A nurse is caring for a client with HIV. Which laboratory test would be used to assess the effectiveness of therapy?
Viral load count
Western blot
Enzyme immunoassay (EIA) test
Platelet count
The Correct Answer is A
A. Viral load count is the primary test used to assess the effectiveness of HIV therapy by measuring the amount of HIV RNA in the blood, indicating how well the treatment is controlling the virus.
B. The Western blot is used as a confirmatory test for HIV diagnosis rather than monitoring therapy effectiveness.
C. The Enzyme immunoassay (EIA) test is used for initial HIV screening but does not measure viral load or therapy effectiveness.
D. Platelet count can be affected in HIV infection, especially with advanced disease, but it does not directly measure the effectiveness of HIV therapy.

Correct Answer is B
Explanation
A. A quantitative RNA assay is used to measure the amount of HIV RNA in the blood and is not used for confirmatory diagnosis after a positive ELISA.
B. The Western blot analysis is the standard confirmatory test for HIV following a positive ELISA result, as it specifically detects the presence of antibodies to HIV proteins.
C. A viral load test assesses the level of virus in the blood but does not confirm the diagnosis of HIV.
D. The CD4+ T-cell count is used to assess immune function in individuals with HIV but is not a confirmatory test for the diagnosis of the virus.
Correct Answer is ["B","C","D","E","F"]
Explanation
A. Hanging a bag of 0.9% normal saline with 5% dextrose (D5%NS) is incorrect; only normal saline (0.9% NS) should be used to prime the blood transfusion line to avoid hemolysis.
B. Verifying the client's name and blood type with a second nurse is a critical safety measure to prevent transfusion reactions and ensure the correct blood product is given.
C. Infusing the unit of blood within 4 hours is essential to reduce the risk of bacterial growth in the blood product.
D. Obtaining baseline vital signs prior to starting the transfusion is important to assess the client's condition and monitor for any changes during the transfusion.
E. Continuously monitoring the client during the first 15 minutes of the transfusion is vital for detecting any signs of a transfusion reaction promptly.
F. Inserting an 18-gauge intravenous catheter is recommended for blood transfusions as it provides a sufficient lumen to accommodate the blood flow.
G. Inserting a 22-gauge intravenous catheter is acceptable for some transfusions, but an 18-gauge is preferred for larger blood products.
