Cardiovascular System Exam Questions

1. The nurse is teaching a client about side effects of ACE inhibitors. What is the most important side effect to monitor?

Correct answer: A

Rationale: The correct answer is A: Cough. ACE inhibitors commonly cause a persistent dry cough in patients. This side effect is important to monitor because it can indicate the development of angioedema, a serious adverse reaction that requires immediate medical attention. Hyperkalemia (choice B) is a potential side effect of ACE inhibitors but is not typically the most important one to monitor. Hypotension (choice C) and dizziness (choice D) are also possible side effects of ACE inhibitors, but they are not as critical to monitor as the development of a persistent cough.

2. What term describes the phenomenon wherein decreased BP causes a reflex SNS response with increased pulse, increased contractility, and vasoconstriction; and increased BP causes reflex vagal responses resulting in decreased heart rate and passive vasodilation in the systemic arterioles?

Correct answer: A

Rationale: The correct answer is A: Baroreflex. The Baroreflex is a mechanism by which the body maintains blood pressure homeostasis through reflexive adjustments in heart rate and vascular tone. Choice B, Cheyne-Stokes breathing, is a pattern of breathing characterized by progressively deeper and sometimes faster breathing, followed by a gradual decrease that results in a temporary stop in breathing. Choices C and D, Frank-Starling Law and Starling reflex, are related to the intrinsic ability of the heart to adjust its output based on venous return, not specifically regulating blood pressure through reflex adjustments in heart rate and vascular tone as seen in the described phenomenon.

3. What is a condition where the heart muscle becomes abnormally enlarged, thickened, or stiffened, often leading to heart failure?

Correct answer: A

Rationale: Cardiomyopathy is the correct answer. It is a condition characterized by the abnormal enlargement, thickening, or stiffening of the heart muscle, which can lead to heart failure. Pericarditis (choice B) is inflammation of the pericardium, the sac surrounding the heart, not directly related to heart muscle enlargement. Aortic stenosis (choice C) is the narrowing of the aortic valve opening, affecting blood flow from the heart, but not directly related to heart muscle enlargement. Mitral valve prolapse (choice D) is a condition where the valve between the left atrium and left ventricle doesn't close properly, causing blood to leak backward, and is not directly related to heart muscle enlargement.

4. Which heart chamber ejects blood into the systemic arterial circulation via the aorta?

Correct answer: D

Rationale: The correct answer is D, Left ventricle. The left ventricle pumps oxygenated blood into the systemic circulation via the aorta. This chamber receives oxygen-rich blood from the left atrium and contracts forcefully to propel blood into the aorta, distributing it to the body. The other options, right atrium, left atrium, and right ventricle, do not directly eject blood into the systemic arterial circulation via the aorta. The right atrium receives deoxygenated blood from the body, the left atrium receives oxygenated blood from the lungs, and the right ventricle pumps blood to the lungs for oxygenation.

5. Which condition involves the body's immune system attacking the lungs and kidneys, causing severe respiratory and renal damage?

Correct answer: A

Rationale: Goodpasture syndrome is the correct answer. It is an autoimmune disease characterized by the immune system attacking the lungs and kidneys, leading to bleeding in the lungs and kidney failure. Sarcoidosis primarily affects the lungs and lymph nodes, not the kidneys. Wegener's granulomatosis affects the lungs, sinuses, and kidneys, but it is characterized by inflammation of blood vessels. Interstitial lung disease involves scarring of the lung tissue, not direct immune system attacks on the lungs and kidneys.
