A patient is consuming a clear diet, and their urinary drainage bag indicates a total output of 1,000 mL in the past 24 hours. The patient's total intake includes 2 8-oz cups of coffee, 1 16-oz serving of clear soup, and 1 pint of water. What is the deficit in milliliters? (Enter a numeric value only. If rounding is necessary, round to the nearest whole number.)
- A. 400
- B. 450
- C. 440
- D. 500
Correct Answer: C
Rationale: To find the total intake, convert each volume to mL: 2 cups of coffee (8 oz each) = 2 x 8 x 29.5735 = 473.176 mL, 1 serving of clear soup (16 oz) = 16 x 29.5735 = 473.176 mL, and 1 pint of water = 473.176 mL. Thus, the total intake is 473.176 + 473.176 + 473.176 = 1,419.528 mL. The deficit is the difference between the total intake and output, which is 1,419.528 - 1,000 = 419.528 mL. When rounded to the nearest whole number, the deficit is 420 mL, making option C, 440, the closest choice.
