Question 1
A 68-year-old male with a history of hypertension and diabetes presents with new-
onset exertional dyspnea and bilateral lower extremity edema. Which finding most
strongly supports a diagnosis of heart failure with reduced ejection fraction
(HfrEF)?
A. S3 heart sound
B. Loud S2
C. Widened pulse pressure
D. Bounding peripheral pulses
Correct Answer: A
Rationale: An S3 gallop is associated with volume overload and decreased
ventricular compliance, commonly seen in HfrEF.
Question 2
A patient with chronic kidney disease stage 3 is prescribed an ACE inhibitor.
Which laboratory value requires the most immediate follow-up?
,A. Potassium 5.6 mEq/L
B. Sodium 134 mEq/L
C. Calcium 8.7 mg/dL
D. Hemoglobin 11.8 g/dL
Correct Answer: A
Rationale: ACE inhibitors can increase potassium levels; hyperkalemia poses a risk
for life-threatening arrhythmias.
Question 3
A 45-year-old female presents with fatigue, weight gain, cold intolerance, and
constipation. Which laboratory pattern is most consistent with the suspected
diagnosis?
A. Low TSH, high T4
B. High TSH, low T4
C. Normal TSH, high T3
D. Low cortisol, high ACTH
Correct Answer: B
Rationale: Primary hypothyroidism presents with decreased thyroid hormone and
compensatory elevation in TSH.
Question 4
,Which medication is most appropriate as first-line therapy for newly diagnosed
type 2 diabetes mellitus in a patient without contraindications?
A. Insulin glargine
B. Metformin
C. Glyburide
D. Pioglitazone
Correct Answer: B
Rationale: Metformin improves insulin sensitivity, promotes modest weight loss,
and has cardiovascular benefits.
Question 5
A patient presents with crushing substernal chest pain radiating to the left arm.
ECG shows ST-segment elevation in leads II, III, and aVF. Which artery is most
likely occluded?
A. Left anterior descending
B. Left circumflex
C. Right coronary artery
D. Posterior descending artery
Correct Answer: C
Rationale: Inferior wall myocardial infarctions are commonly caused by right
coronary artery occlusion.
, Question 6
Which clinical finding differentiates asthma from chronic obstructive pulmonary
disease (COPD)?
A. Wheezing
B. Reversible airflow obstruction
C. Hyperinflation on chest X-ray
D. Dyspnea on exertion
Correct Answer: B
Rationale: Asthma is characterized by reversible airflow limitation, unlike COPD
which is largely irreversible.
Question 7
A patient taking warfarin presents with an INR of 5.8 and no signs of bleeding.
What is the most appropriate management?
A. Administer vitamin K IV
B. Hold warfarin and monitor INR
C. Transfuse fresh frozen plasma
D. Continue current dose
Correct Answer: B
