What is true about antiretroviral drugs used to treat human immunodeficiency virus (HIV)?

Choice A reason: Blanching is not the term for black and necrotic tissue. Blanching is the temporary whitening of the skin when pressure is applied. It indicates that the blood flow is intact and the tissue is healthy.

Choice B reason: Cellulitis is not the term for black and necrotic tissue. Cellulitis is a bacterial infection of the skin and subcutaneous tissue. It causes redness, swelling, warmth, and pain in the affected area.

Choice C reason: Tunneling is not the term for black and necrotic tissue. Tunneling is a narrow channel or pathway that extends from the wound into the surrounding tissue. It indicates a deeper and more complex wound.

Choice D reason: Eschar is the term for black and necrotic tissue. Eschar is a thick, dry, and hard crust that forms over a wound. It indicates a severe tissue damage and impaired healing.

Choice A reason: These drugs kill the virus is not true about antiretroviral drugs used to treat human immunodeficiency virus (HIV), because it is inaccurate and misleading. Antiretroviral drugs do not kill the virus, but rather block or interfere with the enzymes or proteins that the virus needs to replicate or integrate into the host cells. Antiretroviral drugs can reduce the viral load, which is the amount of virus in the blood, but they cannot eliminate the virus completely.

Choice B reason: Only certain licensed drugs are effective is not true about antiretroviral drugs used to treat human immunodeficiency virus (HIV), because it is vague and incomplete. Antiretroviral drugs are licensed and approved by the regulatory authorities, such as the Food and Drug Administration (FDA), based on their safety and efficacy. However, not all licensed drugs are equally effective for all people with HIV, as the virus can develop resistance or mutation to some drugs over time. Therefore, the choice and combination of antiretroviral drugs may vary depending on the individual's viral genotype, drug history, and drug interactions.

Choice C reason: A few missed doses per month are OK is not true about antiretroviral drugs used to treat human immunodeficiency virus (HIV), because it is incorrect and dangerous. Antiretroviral drugs require strict adherence and compliance, which means taking the drugs exactly as prescribed, without missing or skipping any doses. A few missed doses per month are not OK, as they can reduce the effectiveness of the drugs and increase the risk of viral resistance or mutation, which can lead to treatment failure or disease progression.

Choice D reason: These drugs inhibit viral replication is true about antiretroviral drugs used to treat human immunodeficiency virus (HIV), because it describes the mechanism and outcome of the drugs. Antiretroviral drugs inhibit viral replication, which means they prevent or slow down the multiplication or reproduction of the virus. Antiretroviral drugs can inhibit viral replication by targeting different stages of the viral life cycle, such as reverse transcription, integration, or maturation. Antiretroviral drugs can improve the immune function and quality of life of people with HIV.
