A client has an order for 150 mg of cimetidine IM. The vial contains 300 mg/2 mL. How many milliliters should be administered?

Explanation:
To determine the right amount to inject, use the vial’s concentration to convert milligrams into milliliters. The vial has 300 mg in 2 mL, which means the solution contains 150 mg per milliliter. The ordered dose is 150 mg, so the required volume is 150 mg ÷ (150 mg/mL) = 1 mL. Therefore, administer 1 milliliter.
