Question
A nurse is preparing to administer piperacillin 3.375 g by intermittent IV bolus every 6 hr.Available in piperacillin 3.375 g in dextrose 5% in water (DsW) 100 mL to infuse over 30 min.The nurse should set the IV pump to deliver how many mL/hr?A. 33 mL/hr.B. 100 mL/hr.C. 200 mL/hr.D. 400 mL/hr.
Solution
The nurse is supposed to infuse 100 mL over 30 minutes. To convert this to mL/hr, we need to know that there are 60 minutes in an hour.
Here's the step-by-step calculation:
- We know that the nurse is infusing 100 mL over 30 minutes.
- To find out how much is infused in one minute, we divide 100 mL by 30 minutes. This gives us approximately 3.33 mL/minute.
- To convert this to an hourly rate, we multiply by 60 (since there are 60 minutes in an hour).
So, 3.33 mL/minute * 60 minutes/hour = 200 mL/hour.
Therefore, the nurse should set the IV pump to deliver 200 mL/hr. So, the answer is C. 200 mL/hr.
