It is a busy evening in the City Hospital hematology
department. One staff member called in sick, and there
was a major auto accident that has one staff member tied
up in the blood bank all evening. Mary, the medical
laboratory scientist covering hematology, is in a hurry to
get a stat sample on the analyzer but needs to pour off an

a lab coat. She carefully covers the stopper of the well-
mixed ethylenediaminetetraacetic acid (EDTA) tube with a
gauze square and tilts the stopper toward her so it opens
away from her. She pours off about 1 mL into a prelabeled
tube, replaces the stopper of the EDTA tube, and puts it in
the sample rack and sets it on the conveyor. She then
brings the poured sample off to the other department. How
