A nurse is preparing to administer dextrose 5% in water 800 mL IV to infuse over 6 hr to an adolescent client. 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 ["133"]
To calculate this, divide the volume of the infusion by the infusion time to find the rate: 800 mL / 6 hr =
133.33 mL/hr, which rounds to 133 mL/hr when rounded to the nearest whole number.

Correct Answer is ["0.48"]
Explanation
To calculate this, first convert the child's weight from pounds to kilograms: 70 lb * (1 kg / 2.2 lb) = 31.82 kg. Then, calculate the total daily dose of ephedrine in mg: 3 mg/kg/day * 31.82 kg/day = 95.45 mg/day.
Since the daily dose is divided into equal doses every 6 hours, calculate the dose per administration: 95.45 mg/day / (24 hr/day / 6 hr/dose) = 23.86 mg/dose.
Finally, divide the dose in mg by the concentration of the ephedrine injection to find the volume to administer: 23.86 mg / (50 mg/mL) = 0.477 mL, which rounds to 0.48mL when rounded to the nearest hundredth.
Correct Answer is ["500"]
Explanation
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.
