Calculation
The healthcare provider prescribes enoxaparin 1 mg/kg SUBQ every 12 hours for a client who weighs 132 pounds. The medication is available in "Enoxaparin 60 mg/0.6 mL prefilled syringe." How many mL should the nurse administer per day? (Enter numerical value only.)
mL
Explanation & Rationale
Convert the client's weight from pounds to kilograms: Weight (kg) = Weight (pounds) / 2.2 pounds/kg = 132 pounds / 2.2 pounds/kg = 60 kg Calculate the dose per administration: Dose per administration (mg) = Prescribed dose (mg/kg) x Client's weight (kg) = 1 mg/kg x 60 kg = 60 mg Determine the volume to administer per dose: Volume per dose (mL) = Desired dose (mg) / Available concentration (mg/mL) = 60 mg / (60 mg / 0.6 mL) = 0.6 mL Calculate the total volume to administer per day: Number of administrations per day = every 12 hours means 24 hours / 12 hours/administration = 2 administrations Total daily volume (mL) = Volume per dose (mL) x Number of administrations per day = 0.6 mL/dose x 2 doses/day = 1.2 mL/day
