A client is receiving an intravenous infusion of 1.5 L of saline solution at a rate of 75 mL/hr.
How many hours will it take to finish the infusion at the current rate?

The flow rate of infusion is 125 mL/hr.

This answer is correct because it is based on a simple division and rounding calculation. The nurse should follow these steps to determine the flow rate of infusion:

1) Subtract the start time of the infusion from the end time of the infusion to get the duration of the infusion in hours and minutes, as follows:

15:45 - 06:57 = 8:48

Therefore, the infusion lasted for 8 hours and 48 minutes.

2) Convert the duration of the infusion to hours only by dividing the minutes by 60, since there are 60 minutes in 1 hour. Add this to the hours, as follows:

8 + (48 / 60) = 8.8

Therefore, the infusion lasted for 8.8 hours.

3) Divide the volume of the infusion by the duration of the infusion to get the flow rate in milliliters per hour, as follows:

1000 mL / 8.8 hr = 113.64 mL/hr

Therefore, the flow rate is 113.64 mL/hr.

4) Round the flow rate to the nearest whole number, as follows:

113.64 mL/hr ≈ 114 mL/hr

Therefore, the flow rate is approximately 114 mL/hr.

5) Adjust the flow rate to a standard value that can be set on an IV pump or gravity drip chamber, as follows:

114 mL/hr → 125 mL/hr

Therefore, the flow rate of infusion is 125 mL/hr.

This number should be multiplied by inches in order to convert a patient's height measurement from inches to centimeters, because one inch is equal to 2.54 centimeters. To convert inches to centimeters, the formula is:

centimeters = inches × 2.54

For example, if a patient's height is 60 inches, then the height in centimeters is:

centimeters = 60 × 2.54
centimeters = 152.4

Therefore, the patient's height is 152.4 centimeters.
