A female client with mild depression reports to the nurse of recently starting St. John's wo’t. Which information provided by the client requires further instruction?

A) Increased frequency of lacrimation is not typically associated with miotic therapy. Miotics work by constricting the pupil and increasing outflow of aqueous humor to reduce intraocular pressure, but they do not directly affect lacrimation (tear production). Therefore, this option is not the etiology for the “Risk for injury” nursing problem.

B) Decreased night vision is a common side effect of miotic therapy. Miotics constrict the pupil, which can reduce the amount of light entering the eye, leading to impaired night vision or difficulty seeing in low-light conditions. This impaired vision increases the risk of injury, particularly in situations with reduced lighting.

C) Increased sensitivity to light (photophobia) is not typically associated with miotic therapy. Miotics constrict the pupil, which may actually reduce sensitivity to light by decreasing the amount of light entering the eye. Therefore, increased sensitivity to light is not the etiology for the “Risk for injury” nursing problem in this case.

D) Diminished color perception is not a common side effect of miotic therapy. Miotics primarily affect pupil constriction and intraocular pressure but do not typically alter color perception. Therefore, diminished color perception is not the etiology for the “Risk for injury” nursing problem.

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.
