When the nurse discontinues a 24-hour postoperative client's patient-controlled analgesia (PCA) pump, the client asks to go to the hospital's smoking area to smoke a cigarette. Which response should the nurse provide?

Choice A reason: Advising the client to wait at least one hour before leaving the unit may not address the underlying health risks associated with smoking, especially after surgery. It does not provide sufficient health education about the dangers of smoking.

Choice B reason: Allowing the client to smoke in their room is inappropriate and unsafe. Smoking indoors poses fire hazards and exposes others to secondhand smoke, which is harmful. This response is not acceptable in a healthcare setting.

Choice C reason: This response addresses the health risks of smoking and provides sound advice for postoperative care. Educating the client about the dangers of smoking, especially after surgery, is crucial for their recovery and overall health.

Choice D reason: Allowing the client to go to the smoking area in a wheelchair does not address the health risks associated with smoking, especially after surgery. This response is not appropriate for promoting the client's health and recovery.

Choice A reason: Using hard candy to alleviate dry mouth is a common suggestion for clients experiencing dry mouth as a side effect of medications, including herbal supplements like St. John's wort. This information does not require further instruction as it is a helpful and safe practice.

Choice B reason: Insomnia can occur while taking St. John's wort due to its stimulating effects. Clients should be informed about this potential side effect and how to manage it, but this information does not require further instruction as it is accurate and relevant.

Choice C reason: Sensitivity to the sun is a known side effect of St. John's wort. Clients should be advised to use sun protection and avoid excessive sun exposure. This information is correct and does not require further instruction.

Choice D reason: The statement that another form of contraception is not needed requires further instruction because St. John's wort can interact with hormonal contraceptives, potentially reducing their effectiveness. Clients should be advised to use an additional form of contraception to prevent unintended pregnancy.
