Answer :
To infuse 10 mEq KCL per hour using the provided 40 mEq in 100 mL solution, the infusion will run at 25 mL/hour, and the 100 mL bag will last 4 hours. Thus, if it starts at 10 AM, it will complete at 2 PM.
To determine the completion time for the intravenous KCL infusion, we need to calculate the total time required to deliver the prescribed dose. The pharmacy provided a solution labeled 40 mEq KCL in 100 mL D5W. The doctor has ordered 10 mEq per hour. To calculate the total volume needed for a one-hour dose: 10 mEq/hour * (100 mL / 40 mEq) = 25 mL/hour. Since the entire 100 mL bag contains 40 mEq, this bag will last 4 hours (because 40 mEq/10 mEq per hour = 4 hours).
If the infusion starts at 10 AM and runs for 4 hours, it will be completed at 2 PM on the same day. This calculation ensures accuracy in medication delivery, which is crucial in the treatment of conditions such as hypokalemia.
