A patient has an order to receive 0.3 mL of U-500 insulin. Which syringe will the nurse obtain to administer the medication?

A) 3-mL syringe
B) U-100 syringe
C) Needleless syringe
D) Tuberculin syringe

Because there is no syringe currently designed to prepare U-500 insulin, many medication errors result with this kind of insulin. To prevent errors, ensure that the order for U-500 specifies units and volume (e.g., 150 units, 0.3 mL of U-500 insulin), and use tuberculin syringes to draw up the doses. A 3 mL and U-100 can result in inaccurate dosing. A needleless syringe will not be acceptable in this situation.
