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.) ________ mL

Step 1 is to identify the ordered dose and the available concentration Ordered Dose: 40 mg Available Concentration: 100 mg / 1 mL Step 2 is to calculate the volume to administer in milliliters (mL) Volume = (Ordered Dose ÷ Available Dose) × Available Volume Volume = (40 ÷ 100) × 1 40 ÷ 100 = 0.4 0.4 × 1 = 0.4 Step 3 is to round to the nearest tenth 0.4 = 0.4 Answer: 0.4
