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.)
The Correct Answer is ["400 mL\/hr"]
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 ["3.8"]
Explanation
To calculate the correct dose of acetaminophen for the toddler, follow these steps:
-
Convert pounds to kilograms:
- 26.4 lb * (1 kg / 2.2 lb) = 12 kg
-
Calculate the dose in mg:
- 12 kg * 10 mg/kg = 120 mg
-
Determine the volume to administer:
- 120 mg / 160 mg/5 mL = 3.75 mL
Therefore, the nurse should administer 3.8 mL of acetaminophen per dose.
answer = 3.8
Correct Answer is ["0.24"]
Explanation
To calculate this, first convert the infant's weight from pounds to kilograms: 21 lb * (1 kg / 2.2 lb) = 9.55 kg.
Then, calculate the total daily dose of clindamycin phosphate in mg: 15 mg/kg/day * 9.55 kg/day = 143.25 mg/day.
Since the daily dose is divided into equal doses every 6 hours, calculate the dose per administration: 143.25 mg/day / (24 hr/day / 6 hr/dose) = 35.81 mg/dose.
Finally, divide the dose in mg by the concentration of the clindamycin phosphate injection to find the volume to administer: 35.81 mg / (150 mg/mL) = 0.2387 mL/dose, which rounds to 0.24 mL when rounded to the nearest hundredth.
