NCLEX 4100 EXAM 4 QUESTIONS WITH 100% CORRECT ANSWERS 2024 A client receiving a transfusion of packed red blood cells (PRBCs) begins to vomit. The client's blood pressure is 90/50 mm Hg from a baseline of 125/78 mm Hg. The client's temperature is 100.8°F (38.2°C) orally from a baseline of 99.2°F (37.3°C) orally. The nurse determines that the client may be experiencing which complication of a blood transfusion? 1.Septicemia 2.Hyperkalemia 3.Circulatory overload 4.Delayed transfusion reaction - Correct Answer-1 Rationale:Septicemia occurs with the transfusion of blood contaminated with microorganisms. Signs include chills, fever, vomiting, diarrhea, hypotension, and the development of shock. Hyperkalemia causes weakness, paresthesias, abdominal cramps, diarrhea, and dysrhythmias. Circulatory overload causes cough, dyspnea, chest pain, wheezing, tachycardia, and hypertension. A delayed transfusion reaction can occur days to years after a transfusion. Signs include fever, mild jaundice, and a decreased hematocrit level. The nurse is caring for a client with meningitis and implements which transmission-based precautions for this client? 1.Private room or cohort client 2.Personal respiratory protection device 3.Private room with negative airflow pressure 4.Mask worn by staff when the client needs to leave the room - Correct Answer-1 Rationale:Meningitis is transmitted by droplet infection. Precautions for this disease include a private room or cohort client and use of a standard precaution mask. Private negative airflow pressure rooms and personal respiratory protection devices are required for clients with airborne disease such as tuberculosis. When appropriate, a mask must be worn by the client and not the staff when the client leaves the room. The nurse is assigned to care for an 8-year-old child with a diagnosis of a basilar skull fracture. The nurse reviews the health care provider's (HCP's) prescriptions and should contact the HCP to question which prescription? neurosurgery, trauma, infection of the sinus or ears, or systemic infections. Meningitis is diagnosed by testing CSF obtained by lumbar puncture. In the case of bacterial meningitis, findings usually include an elevated pressure; turbid or cloudy CSF; and elevated leukocyte, elevated protein, and decreased glucose levels. An adult client was burned in an explosion. The burn initially affected the client's entire face (anterior half of the head) and the upper half of the anterior torso, and there were circumferential burns to the lower half of both arms. The client's clothes caught on fire, and the client ran, causing subsequent burn injuries to the posterior surface of the head and the upper half of the posterior torso. Using the rule of nines, what would be the extent of the burn injury? 1.18% 2.24% 3.36% 4.48% - Correct Answer-3 Rationale:According to the rule of nines, with the initial burn, the anterior half of the head equals 4.5%, the upper half of the anterior torso equals 9%, and the lower half of both arms equals 9%. The subsequent burn included the posterior half of the head, equaling 4.5%, and the upper half of posterior torso, equaling 9%. This totals 36%. The nurse is preparing to care for a burn client scheduled for an escharotomy procedure being performed for a third-degree circumferential arm burn. The nurse understands that which finding is the anticipated therapeutic outcome of the escharotomy? 1.Return of distal pulses 2.Brisk bleeding from the site 3.Decreasing edema formation 4.Formation of granulation tissue - Correct Answer-1 Rationale:Escharotomies are performed to relieve the compartment syndrome that can occur when edema forms under nondistensible eschar in a circumferential third-degree burn. The escharotomy releases the tourniquet-like compression around the arm. Escharotomies are performed through avascular eschar to subcutaneous fat. Although bleeding may occur from the site, it is considered a complication rather than an anticipated therapeutic outcome. Usually, direct pressure with a bulky dressing and elevation control the bleeding, but occasionally an artery is damaged and may require ligation. Escharotomy does not affect the formation of edema. Formation of granulation tissue is not the intent of an escharotomy. The nurse is caring for a client who sustained superficial partial-thickness burns on the anterior lower legs and anterior thorax. Which finding does the nurse expect to note during the resuscitation/emergent phase of the burn injury? 1.Decreased heart rate 2.Increased urinary output 3.Increased blood pressure 4.Elevated hematocrit levels - Correct Answer-4 Rationale:The resuscitation/emergent phase begins at the time of injury and ends with the restoration of capillary permeability, usually at 48 to 72 hours following the injury. During the resuscitation/emergent phase, the hematocrit level increases to above normal because of hemoconcentration from the large fluid shifts. Hematocrit levels of 50% to 55% (0.50 to 0.55) are expected during the first 24 hours after injury, with return to normal by 36 hours after injury. Initially, blood is shunted away from the kidneys and renal perfusion and glomerular filtration are decreased, resulting in low urine output. The burn client is prone to hypovolemia and the body attempts to compensate by 4.Squeezing of the sternocleidomastoid muscle - Correct Answer-2 Rationale:Nail bed pressure tests a basic motor and sensory peripheral response. Cerebral responses to pain are tested using a sternal rub, placing upward pressure on the orbital rim, or squeezing the clavicle or sternocleidomastoid muscle. The nurse is caring for the client with increased intracranial pressure. The nurse would note which trend in vital signs if the intracranial pressure is rising? 1.Increasing temperature, increasing pulse, increasing respirations, decreasing blood pressure 2.Increasing temperature, decreasing pulse, decreasing respirations, increasing blood pressure 3.Decreasing temperature, decreasing pulse, increasing respirations, decreasing blood pressure 4.Decreasing temperature, increasing pulse, decreasing respirations, increasing blood pressure - Correct Answer-2 Rationale:A change in vital signs may be a late sign of increased intracranial pressure. Trends include increasing temperature and blood pressure and decreasing pulse and respirations. Respiratory irregularities also may occur. A client recovering from a head injury is participating in care. The nurse determines that the client understands measures to prevent elevations in intracranial pressure if the nurse observes the client doing which activity? 1.Blowing the nose 2.Isometric exercises 3.Coughing vigorously 4.Exhaling during repositioning - Correct Answer-4 Rationale:Activities that increase intrathoracic and intraabdominal pressures cause an indirect elevation of the intracranial pressure. Some of these activities include isometric exercises, Valsalva's maneuver, coughing, sneezing, and blowing the nose. Exhaling during activities such as repositioning or pulling up in bed opens the glottis, which prevents intrathoracic pressure from rising. A client has clear fluid leaking from the nose following a basilar skull fracture. Which finding would alert the nurse that cerebrospinal fluid is present? 1.Fluid is clear and tests negative for glucose. 2.Fluid is grossly bloody in appearance and has a pH of 6. 3.Fluid clumps together on the dressing and has a pH of 7. 4.Fluid separates into concentric rings and tests positive for glucose. - Correct Answer-4 Rationale:Leakage of cerebrospinal fluid (CSF) from the ears or nose may accompany basilar skull fracture. CSF can be distinguished from other body fluids because the drainage will separate into bloody and yellow concentric rings on dressing material, called a halo sign. The fluid also tests positive for glucose. The nurse is evaluating the neurological signs of a client in spinal shock following spinal cord injury. Which observation indicates that spinal shock persists? 1.Hyperreflexia 2.Positive reflexes 3.Flaccid paralysis 4.Reflex emptying of the bladder - Correct Answer-3 Rationale:Resolution of spinal shock is occurring when there is return of reflexes (especially flexors to noxious cutaneous stimuli), a state of hyperreflexia rather than flaccidity, and reflex emptying of the bladder. 3.Providing information, giving positive feedback, and encouraging relaxation 4.Providing intravenously administered sedatives, reducing distractions, and limiting visitors - Correct Answer-3 Rationale:The client with Guillain-Barré syndrome experiences fear and anxiety from the ascending paralysis and sudden onset of the disorder. The nurse can alleviate these fears by providing accurate information about the client's condition, giving expert care and positive feedback to the client, and encouraging relaxation and distraction. The family can become involved with selected care activities and provide diversion for the client as well. The nurse is evaluating the status of a client who had a craniotomy 3 days ago. Which assessment finding would indicate that the client is developing meningitis as a complication of surgery? 1.A negative Kernig's sign 2.Absence of nuchal rigidity 3.A positive Brudzinski's sign 4.A Glasgow Coma Scale score of 15 - Correct Answer-3 Rationale:Signs of meningeal irritation compatible with meningitis include nuchal rigidity, a positive Brudzinski's sign, and positive Kernig's sign. Nuchal rigidity is characterized by a stiff neck and soreness, which is especially noticeable when the neck is flexed. Kernig's sign is positive when the client feels pain and spasm of the hamstring muscles when the leg is fully flexed at the knee and hip. Brudzinski's sign is positive when the client flexes the hips and knees in response to the nurse gently flexing the head and neck onto the chest. A Glasgow Coma Scale score of 15 is a perfect score and indicates that the client is awake and alert, with no neurological deficits. The nurse has completed discharge instructions for a client with application of a halo device. Which statement indicates that the client needs further clarification of the instructions? 1."I will use a straw for drinking." 2."I will drive only during the daytime." 3."I will be careful because the device alters balance." 4."I will wash the skin daily under the lamb's wool liner of the vest." - Correct Answer-2 Rationale:The halo device alters balance and can cause fatigue because of its weight. The client should cleanse the skin daily under the vest to protect the skin from ulceration and should avoid the use of powder or lotions. The liner should be changed if odor becomes a problem. The client should have food cut into small pieces to facilitate chewing and use a straw for drinking. Pin care is done as instructed. The client cannot drive at all because the device impairs the range of vision. The nurse is admitting a client with Guillain-Barré syndrome to the nursing unit. The client has ascending paralysis to the level of the waist. Knowing the complications of the disorder, the nurse should bring which most essential items into the client's room? 1.Nebulizer and pulse oximeter 2.Blood pressure cuff and flashlight 3.Flashlight and incentive spirometer 4.Electrocardiographic monitoring electrodes and intubation tray - Correct Answer-4 Rationale:The client with Guillain-Barré syndrome is at risk for respiratory failure because of ascending paralysis. An intubation tray should be available for use. Another complication of this syndrome is cardiac dysrhythmias, which necessitates the use of electrocardiographic monitoring. client's trunk is tan, dry, and hard. It is edematous but not very painful. The nurse determines that this client's burn should be classified as which type? 1.Superficial 2.Full-thickness 3.Deep partial-thickness 4.Partial-thickness superficial - Correct Answer-2 Rationale:Full-thickness burns involve the epidermis, the full dermis, and some of the subcutaneous fat layer. The burn appears to be a tan or fawn color, with skin that is hard, dry, and inelastic. Edema is severe, and the accumulated fluid compresses tissue underneath because of eschar formation. Some nerve endings have been damaged, and the area may be insensitive to touch, with little or no pain. A client who is being evaluated for thermal burn injuries to the arms and legs complains of thirst and asks the nurse for a drink. Which action by the nurse is most appropriate? 1.Allow the client to have full liquids. 2.Give the client small glasses of clear liquids. 3.Order the client a full meal tray with extra liquids. 4.Keep the client on NPO (nothing by mouth) status. - Correct Answer-4 Rationale:The client should be maintained on NPO status because burn injuries frequently result in paralytic ileus. The client also should be told that fluids could cause vomiting because of the effect of the burn injury on gastrointestinal tract functioning. Mouth care should be given as appropriate to alleviate the sensation of thirst. A client is seen in the ambulatory care clinic for a superficial burn to the arm. On assessing the skin at the burn injury, what will the nurse observe? 1.White color 2.Pink or red color 3.Weeping blisters 4.Insensitivity to pain and cold - Correct Answer-2 Rationale:Superficial burns are pink or red without any blistering. The skin blanches to touch, may be edematous and painful, and heals on its own, usually within 1 week. A white color characterizes deep partial-thickness burns. Weeping blisters characterize partial-thickness superficial burns. Deep full-thickness burns are associated with insensitivity to pain and cold. The nurse is caring for a client who was admitted to the burn unit after sustaining a burn injury covering 30% of the body. What is the most appropriate time frame for the emergent phase? 1.The entire period of time during which rehabilitation occurs 2.The period from the time the client is stable to the time when all burns are covered with skin 3.The period from the time the burn was incurred to the time when the client is admitted to the hospital 4.The period from the time the burn was incurred to the time when the client is considered physiologically stable - Correct Answer-4 Rationale:The emergent phase of burn care generally extends from the time the burn injury is incurred until the time when the client is considered physiologically stable. The acute phase lasts until all full-thickness burns are covered with skin. The rehabilitation period lasts approximately 5 years for an adult and includes reintegration into society. The nurse is planning care for a client who suffered a burn injury and has a negative self-image related to keloid The nurse is planning care for a client returning from the operating room after having an autograft applied to the right lower extremity. Which nursing intervention is focused on promoting graft "take"? 1.Monitor temperature every 4 hours. 2.Leave the dressing intact for 3 to 5 days. 3.Maintain the right lower extremity in a dependent position. 4.Apply an ice pack to the site to decrease edema formation. - Correct Answer-2 Rationale:After surgery, graft sites are immobilized with bulky cotton pressure dressing for 3 to 5 days to allow vascularization, or "take," of the newly grafted skin. Dressings should not be disturbed. Elevation and complete rest of the grafted area is required to allow blood vessels to connect the graft with the wound bed. Any activity that might cause movement of the dressing against the body and separation of the graft from the wound is prohibited, such as application of an ice pack. Additionally, cold promotes vasoconstriction. The nurse in the neurological unit is caring for a client who was in a motor vehicle crash and sustained a blunt head injury. On assessment of the client, the nurse notes the presence of bloody drainage from the nose. Which nursing action is most appropriate? 1.Insert nasal packing. 2.Document the findings. 3.Contact the health care provider (HCP). 4.Monitor the client's blood pressure and check for signs of increased intracranial pressure. - Correct Answer-3 Rationale:Bloody or clear drainage from either the nasal or the auditory canal after head trauma could indicate a cerebrospinal fluid leak. The appropriate nursing action is to notify the HCP, because this finding requires immediate intervention. The remaining options are inappropriate nursing actions in this situation. The nurse is planning care for a client who displays confusion secondary to a neurological problem. Which approaches by the nurse would be helpful in assisting this client? Select all that apply. 1.Providing sensory cues 2.Giving simple, clear directions 3.Providing a stable environment 4.Keeping family pictures at the bedside 5.Encouraging family members to visit at the same time - Correct Answer-1, 2, 3, 4 Rationale:Clients with cognitive impairment from neurological dysfunction respond best to a stable environment that is limited in amount and type of sensory input. The nurse can provide sensory cues and give clear, simple directions in a positive manner. Confusion can be minimized by reducing environmental stimuli (such as television or multiple visitors) and by keeping familiar personal articles (such as family pictures) at the bedside. Members of the family of an unconscious client with increased intracranial pressure are talking at the client's bedside. They are discussing the client's condition and wondering whether the client will ever recover. The nurse intervenes on the basis of which interpretation? 1.It is possible the client can hear the family. 2.The family needs immediate crisis intervention. 3.The client might have wanted a visit from the hospital chaplain. 4.The family could benefit from a conference with the health care provider. - Correct Answer-1 The nurse would intervene and provide teaching to the student if the student included which home care instruction? 1.Sounds will not be heard clearly unless they are loud. 2.Obtain assistance with ambulation if the client is lightheaded. 3.Tub bath or shower is permitted, but the scalp is kept dry until the sutures are removed. 4.Use a check-off system for administering anticonvulsant medications to avoid missing doses. - Correct Answer-1 Rationale:The postcraniotomy client typically is sensitive to loud noises and can find them excessively irritating. Control of environmental noise by others will be helpful for this client. Seizures are a potential complication that may occur for up to 1 year after surgery. For this reason, the client must diligently take anticonvulsant medications. The client and family are encouraged to keep track of the doses administered. The family should learn seizure precautions and should accompany the client during ambulation if dizziness or seizures tend to occur. The suture line is kept dry until sutures are removed to prevent infection. The nurse has made a judgment that a client who had a craniotomy is experiencing a problem with body image. The nurse develops goals for the client but determines that the client has not met the outcome criteria by discharge if the client performs which action? 1.Wears a turban to cover the incision 2.Indicates that facial puffiness will be a permanent problem 3.Verbalizes that periorbital bruising will disappear over time 4.States an intention to purchase a hairpiece until hair has grown back - Correct Answer-2 Rationale:After craniotomy, clients may experience difficulty with altered personal appearance. The nurse can help by listening to the client's concerns and by clarifying any misconceptions about facial edema, periorbital bruising, and hair loss (all of which are temporary). The nurse can encourage the client to participate in self-grooming and use personal articles of clothing. Finally, the nurse can suggest the use of a turban, followed by a hairpiece, to help the client adapt to the temporary change in appearance. A client with a spinal cord injury at the level of C5 has a weakened respiratory effort and ineffective cough and is using accessory neck muscles in breathing. The nurse carefully monitors the client and suspects the presence of which problem? 1.Altered breathing pattern 2.Increased likelihood of injury 3.Ineffective oxygen consumption 4.Increased susceptibility to aspiration - Correct Answer-1 Rationale:Altered breathing pattern indicates that the respiratory rate, depth, rhythm, timing, or chest wall movements are insufficient for optimal ventilation of the client. This is a risk for clients with spinal cord injury in the lower cervical area. Ineffective oxygen consumption occurs when oxygenation or carbon dioxide elimination is altered at the alveolar-capillary membrane. Increased susceptibility to aspiration and increased likelihood of injury are unrelated to the subject of the question. A client with a spinal cord injury becomes angry and belligerent whenever the nurse tries to administer care. The nurse should perform which action? 1.Ask the family to deliver the care. 2.Leave the client alone until ready to participate. 3.Advise the client that rehabilitation progresses more quickly with cooperation. Rationale:To manage constipation, the client should take in a high-fiber diet, bulk formers, and stool softeners. A fluid intake of 2000 mL/day is recommended. The client should initiate a bowel movement on an every-other-day basis and should sit on the toilet or commode. This should be done approximately 45 minutes after the largest meal of the day to take advantage of the gastrocolic reflex. A glycerin suppository, bisacodyl suppository, or digital stimulation may be used to initiate the process. Laxatives and enemas should be avoided whenever possible because they lead to dependence. A client with a neurological problem is experiencing hyperthermia. Which measures would be appropriate for the nurse to use in trying to lower the client's body temperature? Select all that apply. 1.Giving tepid sponge baths 2.Applying a hypothermia blanket 3.Covering the client with blankets 4.Administering acetaminophen per protocol 5.Placing ice packs over the client's abdomen and in the axilla and groin - Correct Answer-1, 2, 5 Rationale:Standard measures to lower body temperature include removing bed covers, providing cool sponge baths, using an electric fan in the room, administering acetaminophen, and placing a hypothermia blanket under the client. Ice packs are not used because they could cause shivering, which increases cellular oxygen demands, with the potential for increased intracranial pressure. Which intervention should the nurse include in a postoperative teaching plan for a client who underwent a spinal fusion and will be wearing a brace? 1.Tell the client to inspect the environment for safety hazards. 2.Inform the client about the importance of sitting as much as possible. 3.Inform the client that lotions and body powders can be used for skin breakdown. 4.Instruct the client to tighten the brace during meals and to loosen it for the first 30 minutes after each meal. - Correct Answer-1 Rationale:The client must inspect the environment for safety hazards. The client is instructed in the importance of avoiding prolonged sitting and standing. Powders and lotions should not be used because they may irritate the skin. The client should be taught to loosen the brace during meals and for 30 minutes after each meal. The client may have difficulty eating if the brace is too tight. Loosening the brace after each meal will allow adequate nutritional intake and promote comfort. The nurse is preparing to care for a client after a lumbar puncture. The nurse should plan to place the client in which best position following the procedure? 1.Prone in semi Fowler's position 2.Supine in semi Fowler's position 3.Prone with a small pillow under the abdomen 4.Lateral with the head slightly lower than the rest of the body - Correct Answer-3 Rationale:After the procedure, the client assumes a flat position. If the client is able, a prone position with a pillow under the abdomen is the best position. This position helps reduce cerebrospinal fluid leakage and decreases the likelihood of post-lumbar puncture headache. The remaining options are incorrect. The student nurse develops a plan of care for a client after a lumbar puncture. The nursing instructor corrects the student head injury. The nurse understands that the neurologist would avoid performing the oculocephalic response (doll's eyes maneuver) if which condition is present in the client? 1.Dilated pupils 2.Lumbar trauma 3.A cervical cord injury 4.Altered level of consciousness - Correct Answer-3 Rationale:In an unconscious client, eye movements are an indication of brainstem activity and are tested by the oculocephalic response. When the doll's eyes maneuver is intact, the eyes move in the opposite direction when the head is turned. Abnormal responses include movement of the eyes in the same direction as that for the head and maintenance of a midline position of the eyes when the head is turned. An abnormal response indicates a disruption in the processing of information through the brainstem. Contraindications to performing this test include cervical-level spinal cord injuries and severely increased intracranial pressure. The nurse is performing the oculocephalic response (doll's eyes maneuver) on an unconscious client. The nurse turns the client's head and notes movement of the eyes in the same direction as the head. How should the nurse document these findings? 1.Normal 2.Abnormal 3.Insignificant 4.Inconclusive - Correct Answer-2 Rationale:In an unconscious client, eye movements are an indication of brainstem activity and are tested by the oculocephalic response. When the doll's eyes maneuver is intact, the eyes move in the opposite direction when the head is turned. Abnormal responses include movement of the eyes in the same direction as the head and maintenance of a midline position of the eyes when the head is turned. An abnormal response indicates a disruption in the processing of information through the brainstem. The nurse develops a plan of care for a client with a brain aneurysm who will be placed on aneurysm precautions. Which interventions should be included in the plan? Select all that apply. 1.Leave the lights on in the client's room at night. 2.Place a blood pressure cuff at the client's bedside. 3.Close the shades in the client's room during the day. 4.Allow the client to drink 1 cup of caffeinated coffee a day. 5.Allow the client to ambulate 4 times a day with assistance. - Correct Answer-2, 3 Rationale:Aneurysm precautions include placing the client on bed rest in a quiet setting. The use of lights is kept to a minimum to prevent environmental stimulation. The nurse should monitor the blood pressure and note any changes that could indicate rupture. Any activity, such as pushing, pulling, sneezing, or straining, that increases the blood pressure or impedes venous return from the brain is prohibited. The nurse provides physical care to minimize increases in blood pressure. Visitors, radio, television, and reading materials are restricted or limited. Stimulants, such as nicotine and coffee and other caffeine-containing products, are prohibited. Decaffeinated coffee or tea may be used. The nurse is preparing a plan of care for a client with a diagnosis of amyotrophic lateral sclerosis (ALS). On assessment, the nurse notes that the client is severely dysphagic. Which intervention should be included in the care plan for this client? Select all that apply. The nurse is caring for a client after a craniotomy and monitors the client for signs of increased intracranial pressure (ICP). Which finding, if noted in the client, would indicate an early sign of increased ICP? 1.Confusion 2.Bradycardia 3.Sluggish pupils 4.A widened pulse pressure - Correct Answer-1 Rationale:Early manifestations of increased ICP are subtle and often may be transient, lasting for only a few minutes in some cases. These early clinical manifestations include episodes of confusion, drowsiness, and slight pupillary and breathing changes. Later manifestations include a further decrease in the level of consciousness, a widened pulse pressure, and bradycardia. Cheyne-Stokes respiratory pattern, or a hyperventilation respiratory pattern, and pupillary sluggishness and dilatation appear in the late stages. A client is undergoing fluid replacement after being burned on 20% of her body 12 hours ago. The nursing assessment reveals a blood pressure of 90/50 mm Hg, a pulse rate of 110 beats/minute, and a urine output of 20 mL over the past hour. The nurse reports the findings to the health care provider (HCP) and anticipates which prescription? 1.Transfusing 1 unit of packed red blood cells 2.Administering a diuretic to increase urine output 3.Increasing the amount of intravenous (IV) lactated Ringer's solution administered per hour 4.Changing the IV lactated Ringer's solution to one that contains 5% dextrose in water - Correct Answer-3 Rationale:Fluid management during the first 24 hours following a burn injury generally includes the infusion of (usually) lactated Ringer's solution. Lactated Ringer's solution is an isotonic solution that contains electrolytes that will maintain fluid volume in the circulation. Fluid resuscitation is determined by urine output and hourly urine output should be at least 30 mL/hour. The client's urine output is indicative of insufficient fluid resuscitation, which places the client at risk for inadequate perfusion of the brain, heart, kidneys, and other body organs. Therefore, the HCP would prescribe an increase in the amount of IV lactated Ringer's solution administered per hour. There is nothing in the situation that calls for blood replacement, which is not used for fluid therapy for burn injuries. Administering a diuretic would not correct the problem because fluid replacement is needed. Diuretics promote the removal of the circulating volume, thereby further compromising the inadequate tissue perfusion. Intravenous 5% dextrose solution is isotonic before administered but is hypotonic once the dextrose is metabolized. Hypotonic solutions are not appropriate for fluid resuscitation of a client with significant burn injuries. The nurse is monitoring a client for signs and symptoms related to superior vena cava syndrome. Which is an early sign of this oncological emergency? 1.Cyanosis 2.Arm edema 3.Periorbital edema 4.Mental status changes - Correct Answer-3 Rationale:Superior vena cava syndrome occurs when the superior vena cava is compressed or obstructed by tumor growth. Early signs and symptoms generally occur in the morning and include edema of the face, especially around the eyes, and client complaints of tightness of a shirt or blouse collar. As the compression worsens, the client experiences edema of the hands and arms. Cyanosis and mental status changes are late signs. complication of cardiogenic shock increases the recovery period for healing. Paced activities with planned rest periods will decrease the chance of experiencing angina or delayed healing. It is best to allow the meal to settle prior to activity in order to improve circulation to the heart during exercise. Epigastric pain or a weight gain of 8 pounds (3.6 kg) is significant and should be reported to the health care provider, at which point follow-up should occur. The nurse is reviewing the record of a client with a suspected diagnosis of Huntington's disease. The nurse should expect to note documentation of which early symptom of this disease? 1.Aphasia 2.Agnosia 3.Difficulty with swallowing 4.Balance and coordination problems - Correct Answer-4 Rationale:Early symptoms of Huntington's disease include restlessness, forgetfulness, clumsiness, falls, balance and coordination problems, altered speech, and altered handwriting. Difficulty with swallowing occurs in the later stages. Aphasia and agnosia do not occur. The home health nurse is visiting a client with a diagnosis of multiple sclerosis. The client has been taking oxybutynin. The nurse evaluates the effectiveness of the medication by asking the client which assessment question? 1."Are you consistently fatigued?" 2."Are you having muscle spasms?" 3."Are you getting up at night to urinate?" 4."Are you having normal bowel movements?" - Correct Answer-3 Rationale:Oxybutynin is an antispasmodic used to relieve symptoms of urinary urgency, frequency, nocturia, and incontinence in clients with uninhibited or reflex neurogenic bladder. Expected effects include improved urinary control and decreased urinary frequency, incontinence, and nocturia. The questions in the remaining options are unrelated to the use of this medication. The nurse is preparing for the admission of a client with a suspected diagnosis of Guillain-Barré syndrome. When the client arrives at the nursing unit, the nurse reviews the health care provider's documentation. The nurse expects to note documentation of which hallmark clinical manifestation of this syndrome? 1.Multifocal seizures 2.Altered level of consciousness 3.Abrupt onset of a fever and headache 4.Development of progressive muscle weakness - Correct Answer-4 Rationale:A hallmark clinical manifestation of Guillain-Barré syndrome is progressive muscle weakness that develops rapidly. Seizures are not normally associated with this disorder. The client does not have symptoms such as a fever or headache. Cerebral function, level of consciousness, and pupillary responses are normal. A thymectomy accomplished via a median sternotomy approach is performed in a client with a diagnosis of myasthenia gravis. The nurse creates a postoperative plan of care for the client that should include which intervention? 1.Monitor the chest tube drainage. 2.Restrict visitors for 24 hours postoperatively. 3.Maintain intravenous infusion of lactated Ringer's solution. 4.Avoid administering pain medication to prevent respiratory depression. - Correct Answer-1 is positioned with no pinching or pressure on paralyzed body parts and that the client will be sufficiently warm. A client who had cranial surgery 5 days earlier to remove a brain tumor has a few cognitive deficits and does not seem to be progressing as quickly as the client or family had hoped. The nurse plans to implement which approach as most helpful to the client and family at this time? 1.Emphasize progress in a realistic manner. 2.Set high goals to give the client something to "aim for." 3.Tell the family to be extremely optimistic with the client. 4.Inform the client and family of standardized goals of care. - Correct Answer-1 Rationale:The most helpful approach by the nurse is to emphasize progress that is being made in a realistic manner. The nurse does not offer false hope but does provide factual information in a clear and positive manner. The nurse encourages the family to be realistic in their expectations and attitudes. The plan of care should be individualized for each client. A client arrives in the hospital emergency department with a closed head injury to the right side of the head caused by an assault with a baseball bat. The nurse assesses the client neurologically, looking primarily for motor response deficits that involve which area? 1.The left side of the body 2.The right side of the body 3.Both sides of the body equally 4.Cranial nerves only, such as speech and pupillary response - Correct Answer-1 Rationale:Motor responses such as weakness and decreased movement will be seen on the side of the body that is opposite an area of head injury. Contralateral deficits result from compression of the cortex of the brain or the pyramidal tracts. Depending on the severity of the injury, the client may have a variety of neurological deficits. The nurse has a prescription to begin aneurysm precautions for a client with a subarachnoid hemorrhage secondary to aneurysm rupture. The nurse would plan to incorporate which intervention in controlling the environment for this client? 1.Keep the window blinds open. 2.Turn on a small spotlight above the client's head. 3.Make sure the door to the room is open at all times. 4.Prohibit or limit the use of a radio or television and reading. - Correct Answer-4 Rationale:Environmental stimuli are kept to a minimum with subarachnoid precautions to prevent or minimize increases in intracranial pressure. For this reason, lighting is reduced by closing window blinds and keeping the door to the client's room shut. Overhead lighting also is avoided for the same reason. The nurse prohibits television, radio, and reading unless this is so stressful for the client that it would be counterproductive. In that instance, minimal amounts of stimuli by these means are allowed with approval of the health care provider. The nurse is caring for a client who is on bed rest as part of aneurysm precautions. The nurse should avoid doing which action when giving respiratory care to this client? 1.Encouraging hourly coughing 2.Assisting with incentive spirometer 3.Encouraging hourly deep breathing as a Stryker frame, which allows the nurse to turn the client to prevent complications of immobility while maintaining alignment of the spine. If a Stryker frame is not available, a firm mattress with a bed board under it should be used. The remaining options are incorrect and potentially harmful interventions. A client with myasthenia gravis is having difficulty with airway clearance and difficulty with maintaining an effective breathing pattern. The nurse should keep which most important items available at the client's bedside? 1.Oxygen and metered-dose inhaler 2.Ambu bag and suction equipment 3.Pulse oximeter and cardiac monitor 4.Incentive spirometer and cough pillow - Correct Answer-2 Rationale:The client with myasthenia gravis may experience episodes of respiratory distress if excessively fatigued or with development of myasthenic or cholinergic crisis. For this reason, an Ambu bag, intubation tray, and suction equipment should be available at the bedside. The nurse has instructed a client with myasthenia gravis about strategies for self-management at home. The nurse determines a need for further teaching if the client makes which statement? 1."Here's the MedicAlert bracelet I obtained." 2."I should take my medications an hour before mealtime." 3."Going to the beach will be a nice, relaxing form of activity." 4."I've made arrangements to get a portable resuscitation bag and home suction equipment." - Correct Answer-3 Rationale:Most ongoing treatment for myasthenia gravis is done in outpatient settings, and the client must be aware of the lifestyle changes needed to maintain independence. The client should carry medical identification about the presence of the condition. Taking medications an hour before mealtime gives greater muscle strength for chewing and is indicated. The client should have portable suction equipment and a portable resuscitation bag available in case of respiratory distress. The client should avoid situations and other factors, including stress, infection, heat, surgery, and alcohol, that could worsen the symptoms. A client is admitted with an exacerbation of multiple sclerosis. The nurse is assessing the client for possible precipitating risk factors. Which factor, if reported by the client, should the nurse identify as being unrelated to the exacerbation? 1.Annual influenza vaccination 2.Ingestion of increased fruits and vegetables 3.An established routine of walking 2 miles each evening 4.A recent period of extreme outside ambient temperatures - Correct Answer-2 Rationale:The onset or exacerbation of multiple sclerosis can be preceded by a number of different factors, including physical stress (e.g., vaccination, excessive exercise), emotional stress, fatigue, infection, physical injury, pregnancy, extremes in environmental temperature, and high humidity. No methods of primary prevention are known. Intake of fruits and vegetables is a healthy and an unrelated item. A client with multiple sclerosis is experiencing muscle weakness, spasticity, and an ataxic gait. On the basis of this information, the nurse should include which client problem in the plan of care? 1.Inability to care for self 2.Interruption in skin integrity 1.Place the client in Sims' position. 2.Change the drainage tubing every 48 hours. 3.Level the transducer at the lowest point of the ear. 4.Use strict aseptic technique when touching the monitoring system. - Correct Answer-4 Rationale:Because there is a foreign body embedded in the client's brain, vigilant aseptic technique should be implemented. Sims' is a side-lying, flat position. With a client who has increased ICP, the head of the bed should be elevated at least 30 degrees to improve jugular outflow. The drainage tubing should not be routinely changed. It should remain for the duration of the monitoring. To obtain accurate ICP pressure readings, the transducer is zeroed at the level of the foramen of Monro, which is approximated by placing the transducer 1 inch above the level of the ear. Serial ICP readings should be done with the client's head in the same position. A client with a traumatic brain injury is on mechanical ventilation. The nurse promotes normal intracranial pressure (ICP) by ensuring that the client's arterial blood gas (ABG) results are within which ranges? 1.PaO2 60 to 100 mm Hg (60 to 100 mm Hg), PaCo2 25 to 30 mm Hg (25 to 30 mm Hg) 2.PaO2 60 to 100 mm Hg (60 to 100 mm Hg), PaCo2 30 to 35 mm Hg (30 to 35 mm Hg) 3.PaO2 80 to 100 mm Hg (80 to 100 mm Hg), PaCo2 25 to 30 mm Hg (25 to 30 mm Hg) 4.PaO2 80 to 100 mm Hg (80 to 100 mm Hg), PaCo2 35 to 38 mm Hg (35 to 38 mm Hg) - Correct Answer-4 Rationale:The goal is to maintain the partial pressure of arterial carbon dioxide (PaCo2) at 35 to 38 mm Hg (35 to 38 mm Hg). Carbon dioxide is a very potent vasodilator that can contribute to increases in ICP. The PaO2 is not allowed to fall below 80 mm Hg (80 mm Hg), to prevent cerebral vasodilation from hypoxemia, which can also result in an increase in ICP. Therefore, the remaining options are incorrect. The nurse is providing care to a client with increased intracranial pressure (ICP). Which approach is beneficial in controlling the client's ICP from an environmental viewpoint? 1.Reduce environmental noise. 2.Allow visitors as desired by the client and family. 3.Awaken the client every 2 to 3 hours to monitor mental status. 4.Cluster nursing activities to reduce the number of interruptions. - Correct Answer-1 Rationale:Nursing interventions to control ICP include maintaining a calm, quiet, and restful environment. Environmental noise should be kept at a minimum. Visiting should be monitored to avoid emotional stress and interruption of sleep. Interventions should be spaced out over the shift to minimize the risk of a sustained rise in ICP. A client was seen and treated in the hospital emergency department for a concussion. The nurse determines that the family needs further teaching if they verbalize to call the health care provider (HCP) for which client sign or symptom? 1.Vomiting 2.Minor headache 3.Difficulty speaking 4.Difficulty awakening - Correct Answer-2 Rationale:A concussion after head injury is a temporary loss of consciousness (from a few seconds to a few minutes) without evidence of structural damage. After concussion, the family is correct understanding of home care instructions to maintain health with this neurological degenerative disease. The nurse is performing an assessment on a client with Guillain-Barré syndrome. The nurse determines that which finding would be of most concern? 1.Difficulty articulating words 2.Lung vital capacity of 10 mL/kg 3.Paralysis progressing from the toes to the waist 4.A blood pressure (BP) decrease from 110/78 mm Hg to 102/70 mm Hg - Correct Answer-2 Rationale:Respiratory compromise is a major concern in clients with Guillain-Barré syndrome. Clients often are intubated and mechanically ventilated when the vital capacity is less than 15 mL/kg. Difficulty articulating words and paralysis progressing from the toes to the waist are expected, depending on the degree of paralysis that occurs. Although orthostatic hypotension is a problem with these clients, the BP drop in option 4 is less than 10 mm Hg and is not significant. A client with a traumatic brain injury is able, with eyes closed, to identify a set of keys placed in his or her hands. On the basis of this assessment finding, the nurse determines that there is appropriate function of which lobe of the brain? 1.Frontal 2.Parietal 3.Occipital 4.Temporal - Correct Answer-2 Rationale:The ability to distinguish an object by touch is called stereognosis, which is a function of the right parietal area. The parietal lobe of the brain is responsible for spatial orientation and awareness of sizes and shapes. The left parietal area is responsible for mathematics and right-left orientation. The other lobes of the brain are not responsible for this function. A client has suffered a head injury affecting the occipital lobe of the brain. What is the focus of the nurse's immediate assessment? 1.Taste 2.Smell 3.Vision 4.Hearing - Correct Answer-3 Rationale:The occipital lobe is responsible for reception of vision and contains visual association areas. This area of the brain helps the individual to visually recognize and understand the surroundings. The other senses listed are not a function of the occipital lobe. A client has suffered damage to Broca's area of the brain. Which priority assessment should the nurse perform? 1.Speech 2.Hearing 3.Balance 4.Level of consciousness - Correct Answer-1 Rationale:Broca's area in the brain is responsible for the motor aspects of speech, through coordination of the muscular activity of the tongue, mouth, and larynx. The term assigned to damage in this area is aphasia. The items listed in the other options are not the responsibility of Broca's area. A client has a high level of carbon dioxide (CO2) in the bloodstream, as measured by arterial blood gases. The nurse Barré syndrome are at risk for hypotension or hypertension, bradycardia, and respiratory depression, frequent monitoring of vital signs is required. A client admitted to the nursing unit from the hospital emergency department has a C4 spinal cord injury. In conducting the admission assessment, what is the nurse's priority action? 1.Take the temperature. 2.Listen to breath sounds. 3.Observe for dyskinesias. 4.Assess extremity muscle strength. - Correct Answer-2 Rationale:Because compromise of respiration is a leading cause of death in cervical cord injury, respiratory assessment is the highest priority. Assessment of temperature and strength can be done after adequate oxygenation is ensured. Because dyskinesias occur in cerebellar disorders, this is not as important a concern as in cord-injured clients unless head injury is suspected. The nurse is admitting a client to the hospital emergency department from a nursing home. The client is unconscious with an apparent frontal head injury. A medical diagnosis of epidural hematoma is suspected. Which question is of the highest priority for the emergency department nurse to ask of the transferring nurse at the nursing home? 1."When did the injury occur?" 2."Was the client awake and talking right after the injury?" 3."What medications has the client received since the fall?" 4."What was the client's level of consciousness before the injury?" - Correct Answer-2 Rationale:Epidural hematomas frequently are characterized by a "lucid interval" that lasts for minutes to hours, during which the client is awake and talking. After this lucid interval, signs and symptoms progress rapidly, with potentially catastrophic intracranial pressure increase. Epidural hematomas are medical emergencies. It is important for the nurse to assist in the differentiation between epidural hematoma and other types of head injuries. The nurse has just admitted to the nursing unit a client with a basilar skull fracture who is at risk for increased intracranial pressure (ICP). Pending specific health care provider prescriptions, the nurse should plan to place the client in which positions? Select all that apply. 1.Head midline 2.Neck in neutral position 3.Flat, with head turned to the side 4.Head of bed elevated 30 to 45 degrees 5.Head of bed elevated with the neck extended - Correct Answer-1, 2, 4 Rationale:The client who is at risk for or who has increased ICP should be positioned so that the head is in a neutral, midline position. The nurse should avoid flexing or extending the client's neck or turning the head from side to side. The head of the bed should be raised to 30 to 45 degrees. Use of proper positions promotes venous drainage from the cranium to keep ICP down. The client with a head injury opens eyes to sound, has no verbal response, and localizes to painful stimuli when applied to each extremity. How should the nurse document the Glasgow Coma Scale (GCS) score? 1.GCS = 3 2.GCS = 6 3.GCS = 9 promotes venous drainage from the cranium to keep intracranial pressure down. A postoperative craniotomy client who sustained a severe head injury is admitted to the neurological unit. What nursing intervention is necessary for this client? 1.Take and record vital signs every 4 to 8 hours. 2.Prophylactically hyperventilate during the first 24 hours. 3.Treat a central fever with the administration of antipyretic medications such as acetaminophen. 4.Keep the head of the bed elevated at least 30 degrees, and position the client to avoid extreme flexion or extension of the neck and head. - Correct Answer-4 Rationale:Avoiding extreme flexion and extension of the neck can enhance venous drainage and help prevent increased intracranial pressure. As a general rule, hyperventilation is avoided during the first 24 hours postoperatively because it may produce ischemia caused by cerebral vasoconstriction. Vital signs need to be taken and recorded at least every 1 to 2 hours. Central fevers caused by hypothalamic damage respond better to cooling (hypothermia blankets, sponge baths) than to the administration of antipyretic medications. The nurse is caring for a client with bacterial meningitis. The nurse should anticipate that an antibiotic with which characteristics will be prescribed for the client? 1.One that has a long half-life 2.One that acts within minutes to hours 3.One that can be easily excreted in the urine 4.One that is able to cross the blood-brain barrier - Correct Answer-4 Rationale:A primary consideration regarding medications to treat bacterial meningitis is the ability of the medication to cross the blood-brain barrier. If the medication cannot cross, it will not be effective. The duration, onset, and excretion of the medication are also of general concern but apply to all medications and not specifically to those that are used to treat meningitis. The nurse is planning to perform an assessment of the client's level of consciousness using the Glasgow Coma Scale. Which assessments should the nurse include in order to calculate the score? Select all that apply. 1.Eye opening 2.Reflex response 3.Best verbal response 4.Best motor response 5.Pupil size and reaction - Correct Answer-1, 3, 4 Rationale:Assessment of pupil size and reaction and reflex response are not part of the Glasgow Coma Scale. The 3 categories included are eye opening, best verbal response, and best motor response. Pupil assessment and reflex response is a necessary part of a total assessment of the neurological status of a client but is not part of this particular scale. A client with a traumatic closed head injury shows signs of secondary brain injury. What are some manifestations of secondary brain injury? Select all that apply. 1.Fever 2.Seizures 3.Hypoxia 4.Ischemia 5.Hypotension
