A nurse is preparing to administer hydrocortisone 60 mg IV bolus to a child. The amount available is hydrocortisone 100 mg powder. Reconstituting with 2 mL of bacteriostatic water yields hydrocortisone 50 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if applicable. Do not use a trailing zero.)
The Correct Answer is ["1.2"]
To calculate this, divide the dose of hydrocortisone in mg by the concentration of the reconstituted hydrocortisone to find the volume to administer: 60 mg / (50 mg/mL) = 1.2 mL.

Correct Answer is ["0.5"]
Explanation
Here's the detailed explanation: First, we need to convert the child's weight from pounds (lb) to kilograms (kg) since
the prescribed dose is in mg/kg/day.
There are approximately 2.2 lb in 1 kg, so the child's weight in kg is 55 lb / 2.2 = 25 kg. Next, we need to calculate the total daily dose of methimazole for the child.
The prescribed dose is 0.3 mg/kg/day, so the total daily dose is 25 kg * 0.3 mg/kg/day = 7.5 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: 7.5 mg/day / 3 = 2.5 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: 2.5 mg per dose / 5 mg per tablet = 0.5 tablets per dose.
Correct Answer is ["1"]
Explanation
To find out how many tablespoons of magnesium hydroxide the nurse should administer, we need to convert the volume from mL to tablespoons.
There are approximately 14.7868 mL in 1 tablespoon.
Therefore, to convert 15 mL to tablespoons, we divide 15 by 14.7868.
This gives us approximately 1.014 tablespoons. The answer is rounded to the nearest whole number as instructed.
