Coronary Artery Disease Quiz
Questions: 16 · 10 minutes
1. A person smokes and has persistently high blood pressure. Which plan most directly addresses both modifiable coronary artery disease risks?
Take a daily vitamin while leaving both habits and blood pressure unchanged
Get support to stop smoking and work with a clinician to manage blood pressure
Avoid physical activity until both risks disappear on their own
Focus only on learning whether coronary artery disease runs in the family
2. A clinician wants to observe symptoms and electrical heart changes while a patient walks on a treadmill. Which test is being described?
A resting blood-pressure measurement
An exercise stress test
A coronary artery calcium blood test
A standard chest X-ray
3. Chest pressure during activity disappears after rest. Which is the best interpretation?
Relief with rest proves that the heart cannot be involved
The pattern may be angina and warrants medical evaluation even though it improves
No medical assessment is useful unless the discomfort causes fainting
Symptoms matter only if they continue for several hours
4. For a person who smokes, which action most directly reduces the coronary risk associated with tobacco?
Switching cigarette brands while smoking the same amount
Exercising only on days when no cigarettes are smoked
Stopping smoking, using evidence-based support when needed
Taking supplements to offset the effects of smoke exposure
5. A patient is told that coronary artery bypass grafting may be needed. What is the procedure intended to do?
Create new routes for blood to travel around significantly narrowed or blocked coronary arteries
Replace the heart's electrical conduction system with an artificial one
Remove all cholesterol from the bloodstream permanently
Prevent the heart muscle from requiring oxygen during activity
6. A person with exertional chest discomfort has a normal resting electrocardiogram (ECG). What can reasonably be concluded?
Coronary artery disease has been completely excluded
The symptoms must come from anxiety rather than the heart
A normal resting ECG confirms that every coronary artery is open
A resting ECG can be normal even when coronary artery disease is present, so further assessment may be needed
7. Which is a nonmodifiable risk factor for coronary artery disease?
Physical inactivity
Cigarette smoking
A diet high in saturated fat
A family history of premature coronary artery disease
8. Someone has sudden chest pressure with sweating, nausea, and discomfort spreading to an arm. What is the most appropriate response?
Wait until the next day to see whether the symptoms return
Drive the person to a routine appointment after the discomfort subsides
Call local emergency services immediately and follow their instructions
Ask the person to exercise briefly to determine whether the pain worsens
9. A person repeatedly develops chest pressure while climbing a hill, and it eases within minutes of resting. What does this pattern most closely resemble?
Heartburn caused specifically by low blood pressure
Stable angina caused by the heart muscle needing more oxygen during exertion
A heart-valve infection that appears only during exercise
An abnormal heart rhythm that can always be identified by the sensation alone
10. Which event most commonly causes a heart attack related to coronary artery disease?
A gradual rise in heart rate without any change in blood flow
A temporary increase in oxygen delivery through an unobstructed artery
A coronary plaque rupturing and triggering a clot that suddenly blocks blood flow
A plaque becoming smaller and widening the artery too quickly
11. Why is diabetes associated with a higher risk of coronary artery disease?
It makes coronary arteries immune to normal blood-pressure changes
It prevents cholesterol from entering the bloodstream
It causes the heart to stop using oxygen during physical activity
Over time, high blood glucose and related changes can damage blood vessels and accelerate atherosclerosis
12. Which process most commonly underlies coronary artery disease?
A temporary spasm in every artery of the body
Excess oxygen causing the coronary arteries to harden
A viral infection that directly dissolves coronary artery tissue
Atherosclerosis, in which fatty and inflammatory material accumulates in artery walls
13. What is coronary artery disease?
Narrowing or blockage of arteries that supply the heart muscle, usually because of plaque buildup
Weakening of the heart's electrical signal caused primarily by aging
Infection of the heart valves by bacteria circulating in the blood
Permanent enlargement of the chambers that receive blood from the lungs
14. How can elevated LDL cholesterol contribute to coronary artery disease?
It can promote cholesterol deposition and plaque formation in artery walls
It prevents inflammatory cells from entering damaged arteries
It dissolves clots before they can affect coronary blood flow
It increases the amount of oxygen carried by each red blood cell
15. What does invasive coronary angiography primarily help clinicians assess?
The amount of oxygen stored inside the lungs
The electrical activity of the brain during chest discomfort
The location and extent of narrowing in the coronary arteries
The strength of the rib cage surrounding the heart
16. What is the primary function of the coronary arteries?
To deliver oxygen-rich blood to the heart muscle
To carry electrical impulses between the heart and brain
To pump blood from the heart to the lungs
To return oxygen-poor blood from the body to the heart
