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.)

Answer and Explanation

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 ["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 ["125"]

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.
