After converting the recommended 8 glasses (of 8 ounces each) to milliliters and subtracting the urinary output of 1500 mL, the person has a net liquid gain of 393 mL.
To determine the net liquid gain or loss, one must calculate the difference between the intake and output of fluids. If an adult drinks 8 glasses of 8 ounces (which is 64 ounces in total), this translates to approximately 1893 mL of liquid intake (since 1 ounce is roughly 29.57 mL). Given the urinary output is 1500 mL, the net liquid gain would be the liquid intake minus the urinary output.
The following calculation shows the net gain:
- Liquid Intake: 8 glasses × 8 ounces/glass × 29.57 mL/ounce = 1893 mL
- Urinary Output: 1500 mL
- Net Liquid Gain: 1893 mL intake - 1500 mL output = 393 mL
So, the person has a net liquid gain of 393 mL for the day assuming they followed the recommended fluid intake and had a urinary output of 1500 mL.
