Full Explanation
To find out how many mL/hr the IV pump should be set to deliver, we need to divide the total volume of the infusion by the infusion time in hours.
If 1,000 mL of 0.45% sodium chloride is to be infused over 8 hours, then the rate of infusion is 1,000/8 = 125 mL/hr.
The answer is rounded to the nearest whole number as instructed.

A nurse is preparing to administer gentamicin 36 mg IM to a school-age child. Available is gentamicin injection 40 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.)
Full Explanation
To find out how many mL of gentamicin the nurse should administer, we need to set up a proportion. If 40 mg of gentamicin is equivalent to 1 mL, then 36 mg of gentamicin is equivalent to x mL.
The proportion can be writen as 40/1 = 36/x. Solving for x, we get x = (36 * 1) / 40 = 0.9 mL.
The answer is rounded to the nearest tenth as instructed.
A nurse is preparing to administer digoxin 7.5 mcg/kg/day PO daily to a school-age child who weighs 52 lb. Available is digoxin elixir 50 mcg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Full 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 3.5 mL per dose. The answer is rounded to the nearest tenth as instructed.
A nurse is preparing to administer magnesium hydroxide 15 mL PO to a school-age child. How many tablespoons 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.)
Full 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.
