A nurse is educating a group of individuals about HIV transmission. Which of the following modes of transmission is the main route for HIV to be passed from an infected person to an uninfected person?
Sharing injection equipment.
Mother-to-child transmission during pregnancy.
Unprotected sexual intercourse.
Occupational exposure to infected blood.
Blood transfusion from an infected donor.
The Correct Answer is C
Choice A rationale:
Sharing injection equipment can transmit HIV, but it is not the main route of transmission. This mode of transmission is more associated with other blood-borne infections like Hepatitis B and C.
Choice B rationale:
Mother-to-child transmission during pregnancy, childbirth, or breastfeeding can transmit HIV, but it is not the main route of transmission in the general population.
Choice C rationale:
Unprotected sexual intercourse is the main route for HIV transmission in the general population. Sexual contact with an infected person without using barrier methods like condoms can facilitate the spread of the virus.
Choice D rationale:
Occupational exposure to infected blood is a potential mode of transmission for healthcare workers, but it is not the main route of transmission for the general population.
Choice E rationale:
Blood transfusion from an infected donor was a significant mode of HIV transmission in the past, but extensive screening of blood donations has made this mode of transmission extremely rare.

Correct Answer is C
Explanation
Choice C rationale:
"Using condoms consistently and correctly during sexual intercourse can reduce the risk of HIV transmission." This statement is accurate and supported by scientific evidence. Condoms act as a barrier method and are effective in preventing the exchange of bodily fluids, thus reducing the likelihood of HIV transmission during sexual activity.
Choice A rationale:
"You should avoid getting tested for HIV regularly." This statement is incorrect and potentially harmful. Regular HIV testing is essential for early detection and timely initiation of treatment if needed. Early diagnosis improves health outcomes and reduces the risk of transmitting the virus to others.
Choice B rationale:
"Pre-exposure prophylaxis (PrEP) is used after HIV exposure." This statement is incorrect. PrEP is taken before potential HIV exposure to prevent infection. It involves taking antiretroviral medications regularly to reduce the risk of acquiring the virus.
Choice D rationale:
"Supervised injection facilities aim to increase risky behaviors among drug users." This statement is incorrect. Supervised injection facilities provide a safe and controlled environment for drug users to consume drugs under medical supervision, reducing the risk of overdose and the transmission of infectious diseases like HIV and hepatitis
C.
Correct Answer is B
Explanation
Choice A rationale:
Antiretroviral therapy (ART) can help increase CD4 count, but the primary goal of ART is to suppress viral replication and reduce viral load to undetectable levels, thereby preserving immune function.
Choice B rationale:
This is the correct answer. The goal of antiretroviral therapy (ART) is to reduce viral load to undetectable levels, which helps in preventing disease progression and transmission of HIV.
Choice C rationale:
Preventing opportunistic infections and cancers is an important benefit of ART, but the primary goal is to suppress viral replication.
Choice D rationale:
Adherence to the prescribed regimen and schedule is crucial for the effectiveness of ART, but it is not the primary goal of ART itself.
