What is the primary reason for monitoring WBC count in a client with immunosuppression?

Monitoring the white blood cell (WBC) count in a client with immunosuppression is primarily important for preventing infection. In individuals who are immunosuppressed, whether due to underlying medical conditions, medications, or treatments like chemotherapy, the body's ability to fight off infections is significantly compromised. A low WBC count, particularly a decreased neutrophil count (neutropenia), indicates a higher risk of infection since neutrophils play a key role in the immune response against pathogens.

By regularly checking the WBC count, healthcare providers can assess the immune status of the patient. If the WBC count drops below a certain threshold, it serves as an alert for the healthcare team to implement preventative measures, such as initiating prophylactic antibiotics, implementing strict infection control measures, or adjusting immunosuppressive therapies. This proactive approach significantly reduces the risk of serious infections, which can be life-threatening for immunocompromised individuals.
