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? 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 stopper. 9. What class fire extinguisher would be appropriate to use on a fire in a chemical cabinet? a. Class A b. Class B c. Class C d. Class D 10. According to OSHA standards, laboratory coats must be all of the following except: a. Water resistant b. Made of cloth fabric that can be readily laundered c. Long-sleeved d. Worn fully buttoned 11. Which one of the following would NOT be part of a safety management plan? a. Job safety analysis b. Risk assessment of potential safety hazards c. Mechanism for reporting accidents d. Budget for engineering controls and personal protective equipment Chapter 3 Blood Specimen Collection 1. a; 2. b; 3. b; 4. c; 5. b; 6. b; 7. b; 8. d; 9. b; 10. c; 11. c; 12. a 1. Which step in the CLSI (Clinical & Laboratory Standards Institute) procedure for venipuncture is part of standard precautions? a. Wearing gloves b. Positively identifying the patient
