A nurse is preparing to administer dextrose 5% in 0.9% sodium chloride 125 mL IV to infuse over 15 min. The nurse should set the IV pump to deliver how many mL/hr? (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 ["500"]
To calculate this, first convert the infusion time from minutes to hours: 15 min * (1 hr / 60 min) = 0.25 hr.
Then, divide the volume of the infusion by the infusion time to find the rate: 125 mL / 0.25 hr = 500 mL/hr.

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.
Correct Answer is ["11.6"]
Explanation
To calculate this, first convert the child's weight from pounds to kilograms: 64 lb * (1 kg / 2.2 lb) = 29.09 kg. Then, calculate the dose of vancomycin in mg: 20 mg/kg * 29.09 kg = 581.8 mg.
Finally, divide the dose in mg by the concentration of the vancomycin injection to find the volume to administer: 581.8 mg / (50 mg/mL) = 11.636 mL/dose, which rounds to 11.6 mL when rounded to the nearest tenth.
