A nurse is caring client who has peptic ulcer disease and is scheduled to undergo an esophagogastroduodenoscopy. Which of the following actions should the nurse take prior to the procedure?

A) Withhold the medication if pulse rate is less than 60/min: Enalapril, an ACE inhibitor, primarily affects blood pressure and does not typically require withholding based on pulse rate alone. Withholding enalapril is not recommended unless instructed by the healthcare provider for other reasons, such as a significant drop in blood pressure. The issue at hand is likely related to orthostatic hypotension rather than pulse rate.

B) Increase dietary potassium: Enalapril can increase potassium levels in the blood due to its effect on the renin-angiotensin system, potentially leading to hyperkalemia. Clients should avoid excessive potassium intake, especially through supplements or potassium-rich foods, unless advised by their healthcare provider. Increasing potassium may exacerbate any existing risks.

C) Decrease daily fluid intake: Decreasing fluid intake is not a recommended intervention for managing syncope related to enalapril. In fact, reducing fluid intake can exacerbate dehydration or low blood pressure, potentially worsening symptoms. Adequate hydration is typically important for managing blood pressure and syncope risk.

D) Rise slowly from a sitting position to a standing position: This is the most appropriate
advice. Enalapril can cause orthostatic hypotension, a condition in which blood pressure drops when changing positions (such as from sitting to standing). This can lead to dizziness or syncope. Rising slowly from a sitting position helps prevent a sudden drop in blood pressure and reduces the risk of fainting. Clients should be instructed to take this precaution until the body adjusts to the medication’s effects.

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.
