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 Correct Answer is ["20 "]
Given:
- Desired dose of megestrol: 800 mg
- Available strength of megestrol suspension: 40 mg/mL
First, find out how many milliliters of megestrol suspension correspond to the desired dose: Volume (mL) = Desired dose / Concentration
Volume (mL) = 800 mg / 40 mg/mL Volume (mL) = 20 mL
So, the nurse should administer 20 mL of megestrol suspension.
