Final answer:
The nurse should inform the client to apply sunblock and recommend taking chlorpromazine on an empty stomach to counteract the adverse effects of the medication.
Step-by-step explanation:
When caring for a client taking chlorpromazine, the nurse should take the following action to counteract the adverse effects of the medication:
- Inform the client to apply sunblock before going outside. Chlorpromazine can cause photosensitivity, which can lead to severe sunburn or rash when exposed to sunlight. Applying sunblock can help protect the skin from these adverse effects.
- Recommend that the client take the medication on an empty stomach. Taking chlorpromazine with food can decrease its absorption and effectiveness. Taking it on an empty stomach can help ensure optimal absorption and therapeutic effects.
