, 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

shield when opening the tube 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? a. Mary was careful and followed all appropriate
procedures. b. Mary should have used a shield when opening the
tube. c. Mary should have poured the sample into a sterile tube. d.
Mary should have wiped the tube with alcohol after replacing the
