The nurse infuses a dose of medication in 45 minutes. If the nurse determines the medication should be infused at a rate that is 20% slower, the nurse should infuse the medication over what period of time?
49 minutes
54 minutes
56 minutes
60 minutes
The Correct Answer is B
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=9 minutes
Add the extra time to the original time:
The new infusion time is: 45 minutes + 9 minutes =54 minutes
Therefore, the nurse should infuse the medication over: 54 minutes
