A nurse is preparing to administer 0.9% sodium chloride 100 mL IV to infuse over 15 min. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation
The Correct Answer is [“400 mL\/hr”]
To calculate the infusion rate in mL/hr, you can use the following formula:Flow rate (mL/hr)=(Volume to be infused (mL)Time (hours))\text{Flow rate (mL/hr)} = \left(\frac{\text{Volume to be infused (mL)}}{\text{Time (hours)}}\right)Flow rate (mL/hr)=(Time (hours)Volume to be infused (mL))
- Volume to be infused: 100 mL
- Time: 15 minutes = 15/60 hours = 0.25 hours
Now, plug in the values:Flow rate (mL/hr)=(100 mL0.25 hours)=400 mL/hr\text{Flow rate (mL/hr)} = \left(\frac{100 \text{ mL}}{0.25 \text{ hours}}\right) = 400 \text{ mL/hr}Flow rate (mL/hr)=(0.25 hours100 mL)=400 mL/hr
Answer: 400 mL/hr
Explanation: The nurse should set the IV pump to deliver 400 mL/hr to infuse 100 mL of 0.9% sodium chloride over 15 minutes.
