A nurse is preparing to administer magnesium hydroxide 0.85 g PO to a school-age child. How many mg should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["850"]
Magnesium hydroxide is measured in grams (g) and milligrams (mg). There are 1000 milligrams in 1 gram. Therefore, to convert 0.85 g to mg, we multiply 0.85 by 1000. This gives us 850 mg. The answer is rounded to the nearest whole number as instructed.

Correct Answer is ["3.5"]
Explanation
First, we need to convert the child's weight from pounds to kilograms.
Since there are approximately 2.20462 pounds in 1 kilogram, 52 pounds is equivalent to 52/2.20462 =
23.587 kilograms.
The prescribed dose of digoxin is 7.5 mcg/kg/day, so for a child who weighs 23.587 kg, the total daily dose is 7.5 * 23.587 = 176.9 mcg/day.
Since the medication is available as a 50 mcg/mL elixir, the nurse should administer 176.9/50 = 3.538 mL/day.
Since the medication is to be administered once daily, the nurse should administer 3.5mL per dose. The answer is rounded to the nearest tenth as instructed.
