Q1 QUESTION 1 OF 25
Page 1
, Which finding on cardiac catheterization is MOST consistent with mitral regurgitation?
CORRECT ANSWER
Elevated left atrial pressure and abnormal regurgitant flow
RATIONALE
Mitral regurgitation causes blood to flow backward into the left atrium during systole, leading to elevated left atrial
pressure and demonstrable regurgitant flow on angiography. The key concept tested is the hemodynamic
consequence of mitral valve insufficiency.
Q2 QUESTION 2 OF 25
A 72-year-old male with a history of hypertension and type 2 diabetes presents to the clinic for follow-up. He
has recently been diagnosed with paroxysmal atrial fibrillation. Which is the MOST appropriate initial step in
determining his risk for thromboembolic complications?
CORRECT ANSWER
Calculate the CHA DS -VASc score to guide anticoagulation decisions
RATIONALE
Calculating the CHA DS -VASc score is the initial step to stratify stroke risk in patients with atrial fibrillation, guiding
the decision for anticoagulation therapy. This score quantifies the risk of thromboembolic events based on clinical
factors.
Q3 QUESTION 3 OF 25
Which electrocardiogram (ECG) finding is MOST associated with aortic stenosis?
CORRECT ANSWER
Prominent R waves in V5/V6 and deep S waves in V1/V2
RATIONALE
Aortic stenosis leads to left ventricular hypertrophy, which increases the voltage of the QRS complex, manifesting as
prominent R waves in precordial leads V5/V6 and deep S waves in V1/V2 due to altered electrical vector. This finding
reflects the compensatory thickening of the ventricular wall under increased afterload.
