What is the exam format for NR511 Final Exam?
Correct Answer: Noncumulative, consisting of 100 multiple choice questions (covers GI, GU, male
reproductive, upper/lower extremity disorders, neck/back disorders, bites, lacerations).
1. The final exam focuses only on content from Weeks 5-8 (not cumulative with midterm material). Same
format as midterm: 100 questions in 120 minutes.
2. Available from Wednesday Week 8 at 12:01 am MT until Saturday Week 8 at 11:59 pm MT.
What is a differential diagnosis for irritable bowel syndrome (IBS)?
Correct Answer: Inflammatory bowel disease (Crohn's, ulcerative colitis), celiac disease,
gastrointestinal infections (post-infectious IBS), microscopic colitis, lactose intolerance, colorectal
cancer (alarm features).
1. IBS is diagnosed by Rome IV criteria (recurrent abdominal pain at least 1 day/week in last 3 months,
associated with defecation, change in stool frequency or form).
2. Alarm features (weight loss, nocturnal symptoms, rectal bleeding, family history of IBD/colorectal
cancer, age >50) warrant colonoscopy to rule out organic disease.
What is GERD?
Correct Answer: Gastroesophageal reflux disease (GERD) is a chronic digestive condition where
stomach acid or bile irritates the food pipe lining (esophagus), causing symptoms ≥2 times/week or
mucosal damage.
1. Typical symptoms: heartburn (retrosternal burning), regurgitation, dysphagia, chest pain (non-cardiac).
Atypical: chronic cough, hoarseness, laryngitis, asthma, dental erosion.
2. Diagnosis: clinical (typical symptoms no alarm signs) or endoscopy with biopsy for GERD
complications (Barrett's esophagus, erosive esophagitis).
3. Treatment: lifestyle modifications (weight loss, head of bed elevation, avoid triggers), PPIs (first-line),
H2 blockers.
, How is Crohn's disease managed?
Correct Answer: Management of Crohn's disease may include medication (aminosalicylates,
corticosteroids, immunomodulators, biologics), dietary changes (low residue, enteral nutrition), and
sometimes surgery (resection, strictureplasty).
1. Crohn's disease: transmural inflammation, skip lesions, can affect entire GI tract (terminal ileum most
common). Fistulas, strictures, abscesses common.
2. Induction of remission: corticosteroids (budesonide or prednisone) or biologics (anti-TNF: infliximab,
adalimumab). Maintenance: immunomodulators (azathioprine, methotrexate) or biologics.
3. Monitoring: periodic colonoscopy for dysplasia surveillance. Smoking cessation is critical (worsens
disease).
What is the role of rotavirus in diarrhea?
Correct Answer: Rotavirus is a leading cause of severe diarrhea in young children (mostly <5 years),
leading to dehydration and hospitalization (watery, non-bloody diarrhea, vomiting, fever).
1. Rotavirus is highly contagious. Vaccination (RV1, RV5) greatly reduced disease burden. Anticipatory
guidance: oral rehydration solution prevents dehydration.
2. Treatment is supportive (no antiviral). Prevent transmission with hand hygiene.
What are the physical assessment findings for pyelonephritis?
Correct Answer: Flank pain (costovertebral angle tenderness), fever (>38°C/100.4°F), dysuria,
frequency, urgency, nausea/vomiting, chills, tachycardia.
1. Pyelonephritis is upper UTI (kidney infection). Diagnosis: urinalysis (WBC, nitrites, leukocyte
esterase), urine culture, CBC (leukocytosis). Imaging (CT or ultrasound) if no response to antibiotics or
recurrent.
2. Treatment: outpatient oral fluoroquinolones (ciprofloxacin, levofloxacin) or ceftriaxone IV + oral step-
down. Hospitalization for sepsis, unable to tolerate oral, pregnancy, or significant comorbidities.
What is the etiology of urethritis in young adult males?
Correct Answer: Urethritis in young adult males is often caused by sexually transmitted infections
such as Neisseria gonorrhoeae (gonococcal urethritis) or Chlamydia trachomatis (nongonococcal
urethritis).
1. Symptoms: dysuria, urethral discharge (mucoid, purulent, or clear), urethral pruritus. Asymptomatic
infection common.
2. Diagnosis: urethral swab or first void urine for NAAT (chlamydia/gonorrhea). Gram stain: >5 WBC per
oil immersion field.
3. Treatment: ceftriaxone 500 mg IM (gonorrhea) + doxycycline 100 mg BID x7 days (chlamydia). Treat
sexual partners.
What are the symptoms of acute lymphoblastic leukemia (ALL)?
Correct Answer: Fatigue, fever, easy bruising or bleeding, frequent infections, bone pain,
lymphadenopathy, hepatosplenomegaly (due to bone marrow failure and extramedullary infiltration).
1. ALL is most common childhood leukemia (peaks 2-5 years). Emergent CBC shows pancytopenia,
blasts in peripheral blood.
2. Diagnosis: bone marrow aspiration (≥20% lymphoblasts). Refer urgently to pediatric oncology;
treatment with multi-agent chemotherapy.
3. Avoid NSAIDs for bone pain (bleeding risk in thrombocytopenia).
