1. What is the most common site for arterial catheterization during
cardiac catheterization procedures?
A. Brachial artery
B. Carotid artery
C. Femoral artery
D. Radial artery
The femoral artery is commonly used due to its large size,
accessibility, and direct path to the heart.
2. Which cardiac biomarker is most specific for diagnosing myocardial
infarction?
A. Myoglobin
B. CK-MB
C. Troponin I
D. BNP
Troponin I is highly specific and sensitive for cardiac muscle injury
and remains elevated longer than other markers.
,3. What is the primary purpose of an echocardiogram?
A. Measure blood pressure
B. Assess coronary artery blockages
C. Visualize cardiac structure and function
D. Detect arrhythmias
Echocardiograms use ultrasound to evaluate heart chambers, valves,
and overall function.
4. What does the QRS complex on an ECG represent?
A. Atrial depolarization
B. Ventricular depolarization
C. Ventricular repolarization
D. Atrial repolarization
The QRS complex corresponds to the depolarization of the ventricles,
initiating contraction.
5. What is the normal PR interval range on an ECG?
A. 0.04–0.08 seconds
B. 0.08–0.12 seconds
C. 0.12–0.20 seconds
D. 0.20–0.30 seconds
The normal PR interval is between 0.12 and 0.20 seconds, reflecting
AV node conduction time.
6. Which of the following is a contraindication for exercise stress testing?
A. Acute myocardial infarction
B. Controlled hypertension
C. Stable angina
D. Mild asthma
Recent myocardial infarction is a contraindication due to the risk of
exacerbating ischemia.
, 7. What medication is commonly used to induce pharmacologic stress
during a nuclear stress test?
A. Atropine
B. Adenosine
C. Epinephrine
D. Nitroglycerin
Adenosine is a vasodilator used to simulate exercise-induced stress
by increasing coronary blood flow.
8. Which vein is commonly used for central venous catheterization in
cardiac procedures?
A. Internal jugular vein
B. Femoral artery
C. Subclavian artery
D. Brachial vein
The internal jugular vein provides direct access to the superior vena
cava and right atrium.
9. Which of the following waves is normally upright in most ECG leads?
A. Q wave
B. S wave
C. P wave
D. T wave
The P wave represents atrial depolarization and is typically upright in
leads I, II, and V2-V6.
10. What does ST-segment elevation indicate?
A. Ventricular tachycardia
B. Pulmonary embolism
C. Myocardial infarction
D. Hyperkalemia
