Which test for HIV is used primarily as a confirmatory test rather than a generalized screening test?

Enzyme immunoassay.

Western Blot.

White blood cell differential.

CD4+ cell count.

Answer and Explanation

The Correct Answer is B

A. Enzyme immunoassay. The enzyme immunoassay (EIA), also known as the ELISA test, is used as a primary screening test for HIV. If the EIA test is positive, a confirmatory test, such as the Western Blot, is performed to ensure accuracy.

B. Western Blot. The Western Blot is a confirmatory test for HIV used to verify positive results from an initial screening test. It detects specific HIV antibodies and is highly specific, reducing the likelihood of false positives.

C. White blood cell differential. A white blood cell (WBC) differential assesses the overall immune response but does not diagnose HIV. While some HIV patients may show low WBC counts, this test is not specific for HIV infection.

D. CD4+ cell count. CD4+ cell count is used to monitor disease progression and immune function in HIV-positive patients, but it is not a confirmatory test for diagnosing HIV. A low CD4+ count suggests HIV progression toward AIDS rather than initial diagnosis.

Correct Answer is {"A":{"answers":"C"},"B":{"answers":"A"},"C":{"answers":"B"},"D":{"answers":"B"}}

Explanation

Instruct incentive spirometry use every hour (Nonessential): There is no indication of respiratory compromise, so incentive spirometry is not a priority for this client.

Encourage consumption of protein and vitamin C (Indicated): These nutrients support wound healing and immune function, which are important in managing infection and preventing further complications.

Apply thromboembolism deterrent stockings (TED) (Contraindicated): TED stockings may worsen symptoms if the client has cellulitis or a deep vein thrombosis (DVT), as compression can increase pain and impede circulation in an already swollen and inflamed limb.

Use petroleum-based lotion on legs (Contraindicated): Petroleum-based products can trap moisture and create an environment for bacterial growth, which is not suitable for a client with cellulitis or diabetes. Instead, a diabetic-safe moisturizer should be used while avoiding open wounds.

A. Dry mucosal membranes. B. Weight of 227 pounds (103 kg). C. Body mass index (BMI) of 17 kg/m2. D. Decrease in the appetite.

Correct Answer is C

Explanation

A. Dry mucosal membranes. While dry mucous membranes can indicate dehydration, they are not a definitive indicator of malnutrition. Malnutrition is assessed through body weight, BMI, and lab values such as albumin and prealbumin.
B. Weight of 227 pounds (103 kg). A high body weight does not indicate malnutrition. Some individuals with obesity can still be malnourished due to poor nutrient intake, but weight alone is not the best diagnostic indicator.
C. Body mass index (BMI) of 17 kg/m². A BMI below 18.5 kg/m² is classified as underweight, and a BMI of 17 kg/m² indicates malnutrition. BMI is a standard measure used to assess nutritional status and underweight conditions.
D. Decrease in the appetite. A decreased appetite (anorexia) can contribute to malnutrition, but it is a symptom, not a definitive diagnostic indicator. Some individuals with poor appetite may still maintain an adequate nutritional status.
