Fluid Balance Chart
1. Units in Part A Numeracy
A fluid balance chart is a 24-hour clinical document used to track a patient’s total fluid intake and output, crucial for preventing overload or dehydration. It records oral, intravenous, and food intake against urine, vomit, and drain losses.
The formula is:
Fluid Balance = Total Intake (mL) - Total Output (mL)
Check a filled fluid chart below, but in your CBT exam fluid input and out put section already filled, your task is to find out Balance from total fluids input and output.


Equation: Total Input - Total output
950 - 505 = 445, add '+' to make it positive balance
Answer= + 445 mL
