Physical Exam Cardiovascular System Questions

Question 1 of 5

What test uses sound waves to create pictures of the heart, allowing doctors to see how well the heart is functioning?

Correct Answer: A

Rationale: The correct answer is an echocardiogram. This test utilizes sound waves to generate images of the heart, enabling doctors to evaluate both the function and structure of the heart. Choice B, MRI, uses magnetic fields and radio waves to produce detailed images of the body's organs and structures, not specifically focused on the heart. Choice C, CT scan, employs X-rays to create detailed cross-sectional images of the body, not primarily for the heart. Choice D, X-ray, uses electromagnetic radiation to produce images of internal structures, but it does not provide the detailed pictures of the heart's function that an echocardiogram does.

Question 2 of 5

The client on spironolactone (Aldactone) has a potassium level of 5.6 mEq/L. What is the nurse's priority action?

Correct Answer: A

Rationale: The correct answer is A: Hold the spironolactone and notify the healthcare provider. A potassium level of 5.6 mEq/L is high, indicating hyperkalemia. Spironolactone is a potassium-sparing diuretic that can further elevate potassium levels. Therefore, the priority action is to withhold the medication to prevent exacerbating hyperkalemia and notify the healthcare provider for further management. Option B is incorrect because administering potassium supplements would worsen the hyperkalemia. Option C is incorrect as continuing spironolactone can lead to a further increase in potassium levels. Option D is incorrect as increasing the dose of spironolactone would be inappropriate in the presence of elevated potassium levels.

Question 3 of 5

A client on a beta blocker has a heart rate of 52 bpm. What is the nurse's priority action?

Correct Answer: A

Rationale: The correct answer is to hold the beta blocker and notify the healthcare provider. A heart rate of 52 bpm is low, and beta blockers can further decrease the heart rate, potentially causing harm. Therefore, withholding the medication and promptly informing the healthcare provider is crucial for further assessment and possible adjustment of the treatment plan. Administering the beta blocker as ordered (Choice B) can exacerbate the bradycardia. Increasing the dose of the beta blocker (Choice C) would further suppress the heart rate. Continuing to monitor the client and reassessing in 30 minutes (Choice D) might delay necessary interventions and increase the risk of complications in a client with a heart rate of 52 bpm.

Question 4 of 5

A client on an ACE inhibitor reports a persistent cough. What is the nurse's best response?

Correct Answer: B

Rationale: The correct answer is B. A persistent cough in a client on an ACE inhibitor may indicate a serious side effect that requires discontinuation of the medication. Instructing the client to report the cough to the healthcare provider is essential for proper evaluation and management. Choice A is incorrect because simply reassuring the client may delay necessary action. Choice C is incorrect as using a humidifier may not address the underlying cause of the cough. Choice D is incorrect because taking a cough suppressant without healthcare provider guidance may mask symptoms without addressing the cause.

Question 5 of 5

The client is prescribed warfarin. What should the client be taught about this medication?

Correct Answer: A

Rationale: The correct answer is A: Avoid foods high in vitamin K. Warfarin is an anticoagulant medication, and vitamin K can counteract its effects. Therefore, it is important for clients taking warfarin to avoid foods high in vitamin K to maintain the medication's effectiveness. Choice B is incorrect because warfarin should be taken consistently as prescribed, regardless of food intake. Choice C is incorrect because while consistency in timing is important, it is not specific to the effectiveness of warfarin. Choice D is incorrect because clients should never increase the dose of warfarin on their own, especially to make up for a missed dose, as it can lead to serious bleeding risks.
