Questions and Correct
Answers with Rationale 2026
Question 1 – Advanced Assessment
A 58-year-old man presents with crushing substernal chest pain
radiating to his left arm that began 30 minutes ago. He is
diaphoretic and nauseated.
Which finding is most concerning?
A. Heart rate 88 bpm
B. Blood pressure 152/88 mmHg
C. ST-segment elevation in leads II, III, and aVF
D. Respiratory rate 20/min
Answer
✅ C. ST-segment elevation in leads II, III, and aVF
Rationale
,ST-segment elevation in the inferior leads indicates an acute ST-
elevation myocardial infarction (STEMI), requiring immediate
reperfusion therapy.
Question 2 – Pathophysiology
Which mechanism is primarily responsible for edema in
congestive heart failure?
A. Increased plasma proteins
B. Increased hydrostatic pressure
C. Increased oncotic pressure
D. Increased lymphatic drainage
Answer
✅ B. Increased hydrostatic pressure
Rationale
Reduced cardiac output causes blood to back up in the venous
system, increasing capillary hydrostatic pressure and pushing
fluid into the tissues.
Question 3 – Pharmacology
,A patient with hypertension and diabetes has newly diagnosed
microalbuminuria.
Which medication is preferred?
A. Hydrochlorothiazide
B. Metoprolol
C. Lisinopril
D. Amlodipine
Answer
✅ C. Lisinopril
Rationale
ACE inhibitors reduce intraglomerular pressure, slow diabetic
nephropathy progression, and provide renal protection.
Question 4 – Assessment
During cardiac auscultation, an S3 heart sound is heard in a 72-
year-old patient with dyspnea.
What does this finding most likely indicate?
A. Normal aging
B. Left ventricular volume overload
, C. Pericarditis
D. Aortic stenosis
Answer
✅ B. Left ventricular volume overload
Rationale
An S3 in older adults is usually abnormal and is commonly
associated with heart failure and volume overload.
Question 5 – Pathophysiology
Which laboratory value is most specific for acute myocardial
injury?
A. CK-MB
B. Myoglobin
C. Troponin I
D. LDH
Answer
✅ C. Troponin I
Rationale
