While changing the dressing of a client who is immobile, the nurse notices the boundary of the wound has increased. Before reporting this finding to the healthcare provider, the nurse should evaluate which of the client's laboratory values?

Rationale: A. Neutrophil count: An elevated or decreased neutrophil count can indicate infection or impaired immune response, which may contribute to delayed wound healing and expansion of the wound boundary. Evaluating this value helps determine if infection is a contributing factor. B. Serum potassium and sodium levels: Electrolyte levels are important for overall cellular function but do not directly explain changes in wound size or healing progression. C. Platelet count: Platelets are essential for clotting, but an increase in wound size is more indicative of infection or tissue breakdown rather than a primary clotting problem. D. C-reactive protein level: CRP is an inflammatory marker that can indicate systemic inflammation, but neutrophil count provides more immediate information about the immune response related to infection at the wound site.
