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 ["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 ["4.2"]

Explanation

Step 1: Convert the preschooler’s weight from pounds to kilograms. 37 lbs ÷ 2.2 = 16.8181 kg (rounded to four decimal places)

Step 2: Calculate the total daily dose of cephalexin in mg. 50 mg/kg/day × 16.8181 kg = 840.905 mg/day (rounded to three decimal places)

Step 3: Determine the number of doses per day. 24 hours ÷ 6 hours = 4 doses/day

Step 4: Calculate the dose per administration. 840.905 mg/day ÷ 4 doses/day = 210.22625 mg/dose (rounded to five decimal places)

Step 5: Convert the dose from mg to mL using the available suspension concentration. 250 mg ÷ 5 mL = 50 mg/mL

Step 6: Calculate the volume to be administered per dose. 210.22625 mg ÷ 50 mg/mL = 4.204525 mL (rounded to six decimal places)

Step 7: Round the final answer to the nearest tenth. 4.204525 mL rounded to the nearest tenth = 4.2 mL

Therefore, the nurse should administer 4.2 mL per dose.
