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) Sensitivity to the sun can develop: St. John's wo’t can increase photosensitivity, making the skin more prone to sunburn. Therefore, clients should be advised to use sunscreen and protective clothing when exposed to sunlight. B) Hard candy can be used for a dry mouth: Dry mouth is a common side effect of St. John's wo’t. Suggesting the use of hard candy can help alleviate the discomfort associated with dry mouth by stimulating saliva production. C) Insomnia may occur while taking the medication: St. John's wo’t may cause insomnia or exacerbate existing sleep disturbances. Clients should be informed about this potential side effect so they can monitor their sleep patterns and seek appropriate management if needed. D) Another form of contraception is not needed: This statement requires further instruction. St. John's wo’t can decrease the effectiveness of hormonal contraceptives, including birth control pills, patches, and rings. Therefore, clients using hormonal contraceptives should be advised to use additional or alternative methods of contraception to prevent unintended pregnancy.
