A nurse is preparing to administer enoxaparin 0.75 mg/kg subcutaneously to a client who weighs 69.9 kg (154 lb). The amount available is enoxaparin 60 mg/0.6 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Calculation: Calculate the total desired dose in mg: Desired dose (mg) = Weight (kg) x Ordered dose (mg/kg) Desired dose (mg) = 69.9 kg x 0.75 mg/kg Desired dose (mg) = 52.425 mg Determine the volume to administer using the available concentration: Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL) First, find the concentration in mg/mL: 60 mg / 0.6 mL = 100 mg/mL Now, calculate the volume: Volume to administer (mL) = 52.425 mg / 100 mg/mL Volume to administer (mL) = 0.52425 mL Round the answer to the nearest tenth: 0.52425 mL rounded to the nearest tenth is 0.5 mL.
