ANSWERS FOR GUARANTEED PASS | NEWEST UPDATE,
Question 1
When performing an intervention in the mid-to-distal right leg from a left radial approach,
which guidewire length would be the most appropriate choice?
A) 0.035 in x 180 cm
B) 0.038 in x 180 cm
C) 0.035 in x 260 cm
D) 0.038 in x 150 cm
Correct Answer: C) 0.035 in x 260 cm
Rationale: The distance from the radial artery to the distal leg requires an extra-long
guidewire. A 260 cm wire is necessary to traverse this distance and still have enough external
wire length to exchange devices.
Question 2
Which term BEST describes a balloon's ability to yield and increase in diameter with changes in
inflation pressure?
A) Flexibility
B) Pushability
C) Trackability
D) Compliance
Correct Answer: D) Compliance
Rationale: Compliance refers to the balloon's distensibility. A high-compliance balloon will
continue to grow in diameter as pressure increases, while a non-compliant balloon will
maintain its stated diameter.
Question 3
What is the PRIMARY therapeutic reason for using rotational atherectomy during a PCI?
A) To score fibrotic plaque.
B) To ablate and modify calcific atherosclerotic plaque.
C) To pulverize plaque using electromagnetic energy.
,D) To remove thrombus using the Venturi effect.
Correct Answer: B) To ablate and modify calcific atherosclerotic plaque.
Rationale: Rotational atherectomy (Rotablator) uses a diamond-tipped burr to ablate heavily
calcified plaque, modifying the lesion to allow for proper stent expansion.
Question 4
A Fogarty balloon catheter is a specialized device commonly used to:
A) Dilate a stenotic lesion.
B) Push plaque distally.
C) Perform an embolectomy by pulling thrombus out of a vessel.
D) Measure right heart pressures.
Correct Answer: C) Perform an embolectomy by pulling thrombus out of a vessel.
Rationale: The Fogarty catheter is passed beyond a clot, inflated, and then withdrawn, pulling
the thrombus out with it.
Question 5
Which of the following methods are used to treat a flow-limiting coronary artery dissection?
(Select three)
A) Stent
B) Angioplasty
C) Atherectomy
D) Covered stent
E) Thrombectomy
Correct Answer: A, B, D) Stent, Angioplasty, Covered stent
Rationale: A flow-limiting dissection can be treated by tacking up the dissection flap with a
stent. A covered stent may be used for a perforation. Low-pressure balloon angioplasty may
also be used to gently appose the flap.
Question 6
When performing rotational atherectomy in the Right Coronary Artery (RCA), which adjunctive
therapies should be considered? (Select three)
,A) Stiff guidewire
B) Vasodilator drug (e.g., nitroglycerin, nicardipine)
C) Guide catheter with side holes
D) Temporary pacing wire
E) A large-sized burr
Correct Answer: B, D, E) Vasodilator drug (e.g., nitroglycerin, nicardipine), Temporary pacing
wire, A large-sized burr
Rationale: Rotational atherectomy in the dominant RCA carries a high risk of bradycardia and
transient heart block due to ischemia or micro-embolization to the AV nodal artery. A
temporary pacemaker is often placed as a precaution. Vasodilators help prevent no-reflow.
The provided answer key states "large size burr" which is unusual, but following the key.
Question 7
Prior to prepping a patient for a cardiac catheterization procedure, which four pieces of
information are required?
A) NPO status
B) Patient allergies
C) Patient identifiers
D) Advance directives
E) Last H&P was 40 days ago
F) Last visit to primary physician
Correct Answer: A, B, C, D) NPO status, Patient allergies, Patient identifiers, Advance
directives
Rationale: These are all critical pre-procedure checks. Patient ID is a universal safety protocol.
Allergy status is vital for contrast and medication safety. NPO status is required to prevent
aspiration. Advance directives are important in case of a life-threatening complication.
Question 8
Which of the following inotropic agents predominantly stimulates beta-1 adrenergic receptors
to increase contractility and heart rate?
A) Isuprel (isoproterenol)
, B) Dopamine
C) Dobutamine
D) Epinephrine
Correct Answer: C) Dobutamine
Rationale: Dobutamine is a synthetic catecholamine that primarily acts on beta-1 receptors to
increase myocardial contractility (inotropic effect) with minimal effects on heart rate and
peripheral vasculature.
Question 9
What is the primary desired hemodynamic effect of intra-aortic balloon pump (IABP)
counterpulsation?
A) Increased preload
B) Increased afterload
C) Increased coronary blood flow
D) Increased myocardial oxygen demand
Correct Answer: C) Increased coronary blood flow
Rationale: The IABP inflates during diastole, which increases diastolic pressure (diastolic
augmentation). This increased pressure in the aortic root improves perfusion to the coronary
arteries.
Question 10
Which two actions are required when prepping a patient for a transradial cardiac
catheterization?
A) Prep the right groin as a backup site.
B) Perform an Allen's test prior to wrist prep.
C) Position the wrist in a prone position.
D) Start the IV on the same arm as the radial access site.
Correct Answer: A, B) Prep the right groin as a backup site; Perform an Allen's test prior to
wrist prep.
Rationale: An Allen's test (or a modified version like the Barbeau test) is essential to confirm
