#1
Which of the following is a common cardiovascular procedure used to open narrowed arteries?
Angioplasty
ExplanationAngioplasty is used to widen narrowed or blocked arteries.
#2
Which of the following imaging techniques uses sound waves to create images of the heart?
Echocardiogram
ExplanationEchocardiogram employs sound waves to produce images of the heart's structure.
#3
Which of the following drugs is commonly used to prevent blood clots during cardiovascular procedures?
Aspirin
ExplanationAspirin is often used to prevent blood clot formation during cardiovascular procedures.
#4
What is the primary purpose of a cardiac catheterization?
To visualize the inside of the coronary arteries
ExplanationCardiac catheterization helps visualize the heart's blood vessels for diagnosis.
#5
What is the primary purpose of a percutaneous transluminal coronary angioplasty (PTCA)?
To open narrowed coronary arteries
ExplanationPTCA is performed to widen narrowed coronary arteries for improved blood flow.
#6
What is the purpose of a coronary artery bypass graft (CABG) surgery?
To create new routes for blood flow to the heart muscle
ExplanationCABG creates new paths for blood to reach the heart muscle, bypassing blocked arteries.
#7
What is the main purpose of an implantable cardioverter-defibrillator (ICD)?
To prevent sudden cardiac arrest
ExplanationICDs monitor heart rhythm and deliver shocks to restore normal rhythm, preventing sudden cardiac arrest.
#8
Which of the following is a potential complication of cardiac catheterization?
Cardiac arrhythmia
ExplanationCardiac arrhythmia, irregular heart rhythm, can be a complication of cardiac catheterization.
#9
What is the primary purpose of a stress test in cardiovascular evaluation?
To assess heart function under physical stress
ExplanationStress tests evaluate how well the heart performs under physical exertion or stress.
#10
Which of the following procedures is used to treat abnormal heart rhythms by delivering controlled electrical shocks to the heart?
Cardioversion
ExplanationCardioversion restores normal heart rhythm by delivering controlled electrical shocks.
#11
Which of the following is NOT a common risk associated with cardiovascular procedures?
Hypotension
ExplanationHypotension, or low blood pressure, is not typically a risk associated with cardiovascular procedures.
#12
What is the primary goal of a transcatheter aortic valve replacement (TAVR) procedure?
To replace a diseased aortic valve without open-heart surgery
ExplanationTAVR replaces a damaged aortic valve using a catheter, avoiding open-heart surgery.
#13
Which of the following imaging techniques involves injecting a radioactive tracer into the bloodstream to visualize blood flow in the heart?
Myocardial perfusion imaging (MPI)
ExplanationMPI uses a radioactive tracer to observe blood flow through the heart.
#14
What is the primary purpose of a left ventricular assist device (LVAD)?
To improve heart function in end-stage heart failure
ExplanationLVAD assists heart function in severe heart failure by helping pump blood.
