Question

a nurse is teaching a client who has a new prescription for nitroglycerin. the nurse should instruct the client that which of the following manifestations is a potential adverse effect of this medication?

• headache
• constipation
• hypertension
• hyperglycemia

Explanation:

Nitroglycerin is a vasodilator. A common adverse effect of vasodilators like nitroglycerin is headache, due to the dilation of blood vessels in the head. Constipation is not a typical adverse effect of nitroglycerin. Nitroglycerin usually causes hypotension (not hypertension) as it dilates blood vessels, reducing blood pressure. Hyperglycemia is also not a typical adverse effect of this medication.

Answer:

A. Headache
