A nurse is preparing to administer cefoxitin 400 mg by intermittent IV bolus over 1 hr to a school-age child. Available is cefoxitin 400 mg in 50 mL dextrose 5% in water. The nurse should ensure the IV pump is set 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 ["50"]
To calculate the IV pump setting, you would use the formula: Volume (mL) over Time (hr) = Rate (mL/hr). In this case, the total volume of the cefoxitin solution is 50 mL, and it needs to be administered over 1 hour. Therefore, the nurse should set the IV pump to deliver 50 mL/hr. When rounding to the nearest whole number, the rate remains 50 mL/hr.

Correct Answer is ["300"]
Explanation
To calculate the infusion rate in mL/hr, you can use the formula: (Total Volume in mL) / (Time in hours) = Rate in mL/hr. For lactated Ringer's 150 mL to be infused over 30 minutes, you would first convert the time to hours, which is 0.5 hours (since 30 minutes is half an hour). Then, divide the total volume by the time: 150 mL / 0.5 hours = 300 mL/hr.
Correct Answer is ["83"]
Explanation
To calculate the infusion rate for an IV, you would divide the total volume of IV fluid (1,000 mL) by the time in hours over which the infusion is to run (12 hr). This calculation gives you the rate in mL/hr. So, for 1,000 mL of sodium chloride to be infused over 12 hours, the calculation is 1,000 divided by 12, which equals approximately 83.33 mL/hr. When rounding to the nearest whole number, the IV pump should be set to deliver 83 mL/hr.
