Collection ProceduresQuestion 15 of 100
A phlebotomist cleans the site with 70% isopropyl alcohol and inserts the needle immediately while the skin is still wet. What is the most likely result?
a.The specimen will clot faster in the tube
b.The venipuncture will be less painful for the patient
c.Stinging for the patient and hemolysis of the specimen
d.The antiseptic effect will be improved
Explanation
Alcohol must air dry for about 30 seconds so it can kill organisms and so residual alcohol is not carried into the vein. Wet alcohol stings on needle entry and lyses red cells, producing hemolysis that falsely raises potassium, LDH and AST. Drying is part of the antiseptic action, so puncturing early reduces rather than improves disinfection.
