What does the term "neutropenia" specifically refer to?

Neutropenia specifically refers to a low neutrophil count in the bloodstream. Neutrophils are a type of white blood cell that play a crucial role in the body’s immune response, particularly in fighting off infections. When a person's neutrophil count falls below normal levels, they may be at increased risk for infections, as their immune system is less able to respond effectively to pathogens. This condition can be caused by various factors, including bone marrow disorders, certain medications, autoimmune diseases, and chemotherapy. Understanding neutropenia is vital for nursing care, as it may influence patient management, infection prevention strategies, and the necessity for protective isolation measures in a clinical setting.
