While changing a client's postoperative dressing, the nurse observes purulent drainage at the site. Before reporting this finding to the healthcare provider, the nurse should note which of the client's laboratory values?

A. While a platelet count is important for assessing bleeding risk, it does not directly indicate infection or the body's inflammatory response. B. Hematocrit levels provide insight into the client's blood volume and hydration status but are not specifically indicative of infection. C. The neutrophil count is crucial to evaluate, as neutrophils are key components of the immune response to infection. An elevated neutrophil count may suggest a bacterial infection, making it essential to assess before reporting purulent drainage. D. Serum sodium level is not directly related to infection assessment and would not be a priority in this context.
