Your response:
Let the alcohol air dry before inserting the needle
Correct response:
Let the alcohol air dry before inserting the needle
Rationale: Proper preparation for venipuncture requires that the site be cleansed (70% isopropyl
alcohol or other antiseptic agent as indicated by the manufacturer’s instructions). Human skin
harbors normal flora (bacteria that naturally lives on the surface of the skin). To prevent
introduction of said bacteria into the patient or the blood samples, the phlebotomist should apply
the antiseptic to the venipuncture site (in concentric circles to avoid contaminating cleansed
areas with the antiseptic applicator). The antiseptic should be allowed to air dry, allowing ample
time for the antiseptic action to take effect. Residual (undried) alcohol could lead to hemolysis
of the specimen and could create a burning sensation for the patient upon needle insertion.
