Final answer:
Clients with HIV/AIDS should avoid raw fruits and vegetables, canned or frozen vegetables, and processed meat to manage gastrointestinal symptoms like diarrhea.
Step-by-step explanation:
Diarrhea can be a common symptom in clients with Human Immunodeficiency Syndrome (HIV/AIDS). In order to manage the gastrointestinal symptoms, the nurse should teach the client to avoid certain foods. The client should avoid raw fruits and vegetables because they can be a source of bacterial contamination. Additionally, the client should avoid canned or frozen vegetables as they may contain high levels of sodium, which can exacerbate the symptoms. Another food to avoid is processed meat because it can contain additives that may irritate the gastrointestinal system.
