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"]
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 ["850"]
Explanation
Magnesium hydroxide is measured in grams (g) and milligrams (mg). There are 1000 milligrams in 1 gram. Therefore, to convert 0.85 g to mg, we multiply 0.85 by 1000. This gives us 850 mg. The answer is rounded to the nearest whole number as instructed.
Correct Answer is ["0.65"]
Explanation
Let’s calculate this step by step:
Step 1: Convert the toddler’s weight from pounds (lb) to kilograms (kg) using the conversion factor 1 kg = 2.2 lbs.
24 lbs ÷ 2.2 lbs/kg = 10.91 kg
Step 2: Calculate the total amount of diazepam needed using the dosage of 0.3 mg/kg.
0.3 mg/kg × 10.91 kg = 3.27 mg
Step 3: Calculate the volume of diazepam injection to administer using the concentration of 5 mg/mL.
3.27 mg ÷ 5 mg/mL = 0.654 mL
Rounding to the nearest hundredth, the nurse should administer 0.65 mL of diazepam injection.
