Nursing Elites

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

• A. Reassure the client that the cough is a common side effect and is usually not serious.
• B. Instruct the client to report the cough to the healthcare provider as it may require discontinuation of the medication.
• C. Advise the client to use a humidifier at night to relieve the cough.
• D. Suggest the client take an over-the-counter cough suppressant.

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.

2. 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?

• A. Heart failure
• B. Cardiomyopathy
• C. Pericarditis
• D. Myocarditis

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.

3. Which fibers distribute the electrical impulse to the ventricles, causing them to contract?

• A. Purkinje fibers
• B. SA node
• C. AV node
• D. Bundle of His

Correct answer: A

Rationale: The correct answer is Purkinje fibers. Purkinje fibers are specialized conducting fibers that distribute the electrical impulse to the ventricles, leading to their contraction. The SA node (sinoatrial node) is responsible for initiating the electrical impulse in the heart, the AV node (atrioventricular node) delays the impulse to allow for proper atrial contraction before ventricular contraction, and the Bundle of His transmits the impulse from the AV node to the ventricles. Therefore, choices B, C, and D are not the correct options for fibers directly distributing the impulse to the ventricles.

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

• A. Notify the healthcare provider immediately.
• B. Reassure the client that this is a common side effect.
• C. Advise the client to monitor their symptoms at home.
• D. Suggest the client reduce physical activity.

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.

5. Which valve prevents backflow of blood into the left ventricle from the aorta?

• A. Aortic valve
• B. Mitral valve
• C. Tricuspid valve
• D. Pulmonary valve

Correct answer: A

Rationale: The correct answer is Aortic valve. The aortic valve is positioned between the left ventricle and the aorta. It prevents blood from flowing back into the left ventricle after it has been pumped into the aorta. The mitral valve (Choice B) is located between the left atrium and the left ventricle, the tricuspid valve (Choice C) is between the right atrium and right ventricle, and the pulmonary valve (Choice D) is situated between the right ventricle and the pulmonary artery. Therefore, they are not responsible for preventing backflow from the aorta into the left ventricle.
