Cardiovascular System Exam Questions And Answers

1. The client on furosemide (Lasix) has a potassium level of 3.1 mEq/L. What is the nurse’s priority action?

Correct answer: A

Rationale: The correct answer is to administer a potassium supplement. A potassium level of 3.1 mEq/L indicates hypokalemia, which can lead to serious complications like cardiac dysrhythmias. Therefore, the priority action is to address the low potassium level by administering a potassium supplement. Holding the furosemide (Choice B) may be necessary in the long term to prevent further potassium loss, but the immediate need is to correct the low potassium level. Continuing the current dose of furosemide (Choice C) without addressing the low potassium level can worsen hypokalemia. Administering Digibind (Choice D) is not indicated for low potassium levels; Digibind is used to treat digoxin toxicity.

2. The client is on furosemide (Lasix) and has a potassium level of 2.9 mEq/L. What is the nurse’s priority action?

Correct answer: A

Rationale: The correct answer is A: Administer potassium supplements. A potassium level of 2.9 mEq/L indicates hypokalemia (low potassium levels). Furosemide (Lasix) is a loop diuretic that can cause potassium loss. Therefore, the priority action is to administer potassium supplements to correct the imbalance. Option B is incorrect because holding the furosemide without addressing the low potassium level could further worsen the imbalance. Option C is incorrect as continuing the current dose of furosemide without addressing the low potassium level could lead to complications. Option D is incorrect because decreasing the dose of furosemide does not directly address the low potassium level that needs immediate correction.

3. The client is receiving intravenous dopamine. What is the most important nursing assessment?

Correct answer: A

Rationale: The correct answer is to monitor heart rate and rhythm when a client is receiving intravenous dopamine. Dopamine is known to potentially cause arrhythmias, making this assessment crucial. While monitoring blood pressure, respiratory rate, and oxygen saturation are important nursing assessments, they are not the most critical when dopamine is being administered.

4. 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.

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

Correct answer: A

Rationale: The correct answer is A, heart failure. Heart failure is a condition where the heart is unable to pump blood effectively, leading to fluid accumulation in the lungs and other areas. Choice B, Cardiomyopathy, refers to diseases of the heart muscle. Choices C and D, Pericarditis and Myocarditis, respectively, are conditions involving inflammation of the outer lining of the heart and the heart muscle itself, which may not always directly result in decreased pumping ability like heart failure does.
