Read each stem, choose your answer, then check the rationale directly below it. The correct
option is marked, and each wrong option is explained so you understand why it's wrong — not
just that it is.

1 The nurse is teaching a client about coronary artery disease (CAD). Which statement
best describes CAD?
A Narrowing of the heart vessels
B Dilation of the heart vessels
C Thickening of the heart muscle
D Weakening of the heart valves
Correct Answer: A Coronary artery disease (CAD) is characterized by narrowing of the heart
vessels due to atherosclerosis, which reduces blood flow to the myocardium.
B — Dilation of vessels is not CAD; CAD involves narrowing.
C — Thickening of the heart muscle is cardiomyopathy, not CAD.
D — Weakening of heart valves is valvular disease.
Tested Concept: CAD definition
Source Concept: What is CAD? Narrowing of heart vessels
,2 The nurse is providing health education to a community group. What is the number
one cause of death for men and women in the United States?
A Coronary artery disease (CAD)
B Cancer
C Stroke
D Diabetes mellitus
Correct Answer: A Coronary artery disease (CAD) is the number one cause of death for
both men and women in the United States.
B — Cancer is the second leading cause of death.
C — Stroke is a leading cause of death but not number one.
D — Diabetes is a significant cause of death but not number one.
Tested Concept: CAD — leading cause of death
Source Concept: What is the number one cause of death for men and women in the US? CAD
3 The nurse is teaching a client about the pathophysiology of CAD. What is the most
common cause of CAD?
A Atherosclerosis (plaque buildup)
B Congenital heart defects
C Valvular stenosis
D Myocarditis
Correct Answer: A The most common cause of CAD is atherosclerosis, which involves
plaque buildup within the coronary arteries, leading to narrowing and reduced blood flow.
B — Congenital heart defects are present at birth and are not the most common cause.
C — Valvular stenosis affects heart valves, not coronary arteries.
D — Myocarditis is inflammation of the heart muscle.
Tested Concept: CAD — most common cause
Source Concept: What is the most common cause of CAD? Atherosclerosis (plaque buildup)
, 4 A client asks the nurse when CAD typically begins to manifest symptoms. Which
response by the nurse is correct?
A Symptoms manifest at approximately 40% blockage
B Symptoms manifest at approximately 50% blockage
C Symptoms manifest at approximately 70% blockage
D Symptoms manifest at approximately 90% blockage
Correct Answer: A CAD typically manifests symptoms when there is approximately 40%
blockage of the coronary artery, as the vessel is significantly narrowed and blood flow is
compromised.
B — Symptoms may not wait until 50% blockage.
C — 70% blockage would cause severe symptoms.
D — 90% blockage would cause critical ischemia.
Tested Concept: CAD — symptom manifestation
Source Concept: When does CAD manifest symptoms? 40% blockage
5 The nurse is teaching a client about the difference between arteriosclerosis and
atherosclerosis. Which statement by the client indicates understanding?
A "Arteriosclerosis is narrowing of arteries due to hardening."
B "Arteriosclerosis is caused by plaque buildup."
C "Arteriosclerosis and atherosclerosis are the same condition."
D "Arteriosclerosis is a type of heart failure."
Correct Answer: A Arteriosclerosis is the narrowing of arteries due to hardening and loss of
elasticity. Atherosclerosis is a specific type of arteriosclerosis involving plaque buildup.
B — Plaque buildup is atherosclerosis, not arteriosclerosis.
C — They are related but not identical; atherosclerosis is a subtype.
D — Arteriosclerosis is a vascular condition, not heart failure.
Tested Concept: Arteriosclerosis vs. atherosclerosis
Source Concept: What is arteriosclerosis? Narrowing of artery due to hardening
