A client is to receive an IV of Sodium Chloride 0.9% injection (Normal Saline) 250 mL with KCl 10 mEq IV over 4 hours. What rate should the nurse program the client's IV infusion pump?

To determine the correct rate for the IV infusion, it is essential to calculate the infusion rate based on the total volume to be infused and the total time over which it will be administered.

The client is set to receive 250 mL of Normal Saline with KCl over a period of 4 hours. To find the appropriate rate in mL/hour, you divide the total volume (250 mL) by the total time (4 hours).

So the calculation is as follows:

250 mL ÷ 4 hours = 62.5 mL/hour.

When rounding to the nearest whole number, it is common to round up to 63 mL/hour. This aligns with the specifics of managing patient care, as infusion rates should often be set accurately for effective treatment. Thus, programming the IV infusion pump to deliver at 63 mL/hour is the correct approach, making this choice the appropriate answer.
