A nurse is preparing to administer 0.45% sodium chloride 1,000 mL IV to infuse over 8 hr. 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 ["125"]
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.

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 ["1.2"]
Explanation
Step 1 is to convert the child’s weight from pounds to kilograms since the dosage of morphine is prescribed in mg/kg. We know that 1 kg is approximately equal to 2.2 lb. So, the child’s weight in kg is:
51 lb ÷ 2.2 = 23.18 kg
Step 2 is to calculate the total amount of morphine the child should receive per dose. The doctor ordered 0.1 mg of morphine per kg of body weight. So, the total amount of morphine per dose is:
0.1 mg/kg × 23.18 kg = 2.318 mg
Step 3 is to calculate the volume of morphine injection to be administered. We know that the available morphine injection has a concentration of 2 mg/mL. So, the volume in mL is:
2.318 mg ÷ (2 mg/mL) = 1.159 mL
Rounding this to the nearest tenth gives 1.2 mL. So, the nurse should administer 1.2 mL of morphine injection per dose.
So, the correct answer is 1.2 mL.
