CERTIFICATION REVIEW, GRADED A+)
# SECTION 1: CARDIOVASCULAR MODULE (Questions 1–35)
**1.** A 62-year-old male with a 40-pack-year smoking history presents
with a blood pressure of 150/90 mmHg in the right arm and 130/80
mmHg in the left arm. What is the most appropriate next step?
A. Repeat the blood pressure measurement in 15 minutes
B. Obtain a CT angiogram of the chest
C. Prescribe amlodipine 5 mg daily
D. Reassure the patient that this is a normal variant
**Correct Answer:** B – Obtain a CT angiogram of the chest
**Rationale:** A significant inter-arm blood pressure difference (>15–
20 mmHg) suggests subclavian artery stenosis, aortic dissection, or
coarctation of the aorta. CT angiogram is indicated to evaluate for
vascular pathology.
**2.** A 55-year-old female presents with dyspnea on exertion, fatigue,
and a systolic murmur best heard at the right upper sternal border that
,2|Page
radiates to the carotids. Which maneuver would increase the intensity of
this murmur?
A. Valsalva maneuver
B. Hand grip
C. Rapid squatting
D. Amyl nitrite inhalation
**Correct Answer:** B – Hand grip
**Rationale:** The murmur described is aortic stenosis. Hand grip
increases afterload and decreases the intensity of hypertrophic
cardiomyopathy murmur but increases the intensity of aortic stenosis
murmur. Valsalva decreases preload and increases hypertrophic
cardiomyopathy murmur.
**3.** A patient with hypertension and type 2 diabetes has a urine
albumin-to-creatinine ratio of 300 mg/g. Which antihypertensive class is
most beneficial for slowing progression of nephropathy?
A. Beta-blocker
B. Thiazide diuretic
C. ACE inhibitor
D. Calcium channel blocker
**Correct Answer:** C – ACE inhibitor
,3|Page
**Rationale:** ACE inhibitors (and ARBs) are preferred in diabetic
nephropathy because they reduce intraglomerular pressure and slow the
progression of albuminuria, independent of blood pressure lowering.
**4.** A 70-year-old male reports lightheadedness when standing up
from a seated position. His lying blood pressure is 140/80 mmHg, and
standing blood pressure is 100/60 mmHg. Which medication is most
likely responsible?
A. Lisinopril
B. Metoprolol
C. Tamsulosin
D. Amlodipine
**Correct Answer:** C – Tamsulosin
**Rationale:** Tamsulosin (alpha-1 blocker) causes vasodilation and
can produce orthostatic hypotension, especially in older adults.
Metoprolol can also cause hypotension, but tamsulosin is a classic cause
in older men with BPH.
**5.** A 48-year-old female presents with palpitations, anxiety, heat
intolerance, and a fine tremor. ECG shows atrial fibrillation with a
ventricular rate of 140 bpm. Which laboratory finding is most likely?
A. Elevated troponin I
B. Low TSH, high free T4
C. Low potassium
, 4|Page
D. High BNP
**Correct Answer:** B – Low TSH, high free T4
**Rationale:** The presentation with atrial fibrillation and
hyperadrenergic symptoms suggests hyperthyroidism. A low TSH and
elevated free T4 confirm thyrotoxicosis as the cause of atrial fibrillation.
**6.** Which heart sound is most consistent with a failing, dilated left
ventricle?
A. S3 gallop
B. S4 gallop
C. Opening snap
D. Ejection click
**Correct Answer:** A – S3 gallop
**Rationale:** An S3 (ventricular gallop) occurs in early diastole and
indicates decreased compliance or volume overload of the left ventricle,
often seen in heart failure with reduced ejection fraction. S4 suggests
stiff, hypertrophied ventricle.
**7.** A patient with known heart failure presents with worsening
dyspnea, jugular venous distention, and +3 pitting edema. Vital signs:
BP 110/70 mmHg, HR 95 bpm. Which medication should be
administered first?
