The nurse is preparing to administer enoxaparin 90 mg SUBQ daily to a client admitted with a pulmonary embolism. The pharmacy provides a prefilled syringe labeled, “Enoxaparin 100 mg/1 mL.” How many mL should the nurse administer? (Enter numeric value only.)

Calculation: Identify the desired dose: Desired dose = 90 mg Identify the available concentration: Available concentration = 100 mg / 1 mL Calculate the volume to administer: Volume (mL) = Desired dose (mg) / Available concentration (mg/mL) = 90 mg / 100 mg/mL = 0.9 mL
