Final answer:
When developing a teaching plan for a patient diagnosed with HIV, the nurse should educate the patient about the benefits and risks of alternative or complementary therapies and inquire about any specific therapies the patient follows or herbs and supplements they take.
Step-by-step explanation:
When developing a teaching plan for a patient diagnosed with HIV, the nurse should provide information about alternative or complementary therapies. The nurse should not discourage the patient from exploring these therapies (option a) but instead educate the patient about their benefits and risks (option c). It is important to ask the patient if they follow any specific alternative or complementary therapies or if they take any herbs or supplements.
