For a 1000 mL IV to infuse over 5 hours, what would be the flow rate in mL/hr?

To determine the flow rate in mL/hr for a 1000 mL IV fluid that needs to be infused over 5 hours, you start by dividing the total volume of the IV fluid by the time in hours.

In this case, you have 1000 mL to infuse over 5 hours. The calculation would be:

1000 mL ÷ 5 hours = 200 mL/hr

This means that in order to complete the infusion of the 1000 mL within the specified time frame of 5 hours, the flow rate should be set at 200 mL/hr.

Understanding the calculation helps in ensuring the accurate administration of IV fluids, preventing both under and over-infusion, which is crucial for patient safety. The other flow rates provided do not align with this calculation, confirming that 200 mL/hr is the only correct answer based on the required infusion over the specified time.
