A nurse is preparing to administer furosemide 1 mg/kg IV bolus to a preschooler who weighs 36 lb. Available is furosemide injection 10 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if applicable. Do not use a trailing zero.)
The Correct Answer is ["1.6"]
To calculate this, first convert the preschooler's weight from pounds to kilograms: 36 lb * (1 kg / 2.2 lb) = 16.36 kg.
Then, calculate the dose of furosemide in mg: 1 mg/kg * 16.36 kg = 16.36 mg.
Finally, divide the dose in mg by the concentration of the furosemide injection to find the volume to administer: 16.36 mg / (10 mg/mL) = 1.636 mL/dose, which rounds to 1.6 mL when rounded to the nearest tenth.

Correct Answer is ["30"]
Explanation
To calculate this, first convert the child's weight from pounds to kilograms: 66 lb * (1 kg / 2.2 lb) = 30 kg. Then, calculate the total daily dose of dexamethasone in mg: 0.2 mg/kg/day * 30 kg/day = 6 mg/day.
Since the daily dose is divided into two doses, calculate the dose per administration: 6 mg/day / 2 doses/day = 3 mg/dose.
Finally, divide the dose in mg by the concentration of the dexamethasone elixir to find the volume to administer: 3 mg / (0.5 mg/5 mL) = 30 mL/dose.
Correct Answer is ["1.1"]
Explanation
First, we need to calculate the total daily dose of methimazole for the child.
The child weighs 55 kg and the prescribed dose is 0.3 mg/kg/day, so the total daily dose is 55 kg * 0.3 mg/kg/day = 16.5 mg/day.
Since the medication is to be divided into equal doses every 8 hours, we need to divide the total daily dose by 3 to get the dose per administration: 16.5 mg/day / 3 = 5.5 mg per dose.
Finally, since each tablet contains 5 mg of methimazole, we need to divide the dose per administration by the amount of medication per tablet: 5.5 mg per dose / 5 mg per tablet = 1.1 tablets per dose.
