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

Choice A rationale: Serum blood glucose (BG) level is not directly related to the presence of purulent drainage at a burn wound site. Elevated BG levels might be seen in clients with diabetes or as a stress response, but they are not the primary indicator of infection or wound complications. Choice C rationale: Serum albumin levels can be relevant in assessing nutritional status and the body's ability to heal wounds. However, they do not directly indicate the presence of infection or purulent drainage. Low serum albumin levels may be seen in clients with malnutrition but do not provide immediate information about the wound. Choice D rationale: Hematocrit measures the percentage of red blood cells in the blood and is not directly related to the presence of purulent drainage at a burn wound site. Elevated hematocrit may indicate dehydration or hemoconcentration but does not specifically address the issue of wound infection.
