A nurse is preparing to administer ceftriaxone 50 mg/kg IM to a toddler who weighs 22 Ib. The amount available is ceftriaxone 350 mg/mL. How many mL should the nurse administer? (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 ceftriaxone: 50 mg/kg Weight of the toddler: 22 lb Concentration of ceftriaxone: 350 mg/mL Convert the toddler's weight from pounds to kilograms: 1 lb ≈ 0.453592 kg Calculate the total dose of ceftriaxone in mg: Total dose = Dose/kg x Weight (kg) Substitute the values: Total dose = 50 mg/kg x 22 lb x (0.453592 kg/1 lb) Total dose ≈ 498.95 mg Calculate the volume of ceftriaxone to be administered: Volume = Total dose (mg) / Concentration (mg/mL) Substitute the values: Volume = 498.95 mg / 350 mg/mL Volume ≈ 1.42 mL Round the answer to the nearest tenth: Volume ≈ 1.4 mL
