1. Which artery supplies the right atrium, right ventricle, a portion of the septum, SA node, AV node, and inferior portion of the left ventricle?

• A. Right coronary artery
• B. Left circumflex artery
• C. Posterior descending artery
• D. Aortic artery

Correct answer: A

Rationale: The correct answer is the right coronary artery. It supplies essential areas of the heart, including the right atrium, right ventricle, a portion of the septum, SA node, AV node, and the inferior portion of the left ventricle. The left circumflex artery primarily supplies the left atrium and lateral wall of the left ventricle, not the mentioned areas. The posterior descending artery supplies the inferior wall of the left ventricle, not the right side. The aortic artery is a general term and does not specifically refer to an artery that supplies the mentioned areas.

2. The client on amiodarone develops pulmonary fibrosis. What action should the nurse take?

• A. Notify the healthcare provider immediately.
• B. Continue the medication and monitor lung function.
• C. Discontinue the medication and start oxygen therapy.
• D. Reduce the dose and monitor respiratory status.

Correct answer: A

Rationale: When a client on amiodarone develops pulmonary fibrosis, a serious side effect, the immediate action the nurse should take is to notify the healthcare provider. This is crucial because pulmonary fibrosis can lead to severe respiratory compromise and requires prompt evaluation and management by the healthcare provider. Continuing the medication (choice B) can worsen the condition, and delaying action by reducing the dose and monitoring respiratory status (choice D) may not be appropriate given the seriousness of pulmonary fibrosis. Discontinuing the medication and starting oxygen therapy (choice C) may be necessary, but the priority is to notify the healthcare provider first for further assessment and guidance.

3. The client is given an alpha agonist. What might it be used for?

• A. For hemostasis
• B. To dilate the arteries
• C. To dilate the veins
• D. To decrease afterload

Correct answer: A

Rationale: Alpha agonists are used for hemostasis to help control bleeding by constricting blood vessels, leading to decreased blood flow to the area. Choices B, C, and D are incorrect as alpha agonists do not typically dilate arteries, dilate veins, or decrease afterload.

4. The nurse is administering nitroglycerin IV to a client with chest pain. What is the most important parameter to monitor?

• A. Blood pressure
• B. Heart rate
• C. Oxygen saturation
• D. Respiratory rate

Correct answer: A

Rationale: The correct answer is A: Blood pressure. When administering nitroglycerin IV to a client with chest pain, monitoring blood pressure is crucial as nitroglycerin can cause significant hypotension. While heart rate, oxygen saturation, and respiratory rate are important parameters to assess, blood pressure takes precedence in this scenario due to the potential hypotensive effects of nitroglycerin.

5. What is a chronic condition where the heart muscle becomes weakened and enlarged, reducing its ability to pump blood effectively?

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

Correct answer: A

Rationale: Dilated cardiomyopathy is characterized by the weakening and enlargement of the heart muscle, leading to its reduced ability to pump blood effectively. This condition is different from hypertrophic cardiomyopathy, which involves abnormal thickening of the heart muscle, myocarditis, which is inflammation of the heart muscle, and pericarditis, which is inflammation of the pericardium. Therefore, the correct answer is Dilated cardiomyopathy.
