A nurse is preparing to administer 0.9% sodium chloride 100 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.)

Answer and Explanation

The Correct Answer is ["400"]

To find out how many mL/hr the IV pump should be set to deliver, we need to convert the infusion time

from minutes to hours.

Since there are 60 minutes in an hour, 15 minutes is equivalent to 15/60 = 0.25 hours.

If 100 mL of 0.9% sodium chloride is to be infused over 0.25 hours, then the rate of infusion is 100/0.25 = 400 mL/hr. The answer is rounded to the nearest whole number as instructed.

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 ["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.
