A) 25 mg/hour
B) 25 mL/hour
C) 63 mL/hour
D) 10 mL/hour
E) 250 mL/hour

To calculate the flow rate, we need to determine the amount of furosemide that needs to be administered per hour. Since the total dose is 100 mg and it needs to be administered over four hours, the hourly dose is 100 mg / 4 hours = 25 mg/hour.Now, we need to calculate the volume of solution that contains 25 mg of furosemide. Since the 500 mL bag contains 200 mg of furosemide, the volume of solution that contains 25 mg of furosemide is (25 mg / 200 mg) * 500 mL = 62.5 mL.Therefore, the flow rate should be 62.5 mL/hour, which is closest to option C) 63 mL/hour.
