Cardiovascular System Exam Questions

1. The client on spironolactone (Aldactone) should avoid which type of food?

Correct answer: A

Rationale: The correct answer is A: Foods high in potassium. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium and excrete sodium. Therefore, clients on spironolactone should avoid foods high in potassium to prevent hyperkalemia, which is an elevated level of potassium in the blood. Choices B, C, and D are incorrect because spironolactone specifically affects potassium levels, not sodium, calcium, or chloride.

2. What type of medication is used to reduce inflammation in the airways and prevent asthma attacks?

Correct answer: A

Rationale: The correct answer is A, Corticosteroid. Corticosteroids are medications that work by reducing inflammation in the airways, helping to prevent asthma attacks and manage chronic respiratory conditions. Bronchodilators (choice B) work by relaxing the muscles around the airways to make breathing easier, but they do not primarily target inflammation. Antihistamines (choice C) are used to treat allergic reactions and do not directly target airway inflammation. Mucolytics (choice D) help to break down and thin mucus in the airways but do not reduce inflammation.

3. This term refers to a change in the inotropic state of the muscle without a change in myocardial fiber length.

Correct answer: A

Rationale: The correct answer is A: Contractility. Contractility specifically refers to the change in the force of contraction of the heart muscle without changing its length. In this scenario, the focus is on the change in the inotropic state of the muscle, which directly relates to contractility. Choice B, Excitability, refers to the ability of a cell to respond to a stimulus, not specifically related to changes in contractile force. Choice C, Refractoriness, pertains to the period during which a cell is unresponsive to a new stimulus. Choice D, Automaticity, refers to the ability of cardiac cells to spontaneously generate electrical impulses.

4. What diagnostic procedure uses sound waves to create images of the heart and assess its structure and function?

Correct answer: A

Rationale: An echocardiogram is the correct answer because it is a diagnostic procedure that uses sound waves to create images of the heart, enabling doctors to assess its structure and function. This imaging technique is specifically designed for cardiac assessment. MRI (Choice B), CT scan (Choice C), and X-ray (Choice D) are imaging modalities that are not primarily used for detailed evaluation of the heart's structure and function, making them incorrect choices for this question.

5. The nurse is caring for a client on amiodarone who complains of visual disturbances. What is the nurse’s best response?

Correct answer: A

Rationale: The correct answer is to notify the healthcare provider immediately. Visual disturbances in a client taking amiodarone can indicate amiodarone toxicity, a serious side effect. Notifying the healthcare provider promptly is essential for further assessment and management. Reassuring the client that this is a common side effect (choice B) is incorrect as visual disturbances should not be dismissed without evaluation. Advising the client to monitor their symptoms at home (choice C) may delay necessary intervention. Suggesting the client reduce physical activity (choice D) is unrelated to addressing visual disturbances caused by amiodarone.
