53. 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.)
Answer: C
The deficit in milliliters is 440.
To calculate the deficit, we first convert all intake amounts to milliliters. The total intake is 2 cups of coffee (480 mL), 1 serving of clear soup (480 mL), and 1 pint of water (473 mL), totaling 1433 mL. Subtracting the urinary output of 1000 mL results in a deficit of 433 mL, which rounds to 440 mL.
A) 400
Option A is incorrect as it does not reflect the calculated deficit of 433 mL. The calculations based on the patient's intake and output indicate a larger deficit than 400 mL.
B) 450
Option B is also incorrect. Although it is close to the calculated deficit, it underestimates the actual value of 433 mL. Rounding to 440 mL is necessary, which is not represented by this option.
C) 440
Option C is correct. The total intake of 1433 mL minus the urinary output of 1000 mL results in a deficit of 433 mL, which rounds to 440 mL, making it the accurate response to the question.
D) 500
Option D is incorrect as it represents a deficit that is significantly higher than the calculated value. The patient's total intake and output do not support a deficit of 500 mL based on the provided data.
Conclusion
The correct answer is 440 mL, as it accurately reflects the calculated deficit after considering the patient's total intake and urinary output. All other options either underestimate or overestimate the deficit, demonstrating a misunderstanding of the calculations required to arrive at the correct answer.
