barrel to inject air equal to the amount of medication to be withdrawn. With the vial

(c) Withdraw the needle from the container. Care should be taken not
to separate the needle and syringe while withdrawing the needle.

eye level and ensuring the forward edge of the plunger is at the desired level
(prescribed dosage plus about 0.2 cc). Verify the correct dosage with the written order.
(e) Place the protective cover on the needle.
