Nursing Elites

1. The client is on nitroglycerin and reports chest pain. What is the nurse’s priority action?

• A. Administer nitroglycerin as ordered.
• B. Administer morphine as ordered.
• C. Administer aspirin as ordered.
• D. Notify the healthcare provider immediately.

Correct answer: D

Rationale: The correct answer is D: Notify the healthcare provider immediately. If a client on nitroglycerin reports chest pain, the priority action is to notify the healthcare provider immediately. This is crucial to ensure prompt reassessment of the client's condition and treatment plan. Administering nitroglycerin, morphine, or aspirin without consulting the healthcare provider first can be risky as the chest pain may indicate a need for a change in treatment or further evaluation. Administering medications without proper assessment and guidance can lead to complications and is not recommended in this scenario.

2. Which of the following is a chronic condition where the heart muscle is weakened and unable to pump blood effectively, often leading to heart failure?

• A. Dilated cardiomyopathy
• B. Hypertrophic cardiomyopathy
• C. Restrictive cardiomyopathy
• D. Myocarditis

Correct answer: A

Rationale: Dilated cardiomyopathy is characterized by the heart muscle being weakened and unable to pump blood effectively, ultimately resulting in heart failure. Choice B, Hypertrophic cardiomyopathy, involves the heart muscle becoming abnormally thick, reducing the heart's efficiency. Choice C, Restrictive cardiomyopathy, refers to the heart becoming rigid and less able to fill with blood properly. Myocarditis, as in Choice D, is inflammation of the heart muscle usually caused by a viral infection and is different from the chronic weakening seen in dilated cardiomyopathy.

3. Which heart chamber ejects blood into the systemic arterial circulation via the aorta?

• A. Right atrium
• B. Left atrium
• C. Right ventricle
• D. Left ventricle

Correct answer: D

Rationale: The correct answer is D, Left ventricle. The left ventricle pumps oxygenated blood into the systemic circulation via the aorta. This chamber receives oxygen-rich blood from the left atrium and contracts forcefully to propel blood into the aorta, distributing it to the body. The other options, right atrium, left atrium, and right ventricle, do not directly eject blood into the systemic arterial circulation via the aorta. The right atrium receives deoxygenated blood from the body, the left atrium receives oxygenated blood from the lungs, and the right ventricle pumps blood to the lungs for oxygenation.

4. Which valve prevents backflow of blood into the right ventricle from the pulmonary artery?

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

Correct answer: A

Rationale: The correct answer is the Pulmonary valve. The Pulmonary valve prevents backflow of blood into the right ventricle from the pulmonary artery after it has been ejected. The Aortic valve (choice B) prevents backflow from the aorta into the left ventricle. The Tricuspid valve (choice C) prevents backflow of blood into the right atrium from the right ventricle. The Mitral valve (choice D) prevents backflow from the left ventricle into the left atrium.

5. The nurse is caring for a client on amiodarone who develops a cough. What is the most appropriate action?

• A. Notify the healthcare provider immediately.
• B. Reassure the client that this is a common side effect.
• C. Continue the amiodarone and monitor the client’s symptoms.
• D. Discontinue the amiodarone immediately.

Correct answer: A

Rationale: The correct action when a client on amiodarone develops a cough, which can be a sign of pulmonary toxicity, a serious side effect of amiodarone, is to notify the healthcare provider immediately. This is crucial because pulmonary toxicity can lead to severe complications if not addressed promptly. Choices B and C are incorrect as they do not address the potential severity of the situation and may delay necessary intervention. Choice D of discontinuing amiodarone immediately without consulting the healthcare provider can be risky, as sudden discontinuation of the medication may have adverse effects on the client's condition.
