A nurse is preparing to administer carbamazepine suspension 150 mg via NG tube every 6 hr. The amount available is 100 mg/5 mL. How many mL should the nurse administer with each dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

To calculate the amount of carbamazepine suspension needed for each dose, you can use the following formula: (Dose required in mg / Concentration available in mg/mL) = Volume to administer in mL In this case: (150 mg / 100 mg/5 mL) = Volume to administer in mL (150 mg / 20 mg/mL) = 7.5 mL Therefore, the nurse should administer 7.5 mL of carbamazepine suspension via the NG tube for each dose.
