NR511-FINAL EXAM STUDY GUIDE WITH VERIFIED ANSWERS RATED A+ DOWNLOAD TO SCORE A WEEK 1 1) Define diagnostic reasoning Reflective thinking because the process involves questioning one's thinking to determine if all possible avenues have been explored and if the conclusions that are being drawn are based on evidence. Seen as a kind of critical thinking. 2) Discuss and identify subjective data? What the patient tells you, complains of, etc. Chief complaint HPI ROS 3) Discuss and identify objective data? What YOU can see, hear, or feel as part of your exam. Includes lab data, diagnostic test results. Components of HPI 4) Discuss and identify the components of the HPI Specifically related to the chief complaint only. Detailed breakdown of CC. OLDCART 5) What is medical coding? The use of codes to communicate with payers about which procedures were performed and why 6) What is medical billing? Process of submitting and following up on claims made to a payer in order to receive payment for medical services rendered by a healthcare provider. 7) What are CPT codes? Common procedural terminology Offers the official procedural coding rules and guidelines required when reporting medical services and procedures performed by physician and non-physician providers. NR511-FINAL EXAM STUDY GUIDE WITH VERIFIED ANSWERS RATED A+ DOWNLOAD TO SCORE A 8) What are ICD codes? International classification of disease Used to provide payer info on necessity of visit or procedure performed. 9) What is specificity? The ability of the test to correctly detect a specific condition. If a patient has a condition but test is negative, it is a false negative. If a patient does NOT have a condition but the test is positive, it is a false positive. NR511-FINAL EXAM STUDY GUIDE WITH VERIFIED ANSWERS RATED A+ DOWNLOAD TO SCORE A 16)Accurately document why every procedure code must have a corresponding diagnosis code Diagnosis code explains the necessity of the procedure code.

Self-directed learning: an opportunity to investigate more about any topics that you are uncertain of. NR511-FINAL EXAM STUDY GUIDE WITH VERIFIED ANSWERS RATED A+ DOWNLOAD TO SCORE A IBD: chronic immunological dz that manifests in intestinal inflammation. UC and Crohn's are most common. UC: mucosal surface of colon is inflamed, resulting in friability, erosions, bleeding. Usually occurs in rectosigmoid area, but can involve entire colon. Ulcers form in eroded tissue, abscesses form in crypts, become necrotic and ulcerate, mucosa thickens/swells, narrowing lumen. Pt's are at risk for perforation. Symptoms: bleeding, cramping, urge to defecate. Stools are watery diarrhea with blood/mucus. Fecal leuks almost always present in active UC. Tenderness usually in LLQ or across entire abd. Crohn's: inflammation extends deeper into intestinal wall. Can involve all or any layer of bowel wall and any portion of GI tract from mouth to anus. Characteristic segmental presentation of dz'd bowel separated by areas of normal mucosa ("skipped lesions"). With progression, fibrosis thickens bowel wall, narrowing lumen, leading to obstructions, fistulas, ulcerations. Pt's are at greater risk for colorectal cancer. Most common symptoms: cramping, fever, anorexia, wt loss, spasms, flatulance, RLQ pain/mass, bloody/mucus/pus stools. Symptoms increase with stress, after meals. 50% of pt's have perianal involvement (anal/perianal fissures). Inflammation can lead to bleeding, fever, increased WBC, diarrhea, cramping. Abnormalities can be seen on cross-sectional imaging or colonscopy. No single explanation for IBD. Theory: viral, bacterial, or allergic process initially inflames small or large intestine, results in antibody development which chronically attack intestine, leading to inflammation. Possible genetic predisposition. Dx made by H&P correlated with symptoms, must exclude infectious cause for colitis. Primary dx tools: sigmoidoscopy, colonoscopy, barium enema w/small bowel follow- through, CT. NR511-FINAL EXAM STUDY GUIDE WITH VERIFIED ANSWERS RATED A+ DOWNLOAD TO SCORE A Tx is very complex, managed by GI. Drugs: 5-aminosalicylic acid agents have been used for >50yrs, but have shown to be of little value in CD; still used as first attempt for UC. Antidiarrheals w/caution (constipation). Don't use in acute UC or if toxic megacolon. Corticosteroids used when 5-ASA not working. If corticosteroids don't work, use immunomodulators (azathioprine, methotrexate, 6-mercaptopurine), but can cause bone marrow suppression and infection. Newer class: anti-TNF (biologic response modifiers) for mod-severe dz. Remicade (infliximab), Humira (adalimumab), Entyvio (vedolizumab); can increase risk of infection. 4. Discuss two common Inflammatory Bowel Diseases UC and Crohn's are most common. NR511-FINAL EXAM STUDY GUIDE WITH VERIFIED ANSWERS RATED A+ DOWNLOAD TO SCORE A 5.

Terminology Signs: Murphy's: RUQ pain on deep inspiration: seen with inflamed gallbladder. May also be elicited by palpating the RUQ as they take a deep breath. Signs of Peritoneal Irritation: Guarding: voluntary: usually symmetric, muscles more tense on inspiration, usually does hurt to rise from supine to sitting position (using abd muscles), lessens with distraction. NR511-FINAL EXAM STUDY GUIDE WITH VERIFIED ANSWERS RATED A+ DOWNLOAD TO SCORE A involuntary: asymmetrical, rigidity present on inspiration and expiration, rising to sitting position greatly increases pain, doesn't chg with distraction. Rebound Tenderness: McBurney’s point slowly compress abd, then quickly release pressure pain increases. Lab Test for abdominal pain: CBC (to look for infection and blood loss) CMP: (check hydration with BUN, Cr, electrolytes, check LFT's for hepatitis or biliary disease) Amylase/Lipase: (elevated in pancreatitis) UA: (nitrates, leukocytes, RBCs may indicate UTI) Stool for occult blood: (cancer, IBD, diverticulitis, PUD) Pregnancy test of all childbearing age females: (remember this even in young teens) Imaging in Abd Pain: KUB : may detect renal stones, look for stool in colon free air in perforation, dilated loops of bowel in obstruction) Abdominal US: look for gallstones, ovarian cysts or ectopic pregnancy, hydronephrosis due to renal stone, high specificity for appy but not as sensitive as CT. CT: MOST sensitive test for diagnosing acute abd pain. Useful in appy, abscesses, AAA, diverticulitis, SBO, tumors.

Barium enema and flex sigmoidoscopy are contraindicated during the initial stages of an acute attack because of risk of perforation 4. CT scan of the ABD is sometimes needed to r/o abscess formation. 14. Discuss the difference between sensorineural and conductive hearing loss Sensorineural: results from deterioration of cochlea due to loss of hair cells from organ of Corti. Very common in adults. Gradual, progressive, predominantly high-frequency loss with advanced aging (presbycusis). Other causes: ototoxic drugs, loud noises, head trauma, autoimmune dz, metabolic dz, acoustic neuroma. Genetic makeup can influence. Not correctable w/medical or surgical therapies, but can stabilize if loss is gradual. Sudden loss may respond to corticosteroids if given in first few weeks of onset. Dx usually made by audiometry (audiogram) where bone conduction NR511-FINAL EXAM STUDY GUIDE WITH VERIFIED ANSWERS RATED A+ DOWNLOAD TO SCORE A thresholds are measured. Done by audiologist. No proven or recommended treatment/cure. Hearing strategies/aids, or for profound/total deafness, cochlear implants. In Weber test: normal ear hears sounds better. Commonly seen in primary care: tinnitus and Meniere's. In Rinne test: Air conduction is GREATER than bone conduction. NR511-FINAL EXAM STUDY GUIDE WITH VERIFIED ANSWERS RATED A+ DOWNLOAD TO SCORE A Conductive: result of obstruction between middle and outer ear. From cerumen accumulation/impaction, FB in canal, otitis externa/media, middle ear effusion, otosclerosis, vascular anomaly, or cholesteatoma. Tx depends on accurately identified etiology. Most types are reversible. In Weber test: defective ear hears tuning fork louder. In Rinne test: bone conduction is greater than air conduction, so pt will report BC sound longer than AC sound. 15.
