A nurse is changing the bed linen for a client who is on contact precautions. Which of the following personal protective equipment should the nurse wear?

A. Notifying the laboratory is not the first action to take in this situation. While it's important to inform the laboratory about suspected transfusion reactions for further investigation and documentation, immediate patient care takes precedence to ensure the client's safety.

B. This is the correct action to take first. Stopping the infusion of blood is crucial to prevent further administration of the potentially harmful blood product. Suspecting an acute hemolytic reaction (symptoms like chills, back pain, and hypotension) necessitates immediate cessation of the transfusion to minimize complications.
C. Obtaining a urine specimen may be indicated later to assess for hemolysis and kidney function, but it is not the first action to take. The priority is to stop the transfusion and assess the client's condition to manage the suspected transfusion reaction.
D. While it's important to notify the provider promptly, stopping the transfusion (option B) is the first critical action to take in response to suspected acute transfusion reactions. The provider will need to be informed for further orders and management, but immediate cessation of the transfusion is essential to prevent worsening of the client's condition.

A. The CD4-T-cell count is a critical indicator of immune function in individuals with HIV. CD4 cells are a type of white blood cell that HIV targets and destroys, leading to immune deficiency. A lower CD4 count indicates greater immunosuppression and increased susceptibility to opportunistic infections. Monitoring CD4 counts helps guide decisions regarding antiretroviral therapy (ART) initiation and monitoring response to treatment.
B. White blood cell (WBC) count measures the body's immune response and can fluctuate due to various factors. A WBC count of 5,000/mm3 is within the normal range, but it alone does not provide specific information about the client's HIV status or immune function compared to the CD4 count.
C. Platelets are involved in blood clotting, and a platelet count of 150,000/mm3 is within the normal range. Platelet counts are important for assessing bleeding risk but are not directly related to HIV progression or immune status.
D. A positive Western blot test confirms the presence of HIV antibodies in the blood. It is used for definitive HIV diagnosis after an initial positive screening test (such as ELISA). While important for diagnosis, once HIV is confirmed, ongoing monitoring of CD4 counts and viral load (not directly mentioned in the options) becomes more crucial for managing the disease.
