#1
Which of the following is a risk factor for cardiovascular diseases?
High blood pressure
ExplanationElevated blood pressure contributes to cardiovascular risk.
#2
Which diagnostic procedure is used to evaluate the electrical activity of the heart?
Electrocardiography
ExplanationElectrocardiography measures the heart's electrical impulses.
#3
What is the leading cause of death globally according to the World Health Organization (WHO)?
Cardiovascular diseases
ExplanationCardiovascular diseases are the primary global cause of mortality.
#4
Which of the following is NOT a type of cardiovascular disease?
Osteoarthritis
ExplanationOsteoarthritis is a joint disorder, not a cardiovascular condition.
#5
Which of the following is a diagnostic test used to evaluate heart function by creating images of the heart's chambers and valves?
Echocardiography
ExplanationEchocardiography creates images of heart structures using sound waves.
#6
What is a common symptom of a stroke, a condition related to cardiovascular health?
Weakness or numbness in the face, arm, or leg
ExplanationStroke symptoms often include weakness or numbness on one side of the body.
#7
What is the term for the buildup of fatty deposits in the arteries, which can lead to cardiovascular diseases?
Atherosclerosis
ExplanationAtherosclerosis involves the accumulation of plaque in arteries.
#8
What is a common symptom of coronary artery disease?
All of the above
ExplanationVarious symptoms including chest pain, shortness of breath, and fatigue may occur.
#9
Which imaging technique uses a radioactive tracer to assess blood flow to the heart muscle?
Positron emission tomography (PET)
ExplanationPET scans utilize radioactive tracers to visualize blood flow.
#10
What is the primary purpose of cardiac catheterization?
To visualize coronary arteries
ExplanationIt is used to view blood flow in coronary arteries via a catheter.
#11
Which of the following is a non-invasive imaging technique used to evaluate blood flow and detect blockages in the coronary arteries?
Nuclear stress test
ExplanationNuclear stress tests help detect coronary artery blockages non-invasively.
#12
Which of the following is a diagnostic procedure that involves injecting dye into the coronary arteries to visualize blood flow?
Coronary angiography
ExplanationAngiography utilizes dye injection to visualize coronary blood flow.
#13
What is the purpose of a Holter monitor in cardiovascular assessment?
To record heart rhythm over a period of time
ExplanationHolter monitors track heart rhythms continuously over a timeframe.
#14
What is the main purpose of a coronary calcium scan?
To detect calcium deposits in coronary arteries
ExplanationIt detects calcium deposits, indicating coronary artery disease risk.
#15
What is the purpose of a stress test in cardiovascular evaluation?
To evaluate heart function under physical stress
ExplanationStress tests assess heart function during exertion.
#16
What is the main purpose of angioplasty in treating coronary artery disease?
To open narrowed or blocked arteries
ExplanationAngioplasty widens narrowed or blocked coronary arteries.
#17
Which of the following is a surgical procedure to bypass blocked arteries and improve blood flow to the heart muscle?
Coronary artery bypass grafting (CABG)
ExplanationCABG bypasses blocked arteries to enhance blood flow to the heart.
#18
What is the primary purpose of a pacemaker?
To deliver electrical impulses to regulate heart rhythm
ExplanationPacemakers regulate heart rhythm by emitting electrical signals.
#19
Which of the following is a surgical procedure used to widen narrowed arteries by inserting a small balloon and inflating it at the site of blockage?
Angioplasty
ExplanationAngioplasty involves using a balloon to widen narrowed arteries.
