Calculation
A nurse is preparing to administer methylphenidate oral solution 25 mg to a school-age child. The amount available is methylphenidate oral solution 10 mg/5 mL. How many mL should the nurse plan to administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
mL
Explanation & Rationale
Calculation: Desired dose = 25 mg. Available concentration = 10 mg / 5 mL. Calculate the volume to administer. Volume (mL) = Desired dose (mg) / Available concentration (mg/mL) = 25 mg / (10 mg / 5 mL) = 25 mg × (5 mL / 10 mg) = (25 × 5) / 10 mL = 125 / 10 mL = 12.5 mL
