Which sign should a nurse report when caring for the patient with AIDS who has cutaneous Kaposi sarcoma?

A. Weight loss: Weight loss is common in AIDS (wasting syndrome) and is generally expected in advanced stages. B. Abdominal pain: While Kaposi sarcoma (KS) often appears on the skin, it can also occur internally (visceral KS). Abdominal pain can indicate KS lesions in the gastrointestinal tract, which can lead to life-threatening bleeding or obstruction. C. Fatigue: Fatigue is a universal symptom in AIDS and chronic illness and does not specifically signal a new complication of Kaposi sarcoma. D. Nausea: Nausea is common due to many AIDS-related medications and infections; it is less specific to a KS complication than localized abdominal pain.
