Mr. Thomas is on restricted fluids. He drank 180 ml of coffee, 90 ml of juice, and another cup of 120 ml. What is his total fluid intake for the day?
Mr. Thomas's total fluid intake for the day is 390 ml.
To find Mr. Thomas's total fluid intake, we simply add the volumes of all the liquids he consumed: 180 ml of coffee, 90 ml of juice, and 120 ml from another cup, resulting in a total of 390 ml.
This choice is incorrect because it underestimates the total intake. If we sum the individual amounts consumed (180 ml + 90 ml + 120 ml), the result exceeds 346 ml, indicating that this option miscalculates the total fluid intake.
This is the correct answer because adding the amounts consumed (180 ml + 90 ml + 120 ml) gives precisely 390 ml. This calculation accurately reflects Mr. Thomas's total fluid intake for the day.
This option is incorrect as it significantly overestimates Mr. Thomas's fluid intake. The total of 180 ml + 90 ml + 120 ml is far less than 810 ml, indicating a miscalculation in the addition of his fluid consumption.
This choice is also incorrect because it suggests an even higher total fluid intake than option C. The sum of the fluids consumed does not come close to 854 ml, demonstrating a clear error in calculating Mr. Thomas's total fluid intake.
Mr. Thomas's total fluid intake of 390 ml is derived from summing the individual beverages he consumed throughout the day. The other options either underestimate or overestimate this total, illustrating the importance of accurate addition in determining fluid intake, especially for patients on restricted diets.
