A nurse is preparing to administer megestrol 800 mg PO. Available is megestrol suspension 40 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

The nurse should administer 20 mL of megestrol suspension. Here's the calculation: Desired dose: 800 mg Concentration of available megestrol suspension: 40 mg/mL To find the volume to administer, we can divide the desired dose by the concentration and round to the nearest whole number: Volume to administer (rounded) = Dose / Concentration = 800 mg / (40 mg/mL) = 20 mL (rounded to nearest whole number) Therefore, the nurse should administer 20 mL of the megestrol suspension.
