Wound, Ostomy and Continence Nurses Society (WOCN) Practice Exam

Which symptom indicates the need for systemic antibiotic therapy?

1. Wound that is healing well

2. Increased white blood cell count

3. Presence of granulation tissue

4. Low-grade fever only

The correct answer is: Increased white blood cell count

An increased white blood cell count is a significant indicator that the body is responding to an infection. White blood cells are crucial components of the immune system, playing a vital role in identifying and combating infections. When there is an elevation in white blood cell count, it often suggests that the body is fighting off a potentially serious infection, necessitating further medical intervention. In the context of deciding whether systemic antibiotic therapy is required, an increased white blood cell count serves as a clear signal for healthcare professionals to evaluate the patient's condition closely. This might indicate that the infection has not been contained locally and could escalate if not treated promptly with appropriate antibiotics. Other symptoms listed, such as a wound that is healing well, the presence of granulation tissue, or a low-grade fever, do not typically warrant systemic antibiotic therapy. A healing wound indicates that the area is likely not infected; granulation tissue implies that the healing process is ongoing; and a low-grade fever may not always be a definitive sign of infection.
