The practical nurse (PN) is preparing the prescribed dose of diazepam 5 mg IM STAT for a client in delirium tremens. The available concentration is 10 mg/2mL. How many milliliters should the PM administer to the client? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Identify the prescribed dose and the available concentration. Prescribed dose = 5 mg Available concentration = 10 mg per 2 mL Calculate the volume in milliliters (mL) to administer. Volume (mL) = (Prescribed dose (mg) / Available concentration (mg)) x Available volume (mL) = (5 mg / 10 mg) x 2 mL = 0.5 x 2 mL = 1.0 mL.
