Which practice is appropriate when preparing a vial for drawing medication?

• A. Attach the needle firmly to the syringe
• B. Rub vigorously back and forth over the rubber cap with alcohol
• C. Inject air into the vial
• D. Draw up slightly more air than the volume to withdraw

Answer: (A)

Attaching the needle securely to the syringe is essential because it creates a stable, sterile setup for drawing medication. A firm connection prevents the needle from loosening or detaching during aspiration, which reduces the risk of contamination, medication loss, or accidental needle sticks. After that, the vial stopper should be cleaned with an antiseptic wipe using a single motion and allowed to dry; vigorous rubbing is not needed and can contaminate the stopper. Regarding air, the aim is to introduce enough air to equalize pressure for smooth withdrawal, typically equal to the dose being drawn (not more). Drawing up extra air can complicate dosing and increase the chance of air entering the syringe.
