What is your default administration rate for IV fluids ordered as "bolus"? Is the infusion rate part of the order inputted by the ordering provider, or driven by nursing or pharmacy protocol?

In our system, the order is placed with an infusion rate of "bolus." For example, "0.9% sodium chloride, 1000 mL, IV, bolus" and the pharmacy staff assign a specific rate during order verification, like 1000 mL/hr, 500 mL/hr. I am wondering if anyone is doing this differently and would appreciate anything you could share regarding this practice.
