Introduction
The AACN VAD Competency Practice Exam is designed to assess the knowledge and clinical
reasoning skills required for the proficient management of patients with ventricular assist devices.
This comprehensive assessment evaluates foundational device theory, applied professional
knowledge, technical concepts, regulatory compliance, and ethical standards. Candidates will
encounter multiple-choice and scenario-based items that emphasize real-world application,
critical thinking, and professional decision-making. Successful completion indicates readiness to
provide safe, evidence-based care to the VAD patient population.
SECTION ONE – QUESTIONS 1–100
Question 1
The primary purpose of a ventricular assist device (VAD) is to:
A. permanently replace the native heart
B. support circulation in patients with advanced heart failure
,C. correct valvular abnormalities
D. treat acute myocardial infarction
🟢 B. support circulation in patients with advanced heart failure
🔴 Explanation: VADs are mechanical circulatory support devices used to assist ventricular
function in patients with advanced heart failure, either as a bridge to transplant, bridge to
recovery, or destination therapy. They do not replace the heart or directly treat valvular disease
or myocardial infarction.
Question 2
Which chamber is most commonly supported by contemporary VADs?
A. Right ventricle
B. Left ventricle
C. Both atria
D. Both ventricles simultaneously
🟢 B. Left ventricle
🔴 Explanation: Most implanted VADs are left ventricular assist devices (LVADs) because left
ventricular failure is more common and has a greater impact on systemic perfusion. RVADs and
BiVADs are used less frequently.
Question 3
Continuous-flow LVADs differ from pulsatile devices primarily because they:
A. generate a palpable pulse
B. use diaphragms and valves
C. provide constant blood flow
D. require no anticoagulation
🟢 C. provide constant blood flow
🔴 Explanation: Continuous-flow LVADs deliver a constant stream of blood rather than
pulsatile ejections. This design is smaller, more durable, and has fewer mechanical failures than
,first-generation pulsatile devices.
Question 4
Which parameter best reflects LVAD pump flow?
A. Heart rate
B. Pump speed
C. Pump flow
D. Systemic vascular resistance
🟢 C. Pump flow
🔴 Explanation: Pump flow is an estimated value derived from speed and power and reflects
the volume of blood moving through the device. While speed influences flow, the flow reading
itself is the direct indicator of device output.
Question 5
A sudden drop in LVAD flow with increased pump power most likely indicates:
A. hypovolemia
B. suction event
C. pump thrombosis
D. right ventricular failure
🟢 C. pump thrombosis
🔴 Explanation: Pump thrombosis increases resistance within the pump, leading to higher
power consumption and reduced effective flow. Hypovolemia and suction events typically
produce low flow with low or normal power.
Question 6
Which anticoagulation strategy is most commonly required for LVAD patients?
A. No anticoagulation
B. Aspirin only
, C. Warfarin with antiplatelet therapy
D. Direct oral anticoagulant alone
🟢 C. Warfarin with antiplatelet therapy
🔴 Explanation: LVAD patients typically require warfarin plus antiplatelet therapy to reduce the
risk of pump thrombosis and thromboembolic events. Direct oral anticoagulants are not
standard for LVAD management.
Question 7
A key nursing priority when caring for a patient with an LVAD driveline is to:
A. flush the driveline daily
B. keep the site dry and immobilized
C. apply pressure dressings
D. remove the driveline weekly
🟢 B. keep the site dry and immobilized
🔴 Explanation: Driveline infections are a major complication; meticulous sterile care,
stabilization, and keeping the site dry are essential. Flushing the driveline or applying pressure
dressings is not appropriate.
Question 8
Which complication is most strongly associated with long-term LVAD support?
A. Hypoglycemia
B. Gastrointestinal bleeding
C. Hyperkalemia
D. Bradycardia
🟢 B. Gastrointestinal bleeding
🔴 Explanation: Gastrointestinal bleeding is strongly associated with continuous-flow LVADs
due to acquired von Willebrand factor deficiency and angiodysplasia formation from reduced
pulsatility.
