g. Check Medication for Defects.
(1) If there are any foreign particles in the solution or if there is any change

(1) Cleanse the stopper with an alcohol sponge. You should leave the
sponge on the stopper at least 30 seconds.

remove the needle cover. Pull the plunger out and fill the syringe with air equal to the
amount of medication ordered.
(3) With the free hand, pick up and invert the vial, and then insert the needle
into the rubber stopper. Make certain the needle tip passes completely through the cap
(see figure 1-7). When inserting the needle, the bevel should face up with a slight
pressure being exerted down and forward against the needle to prevent rubber from
contaminating medication. To avoid contaminating the needle, the hub of the needle
should not touch the rubber cap.
