developing their autonomy at this stage.  26. Question The nurse is preparing to administer an enteral feeding to a client via a nasogastric feeding tube. The most important action of the nurse is: o A. Verify correct placement of the tube o B. Check that the feeding solution matches the dietary order o C. Aspirate abdominal contents to determine the amount of last feeding remaining in stomach o D. Ensure that feeding solution is at room temperature Correct Answer: A. Verify correct placement of the tube Proper placement of the tube prevents aspiration and entrance of food content into the lungs. The definitive way to ascertain the position of the nasogastric tube is through visualization by an x- ray. Another method is to aspirate stomach contents and check its pH (usually pH 1 to 5). Aspirated stomach content can also be tested for bilirubin to confirm it is placed in the stomach. o Option B: It is also important to check that the feeding solution matches the dietary order to ensure that the client gets proper nutrition. o Option C: Aspirating the gastric contents is one of the methods used to determine the last feeding amount in the stomach, but is not the most important action the nurse should do. o Option D: Keep it at room temperature so it would not upset the stomach.  27. Question The nurse is caring for a client with a serum potassium level of 3.5 mEq/L. The client is placed on a cardiac monitor and receives 40 mEq potassium chloride in 1000 ml of 5% dextrose in water IV. Which of the following EKG patterns indicates to the nurse that the infusions should be discontinued? o A. Narrowed QRS complex o B. Shortened “PR” interval o C. Tall peaked "T" waves o D. Prominent “U” waves Correct Answer: C. Tall peaked “T” waves A tall peaked T wave is a sign of hyperkalemia. The healthcare provider should be notified regarding discontinuing the medication. o Option A: Narrow QRS complex indicates fast cardiac rhythms (generally more than 100 beats/min) with a QRS duration of 100 ms or less. o Option B: A short PR interval (<120 ms) is seen with preexcitation syndromes and AV nodal (junctional) rhythm. o Option D: Prominent U waves are characteristic of hypokalemia.  28. Question A nurse prepares to care for a 4-year-old newly admitted for rhabdomyosarcoma. The nurse should alert the staff to pay more attention to the function of which area of the body? o A. All striated muscles o B. The cerebellum o C. The kidneys o D. The leg bones Correct Answer: A. All striated muscles o A. Stroke volume o B. Cardiac output o C. Venous pressure o D. Left ventricular functioning Correct Answer: D. Left ventricular functioning The catheter is placed in the pulmonary artery. Information regarding left ventricular function is obtained when the catheter balloon is inflated. o Option A: Stroke volume is calculated using measurements of ventricle volumes from an echocardiogram and subtracting the volume of the blood in the ventricle at the end of a beat (called end- systolic volume) from the volume of blood just prior to the beat (called end-diastolic volume). o Option B: Cardiac output is calculated by multiplying the stroke volume by the heart rate. o Option C: The CVP can be measured either manually using a manometer or electronically using a transducer.  32. Question A nurse enters a client’s room to discover that the client has no pulse or respirations. After calling for help, the first action the nurse should take is: o A. Start a peripheral IV o B. Initiate high-quality chest compressions o C. Establish an airway o D. Obtain the crash cart Correct Answer: B. Initiate high-quality chest compressions As per new guidelines, the American Heart Association recommends beginning CPR with chest compression (rather than checking for the airway first). Start CPR with 30 chest compressions before checking the airway and giving rescue breaths. Starting with chest compressions first applies to adults, children, and infants needing CPR, but not newborns. CPR can keep oxygenated blood flowing to the brain and other vital organs until more definitive medical treatment can restore a normal heart rhythm. o Option A: Starting a peripheral IV can come after the C-A-B sequence. o Option C: Establishing an airway comes after compressions. o Option D: After performing the guidelines by the AHA, the crash cart can be obtained by another nurse responding to the scene.  33. Question A client is receiving digoxin (Lanoxin) 0.25 mg daily. The health care provider has written a new order to give metoprolol (Lopressor) 25 mg B.I.D. In assessing the client prior to administering the medications, which of the following should the nurse report immediately to the health care provider? o A. Blood pressure 94/60 mm Hg o B. Heart rate 76 bpm o C. Urine output 50 ml/hour o D. Respiratory rate 16 bpm Correct Answer: A. Blood pressure 94/60 mm Hg Both medications decrease the heart rate. Metoprolol affects blood pressure. Therefore, the heart rate and blood pressure must be within the normal range (HR 60-100; systolic BP over 100) in order to safely administer both medications. o Option B: A heart rate of 76 is within the normal range. o Option C: Increase in urine output is the desired effect of diuretics, which is given with digoxin. o Option D: A respiratory rate of 16 is within the normal range.  34. Question The nurse practicing in a maternity setting recognizes that the postmature fetus is at risk due to: o A. Excessive fetal weight o B. Low blood sugar levels o C. Depletion of subcutaneous fat o D. Progressive placental insufficiency Correct Answer: D. Progressive placental insufficiency Postmature or post-term pregnancy is a prolonged pregnancy that exceeds the limits of 38 to 42 weeks (normal term pregnancy). Infants of such pregnancy are considered postmature or dysmature if there is evidence that placental insufficiency has occurred and interfered with fetal growth. It occurs in 12% of all pregnancies. The placenta loses its adequacy to function after 42 weeks, after which it acquires calcium deposits which decrease the blood perfusion, supply of oxygen and nutrients to the fetus. o Options A, B, & C: Excessive fetal weight, hypoglycemia, and depletion of subcutaneous fat are all observed in a postmature fetus.  35. Question The nurse is caring for a client who had a total hip replacement seven (7) days ago. Which statement by the client requires the nurse’s immediate attention? o A. I have bad muscle spasms in my lower leg of the affected extremity. extremities causing the cells to die or necrose. This ultimately leads to the formation of venous stasis ulcers characterized by shallow but large brown wounds with irregular margins that typically develop on the lower leg or ankle. The goal of clinical management in a client with venous stasis ulcers is to promote healing. This only can be accomplished with proper nutrition. Nutritional deficiencies are common causes of venous ulcers. Alterations in the diet to include foods high in protein, iron, zinc, and vitamins C and A are encouraged to promote wound healing. o Option A: Dressings are often used under compression bandages to promote faster healing and prevent adherence of the bandage to the ulcer. A wide range of dressings are available, including hydrocolloids (e.g., Duoderm), foams, hydrogels, pastes, and simple non-adherent dressings. o Option C: Compression therapy is the standard of care for venous ulcers and chronic venous insufficiency. A recent Cochrane review found that venous ulcers heal more quickly with compression therapy than without. Methods include inelastic, elastic, and intermittent pneumatic compression. Compression therapy reduces edema, improves venous reflux, enhances healing of ulcers, and reduces pain. o Option D: Removal of necrotic tissue and bacterial burden through debridement has long been used in wound care to enhance healing. Debridement may be sharp (e.g., using a curette or scissors), enzymatic, mechanical, biologic (i.e., using larvae), or autolytic.  38. Question Which of these statements best describes the characteristics of an effective reward-feedback system? o A. Specific feedback is given as close to the event as possible o B. Staff is given feedback in equal amounts over time o C. Positive statements are to precede a negative statement o D. Performance goals should be higher than what is attainable Correct Answer: A. Specific feedback is given as close to the event as possible Feedback is most useful when given immediately. Positive behavior is strengthened through immediate feedback, and it is easier to modify problem behaviors if the standards are clearly understood. o Option B: Positive feedback is most useful when given immediately. o Option C: Negative statements are never helpful in any given situation. o Option D: Every goal should always be attainable.  39. Question The nurse is providing information to a client with multiple sclerosis on performing exercises and physical activities. The nurse determines the client needs additional teaching if the client makes which statements? Select all that apply. o A. “I can lift weights and do resistance training.” o B. “I should exercise to the point of exhaustion.” o C. “I can include aerobic exercises in my routine.” o D. “Proper stretching should be done before starting my routine.” o E. “I should exercise continuously without rest.” Correct answers: B & E. o Option B: Patients with multiple sclerosis should not exercise to the point of fatigue as strenuous physical exercise raises body temperature and may aggravate symptoms. o Option E: Continuous exercise with no rest periods is contraindicated for patients with multiple sclerosis who wants to exercise. The patient should be advised to take short rest periods, preferably lying down. Again, extreme fatigue may contribute to the exacerbation of symptoms. o Option A: Exercises should include activities that would strengthen weak muscles because diminishing muscle strength is often a primary concern in multiple sclerosis. These activities include lifting weights and resistance exercises. o Option C: Aerobic exercises help promote muscle efficiency, increase flexibility, improves mood, and helps eliminate stress. o Option D: Muscle stretching should be included prior to exercise as this helps minimize muscle spasticity and contractures which is common in later stages of multiple sclerosis.  40. Question During the evaluation of the quality of home care for a client with Alzheimer’s disease, the priority for the nurse is to reinforce which statement by a family member? o A. “At least two (2) full meals a day are eaten.” o B. “We go to a group discussion every week at our community center.” o C. “We have safety bars installed in the bathroom and have 24-hour alarms on the doors.” o D. “The medication is not a problem to have it taken three (3) times a day.” Correct Answer: C. We have safety bars installed in the bathroom and have 24-hour alarms on the doors. Note all options are correct statements. However, safety is most important to reinforce. o Option C: Ensuring safety of the client with increasing memory loss is a priority of home care. In addition to installation of safety bars, all obvious hazards should body interact with UV rays from the sun. Anti-infectives are the most common cause of this type of reaction. o Option A: Ciprofloxacin is used to treat a variety of bacterial infections. Ciprofloxacin belongs to a class of drugs called quinolone antibiotics. It works by stopping the growth of bacteria. This antibiotic treats only bacterial infections. It will not work for virus infections (such as common cold, flu). Unnecessary use or overuse of any antibiotic can lead to its decreased effectiveness. o Option B: Sulfonamides are synthetic bacteriostatic antibiotics that competitively inhibit conversion of p- aminobenzoic acid to dihydropteroate, which bacteria need for folate synthesis and ultimately purine and DNA synthesis. Humans do not synthesize folate but acquire it in their diet, so their DNA synthesis is less affected. o Option C: Norfloxacin is an antibiotic in a group of drugs called fluoroquinolones. Norfloxacin fights bacteria in the body. Norfloxacin is used to treat different bacterial infections of the prostate or urinary tract (bladder and kidneys). Norfloxacin is also used to treat gonorrhea. o Option D: Sulfamethoxazole and trimethoprim combination is used to treat infections such as urinary tract infections, middle ear infections (otitis media), bronchitis, traveler’s diarrhea, and shigellosis (bacillary dysentery). This medicine is also used to prevent or treat Pneumocystis jiroveci pneumonia or Pneumocystis carinii pneumonia (PCP), a very serious kind of pneumonia. Sulfamethoxazole and trimethoprim combination is an antibiotic. It works by eliminating the bacteria that cause many kinds of infections. o Option E: Isotretinoin is a drug used to treat severe acne that hasn’t responded to other treatments. It may be prescribed for other uses, including other skin problems and certain kinds of cancer. This drug is a vitamin A derivative (retinoid), so your body reacts to it in a similar way that it does to vitamin A. o Option F: Nitro-Dur patch is used to prevent chest pain or angina. Its side effects are headache, lightheadedness, nausea, and flushing.  43. Question A patient tells you that her urine is starting to look discolored. If you believe this change is due to medication, which of the following of the patient’s medication does not cause urine discoloration? o A. Sulfasalazine o B. Levodopa o C. Phenolphthalein o D. Aspirin Correct Answer: D. Aspirin Aspirin is not known to cause discoloration of the urine. Side effects and complications of taking aspirin include stroke caused by a burst blood vessel. The Food and Drug Administration doesn’t recommend aspirin therapy for the prevention of heart attacks in people who haven’t already had a heart attack, stroke or another cardiovascular condition. o Option A: Sulfasalazine may discolor the urine or skin to orange-yellow color. Sulfasalazine is used to treat ulcerative colitis (UC), and to decrease the frequency of UC attacks. Sulfasalazine will not cure ulcerative colitis, but it can reduce the number of attacks you have. o Option B: Levodopa may discolor the urine, saliva, or sweat to a dark brown color. Levodopa is in a class of medications called central nervous system agents. It works by being converted to dopamine in the brain. Carbidopa is in a class of medications called decarboxylase inhibitors. It works by preventing levodopa from being broken down before it reaches the brain. o Option C: Phenolphthalein can discolor the urine to a red color. Phenolphthalein is often used as an indicator in acid-base titrations. For this application, it turns colorless in acidic solutions and pink in basic solutions.  44. Question You are responsible for reviewing the nursing unit’s refrigerator. Which of the following drugs, if found inside the fridge, should be removed? o A. Nadolol (Corgard) o B. Opened (in-use) Humulin N injection o C. Urokinase (Kinlytic) o D. Epoetin alfa IV (Epogen) Correct Answer: A. Corgard Nadolol (Corgard) is stored at room temperature between 59 to 86 ºF (15 and 30 ºC) away from heat, moisture, and light. Do not store in the bathroom and keep the bottle tightly closed. o Option B: Humulin N injection if unopened (not in use) is stored in the fridge and can be used until the expiration date, or stored at room temperature and used within 31 days. If opened (in-use), store the vial in a refrigerator or at room temperature and use within 31 days. Store the injection pen at room temperature (do not refrigerate) and use within 14 days. Keep it in its original container protected from heat and light. Do not draw insulin from a vial into a syringe until you are ready to give an injection. Do not freeze insulin or store it near the cooling element in a refrigerator. Throw away any insulin that has been frozen. o Option C: Urokinase (Kinlytic) is refrigerated at 2–8°C. Lyophilized Urokinase although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Urokinase should be stored at 4°C between 2-7 days and for future use below -18°C. worker might feel anger, fear, blame, or depression. During the difficult time of prevention treatment and waiting, they may want to seek support. Try an employee-assistance program or local mental health expert.  47. Question A thirty-five-year-old male has been an insulin-dependent diabetic for five years and now is unable to urinate. Which of the following would you most likely suspect? o A. Atherosclerosis o B. Diabetic nephropathy o C. Autonomic neuropathy o D. Somatic neuropathy Correct Answer: C. Autonomic neuropathy Autonomic neuropathy (also known as Diabetic Autonomic Neuropathy) affects the autonomic nerves, which control the bladder, intestinal tract, and genitals, among other organs. Paralysis of the bladder is a common symptom of this type of neuropathy, as manifested by bladder urgency and inability to start urination. o Option A: Atherosclerosis, or hardening of the arteries, is a condition in which plaque builds up inside the arteries. Plaque is made of cholesterol, fatty substances, cellular waste products, calcium, and fibrin (a clotting material in the blood). o Option B: Diabetic nephropathy (DN) is typically defined by macro albuminuria—that is, a urinary albumin excretion of more than 300 mg in a 24-hour collection—or macroalbuminuria and abnormal renal function as represented by an abnormality in serum creatinine, calculated creatinine clearance, or glomerular filtration rate (GFR). Clinically, diabetic nephropathy is characterized by a progressive increase in proteinuria and an increased need to urinate. o Option D: Somatic neuropathy affects the whole body and presents with diverse clinical pictures, most common is the development of diabetic foot followed by diabetic ulceration and possible amputation.  48. Question You are taking the history of a 14-year-old girl who has a (BMI) of 18. The girl reports inability to eat, induced vomiting and severe constipation. Which of the following would you most likely suspect? o A. Multiple sclerosis o B. Anorexia nervosa o C. Bulimia nervosa o D. Systemic sclerosis Correct Answer: B. Anorexia nervosa All of the clinical signs and symptoms point to a condition of anorexia nervosa. The key feature of anorexia nervosa is self- imposed starvation, resulting from a distorted body image and an intense, irrational fear of gaining weight, even when the patient is emaciated. Anorexia nervosa may include refusal to eat accompanied by compulsive exercising, self-induced vomiting, or laxative or diuretic abuse. o Option A: Multiple sclerosis (MS) is a demyelinating disease in which the insulating covers of the nerve cells in the brain and spinal cord are damaged. o Option C: On the other hand, bulimia nervosa features binge eating followed by a feeling of guilt, humiliation, and self-deprecation. These feelings cause the patient to engage in self-induced vomiting, use of laxatives, or diuretics. o Option D: Systemic sclerosis or systemic scleroderma is an autoimmune disease of the connective tissue.  49. Question A 24-year-old female is admitted to the ER due to confusion. This patient has a history of a myeloma diagnosis, constipation, intense abdominal pain, and polyuria. Based on the presenting signs and symptoms, which of the following would you most likely suspect? o A. Diverticulosis o B. Hypercalcemia o C. Hypocalcemia o D. Irritable bowel syndrome Correct Answer: B. Hypercalcemia Hypercalcemia can cause polyuria, severe abdominal pain, and confusion. o Option A: Diverticulosis is a condition that develops when pouches (diverticula) form in the wall of the large intestine; most people don’t have symptoms. o Option C: Hypocalcemia is low calcium levels in the blood; it is asymptomatic in mild forms but can cause paresthesia, tetany, muscle cramps, and carpopedal spasms in severe hypocalcemia. o Option D: Irritable bowel syndrome is a widespread condition involving recurrent abdominal pain and diarrhea or constipation, often associated with stress, depression, anxiety, or previous intestinal infection.  50. Question Rhogam is most often used to treat____ mothers that have a ____ infant. o A. RH positive, RH positive o B. RH positive, RH negative o C. RH negative, RH positive hair than unaffected family members and are also likely to have skin disorders such as eczema.  52. Question A patient has taken an overdose of aspirin. Which of the following should a nurse must closely monitor for during acute management of this patient? o A. Onset of pulmonary edema o B. Metabolic alkalosis o C. Respiratory alkalosis o D. Parkinson’s disease type symptoms Correct Answer: A. Onset of pulmonary edema Aspirin overdose can lead to metabolic acidosis and cause pulmonary edema development. Early symptoms of aspirin poisoning also include tinnitus, hyperventilation, vomiting, dehydration, and fever. Late signs include drowsiness, bizarre behavior, unsteady walking, and coma. Abnormal breathing caused by aspirin poisoning is usually rapid and deep. Pulmonary edema may be related to an increase in permeability within the capillaries of the lung leading to “protein leakage” and transudation of fluid in both renal and pulmonary tissues. The alteration in renal tubule permeability may lead to a change in colloid osmotic pressure and thus facilitate pulmonary edema (via Medscape). o Option B: Aspirin overdose causes metabolic acidosis, not alkalosis. Metabolic alkalosis is a primary increase in serum bicarbonate (HCO3 -) concentration. o Option C: Respiratory alkalosis is a disturbance in acid and base balance due to alveolar hyperventilation. o Option D: Parkinson’s type symptoms include tremors, bradykinesia, rigid muscles, impaired posture and balance, speech changes, and loss of automatic movements.  53. Question A 50-year-old blind and deaf patient has been admitted to your floor. As the charge nurse, your primary responsibility for this patient is? o A. Let others know about the patient’s deficits. o B. Communicate with your supervisor your patient safety concerns. o C. Continuously update the patient on the social environment. o D. Provide a secure environment for the patient. Correct Answer: D. Provide a secure environment for the patient. This patient’s safety is your primary concern. Patient safety protocols can help reduce medical mistakes and prevent adverse patient outcomes. When the goal is to help people, it seems obvious that it’s important to work to protect them from unintended or unexpected harm. o Option A: Letting others know is correct, so that the other staff may become aware of the patient’s condition. However, this is not a priority. o Option B: Before communication with the supervisor, the charge nurse must secure the environmental safety of the client first. o Option C: Continuously updating the patient on the social environment is also correct, but this can come after securing the client’s safety.  54. Question A patient is getting discharged from a skilled nursing facility (SNF). The patient has a history of severe COPD and PVD. The patient is primarily concerned about his ability to breathe easily. Which of the following would be the best instruction for this patient? o A. Deep breathing techniques to increase oxygen levels. o B. Cough regularly and deeply to clear airway passages. o C. Cough following bronchodilator utilization. o D. Decrease CO2 levels by increased oxygen take output during meals. Correct Answer: C. Cough following bronchodilator utilization The bronchodilator will allow a more productive cough. o Option A: Deep breathing exercises can help the client’s lungs from becoming more damaged. When one has healthy lungs, breathing is natural and easy. You breathe in and out with the diaphragm doing about 80 percent of the work to fill the lungs with a mixture of oxygen and other gases, and then send the waste gas out. o Option B: Coughing may help clear the airway, however, it may not be as effective as taking bronchodilators. Coughing moves mucus out of the large airways. However, moving mucus out of the small airways requires airway clearance techniques (ACTs). This is why coughing should be done with other ACTs. o Option D: Changing the level of oxygen at home without asking the healthcare provider is not recommended.  55. Question A nurse is caring for an infant that has recently been diagnosed with a congenital heart defect. Which of the following clinical signs would most likely be present? o A. Slow pulse rate o B. Weight gain o C. Decreased systolic pressure o D. Irregular WBC lab values o Option B: Although current guidelines do not include renal dysfunction as a contraindication to tPA therapy, some clinicians hesitate to administer tPA because of a tendency of bleeding in these patients. o Option C: Having a food diary is not related to the use of medication. Thrombolytic therapy is indicated in patients with evidence of ST-segment elevation MI (STEMI) or presumably new left bundle-branch block (LBBB) presenting within 12 hours of the onset of symptoms if there are no contraindications to fibrinolysis.  58. Question A patient asks a nurse, “My doctor recommended I increase my intake of folic acid. What type of foods contain the highest concentration of folic acids?” o A. Green vegetables and liver o B. Yellow vegetables and red meat o C. Carrots o D. Milk Correct Answer: A. Green vegetables and liver Green vegetables and liver are a great source of folic acid. o Option B: Yellow vegetables are great sources of vitamins, such as vitamins A, B6, C, folate, magnesium, fiber, riboflavin, phosphorus, and potassium. Red meat is rich in protein, saturated fat, iron, zinc, and vitamin B. o Option C: Carrots are a rich source of vitamin A from beta carotene, K1 (phylloquinone), and vitamin B6. o Option D: Milk is a rich source of calcium. Milk is an excellent source of many vitamins and minerals, including vitamin B12, calcium, riboflavin, and phosphorus. It’s often fortified with other vitamins, especially vitamin D.  59. Question A nurse is putting together a presentation on meningitis. Which of the following microorganisms has not been linked to meningitis in humans? o A. S. pneumoniae o B. H. influenzae o C. N. meningitidis o D. Cl. difficile Correct Answer: D. Cl. difficile Cl. difficile has not been linked to meningitis. Clostridium difficile (C. diff ) is a germ (bacteria) that causes life-threatening diarrhea. It is usually a side-effect of taking antibiotics. o Option A: Pneumococcal meningitis is caused by Streptococcus pneumoniae. The most common route of infection starts by nasopharyngeal colonization by Streptococcus pneumoniae, which must avoid mucosal entrapment and evade the host immune system after local activation. o Option B: H influenzae meningitis is caused by Haemophilus influenzae type B bacteria. It is the leading cause of bacterial meningitis in children under age 5. Haemophilus species are small oxidase-positive pleomorphic gram-negative aerobic or facultative anaerobic coccobacilli. Humans are the only known host for Haemophilus influenza. o Option C: Bacteria called Neisseria meningitidis cause meningococcal disease. About 1 in 10 people have these bacteria in the back of their nose and throat without being ill.  60. Question A nurse is administering blood to a patient who has a low hemoglobin count. The patient asks how long do red blood cells live in my body? The correct response is: o A. The life span of RBC is 45 days o B. The life span of RBC is 60 days o C. The life span of RBC is 90 days o D. The life span of RBC is 120 days Correct Answer: D. The life span of RBC is 120 days Red blood cells have a lifespan of 120 in the body. Today, RBC population studies are performed with a label that is placed on the RBC ex vivo, making it possible to study both donor and autologous RBC. o Option A: Human red blood cells (RBC), after differentiating from erythroblasts in the bone marrow, are released into the blood and survive in the circulation for approximately 115 days. In humans and some other species, RBC normally survives in a nonrandom manner. This means that all of the RBC in an age cohort are removed by the reticuloendothelial system at about the same time. o Option B: Accurate measurement of long-term survival requires determination of the amount of remaining labeled RBC for all or most of the RBC lifespan. Optimal determination of long-term survival also requires a steady-state situation, with the important variable depending on the label used. o Option C: Only recently with the introduction of the biotin label has a method become available that allows the detection, analysis, and isolation of aging RBC and thus detailed studies of their properties.  61. Question A 65-year-old man has been admitted to the hospital for spinal stenosis surgery. When should the discharge training and planning begin for this patient? o A. Following surgery o B. Upon admission o C. Within 48 hours of discharge continues to approximately 18 months of age. During this stage, children learn whether or not they can trust the people around them. o Option B: It is as children enter the preschool years (3-6 years old) that they begin the third stage of psychosocial development centered on initiative versus guilt. It is important for the kids to learn that they can exert power over themselves and the world. o Option D: Intimacy vs Isolation takes place during young adulthood between the ages of approximately 19 and 40. The major conflict at this stage of life centers on forming intimate, loving relationships with other people.  64. Question A young adult is 20 years old and has been recently admitted to the hospital. According to Erikson, which of the following stages is the adult in? o A. Trust vs. mistrust o B. Initiative vs. guilt o C. Autonomy vs. shame o D. Intimacy vs. isolation Correct Answer: D. Intimacy vs. isolation Intimacy vs Isolation takes place during young adulthood between the ages of approximately 19 and 40. The major conflict at this stage of life centers on forming intimate, loving relationships with other people. o Option A: Trust vs Mistrust is the first stage of the psychosocial theory. This stage begins at birth and continues to approximately 18 months of age. During this stage, children learn whether or not they can trust the people around them. o Option B: It is as children enter the preschool years (3-6 years old) that they begin the third stage of psychosocial development centered on initiative versus guilt. It is important for the kids to learn that they can exert power over themselves and the world. o Option C: Autonomy vs Shame and doubt is the second stage of Erik Erikson’s stages of psychosocial development. This stage occurs between the ages of 18 months to 3 years. According to Erikson, children at this stage are focused on developing a greater sense of control.  65. Question A nurse is making rounds taking vital signs. Which of the following vital signs is abnormal? o A. 11-year-old male: 90 BPM, 22 RPM, 100/70 mmHg o B. 13-year-old female: 105 BPM, 22 RPM, 105/50 mmHg o C. 5-year-old male: 102 BPM, 24 RPM, 90/65 mmHg o D. 6-year-old female: 100 BPM, 26 RPM, 90/70 mmHg Correct Answer: B. 13-year-old female: 105 BPM, 22 RPM, 105/50 mmHg The normal range of vital signs for 11 to 14-year-olds: Heart rate: 60-105 BPM; Respiratory rate: 12-20 CPM; Blood pressure: Systolic-85-120, diastolic- 55-80 mmHg; Body temperature: 98.0 degrees Fahrenheit (36.6 degrees Celsius) to 98.6 degrees Fahrenheit (37 degrees Celsius). The client’s diastolic pressure is lower than the normal range. Both her respiratory rate and heart rate are slightly increased. o Option A: Client’s heart rate and BP are within the normal range, respiratory rate slightly increased. o Option C: Normal range of vital signs for 3-5-year- olds: Heart rate: 80-120 BPM; Respiratory rate: 20-30 CPM; Blood pressure: 80-110 (systolic), 50-80 (diastolic). All vital signs are within the normal range. o Option D: Normal range of vital signs for 6-10-year- olds: Heart rate: 70-110 BPM; Respiratory rate: 15-30 CPM; Blood pressure: 85-120 (systolic), 55-80 (diastolic). All vital signs are within the normal range.  66. Question When you are taking a patient’s history, she tells you she has been depressed and is dealing with an anxiety disorder. Which of the following medications would the patient most likely be taking? o A. Amitriptyline (Elavil) o B. Calcitonin o C. Pergolide mesylate (Permax) o D. Verapamil (Calan) Correct Answer: A. Amitriptyline (Elavil) Amitriptyline (Elavil) is a tricyclic antidepressant and used to treat symptoms of depression. o Option B: Calcitonin is used to treat osteoporosis in women who have been in menopause. Calcitonin is a hormone that is produced in humans by the parafollicular cells (commonly known as C-cells) of the thyroid gland. Calcitonin is involved in helping to regulate levels of calcium and phosphate in the blood, opposing the action of the parathyroid hormone. o Option C: Permax (pergolide mesylate) is indicated as adjunctive treatment to levodopa/carbidopa in the management of the signs and symptoms of Parkinson†s disease. o Option D: Verapamil is used to treat high blood pressure and to control angina (chest pain). The immediate-release tablets are also used alone or with other medications to prevent and treat irregular heartbeats. Verapamil is in a class of medications called calcium-channel blockers. It works by relaxing the blood vessels so the heart does not have to pump as hard. It also increases the supply of blood and oxygen to the heart and slows electrical activity in the heart to control the heart rate. use as energy. When this occurs, the body starts burning fat and muscle for energy, causing a reduction in overall body weight. o Option A: Nausea and vomiting usually occur and may be associated with diffuse abdominal pain, decreased appetite, and anorexia. As the blood glucose levels rise and fall, the body’s metabolism can get interrupted and confused which can lead to a mixed feeling of nausea. o Option B: The incidence of increased water loss results in extreme thirst and dehydration. If our blood glucose levels are higher than they should be for prolonged periods of time, our kidneys will attempt to remove some of the excess glucose from the blood and excrete this as urine. Whilst the kidneys filter the blood in this way, water will also be removed from the blood and will need replenishing. This is why we tend to have increased thirst when our blood glucose levels run too high. o Option D: A characteristic sign of ketoacidosis is acetone (ketotic) breath or a fruity smell. When the body can’t get energy from glucose, it burns fat in its place. The fat-burning process creates a buildup of acids in the blood called ketones, which leads to DKA if untreated. Fruity-smelling breath is a sign of high levels of ketones in someone who already has diabetes.  70. Question A patient’s chart indicates a history of meningitis. Which of the following would you expect to see with this patient if this condition were acute? o A. Increased appetite o B. Vomiting o C. Fever o D. Poor tolerance of light Correct Answer: A. Increased appetite Loss of appetite would be expected. Most cases of meningitis are caused by an infectious agent that has colonized or established a localized infection elsewhere in the host. Potential sites of colonization or infection include the skin, the nasopharynx, the respiratory tract, the gastrointestinal (GI) tract, and the genitourinary tract. The organism invades the submucosa at these sites by circumventing host defenses (eg, physical barriers, local immunity, and phagocytes or macrophages). o Option B: Vomiting occurs in 35% of patients with meningitis. The brain is naturally protected from the body’s immune system by the barrier that the meninges create between the bloodstream and the brain. Normally, this protection is an advantage because the barrier prevents the immune system from attacking the brain. However, in meningitis, the blood- brain barrier can become disrupted; once bacteria or other organisms have found their way to the brain, they are somewhat isolated from the immune system and can spread. o Option C: The classic triad of meningitis consists of fever, nuchal rigidity, and altered mental status. When the body tries to fight the infection, the problem can worsen; blood vessels become leaky and allow fluid, WBCs, and other infection-fighting particles to enter the meninges and brain. This process, in turn, causes brain swelling and can eventually result in decreasing blood flow to parts of the brain, worsening the symptoms of infection. o Option D: Other symptoms include photalgia (photophobia): discomfort when the patient looks into bright lights. Depending on the severity of bacterial meningitis, the inflammatory process may remain confined to the subarachnoid space. In less severe forms, the pial barrier is not penetrated, and the underlying parenchyma remains intact. However, in more severe forms of bacterial meningitis, the pial barrier is breached, and the underlying parenchyma is invaded by the inflammatory process. Thus, bacterial meningitis may lead to widespread cortical destruction, particularly when left untreated.  71. Question A nurse if reviewing a patient’s chart and notices that the patient suffers from conjunctivitis. Which of the following microorganisms is related to this condition? o A. Yersinia pestis o B. Helicobacter pylori o C. Vibrio cholerae o D. Haemophilus aegyptius Correct Answer: D. Haemophilus aegyptius Haemophilus influenzae biogroup aegyptius (Hae) is a causative agent of acute and often purulent conjunctivitis, more commonly known as pink eye. o Option A: Plague is a disease that affects humans and other mammals. It is caused by the bacterium, Yersinia pestis. Y. pestis is primarily a disease of rodents or other wild mammals that usually is transmitted by fleas and often is fatal. Human disease is now rare and usually is associated with contact with rodents and their fleas. o Option B: Helicobacter pylori (H. pylori) infection occurs when H. pylori bacteria infect the stomach. Helicobacter pylori is a ubiquitous organism that is present in about 50% of the global population. Chronic infection with H pylori causes atrophic and even metaplastic changes in the stomach, and it has a known association with peptic ulcer disease. The most common route of H pylori infection is either oral-to- oral or fecal-to-oral contact. o Option C: Cholera, caused by the bacteria Vibrio cholerae, is rare in the United States and other industrialized nations. Cholera is an acute, diarrheal illness caused by infection of the intestine with the toxigenic bacterium Vibrio cholerae serogroup O1 or O139. An estimated 2.9 million cases and 95,000 deaths occur each year around the world. The infection is often mild or without symptoms, but can be severe. o B. ECG (electrocardiogram) o C. Thyroid function tests o D. CT scan Correct Answer: C. Thyroid function tests Weight gain and poor temperature tolerance indicate something may be wrong with the thyroid function. Thyroid function tests are designed to distinguish hyperthyroidism and hypothyroidism from the euthyroid state. To accomplish this task, direct measurements of the serum concentration of the two thyroid hormones—triiodothyronine (T3) and tetraiodothyronine (T4)— more commonly known as thyroxine, are extensively employed. o Option A: The complete blood count and metabolic profile may show abnormalities in patients with hypothyroidism. Thyroid dysfunction induces different effects on blood cells such as anemia, erythrocytosis, leukopenia, thrombocytopenia, and in rare cases causes’ pancytopenia. o Option B: Signs of hypothyroidism on ECG include sinus bradycardia, T-wave inversions (TWIs), QTc prolongation, and ventricular arrhythmias. Hypothyroidism can affect the cardiovascular system physiology and structure. These changes are often reflected on ECG. o Option D: Ultrasonography of the neck and thyroid can be used to detect nodules and infiltrative disease. High-resolution ultrasonography (USG) is the most sensitive imaging modality available for examination of the thyroid gland and associated abnormalities. Ultrasound scanning is non-invasive, widely available, less expensive, and does not use any ionizing radiation. Further, real-time ultrasound imaging helps to guide diagnostic and therapeutic interventional procedures in cases of thyroid disease.  75. Question A 20-year-old female attending college is found unconscious in her dorm room. She has a fever and a noticeable rash. She has just been admitted to the hospital. Which of the following tests is most likely to be performed first? o A. Blood sugar check o B. CT scan o C. Blood cultures o D. Arterial blood gases Correct Answer: C. Blood cultures Blood cultures would be performed to investigate the fever and rash symptoms. A blood culture is a test that checks for foreign invaders like bacteria, yeast, and other microorganisms in the blood. Having these pathogens in the bloodstream can be a sign of a blood infection, a condition known as bacteremia. A positive blood culture means that there are bacteria in the blood. o Option A: Blood sugar check is necessary for clients who are suspected of having an increase in blood sugar and whose symptoms include excessive thirst and hunger, and excessive sweating. o Option B: CT scan is unnecessary at the time for a client with fever and rash. A computerized tomography (CT) scan combines a series of X-ray images taken from different angles around the body and uses computer processing to create cross- sectional images (slices) of the bones, blood vessels, and soft tissues inside the body. CT scan images provide more detailed information than plain X-rays do. o Option D: An arterial blood gas (ABG) test measures oxygen and carbon dioxide levels in the blood. It also measures the body’s acid-base (pH) level, which is usually in balance when healthy.
