Cardiovascular System Exam Questions Pdf

1. What is a condition where the blood supply to the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients?

Correct answer: A

Rationale: A stroke is the correct answer. A stroke occurs when the blood supply to part of the brain is interrupted or reduced, leading to a lack of oxygen and nutrients to the brain tissue, causing brain damage. Choices B, C, and D are incorrect because a transient ischemic attack (TIA) is a temporary blockage of blood flow to the brain with no lasting damage, myocardial infarction is a heart attack due to blockage of blood flow to the heart muscle, and angina is chest pain caused by reduced blood flow to the heart.

2. Which type of medication is used to reduce the workload on the heart by slowing down the heart rate and lowering blood pressure?

Correct answer: A

Rationale: The correct answer is A: Beta-blocker. Beta-blockers are medications that reduce the workload on the heart by slowing down the heart rate and lowering blood pressure. They are commonly used in the treatment of heart conditions such as hypertension and heart failure. ACE inhibitors (B) work by dilating blood vessels to reduce blood pressure, calcium channel blockers (C) prevent calcium from entering the heart muscle and blood vessel walls, and diuretics (D) help the body get rid of excess salt and water by increasing urine production.

3. The client has a prescription for sublingual nitroglycerin. What is the nurse's instruction for how to take this medication during an episode of chest pain?

Correct answer: A

Rationale: The correct answer is A. The standard instruction for sublingual nitroglycerin during an episode of chest pain is to take one tablet every 5 minutes, up to three tablets. If the pain persists after taking three tablets, the client should seek emergency help. Choice B is incorrect because taking one tablet every hour is not the appropriate dosing for acute chest pain. Choice C is incorrect as taking two tablets immediately is not in line with the recommended dosing instructions. Choice D is incorrect because sublingual nitroglycerin should be placed under the tongue, not swallowed with water.

4. What is a condition where the right side of the heart fails due to increased pressure in the pulmonary arteries, often caused by chronic lung disease?

Correct answer: A

Rationale: Cor pulmonale is the correct answer. It is a condition where the right side of the heart fails due to increased pressure in the pulmonary arteries, often caused by chronic lung disease such as COPD. Pulmonary embolism (choice C) is a blockage in one of the pulmonary arteries in your lungs. Myocarditis (choice D) is inflammation of the heart muscle. While heart failure (choice B) is a broad term that can involve the failure of either the right or left side of the heart.

5. The healthcare provider is monitoring a client on an ACE inhibitor. What lab value is most important to monitor?

Correct answer: A

Rationale: The correct answer is A: Potassium. When a client is on an ACE inhibitor, it is crucial to monitor potassium levels because ACE inhibitors can lead to an increase in potassium, potentially causing hyperkalemia. Monitoring sodium levels (Choice B) is not as critical in this scenario. Creatinine levels (Choice C) are important for assessing kidney function but are not the most crucial lab value to monitor with ACE inhibitors. Calcium levels (Choice D) are not directly affected by ACE inhibitors and are not the priority for monitoring in this case.
