1. The normal range for adult resting heart rate is:
A. 30–50 bpm
B. 50–60 bpm
C. 60–100 bpm
D. 100–120 bpm
Rationale: Normal adult resting heart rate is typically 60–
100 beats per minute.
2. Which vessel is primarily assessed when performing a
carotid duplex for stroke risk?
A. External carotid artery
B. Vertebral artery
C. Internal carotid artery
D. Facial artery
Rationale: The internal carotid artery is the main vessel
evaluated for atherosclerotic stenosis related to stroke.
,3. A continuous wave Doppler is best used to measure:
A. Low-velocity flow only
B. Very high velocity flow without aliasing
C. Flow direction only
D. Wall motion
Rationale: CW Doppler measures high velocities without
aliasing but lacks range resolution.
4. Which acoustic window is typically used for apical four-
chamber TTE imaging?
A. Subcostal
B. Parasternal long axis
C. Apical
D. Suprasternal notch
Rationale: The apical window provides the four-chamber
view for TTE.
5. The ejection fraction is a measurement of:
A. Right ventricular size
B. Left ventricular systolic function
C. Diastolic filling pressure
D. Pulmonary artery pressure
Rationale: Ejection fraction quantifies LV systolic function
as percent blood ejected per beat.
6. In vascular ultrasound, spectral broadening usually
indicates:
, A. Laminar flow
B. Turbulent or disturbed flow
C. No flow
D. Stationary tissue
Rationale: Spectral broadening occurs with
disturbed/turbulent flow increasing range of velocities.
7. During cardiac cath, anticoagulant most commonly used to
reduce thrombosis risk is:
A. Warfarin
B. Aspirin only
C. Heparin
D. tPA
Rationale: Unfractionated heparin is commonly used
intra-procedurally to prevent clot formation.
8. The QRS complex on ECG corresponds to:
A. Atrial depolarization
B. ST segment
C. Ventricular depolarization
D. Ventricular repolarization
Rationale: The QRS represents ventricular depolarization
leading to ventricular contraction.
9. For duplex imaging of peripheral arteries, which
transducer frequency is most appropriate for a deep calf
vessel in an obese patient?
, A. 10–15 MHz
B. 7–12 MHz
C. 3–5 MHz
D. 15–20 MHz
Rationale: Lower frequency (3–5 MHz) provides greater
penetration for deep vessels in obese patients.
10. Which of the following is a contraindication to stress
echocardiography?
A. Controlled hypertension
B. Acute myocardial infarction within 48 hours
C. Stable angina
D. Exercise intolerance
Rationale: Recent acute MI is a contraindication due to
risk of provoking complications.
11. The ankle–brachial index (ABI) is calculated by
dividing:
A. Brachial systolic by ankle systolic
B. Ankle systolic by brachial systolic
C. Ankle diastolic by brachial diastolic
D. Ankle systolic by ankle diastolic
Rationale: ABI = highest ankle systolic pressure / highest
brachial systolic pressure.
12. A normal pulmonary artery systolic pressure
estimated by echo is approximately:
