If a provider orders one liter of NS to be infused over four hours, what rate would you set the IV pump?

To determine the correct infusion rate for one liter of normal saline (NS) to be infused over four hours, it is important to first convert the volume into milliliters since infusion rates are typically expressed in ml/hr. One liter is equivalent to 1000 milliliters.

Next, to find the required infusion rate, divide the total volume (1000 ml) by the total time (4 hours):

1000 ml ÷ 4 hours = 250 ml/hr.

Setting the IV pump to 250 ml/hr allows for the entire liter of NS to be infused within the specified four-hour timeframe, thus ensuring that the prescribed treatment is delivered accurately and safely. This is critical for maintaining fluid balance in patients and for the overall effectiveness of the treatment.
