Exam Questions and Answers
Question 1: What is the primary mechanism of action for beta-blockers in treating
hypertension?
A) Increase cardiac output
B) Decrease heart rate and myocardial contractility
C) Dilate peripheral blood vessels
D) Inhibit sodium reabsorption
Rationale: Beta-blockers reduce blood pressure by decreasing heart rate and contractility,
reducing cardiac output.
Question 2: A patient with type 2 diabetes is prescribed metformin. What is a key patient
education point?
A) Take with grapefruit juice
B) Take with food to reduce GI upset
C) Avoid all carbohydrates
D) Monitor blood pressure daily
Question 3: Which diagnostic test is most specific for confirming acute myocardial
infarction?
, A) ECG
B) Troponin levels
C) Chest X-ray
D) Complete blood count
Rationale: Troponin is a highly specific biomarker for myocardial injury.
Question 4: A patient presents with cough, fever, and crackles in the lower lobes. What is the
most likely diagnosis?
A) Asthma
B) Pneumonia
C) Heart failure
D) COPD
Question 5: What is the first-line treatment for mild persistent asthma in an adult?
A) High-dose inhaled corticosteroid
B) Low-dose inhaled corticosteroid
C) Oral prednisone
D) Theophylline
Question 6: A 65-year-old patient is prescribed warfarin. What is a key monitoring
parameter?
A) Blood glucose
B) International Normalized Ratio (INR)
C) Serum creatinine
D) Platelet count
Rationale: INR monitors warfarin's anticoagulant effect to ensure therapeutic levels.
Question 7: What pathophysiologic process underlies diabetic ketoacidosis (DKA)?
A) Excess insulin production
B) Insulin deficiency and hyperglycemia
C) Hypoglycemia
D) Chronic renal failure
Question 8: A patient with suspected appendicitis presents with right lower quadrant pain.
What is a key physical exam finding?
A) Murphy’s sign
B) Rovsing’s sign
C) Psoas sign
D) Cullen’s sign
Question 9: What is a primary goal of chronic disease management in hypertension?
A) Increase blood pressure
B) Prevent end-organ damage
C) Reduce physical activity
D) Limit fluid intake
Question 10: A patient is prescribed a thiazide diuretic. What electrolyte should be
monitored?
A) Calcium
B) Potassium
