A nurse is reviewing the diagnostic tests used for HIV infection with a client. The nurse explains that nucleic acid tests (NAT) have the shortest window period after exposure, detecting HIV infection as early as:.
3-12 weeks.
2-6 weeks.
10-33 days.
6 months.
The Correct Answer is B
Choice A rationale:
Nucleic acid tests (NAT) are highly sensitive tests that can detect HIV infection early, but the window period stated (3-12 weeks) is not accurate. NAT can detect HIV RNA as early as 9-11 days after exposure, but it may take up to 2-6 weeks for it to be reliably detected.
Choice B rationale:
This is the correct answer. Nucleic acid tests (NAT) can detect HIV infection as early as 2-6 weeks after exposure, making it the option with the shortest window period.
Choice C rationale:
This option is incorrect. NAT can detect HIV infection earlier than the time range stated (10-33 days)
Choice D rationale:
This option is incorrect. NAT can detect HIV infection much earlier than 6 months after exposure.

Correct Answer is D
Explanation
Choice A rationale:
This statement is inaccurate. HIV is not an acute infection that resolves without treatment. It is a chronic condition that persists in the body, and without treatment, it can progress to AIDS, which can be life-threatening.
Choice B rationale:
This statement is also inaccurate. While Antiretroviral Therapy (ART) is highly effective in controlling HIV and improving the quality of life for people living with the virus, it is not a curative treatment. HIV remains in the body, and stopping ART can lead to viral rebound.
Choice C rationale:
This statement is incorrect. HIV testing is essential, even in the absence of visible symptoms. Many individuals with HIV may not show any symptoms for years, but early detection through testing allows for timely intervention and better disease management.
Choice D rationale:
This is the correct statement. HIV is primarily transmitted through contact with infected body fluids, such as blood, semen, vaginal fluids, and breast milk. Common modes of transmission include unprotected sexual intercourse, sharing of contaminated needles, and from mother to child during childbirth or breastfeeding.
Correct Answer is C
Explanation
Choice A:
Needle exchange programs and Choice C:
Infection prevention education.
Choice A rationale:
Needle exchange programs are essential in minimizing the negative consequences of drug use, especially for patients with HIV. These programs provide clean needles and syringes, reducing the risk of transmitting the virus through contaminated equipment.
Choice C rationale:
Infection prevention education is crucial for patients with HIV who engage in drug use. Educating them about safe practices and harm reduction strategies can help reduce the risk of spreading infections and improve overall health outcomes.
Choice B rationale:
Post-exposure prophylaxis (PEP) is not relevant to this situation. PEP is a preventive treatment given after potential exposure to HIV, not a strategy to minimize the consequences of ongoing drug use.
Choice D rationale:
Male circumcision has been shown to reduce the risk of HIV transmission in heterosexual men. However, it is not a strategy to minimize the negative consequences of drug use, and its relevance is not applicable to this question.
