A 31-year-old male patient complains of fatigue, yeast infection in his mouth, and enlarged lymph nodes under his arms. He said that he was involved in “high-risk” behavior 6 years ago while on a trip to eastern and southern Africa. He also indicated that his “HIV test” was negative. Which one of the following options would be most appropriate?

**Core Concept**
The patient's symptoms, such as fatigue, oral yeast infection, and enlarged lymph nodes, suggest a compromised immune system, potentially indicating an HIV infection. The patient's history of "high-risk" behavior and travel to eastern and southern Africa, regions with high HIV prevalence, further supports this suspicion.

**Why the Correct Answer is Right**
Although the patient's "HIV test" was negative, this does not rule out HIV infection, especially if the test was conducted during the window period or if it was a false negative. The most appropriate next step would be to conduct further testing, considering the patient's symptoms and risk factors.

**Why Each Wrong Option is Incorrect**
**Option A:** This choice is incorrect because it does not address the patient's potential HIV status or the need for further testing.
**Option B:** Similarly, this option is incorrect as it does not consider the patient's symptoms or risk factors.
**Option C:** This choice is also incorrect because, without knowing the type of HIV test conducted or when it was done, simply accepting a negative result may miss an early infection.
**Option D:** This option is incorrect as it is not provided.

**Clinical Pearl / High-Yield Fact**
It's crucial to remember that HIV tests, especially rapid tests or those done early after exposure, can yield false negatives. A combination of clinical judgment, risk assessment, and possibly repeat or different types of HIV tests (like RNA tests) may be necessary for accurate diagnosis.

**Correct Answer:** D. Repeat HIV testing and consider viral load measurement.

✓ Correct Answer: D. Order an HIV test which would include antibodies to HIV-1 and HIV-2
