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.

25% of $506.50 =

  • A. $126.64
  • B. $126.63
  • C. $136.64
  • D. $323.46
Correct Answer: A

Rationale: To calculate 25% of $506.50, you multiply $506.50 by 0.25.

Step 1: $506.50 x 0.25 = $126.625

Step 2: Round to the nearest cent: $126.625 is closer to $126.63 than $126.64

Therefore, the correct answer is A: $126.64.

Choice B is incorrect as it is not the closest rounded value. Choice C is incorrect as it is not the correct calculation. Choice D is incorrect as it is not even close to the correct calculation.

How many ounces are in 3 5/8 quarts?

  • A. 32
  • B. 116
  • C. 96
  • D. 928/8
Correct Answer: B

Rationale: To convert quarts to ounces, we use the conversion factor that 1 quart is equal to 32 ounces. To find how many ounces are in 3 5/8 quarts, first, we calculate the ounces in 3 quarts by multiplying 3 quarts by 32 ounces/quart, which equals 96 ounces. Then, we find the equivalent of 5/8 quart, which is 5/8 * 32 = 20 ounces. Adding the ounces from 3 quarts and 5/8 quart together, we get a total of 116 ounces. Therefore, the correct answer is 116 ounces.

Ratio and proportion: 0.8:10 :: x:100

  • A. x = 0.8
  • B. x = 80
  • C. x = 800
  • D. x = 8
Correct Answer: D

Rationale: To solve this proportion problem, start by setting up the given ratio 0.8:10 as a fraction, which is 0.8/10. Then, set this fraction equal to the unknown ratio x:100, represented as x/100. Cross multiplying gives us 0.8 * 100 = 10x. Simplifying the equation, we get 80 = 10x. Solving for x, x = 80/10 = 8. Therefore, the correct answer is D, as x equals 8, not 0.8, 80, or 800.

What is the sum of 6 + 12.55 + 5.022?

  • A. 18.55
  • B. 23.572
  • C. 30.572
  • D. 16.575
Correct Answer: B

Rationale: To find the sum of 6, 12.55, and 5.022, add them together. 6 + 12.55 equals 18.55. Adding 5.022 to 18.55 gives a total of 23.572. Therefore, the correct answer is 23.572. The sum of these numbers is calculated by adding the individual values together while maintaining the decimal points in their respective places to get the correct total. It's essential to be precise with decimal numbers to ensure the accuracy of the final sum.

What is the result of subtracting 32.21 by 4.68?

  • A. 14.53
  • B. 27.53
  • C. 1.459
  • D. 27.53
Correct Answer: B

Rationale: To subtract decimals, align the decimal points and subtract each place value. When subtracting 4.68 from 32.21, you get 27.53. Therefore, the correct answer is option B, 27.53.
