A client with cystitis receives a prescription for phenazopyridine. Which information should the nurse explain to the client about its therapeutic effect?

Choice A reason: While it is true that breastfeeding is not recommended while taking isotretinoin due to the potential for adverse effects on the infant, this is not the most critical information for a client planning to become pregnant. The primary concern is the teratogenic effects of isotretinoin, which can cause severe birth defects.

Choice B reason: Advising the client not to take multiple vitamins that contain vitamin A while on isotretinoin is important because excessive vitamin A can increase the risk of toxicity. However, this is not the most crucial information for someone planning to become pregnant. The teratogenic risks of isotretinoin are a higher priority.

Choice C reason: Obtaining baseline liver function results is necessary during isotretinoin therapy due to the potential for hepatotoxicity. Regular monitoring helps ensure the liver is functioning properly. However, this information is secondary to the need to avoid pregnancy while on isotretinoin due to its severe teratogenic effects.

Choice D reason: Discontinuing isotretinoin one month before attempting to conceive is the most important information. Isotretinoin is highly teratogenic and can cause serious birth defects. It is crucial to stop the medication well before conception to ensure it is completely cleared from the body, reducing the risk of harm to the fetus.

Choice A reason:

Documenting the client’s refusal of the medication at this time is not the best response. While it is important to document any refusal of medication, the nurse should first educate the client on the proper administration of sucralfate. Sucralfate works by forming a protective barrier over ulcers, and it is most effective when taken on an empty stomach, at least 1 hour before meals.

Choice B reason:

Explaining the need to take the medication at least 1 hour before meals is the correct response. Sucralfate should be taken on an empty stomach to ensure it can effectively coat the stomach lining and protect it from acid. Taking it before meals maximizes its efficacy in treating and preventing ulcers.

Choice C reason:

Allowing the client to take the medication up to 1 hour after breakfast is not appropriate. Sucralfate needs to be taken on an empty stomach to form a protective barrier over the ulcer. Taking it after a meal would reduce its effectiveness, as the presence of food can interfere with its action.

Choice D reason:

Instructing the client to take it when the meal tray is delivered is incorrect. Sucralfate should be taken on an empty stomach, at least 1 hour before meals, to ensure it can properly coat the stomach lining and provide the necessary protection against stomach acid
