A nurse is preparing to administer enoxaparin 40 mg subcutaneous for prevention of deep-vein thrombosis. Available is enoxaparin 100 mg/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 trailing zero.)

Determine the total daily dosage: The client is prescribed 40 mg of enoxaparin. Calculate the dosage per dose: The medication is to be administered in a single dose. Dosage per dose is 40 mg. Determine the volume per dose: The enoxaparin solution contains 100 mg per mL. The nurse needs to administer 40 mg per dose. Divide 40 mg / 100 mg per mL = 0.4 mL per dose.
