If a medication is administered at a rate of 200 mL/hour, how much will be given in 4 hours?

To determine the total volume of medication given in 4 hours at a rate of 200 mL/hour, you simply multiply the rate of administration by the duration of time.

You calculate this by taking the rate (200 mL/hour) and multiplying it by the number of hours (4 hours):

[ 200 , \text{mL/hour} \times 4 , \text{hours} = 800 , \text{mL} ]

Therefore, the total amount of medication administered in 4 hours is 800 mL. This method of multiplication accurately reflects how volume accumulates over time when given at a constant rate, reinforcing the principle that consistent administration rates lead to predictable total volumes over designated time intervals.
