Correct Answer is ["75"]

Explanation

Step 1 is to divide the total volume of TPN by the total time in hours.

So, 1800 mL ÷ 24 hr = 75 mL/hr.

Correct Answer is ["35"]

Explanation

Step 1 is: To find out how many mL/hr the nurse should set the infusion pump to deliver, we need to divide the total volume of enteral nutrition (840 mL) by the total time (24 hours).

So, the calculation is: 840 mL ÷ 24 hours = 35 mL/hr Therefore, the nurse should set the infusion pump to deliver 35 mL/hr.
