To adjust a flow rate, you will need to recalculate the infusion using

A. the remaining volume and original time: Using the original time does not reflect how much time is actually left for the infusion. This could lead to under- or over-infusion if the clock has already started. B. the original volume and time: This method is used only at the start of the infusion. Once some fluid has already infused, this combination is no longer valid for adjusting the current flow rate. C. the remaining volume and time: To accurately adjust the flow rate mid-infusion, the nurse must use the amount of fluid left to infuse and the remaining time ordered for the infusion. This ensures the patient receives the correct volume within the prescribed timeframe. D. the original volume and remaining time: Using the full original volume over the shortened remaining time would lead to an excessively high flow rate, potentially causing fluid overload or complications.
