While caring for a client with a full thickness burn covering 40% of the body, the nurse observes purulent drainage at the wound. Before reporting this finding to the healthcare provider, the nurse should review which of the client's laboratory values?

A. Reviewing the white blood cell (WBC) count is important because purulent drainage suggests infection, and an elevated WBC count may indicate an inflammatory response to infection.B. Hematocrit is an important parameter to monitor but may not directly indicate the presence of infection associated with purulent drainage in a burn wound.C. Blood pH level is an important parameter to monitor but may not directly indicate the presence of infection associated with purulent drainage in a burn wound.D. Platelet count is an important parameter to monitor but may not directly indicate the presence of infection associated with purulent drainage in a burn wound.
