Amlodipine (Norvasc) has been ordered for a client with newly diagnosed Prinzmetal's (variant) angina. The nurse knows the purpose of the amlodipine is to do which of the following?

It decreases spasm of the coronary arteries

It increases the force of myocardial contraction

It helps prevent clotting in the coronary arteries.

It reduces the "fight or flight" response.

Answer and Explanation

The Correct Answer is A

A. It decreases spasm of the coronary arteries: Amlodipine is a calcium channel blocker that relaxes vascular smooth muscle, making it effective in treating coronary artery spasms in Prinzmetal's angina.

B. It increases the force of myocardial contraction: Amlodipine does not increase myocardial contractility; it primarily affects vascular tone.

C. It helps prevent clotting in the coronary arteries: Amlodipine is not an anticoagulant or antiplatelet agent.

D. It reduces the "fight or flight" response: Beta-blockers, not amlodipine, are typically associated with reducing the sympathetic nervous system response.

Correct Answer is A

Explanation

A. Administer oxygen via nasal cannula: The client's symptoms of dyspnea, chest pain, syncope, and hypotension suggest a possible acute cardiovascular event, such as a myocardial infarction (MI) or pulmonary embolism (PE). Administering oxygen should be the priority to improve oxygenation and prevent hypoxia, which could exacerbate the client's symptoms and further compromise cardiac function.

B. Administer prescribed pain medications. Pain relief may be necessary, but stabilizing oxygen levels is the priority.

C. Administer NS IV fluid. Fluid administration may be helpful, but oxygenation is more critical in this situation to address the potential underlying respiratory or cardiac issue.

D. Ask the provider for a dopamine prescription. While dopamine may be used in cases of shock, the immediate action should be to ensure the client is adequately oxygenated.

A. Removing the cast correctly at the end of the treatment period B. Using crutches efficiently C. Exercising joints above and below the cast, as prescribed D. Reporting signs of impaired circulation

Correct Answer is D

Explanation

A. Removing the cast correctly at the end of the treatment period. The nurse would not instruct the patient to remove the cast. This should be done by a healthcare provider at the appropriate time.

B. Using crutches efficiently. While crutch use is important, it is secondary to monitoring for impaired circulation, which can have immediate, serious consequences.

C. Exercising joints above and below the cast, as prescribed. This may be part of rehabilitation but does not have the same urgency as monitoring circulation for complications.

D. Reporting signs of impaired circulation. The nurse should emphasize the importance of monitoring for signs of impaired circulation, such as increased pain, numbness, or color changes, which could indicate complications like compartment syndrome or poor blood flow.
