A.

Left Shift

B.

Leukocytosis

C.

Neutropenia

D.

Leukopenia

Answer and Explanation

The Correct Answer is B

A.    Left Shift: This term refers to an increased number of immature neutrophils (bands) and is typically seen in bacterial infections but does not solely describe the high WBC count.
B.    Leukocytosis: This term refers to an elevated WBC count above the normal range (typically >11,000/mm³) and may indicate infection, inflammation, or other conditions.
C.    Neutropenia: Neutropenia refers to a decrease in neutrophils, not an elevated WBC count.
D.    Leukopenia: Leukopenia is a decrease in WBC count, opposite of leukocytosis.
