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) *Restrict your daily fluid intake: Restricting fluid intake is not recommended for a client experiencing lightheadedness upon standing, especially when taking an ACE inhibitor. In fact, maintaining adequate hydration is important to help prevent hypotension, which could be exacerbated by fluid restriction. The lightheadedness may be due to orthostatic hypotension, which is a common side effect of ACE inhibitors.

B) *Take a daily potassium supplement: ACE inhibitors can increase potassium levels in the blood, potentially leading to hyperkalemia. For most clients, taking a potassium supplement is not necessary unless specified by the healthcare provider. In fact, many clients taking ACE inhibitors need to avoid excessive potassium intake, unless directed otherwise, to prevent dangerous potassium levels.

C) *Discontinue this medication if this occurs again: The nurse should not advise the client to discontinue the medication without consulting the healthcare provider. Lightheadedness upon standing is a common side effect of ACE inhibitors due to their blood pressure-lowering effects, and the healthcare provider should be notified if this becomes problematic. The decision to change or discontinue the medication should be made by the provider.

D) "Sit back down for a few minutes when this occurs": This is the most appropriate advice. Lightheadedness upon standing can be a sign of orthostatic hypotension, which is a known side effect of ACE inhibitors. The client should be instructed to sit down and rest when they experience these symptoms. If necessary, they should stand up slowly to allow their body to adjust to changes in position, which can help alleviate the lightheadedness.

A) Time: The time of administration is an important factor to clarify. The prescription specifies erythromycin 500mg four times per day, but it does not specify the exact times the medication should be administered. The nurse should clarify the specific times to ensure the medication is given at proper intervals, especially considering the potential for drug interactions and the timing of meals, which may impact absorption.

B) Dosage: The dosage of 500mg is specified clearly in the prescription. There is no indication that the dosage is incorrect or needs clarification. Erythromycin 500mg four times per day is a standard dose for certain infections, so no issues are apparent with the dosage itself.

C) Route: The route of administration (oral, intravenous, etc.) is not specified in the question but is typically understood unless otherwise stated. However, in the context of erythromycin, the most common route is oral. Unless there’s uncertainty about the route, it does not need clarification.

D) Medication: The medication is clearly identified as erythromycin, which is a known antibiotic. There is no ambiguity in the medication prescribed, so there is no need for clarification in this regard. The focus should be on confirming the time of administration.
