1. What is the accumulation of fatty deposits along the walls of arteries, leading to reduced blood flow?

• A. Atherosclerosis
• B. Arteriosclerosis
• C. Aneurysm
• D. Thrombosis

Correct answer: A

Rationale: Atherosclerosis is the correct answer. It refers to the buildup of fatty deposits (plaque) along the inner walls of arteries, narrowing the blood vessels and reducing blood flow. This condition can lead to serious complications such as heart attacks or strokes. Arteriosclerosis (choice B) is a broader term that refers to the thickening and hardening of the arterial walls. While related, it is not as specific as atherosclerosis in describing the fatty deposit accumulation. Aneurysm (choice C) is the abnormal bulging of an artery wall that can rupture and cause internal bleeding, not specifically related to fatty deposits. Thrombosis (choice D) is the formation of a blood clot within a blood vessel, which can obstruct blood flow, but it is not directly related to the accumulation of fatty deposits.

2. The client is on a calcium channel blocker. What is the expected effect on the heart?

• A. Increased heart rate
• B. Decreased heart rate
• C. Increased blood pressure
• D. Decreased blood pressure

Correct answer: D

Rationale: When a client is on a calcium channel blocker, the expected effect on the heart is a decreased heart rate and decreased blood pressure. Calcium channel blockers work by dilating blood vessels and reducing the heart's workload, resulting in decreased blood pressure. Choice A, increased heart rate, is incorrect as calcium channel blockers actually have a negative chronotropic effect, reducing the heart rate. Choice C, increased blood pressure, is also incorrect because these medications are used to lower blood pressure.

3. What is a condition where the arteries that supply blood to the heart muscle become hardened and narrowed due to the buildup of plaque?

• A. Atherosclerosis
• B. Aneurysm
• C. Arrhythmia
• D. Peripheral artery disease

Correct answer: A

Rationale: Atherosclerosis is the correct answer. It is a condition characterized by the hardening and narrowing of arteries supplying blood to the heart due to plaque buildup. This condition increases the risk of heart attacks. Choice B, aneurysm, refers to a balloon-like bulge in an artery, not the hardening and narrowing of arteries. Choice C, arrhythmia, is an irregular heartbeat and not related to arterial hardening. Choice D, peripheral artery disease, involves the narrowing of arteries that supply blood to the limbs, not specifically to the heart.

4. Which artery supplies the anterior wall of the left ventricle, the anterior interventricular septum, the anterior papillary muscles, and apex of the heart?

• A. Left anterior descending artery
• B. Left circumflex artery
• C. Posterior descending artery
• D. Aortic artery

Correct answer: A

Rationale: The correct answer is the Left anterior descending artery. This artery supplies the anterior wall of the left ventricle, the anterior interventricular septum, the anterior papillary muscles, and apex of the heart. The Left circumflex artery (choice B) supplies the lateral and posterior walls of the left ventricle, the posterior descending artery (choice C) supplies the inferior part of the heart, and the aortic artery (choice D) is not a specific coronary artery.

5. What is a condition where the heart is unable to pump blood effectively, leading to a buildup of fluid in the lungs and other parts of the body?

• A. Heart failure
• B. Cardiomyopathy
• C. Myocardial infarction
• D. Pulmonary edema

Correct answer: A

Rationale: The correct answer is A: Heart failure. Heart failure occurs when the heart is unable to pump blood effectively, resulting in a buildup of fluid in the lungs and other parts of the body. Choice B, Cardiomyopathy, refers to diseases of the heart muscle, not specifically the inability to pump blood effectively. Choice C, Myocardial infarction, is a heart attack caused by a blocked blood supply to the heart muscle, not directly related to the heart's pumping efficiency. Choice D, Pulmonary edema, is a condition characterized by fluid accumulation in the lungs, often a consequence of heart failure but not the primary condition described in the question.
