It is primarily transmitted through casual contact.

It is primarily transmitted through mosquitoes.

It is primarily transmitted through direct contact with infected body fluids.

It is primarily transmitted through accidental puncture wounds.

Answer and Explanation

The Correct Answer is C

This is because HIV is a virus that infects certain cells of the immune system, such as CD4 cells or T cells. HIV can be found in blood, semen, vaginal fluid, breast milk, and other body fluids that contain blood. HIV can be transmitted through sexual contact, sharing needles or syringes, mother-to-child transmission during pregnancy or breastfeeding, or occupational exposure to blood or body fluids.

Correct Answer is B

Explanation

This is because Western blot analysis detects specific antibodies to HIV antigens and has a high specificity and sensitivity for HIV infection. CD4+ T-cell count measures the number of helper T cells in the blood and indicates the degree of immunosuppression in clients with HIV infection, but it does not confirm the diagnosis. Quantitative RNA assay and viral load test measure the amount of HIV RNA in the blood and indicate the level of viral replication and response to antiretroviral therapy, but they do not confirm the diagnosis.

A. Soles of the feet B. Ear lobes C. Oral mucosa D. Conjunctivae

Correct Answer is C

Explanation

This is because central cyanosis reflects a decrease in arterial oxygen saturation and is best seen in areas where blood vessels are close to the surface, such as the oral mucosa, tongue, and lips. Peripheral cyanosis, which may be caused by vasoconstriction or poor circulation, can be seen in the soles of the feet, ear lobes, and nail beds, but it does not necessarily indicate hypoxemia.
