What is the infusion time for 800 mL of D5/LR being infused at a rate of 125 mL/hr?

To determine the infusion time for 800 mL of D5/LR (5% Dextrose in Lactated Ringer's solution) being infused at a rate of 125 mL/hr, you need to divide the total volume to be infused by the rate of infusion.

The formula used is:

Infusion Time (hours) = Total Volume (mL) / Infusion Rate (mL/hr)

Substituting the values:

Infusion Time = 800 mL / 125 mL/hr = 6.4 hours

When approximated to the nearest hour, this indicates a total infusion time of about 6 hours because the infusion cannot practically be administered in a fraction of an hour easily.

The provided correct answer reflects this calculation, indicating that it takes approximately 6 hours to infuse 800 mL at that rate. Understanding this calculation is crucial for nurses to accurately manage IV fluid administration and ensure patient safety.
