A client in DKA is ordered regular insulin at 7 units per hour for the current blood glucose level. The institution protocol is to add 100 units of regular insulin to a 150 ml bag of normal saline. What is the correct rate for the nurse to set the IV pump for this dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Step 1: Determine the concentration of insulin in the IV bag. 100 units of insulin are added to 150 mL of normal saline. 100 units ÷ 150 mL = (100 ÷ 150) = 0.6667 units per mL Result: 0.6667 units per mL Step 2: Calculate the rate in mL per hour needed to deliver 7 units per hour. 7 units per hour ÷ 0.6667 units per mL = (7 ÷ 0.6667) = 10.5 mL per hour Result: 10.5 mL per hour The correct rate for the nurse to set the IV pump is 10.5 mL per hour.
