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 a trailing zero.)

Calculation: Identify the prescribed dose and available concentration Ordered Dose: 40 mg Available Concentration: 100 mg/mL Calculate the volume to administer Volume to administer = Ordered Dose ÷ Concentration Volume to administer = 40 ÷ 100 Volume to administer = 0.4 mL Round to the nearest tenth = 0.4 mL
