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 aliquot for another department. She is wearing gloves
and 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 would you assess Mary's safety practice?
