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?

A) "The headaches should decrease as you get used to the medication.": This statement is correct. A common side effect of isosorbide dinitrate is headaches, as the medication works by dilating blood vessels, which can cause a drop in blood pressure. These headaches typically occur when the medication starts, but they often decrease over time as the body adjusts to the drug. The nurse should reassure the client that this side effect is generally temporary. B) "You should take the medication on an empty stomach to prevent a headache.": This statement is incorrect. While taking certain medications on an empty stomach may affect their absorption, isosorbide dinitrate is typically not recommended to be taken on an empty stomach to avoid headaches. In fact, it is more common for people to take it with food if it causes gastrointestinal discomfort, but this is not directly related to preventing headaches. C) "You can discontinue the medication until the headache goes away.": This statement is incorrect. The client should not discontinue the medication without consulting the healthcare provider. Abruptly stopping isosorbide dinitrate can lead to withdrawal symptoms and potentially worsen the client's condition. The nurse should encourage the client to talk to their provider if the headache becomes unbearable or persistent, but not to stop the medication without guidance. D) "Swallow the tablet whole to minimize your headaches.": This statement is incorrect. Isosorbide dinitrate in chewable form is designed to be chewed, as this method of administration helps the drug be absorbed more quickly and effectively. Swallowing the tablet whole would not address the issue of headaches and could affect how the medication works.
