A nurse is preparing to administer ferrous fumarate 3 mg/kg PO 3 times a day to a toddler who weighs 22 lb. Available is ferrous fumarate drops 45 mg/0.6 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Identify the given information: Dose of ferrous fumarate: 3 mg/kg/day Weight of the toddler: 22 lb Concentration of ferrous fumarate drops: 45 mg/0.6 mL Convert the toddler's weight from pounds to kilograms: 1 lb ≈ 0.453592 kg Calculate the total daily dose of ferrous fumarate in mg: Total daily dose = Dose/kg/day x Weight (kg) Substitute the values: Total daily dose = 3 mg/kg/day x 22 lb x (0.453592 kg/1 lb) Total daily dose ≈ 29.97 mg Calculate the dose per dose (every 8 hours): Dose per dose = Total daily dose / 3 Substitute the values: Dose per dose = 29.97 mg / 3 Dose per dose ≈ 9.99 mg Calculate the volume of ferrous fumarate drops to be administered: Volume = Dose per dose (mg) / Concentration (mg/mL) Substitute the values: Volume = 9.99 mg / (45 mg/0.6 mL) Volume ≈ 0.133 mL Round the answer to the nearest tenth: Volume ≈ 0.1 mL
