Pamidronate 90mg is diluted in 500mL of compatible infusion fluid. This infusion has to be given over 1.5 hours. What rate should you set the infusion pump at, in ml/hr, to deliver this dose?

To calculate the rate at which the infusion pump should be set, you can use the following formula:

\[
\text{Infusion Rate} = \frac{\text{Total Volume}}{\text{Total Time}}
\]

Where:
- **Total Volume** = 500 mL (the volume of the infusion fluid)
- **Total Time** = 1.5 hours

Convert 1.5 hours into minutes for the infusion rate in mL/hour:
\[
1.5 \text{ hours} = 1.5 \times 60 = 90 \text{ minutes}
\]

However, to directly calculate the infusion rate in mL/hour:

\[
\text{Infusion Rate} = \frac{500 \text{ mL}}{1.5 \text{ hours}} = \frac{500}{1.5} = 333.\overline{3} \text{ mL/hr}
\]

So, the infusion pump should be set at **333.3 mL/hr**.
