Abstract:
This document provides a rigorous preparation tool for the NR576 Differential Diagnosis in Adult-Gerontology
Primary Care midterm examination. It comprises 200 carefully selected questions that span the core content areas
of the course: cardiovascular, respiratory, gastrointestinal, genitourinary, musculoskeletal, and neurological
systems, as well as endocrine, dermatologic, and psychiatric conditions common in older adults. Each question is
designed to test the student's ability to synthesize patient history, physical examination findings, and diagnostic test
results to formulate accurate differential diagnoses. The answers are accompanied by detailed rationales that
explain the clinical reasoning process and highlight key distinctions between similar presentations. Emphasis is
placed on evidence-based guidelines from sources such as the American Heart Association, American Diabetes
Association, and the Gerontological Society of America. This resource is intended to be used as a comprehensive
review supplement, reinforcing concepts taught throughout the semester and simulating the complexity of
real-world clinical decision-making in primary care settings serving adult and geriatric populations.

,Q1. A 52-year-old with hypertension and diabetes reports acute onset of pleuritic
chest pain, dyspnea, and hemoptysis. ECG shows sinus tachycardia with S1Q3T3
pattern. D-dimer is elevated. Which diagnostic finding best confirms the suspected
diagnosis?
A. Lobar consolidation on chest X-ray
B. Filling defect on CT pulmonary angiography
C. Positive blood culture for Staphylococcus aureus
D. Elevated troponin I with dynamic changes
Correct Answer: B. Filling defect on CT pulmonary angiography
Rationale: CT pulmonary angiography is the gold standard for diagnosing pulmonary
embolism (PE). The clinical presentation (pleuritic pain, dyspnea, hemoptysis) plus ECG
findings and elevated D-dimer strongly suggest PE. Option B confirms acute PE. Option A
suggests pneumonia without embolus; C suggests endocarditis or sepsis; D suggests
myocardial infarction.
Why Wrong:
A - Lobar consolidation indicates pneumonia, not a thrombotic embolus.
C - Positive blood culture suggests infective endocarditis or bacteremia, not PE.
D - Elevated troponin with dynamic changes is typical of acute coronary syndrome,
not PE.

Journal of Medicine, 374(15), 1449-1458.
Q2. A 47-year-old presents with progressive dysphagia to solids, 'pins and needles'
sensation in both feet, and a tongue that appears smooth and red. CBC shows
macrocytic anemia. Which of the following diagnostic findings is most specific for the
underlying cause?
A. Positive anti-tissue transglutaminase IgA antibodies
B. Low serum vitamin B12 and elevated methylmalonic acid
C. Positive anti-parietal cell antibodies
D. Elevated serum gastrin level
Correct Answer: C. Positive anti-parietal cell antibodies
Rationale: The presentation suggests pernicious anemia: macrocytic anemia, glossitis,
neuropathy, and dysphagia (due to Plummer-Vinson syndrome). Anti-parietal cell
antibodies are highly sensitive and specific for autoimmune atrophic gastritis causing
pernicious anemia. Option A indicates celiac disease; B confirms B12 deficiency but not
the cause; D can be seen in gastrinoma.
Why Wrong:
A - Anti-tissue transglutaminase IgA is specific for celiac disease, not pernicious
anemia.
Page 3
, B - Low B12 and elevated MMA confirm deficiency but do not identify the etiology.
D - Elevated gastrin is found in Zollinger-Ellison syndrome, not pernicious anemia.

Q3. A 60-year-old with chronic kidney disease (GFR 25 mL/min) and type 2 diabetes
presents with acute-onset, severe, constant burning epigastric pain radiating to the
back. Serum lipase is 1,200 U/L. Which of the following is the most appropriate next
step in management?
A. Emergent endoscopic retrograde cholangiopancreatography (ERCP)
B. Aggressive intravenous fluid resuscitation with normal saline
C. Computed tomography of the abdomen with intravenous contrast
D. Administration of intravenous pantoprazole and repeat lipase in 6 hours
Correct Answer: B. Aggressive intravenous fluid resuscitation with normal saline
Rationale: The patient has acute pancreatitis (epigastric pain, back radiation, elevated
lipase). In CKD, contrast nephropathy risk is high; thus, CT with contrast is relatively
contraindicated. Fluid resuscitation remains the cornerstone of early management to
prevent hypovolemia and pancreatic necrosis. ERCP is indicated only if biliary
obstruction is suspected (e.g., cholangitis). Pantoprazole alone is insufficient.
Why Wrong:
A - ERCP is not urgently indicated without evidence of cholangitis or biliary
obstruction.
C - IV contrast is relatively contraindicated in advanced CKD (GFR <30).
D - Pantoprazole and rechecking lipase would delay necessary fluid resuscitation.

management of acute pancreatitis. American Journal of Gastroenterology,
121(5), 700-725.
Q4. A 55-year-old with no known cardiovascular disease presents with several
episodes of transient loss of consciousness lasting 1-2 minutes, each associated with
palpitations. ECG shows sinus rhythm with a PR interval of 0.28 seconds and a QRS
duration of 0.12 seconds. Which of the following is the most likely diagnosis?
A. Vasovagal syncope
B. Complete heart block
C. First-degree AV block with bifascicular block
D. Sick sinus syndrome
Correct Answer: C. First-degree AV block with bifascicular block
Rationale: The prolonged PR interval (first-degree AV block) and wide QRS (0.12 s)
indicate bifascicular block (right bundle branch block with left anterior fascicular block or
