Which action helps prevent contamination when transferring medication from vial to syringe?

• A. Re-cap the needle before drawing
• B. Change the needle after the medication is drawn into the syringe
• C. Shake the vial vigorously
• D. Touch the needle with unwashed hands

Answer: (B)

Sterile technique during transferring medication from vial to syringe is about preventing any contaminants from entering the medication path. Changing the needle after drawing the dose ensures the syringe contains only sterile material when it's given to the patient. The needle used to puncture the vial stopper can pick up contamination; swapping it for a new sterile needle before administration minimizes the chance that contaminants are carried into the patient. Recapping before drawing, shaking vigorously, or touching the needle with unwashed hands all increase the risk of contamination or needle-stick injuries, so they are not appropriate practices.
