Cardiovascular System Exam Questions Pdf

Correct Answer: A

Rationale: Mitral valve prolapse is the correct answer. It occurs when the mitral valve does not close properly, leading to blood leaking backward into the left atrium. This condition can manifest with symptoms such as palpitations and chest pain. Choices B, C, and D are incorrect because aortic stenosis involves narrowing of the aortic valve, mitral stenosis is the narrowing of the mitral valve, and tricuspid regurgitation is when blood leaks backward through the tricuspid valve.

Correct Answer: C

Rationale: The correct answer is C: Increased cardiac output. ACE inhibitors are commonly used in heart failure to reduce the workload on the heart by decreasing blood pressure and increasing cardiac output. This ultimately helps improve the heart's efficiency and function. Choice A is incorrect because ACE inhibitors generally lead to a reduction in blood pressure. Choice B is incorrect as ACE inhibitors do not increase heart rate. Choice D is incorrect as ACE inhibitors do not typically decrease heart rate in the context of heart failure.

Correct Answer: A

Rationale: The correct answer is A: Blood pressure. When administering nitroglycerin IV to a client with chest pain, monitoring blood pressure is crucial as nitroglycerin can cause significant hypotension. While heart rate, oxygen saturation, and respiratory rate are important parameters to assess, blood pressure takes precedence in this scenario due to the potential hypotensive effects of nitroglycerin.

Correct Answer: A

Rationale: Hypertension, also known as high blood pressure, is a chronic condition characterized by persistently elevated pressure in the arteries. This condition increases the risk of heart disease, stroke, and other health issues. Hypotension (choice B) refers to low blood pressure and is not the correct answer. Hyperlipidemia (choice C) is high levels of fats in the blood, not related to blood pressure. Hyperglycemia (choice D) is high blood sugar levels, not directly related to elevated blood pressure.

Correct Answer: A

Rationale: The correct answer is Angioplasty. Angioplasty is a procedure where a catheter is used to open a blocked or narrowed coronary artery, often involving the placement of a stent to keep the artery open and improve blood flow to the heart. Choice B, Valve replacement, is incorrect as it involves replacing a heart valve, not opening a blocked artery. Choice C, Stent placement, is similar to angioplasty but not as specific, as it does not involve the catheter-based procedure. Choice D, Coronary artery bypass graft (CABG), is a different procedure where blocked arteries are bypassed using a blood vessel from another part of the body.
