In a client with HIV who is not consistently taking medications, which sign most strongly suggests an infection is present?

• A. Night sweats
• B. Persistent fever
• C. Creamy white patches on tongue
• D. Weight loss over several weeks

Answer: (D)

Fever is the body's systemic response to infection. In someone with HIV who isn’t consistently taking antiretroviral therapy, infections can take hold more readily and become more active, so a persistent fever signals that the body is actively fighting a pathogen. Among the options, this ongoing fever most strongly indicates an infection is present because it reflects a whole-body inflammatory response.

Night sweats can accompany fever but are less specific and can occur with other conditions. Creamy white patches on the tongue point to oral candidiasis, a localized opportunistic infection, not necessarily a systemic infection. Weight loss over weeks is a nonspecific finding that can result from several factors in HIV, including chronic disease, malnutrition, or prolonged illness, and does not by itself confirm an active infection. So persistent fever stands out as the clearest, most direct sign that an infection is currently present.
