If a school-aged child with acute glomerulonephritis is allowed a fluid intake based on previous output plus 40 mL, how much fluid should the child receive from 3:00 PM to 11:00 PM if their total daily allowance is 180 mL?

To determine how much fluid the child should receive from 3:00 PM to 11:00 PM, we need to consider the context of the given fluid allowance. The total daily fluid allowance is 180 mL. This total includes the child's previous output plus an additional 40 mL as indicated in the question.

The time period from 3:00 PM to 11:00 PM is 8 hours. If we assume that the 180 mL is meant to cover the entire 24 hours of the day, we can calculate the corresponding hourly fluid allowance.

By dividing the total daily allowance of 180 mL by 24 hours, we determine the hourly allowance:

[

180 , \text{mL} \div 24 , \text{hours} = 7.5 , \text{mL/hour}

]

Next, we need to calculate the total fluid allowance for the 8-hour period from 3:00 PM to 11:00 PM:

[

7.5 , \text{mL/hour} \times 8 , \text{hours} = 60 , \text{mL}

]

This calculation indicates that the child
