1. A nurse is assessing a client with left-sided heart failure. Which finding is most
characteristic of this condition?
A. Peripheral edema
B. Jugular venous distention
C. Pulmonary congestion
D. Hepatomegaly
Answer: C
Rationale: Left-sided heart failure causes pulmonary congestion due to the backup of
blood into the pulmonary circulation. This leads to symptoms such as dyspnea, crackles,
and cough. Peripheral edema, JVD, and hepatomegaly are signs of right-sided heart
failure.
2. What is the primary cause of atherosclerosis?
A. Endothelial injury and inflammation
B. Decreased platelet aggregation
C. Increased HDL cholesterol
D. Decreased LDL cholesterol
,Answer: A
Rationale: Atherosclerosis begins with endothelial injury, which triggers an inflammatory
response. Lipids, particularly LDL, accumulate in the vessel wall, leading to plaque
formation. This process is accelerated by hypertension, smoking, and hyperlipidemia.
3. A patient is diagnosed with hypertension. Which of the following is a modifiable
risk factor for this condition?
A. Age
B. Family history
C. Obesity
D. Gender
Answer: C
Rationale: Obesity is a modifiable risk factor for hypertension. Age, family history, and
gender are non-modifiable risk factors. Lifestyle modifications such as weight loss,
exercise, and dietary changes can help manage hypertension.
4. Which of the following is the most common cause of myocardial infarction (MI)?
A. Coronary artery spasm
B. Atherosclerosis with plaque rupture
C. Embolism
D. Vasculitis
Answer: B
Rationale: The most common cause of MI is atherosclerosis with plaque rupture, leading to
thrombus formation and occlusion of a coronary artery. This results in ischemia and
necrosis of the myocardium. Other causes are less common.
5. In a patient with acute myocardial infarction, which cardiac enzyme is the most
specific and sensitive?
,A. Creatine kinase (CK)
B. CK-MB
C. Troponin
D. Lactate dehydrogenase (LDH)
Answer: C
Rationale: Troponin is the most specific and sensitive marker for myocardial injury. It rises
within 3-4 hours and remains elevated for up to 14 days. CK-MB rises in 4-6 hours but is
less specific than troponin.
6. What is the primary pathophysiological mechanism of atherosclerosis?
A. Thickening of the arterial wall due to lipid accumulation
B. Weakening of the arterial wall
C. Spasm of the arterial wall
D. Inflammation of the arterial wall only
Answer: A
Rationale: Atherosclerosis is characterized by the thickening of arterial walls due to lipid
accumulation, particularly LDL cholesterol, within the intima. This process leads to plaque
formation and narrowing of the arterial lumen. Inflammation plays a role but is not the
primary mechanism.
7. A patient presents with chest pain that is relieved by rest and nitroglycerin. This
is most consistent with:
A. Unstable angina
B. Stable angina
C. Myocardial infarction
D. Pericarditis
Answer: B
Rationale: Stable angina is characterized by chest pain that is predictable and relieved by
rest and nitroglycerin. Unstable angina occurs at rest or with minimal exertion and is not
relieved by rest. MI involves persistent chest pain with elevated cardiac enzymes.
, 8. In right-sided heart failure, which of the following findings is expected?
A. Pulmonary edema
B. Hepatomegaly
C. Orthopnea
D. Crackles in the lungs
Answer: B
Rationale: Right-sided heart failure leads to systemic venous congestion, causing
hepatomegaly, peripheral edema, and jugular venous distention. Pulmonary edema,
orthopnea, and crackles are characteristic of left-sided heart failure.
9. Which of the following is a common complication of untreated hypertension?
A. Stroke
B. Myocardial infarction
C. Renal failure
D. All of the above
Answer: D
Rationale: Untreated hypertension can lead to stroke, myocardial infarction, renal failure,
and other complications due to damage to blood vessels and target organs. Early detection
and treatment are essential to prevent these complications.
10. What is the normal range for blood pressure in adults?
A. 90/60-120/80 mmHg
B. 100/60-130/80 mmHg
C. 110/70-140/90 mmHg
D. 120/80-160/100 mmHg
Answer: A
Rationale: The normal blood pressure range for adults is less than 120/80 mmHg.
