To calculate the IV pump rate (mL/hr), we can use the following formula:

$\text{Pump rate (mL/hr)} = \frac{\text{Total volume (mL)}}{\text{Time (hours)}}$

Given:

• Total volume = 250 mL
• Time = 2.5 hours

Substitute these values into the formula:

$\text{Pump rate (mL/hr)} = \frac{250 \, \text{mL}}{2.5 \, \text{hours}} = 100 \, \text{mL/hr}$

So, the nurse should set the IV pump to 100 mL/hr.

Tip: Always double-check infusion rates for medications with narrow therapeutic ranges like vancomycin to prevent toxicity.
