A client is to receive enoxaparin 30 mg subcutaneously. Available is enoxaparin 40 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: Desired dose = 30 mg. Available concentration = 40 mg/mL. Calculate the volume to administer in milliliters (mL). Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL) = 30 mg / 40 mg/mL = 0.75 mL. Round to the nearest tenth. = 0.8 mL.
