A nurse is reviewing the laboratory report of a client who is receiving treatment for a high fever and a viral infection. Which of the following findings should the nurse expect?

A. T-cell counts may fluctuate during viral infections but are not the primary laboratory change expected in acute bacterial response. B. A “left shift” indicates an increased number of immature neutrophils (bands), which is a typical response to infection and inflammation, especially bacterial infections. C. Hemoglobin levels are not directly affected by acute viral infections or fever. D. Leukocyte count usually increases (leukocytosis) rather than decreases in response to infection.
