The healthcare provider (HCP) prescribes lorazepam 50 mcg/kg IM two hours before a scheduled procedure for a client who weighs 74 kg. The medication is available as "Lorazepam 2 mg/mL vial." How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)

Calculation: Calculate the prescribed dose in micrograms: Dose (mcg) = Prescribed dose (mcg/kg) x Client's weight (kg) = 50 mcg/kg x 74 kg = 3700 mcg Convert the dose from micrograms to milligrams: Dose (mg) = Dose (mcg) / 1000 mcg/mg = 3700 mcg / 1000 mcg/mg = 3.7 mg Calculate the volume to administer in mL: Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL) = 3.7 mg / 2 mg/mL = 1.85 mL Round to the nearest tenth: Rounded volume = 1.9 mL
