Most adults with human immunodeficiency virus will exhibit which of the following laboratory values?
Higherthannormal number of CD4+ Tcells and CD8+ Tcells are normal
Lowerthannormal number of CD4+ Tcells and CD8+ Tcells are normal
Lowerthannormal number of CD4+ Tcells and higher than normal CD8+ Tcells
Higherthannormal number of CD4+ Tcells and CD8+ Tcells are low
The Correct Answer is C
Choice A reason: Higherthannormal number of CD4+ Tcells and CD8+ Tcells are normal is not a laboratory value that most adults with human immunodeficiency virus will exhibit, because it does not reflect the effect of the virus on the immune system. CD4+ Tcells and CD8+ Tcells are types of white blood cells that play a key role in the immune response. CD4+ Tcells are helper cells that activate and coordinate other immune cells, while CD8+ Tcells are cytotoxic cells that kill infected or abnormal cells. Human immunodeficiency virus infects and destroys CD4+ Tcells, which impairs the immune function and increases the risk of opportunistic infections and cancers. CD8+ Tcells are not directly affected by the virus, but they may increase in number as a compensatory mechanism to fight the infection. Therefore, most adults with human immunodeficiency virus will have lowerthannormal number of CD4+ Tcells and higher than normal CD8+ Tcells.
Choice B reason: Lowerthannormal number of CD4+ Tcells and CD8+ Tcells are normal is not a laboratory value that most adults with human immunodeficiency virus will exhibit, because it does not reflect the effect of the virus on the immune system, as explained above. Lowerthannormal number of CD4+ Tcells and CD8+ Tcells are normal may indicate a condition that affects both types of Tcells, such as aplastic anemia, chemotherapy, radiation therapy, or immunosuppressive drugs.
Choice C reason: Lowerthannormal number of CD4+ Tcells and higher than normal CD8+ Tcells is a laboratory value that most adults with human immunodeficiency virus will exhibit, because it reflects the effect of the virus on the immune system, as explained above. Lowerthannormal number of CD4+ Tcells and higher than normal CD8+ Tcells may indicate the progression of the infection and the severity of the immunodeficiency. The normal range of CD4+ Tcells is 500 to 1500 cells per microliter of blood, while the normal range of CD8+ Tcells is 150 to 1000 cells per microliter of blood.
Choice D reason: Higherthannormal number of CD4+ Tcells and CD8+ Tcells are low is not a laboratory value that most adults with human immunodeficiency virus will exhibit, because it does not reflect the effect of the virus on the immune system, as explained above. Higherthannormal number of CD4+ Tcells and CD8+ Tcells are low may indicate a condition that affects CD8+ Tcells, such as leukemia, lymphoma, or corticosteroid therapy.

Correct Answer is A
Explanation
Choice A reason: Psoriasis is a skin abnormality that causes patches of thick, red skin with silvery scales, usually on the elbows, knees, scalp, lower back, or genitals. Psoriasis is a chronic, inflammatory, autoimmune condition that affects the life cycle of skin cells, causing them to build up rapidly on the surface of the skin. Psoriasis can cause itching, burning, pain, or bleeding.

Choice B reason: Rosacea is a skin abnormality that causes redness, flushing, swelling, or pimples, usually on the face, especially the cheeks, nose, chin, or forehead. Rosacea is a chronic, inflammatory, vascular condition that affects the blood vessels and sebaceous glands of the skin. Rosacea can cause sensitivity, stinging, or dryness.
Choice C reason: Scabies is a skin abnormality that causes small, red bumps, blisters, or burrows, usually on the hands, wrists, feet, ankles, or genitals. Scabies is a contagious, parasitic infection that is caused by tiny mites that burrow into the skin and lay eggs. Scabies can cause intense itching, especially at night.
Choice D reason: Stasis dermatitis is a skin abnormality that causes swelling, redness, scaling, or ulcers, usually on the lower legs or ankles. Stasis dermatitis is a chronic, inflammatory condition that results from poor blood circulation in the veins of the legs, causing fluid to leak into the surrounding tissues. Stasis dermatitis can cause pain, itching, or infection.
Correct Answer is A
Explanation
Choice A reason: Cleansing the skin around the pins is the action that the nurse takes first, because it is the most urgent and relevant action. Cleansing the skin around the pins is a procedure that involves removing any dirt, debris, or secretions from the pin sites, which can help prevent or treat infection, inflammation, or pain. Cleansing the skin around the pins is a priority intervention, as it can reduce the risk of complications, such as osteomyelitis, sepsis, or pin loosening.
Choice B reason: Collecting a culture of the purulent fluid is not the action that the nurse takes first, because it is not the most urgent and relevant action. Collecting a culture of the purulent fluid is a procedure that involves obtaining a sample of the pus from the pin sites and sending it to the laboratory for analysis, which can help identify the type and source of infection. Collecting a culture of the purulent fluid is an important intervention, but it should be done after cleansing the skin around the pins, and with a medical order and a sterile technique.
Choice C reason: Administering an antibiotic is not the action that the nurse takes first, because it is not the most urgent and relevant action. Administering an antibiotic is a procedure that involves giving the client an antimicrobial agent, which can help fight or prevent infection. Administering an antibiotic is an important intervention, but it should be done after cleansing the skin around the pins, and with a medical order and a proper route.
Choice D reason: Instructing the client to complete exercises of the affected extremity is not the action that the nurse takes first, because it is not the most urgent and relevant action. Instructing the client to complete exercises of the affected extremity is a procedure that involves teaching the client how to move and strengthen the muscles and joints of the limb in traction, which can help prevent or treat atrophy, contracture, or thrombosis. Instructing the client to complete exercises of the affected extremity is an important intervention, but it should be done after cleansing the skin around the pins, and with a medical order and a safe technique.
