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.

Correct Answer is ["11.6"]
Explanation
To calculate this, first convert the child's weight from pounds to kilograms: 64 lb * (1 kg / 2.2 lb) = 29.09 kg. Then, calculate the dose of vancomycin in mg: 20 mg/kg * 29.09 kg = 581.8 mg.
Finally, divide the dose in mg by the concentration of the vancomycin injection to find the volume to administer: 581.8 mg / (50 mg/mL) = 11.636 mL/dose, which rounds to 11.6 mL when rounded to the nearest tenth.
Correct Answer is ["133"]
Explanation
To calculate this, divide the volume of the infusion by the infusion time to find the rate: 800 mL / 6 hr =
133.33 mL/hr, which rounds to 133 mL/hr when rounded to the nearest whole number.
