Answer:
125 milliliters will be administered over 1 hour.
Explanation:
To calculate the amount of the solution to be administered over 1 hour, we need to divide the total amount by the time period.
So, if 500 mL of 2% sterile solution is to be administered over a period of 4 hours, then the amount to be administered per hour can be calculated as follows:
500 mL ÷ 4 hours = 125 mL/hour
