Step-by-step explanation:
The subject of this question is Health and the grade level is College. The question is related to Neutropenic Precautions in a client with acquired immunodeficiency syndrome (AIDS) with a CD4 cell count less than 200/microliter. Neutropenic precautions are measures taken to protect individuals with low white blood cell counts (neutrophils) from infections. In this case, the client's immunodeficiency makes them vulnerable to opportunistic infections, so it is important to take precautions to prevent the spread of infection and keep the environment clean and safe for the client.
