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

A) Breastfeeding is not recommended while taking this medication: While it’s important for clients to avoid breastfeeding while taking isotretinoin due to potential harm to the infant, the primary concern for a young adult female planning to become pregnant is the risk of teratogenic effects on the fetus. Therefore, while this information is relevant, it’s not the most important consideration in this situation.

B) Do not take multiple vitamins that contain vitamin A while taking this drug: Avoiding excessive intake of vitamin A is essential to prevent toxicity, but it’s not the most critical consideration for a client planning to become pregnant. The main concern is the teratogenic effects of isotretinoin on the fetus.

C) Baseline liver function results must be obtained during therapy: Monitoring liver function is important during isotretinoin therapy to assess for potential hepatotoxicity, but it’s not the most crucial consideration for a client planning to become pregnant. The primary concern is the need to discontinue the medication before conception to prevent fetal exposure.

D) Discontinue this medication one month before attempting to conceive: This is the most important information for the nurse to provide to the client. Isotretinoin is highly teratogenic and can cause severe birth defects if taken during pregnancy. Therefore, it’s essential for the client to discontinue isotretinoin at least one month before attempting to conceive to ensure the drug is cleared from the body and to prevent fetal exposure.

A) Notify the healthcare provider of the passage of black stools: This is the correct response. Black stools can indicate gastrointestinal bleeding, which is a serious adverse effect of NSAID use. It's im’ortant for the client to report this symptom promptly to the healthcare provider for further evaluation and management.

B) Call the clinic if diarrhea or headache occur when taking esomeprazole: While it's im’ortant to report any adverse effects of medication to the healthcare provider, diarrhea and headache are not specific to esomeprazole and may not warrant immediate attention unless severe or persistent.

C) Once pain subsides, NSAID therapy can be resumed: This statement is incorrect. The client should avoid NSAIDs in the future, as they are likely the cause of the gastric pain and gastrointestinal bleeding. Resuming NSAID therapy would increase the risk of recurrent bleeding.

D) Resume a diet that consists of milk, cream, and bland foods: This statement is incorrect. While bland foods may be easier to tolerate during acute gastric pain, they do not address the underlying issue of gastrointestinal bleeding. Additionally, dairy products like milk and cream may exacerbate symptoms in some individuals.
