Question

PMNs,polys,segs,and "shift to the left" are all terms that
A) refer to blood clots.
B) are related to erythrocytes.
C) are related to white blood cells.
D) indicate impending hemorrhage.

Accepted Answer

PMNs (polymorphonuclear leukocytes), polys, and segs are all names for different types of white blood cells (specifically, neutrophils). "Shift to the left" is a term used to describe an increase in immature white blood cells in the blood, which suggests that the body is trying to produce more white blood cells to fight an infection. None of these terms are specifically related to blood clots, erythrocytes, or impending hemorrhage.
