QUESTIONS AND CORRECT DETAILED ANSWERS
(VERIFIED ANSWERS) ALREADY GRADED A+ (MOST
RECENT!!)
1. Which vessel is most commonly used for arterial access in
cardiac interventional procedures?
A) Brachial artery
B) Radial artery
C) Femoral artery
D) Popliteal artery
Correct Answer: C
Rationale: The femoral artery is the most common access site due
to its large caliber, superficial location, and ease of use for
catheter-based cardiac interventions . The radial artery is
increasingly popular but remains second in overall frequency.
2. What is the primary purpose of balloon angioplasty in
coronary intervention?
A) Remove plaque
B) Dissolve thrombus
C) Compress plaque against the vessel wall
1
,D) Replace a stenotic valve
Correct Answer: C
Rationale: Balloon angioplasty compresses atherosclerotic
plaque against the vessel wall to widen the lumen and restore
blood flow. It does not remove or dissolve plaque .
3. Which medication is commonly used to prevent clot
formation during cardiac catheterization?
A) Aspirin
B) Warfarin
C) Clopidogrel
D) Heparin
Correct Answer: D
Rationale: Heparin is the standard anticoagulant used during
cardiac catheterization to prevent thrombus formation on
catheters and guidewires . Its effect is monitored using Activated
Clotting Time (ACT) .
4. The primary imaging modality used in cardiac
interventional radiography is:
A) Ultrasound
B) Computed Tomography (CT)
C) Magnetic Resonance Imaging (MRI)
2
,D) Fluoroscopy
Correct Answer: D
Rationale: Fluoroscopy provides real-time X-ray imaging
essential for guiding catheters, wires, and devices through the
cardiovascular system .
5. What is the main function of a coronary stent?
A) Dissolve plaque
B) Keep the vessel open
C) Measure intracoronary pressure
D) Stop bleeding from the access site
Correct Answer: B
Rationale: A stent acts as a permanent scaffold to maintain
vessel patency after angioplasty, preventing acute closure and
restenosis .
6. Which type of contrast media is most commonly used in
cardiac catheterization?
A) Barium sulfate
B) Gadolinium-based
C) Iodinated contrast
D) Carbon dioxide
Correct Answer: C
3
, Rationale: Iodinated contrast (ionic and non-ionic) is
water-soluble and radiopaque, making it ideal for visualization
of blood vessels. Non-ionic low-osmolar agents are preferred to
reduce patient reactions .
7. For a patient with an eGFR of 42 mL/min/1.73m²
undergoing elective PCI, the CI technologist should anticipate:
A) No special precautions
B) Use of iso-osmolar contrast media with pre-procedure
hydration
C) Immediate cancellation of the procedure
D) Administration of N-acetylcysteine only
Correct Answer: B
Rationale: For eGFR <60, ACC/AHA guidelines recommend
iso-osmolar or low-osmolar contrast, IV hydration, and
minimization of contrast volume to reduce the risk of
contrast-induced nephropathy (CIN) . The use of N-acetylcysteine
is not consistently supported by evidence.
8. During coronary angiography, which projection best
visualizes the left anterior descending (LAD) artery?
A) Right anterior oblique (RAO) with caudal angulation
B) Left anterior oblique (LAO) with cranial angulation
