A nurse is reinforcing teaching with a client who has a duodenal ulcer and a new prescription for cimetidine. Which of the following instructions should the nurse include?

Sucralfate is a medication used to treat peptic ulcers by forming a protective coating on the stomach lining. It should be taken on an empty stomach, as food can interfere with its absorption and effectiveness. One hour before breakfast and the evening meal is the correct timing for administering sucralfate, allowing for an empty stomach before meals.

At the time the client takes a proton pump inhibitor: Proton pump inhibitors are a different class of medications used to reduce stomach acid production. It is recommended to administer sucralfate separately, as it works differently and has different administration requirements.

Thirty minutes after breakfast and the evening meal: Administering sucralfate after meals is not ideal, as it may not provide the desired therapeutic effect on an empty stomach.

The time the client takes an antacid: Antacids are also different from sucralfate, and they can interfere with its absorption. It is generally recommended to administer sucralfate separately from antacids.

Hydrochlorothiazide is a thiazide diuretic commonly used to treat hypertension and edema. One of the potential side effects of hydrochlorothiazide is hypokalemia (low potassium levels). To help counteract this effect, it is important for the client to increase their daily intake of foods high in potassium, such as bananas, oranges, spinach, avocados, and potatoes. This helps maintain adequate potassium levels in the body.

The other options mentioned are incorrect:

Take the medication on an empty stomach: Hydrochlorothiazide can be taken with or without food. It does not need to be taken on an empty stomach.

Muscle weakness is an expected adverse effect: Muscle weakness is not a common or expected adverse effect of hydrochlorothiazide. If the client experiences muscle weakness, they should notify their healthcare provider.

Take the medication at bedtime: Hydrochlorothiazide can be taken at any time of the day. There is no specific requirement to take it at bedtime. The dosing schedule should be determined based on the individual's needs and healthcare provider's instructions.
