To determine the hourly flow rate of the IV fluid, you need to divide the total volume of the fluid by the total time in hours. In this case, the total volume is 1.5 liters, which should first be converted to milliliters since the flow rate is sought in mL.

1.5 liters is equivalent to 1500 milliliters (as 1 liter equals 1000 milliliters).

Next, the total time for the infusion is 10 hours. To find the hourly flow rate, you divide the total volume (1500 mL) by the total time (10 hours):

1500 mL ÷ 10 hours = 150 mL/hour.

Thus, the hourly flow rate is 150 mL per hour, making this the correct answer. This calculation is essential for ensuring that the patient receives the correct volume of IV fluid over the specified time frame. Proper understanding of flow rates is a critical skill in IV therapy management to maintain effective treatment and patient safety.
