A nurse is preparing to administer furosemide 2 mg/kg/day IV bolus divided in equal doses every 8 hr to a toddler who weighs 22 lb. Available is furosemide injection 5 mg/mL. how many mL should the nurse administer per dose? (Round the answer to the nearest tenth.)
Correct answer
1.3
Rationale
To calculate the dose of furosemide, first convert the toddler's weight from lb to kg: 22 lb ├À 2.2 = 10 kg. Then, calculate the total daily dose: 2 mg/kg/day x 10 kg = 20 mg/day. Since the dose is divided into equal doses every 8 hours, divide the total daily dose by 3 (24 hours ├À 8 hours) to get the dose per administration: 20 mg/day ├À 3 = 6.67 mg/dose. To convert this to mL, divide by the concentration of the injection: 6.67 mg ├À 5 mg/mL = 1.334 mL, rounded to 1.3 mL. Therefore, the correct answer is 1.3 mL per dose.
