A female client with mild depression reports to the nurse about recently starting St. John's wort. Which information provided by the client requires further instruction?

A. Insomnia may occur while taking the medication: St. John’s wort can cause side effects such as insomnia and restlessness, so the client’s report aligns with known reactions and requires no correction. B. Sensitivity to the sun can develop: Photosensitivity is a documented adverse effect of St. John’s wort, increasing the risk of sunburn; client awareness of this is appropriate and beneficial. C. Another form of contraception is not needed: St. John’s wort can reduce the effectiveness of hormonal contraceptives by inducing liver enzymes that metabolize these drugs faster, increasing the risk of unintended pregnancy. This requires correction and further instruction. D. Hard candy can be used for a dry mouth: Using hard candy to manage dry mouth is an acceptable supportive measure and does not conflict with medication use or safety.
