A nurse is caring for a client who reports he has headaches after taking chewable isosorbide dinitrate. Which of the following statements should the nurse make?

Headaches are a common side effect of isosorbide dinitrate, especially when initially starting the medication. However, they often improve as the body adjusts to the medication. It is important to reassure the client that the headaches should decrease over time. If the headaches persist or worsen, the client should inform their healthcare provider for further evaluation and possible adjustment of the medication regimen. The statement about taking the medication on an empty stomach is not relevant to preventing headaches associated with isosorbide dinitrate. The statement about swallowing the tablet whole does not address the issue of headaches. Chewable isosorbide dinitrate is designed to be chewed or dissolved in the mouth, and swallowing it whole may not provide the intended therapeutic effect. Discontinuing the medication until the headache goes away is not recommended without consulting the healthcare provider. Abruptly stopping or changing the dose of isosorbide dinitrate can have serious consequences and should only be done under medical supervision.
