Explanation
To determine the new infusion time when the rate is 20% slower, follow these steps:
Find the original infusion time:
The original time is 45 minutes.
Calculate the 20% slower rate:
A 20% slower rate means the time will be increased by 20%.
20% of 45 minutes is: 0.20×45=9minutes
Add the extra time to the original time:
The new infusion time is: 45minutes + 9minutes =54minutes
Therefore, the nurse should infuse the medication over: 54 minutes
