Correct Answer is ["400"]

Explanation

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 ["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.
