A nurse is caring for a client who is coming to the clinic for human immunodeficiency virus (HIV) testing. The patient's enzyme-linked immunosorbent assay (ELISA) results are positive. Which test will be used to confirm the diagnosis of HIV?

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.

A. Fungal and bacterial infections can occur later as the immune system becomes compromised, but they are not initial symptoms of HIV infection.

B. Flu-like symptoms and night sweats are common initial manifestations of acute HIV infection, often occurring within 2-4 weeks after exposure.

C. Kaposi's sarcoma is a type of cancer associated with advanced HIV/AIDS and not an initial symptom of infection.

D. Pneumocystis lung infection typically occurs later in the course of HIV disease when the immune system is severely weakened, not during the initial infection stage.
