Question 1 of 5

The client with chronic, stable angina telephones the clinic nurse and reports a headache lasting for several days after taking one dose of isosorbide mononitrate. The client also reports symptoms of orthostatic hypotension and palpitations. Which is the nurse's best action?

Correct Answer: A

Rationale: A: Severe headaches, orthostatic hypotension, and palpitations may be a sign of isosorbide mononitrate (Imdur) toxicity; thus, the client should be evaluated by an HCP. Other signs of toxicity include syncope, dizziness, blurred vision, and light-headedness. B: Isosorbide mononitrate should be taken in the morning to improve blood flow to the heart and prevent angina attacks that can occur due to increased oxygen demand from activity. C: A headache (but not a severe headache) can be treated with or prevented by analgesics taken either before or at the same time as the isosorbide mononitrate. D: Although the headaches will subside over time, the client is experiencing symptoms of isosorbide mononitrate toxicity.
