The nurse is reviewing laboratory results for a patient who has HIV. Which result would be strongly suggestive of a diagnosis of AIDS?
Correct Answer: A
Rationale: The correct answer is A because a CD4+ count of 180/μL is significantly below the normal range (500-1500/μL) and indicative of severe immunosuppression, which is a hallmark of AIDS. CD4+ percentage alone (choice B) may not provide the full picture. CD8+ count (choice C) doesn't directly indicate immune system status in HIV/AIDS. The CD4+/CD8+ ratio (choice D) may be altered in various conditions, not specific to AIDS.
