Question 1 of 5
A nurse is reviewing the laboratory results of a client who has a pressure ulcer. The nurse should identify an elevation in which of the following laboratory values as an indication that the client has developed an infection?
Correct Answer: B
Rationale: The correct answer is B: WBC count. An elevation in WBC count indicates an immune response to an infection. White blood cells increase to help combat pathogens. Potassium (
A), BUN (
C), and RBC count (
D) are not specific indicators of infection. Potassium levels can be affected by renal function, BUN reflects kidney function, and RBC count indicates oxygen-carrying capacity.
Therefore, an elevation in WBC count is the most relevant marker for infection in this scenario.
