113. A 10-month-old girl develops a cough and grunting following a 3-day hospital stay for surgical repair of a cleft palate. Her temperature is 39.2°C (102.6°F), and respirations are 40/min. Crackles are heard over most lung fields, and breath sounds are decreased. There is a mild pleural rub in the right upper thorax. Her leukocyte count is 68,000/mm³ (85% segmented neutrophils, 10% bands, and less than 5% myeloblasts, promyelocytes, and myelocytes). Which of the following mechanisms most likely caused the increased leukocyte count in this patient? A) Accelerated release of cells from the bone marrow postmitotic reserve pool B) Decreased margination and rolling of circulating cells C) Increased production of myeloblasts in the spleen D) Shift in bone marrow from eosinophil production to segmented neutrophil production E) Transformation of myeloid stem cells
