A client who weighs 132 lb receives a prescription for lorazepam 44 mcg/kg IV to be administer 20 minutes before a scheduled procedure. The medication is available in 2 mg/mL vial. How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)

To calculate the dosage of lorazepam for the client, first convert the client's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The client weighs 132 lb, which is approximately 60 kg (132 lb / 2.2 lb/kg). Next, multiply the client's weight in kilograms by the prescribed dose of 44 mcg/kg. This results in a total dose of 2640 mcg (60 kg x 44 mcg/kg). Since the medication is available in a concentration of 2 mg/mL, convert the total dose needed into milligrams (2640 mcg is equal to 2.64 mg). Finally, divide the total dose in milligrams by the concentration of the medication to find out how many mL to administer: 2.64 mg divided by 2 mg/mL equals 1.32 mL. After rounding to the nearest tenth, the nurse should administer 1.3 mL of lorazepam.
