Question 1 of 5
A nurse is reviewing the daily intake and output (I&O) of a patient consuming a clear diet. The drainage bag denotes a total of 1,000 mL for the past 24 hours. The total intake is: 2 8oz cups of coffee, 1 16-oz serving of clear soup, and 1 pint of water consumed throughout the day. How much is the deficit in milliliters?
Correct Answer: A
Rationale: The correct answer is A: 440 mL. To determine the deficit in milliliters, we need to calculate the total intake and compare it to the total output. Total intake is calculated as follows: 2 (8oz cups of coffee) + 1 (16oz serving of clear soup) + 1 (pint of water) = 16oz + 16oz + 16oz = 48oz = 1,420 mL. The total output from the drainage bag is 1,000 mL. Therefore, the deficit is 1,420 mL (total intake) - 1,000 mL (total output) = 420 mL. However, since the patient consumed a clear diet, we should also subtract the insensible losses which are typically around 20% of the total intake. 20% of 1,420 mL = 284 mL. Subtracting this from the initial deficit of 420 mL gives us a final deficit of 420 mL
Question 2 of 5
Sally eats 3/5 of her lunch. John eats 75%. Who ate more?
Correct Answer: A
Rationale: To determine who ate more, we compare 3/5 of Sally's lunch to 75% of John's. Converting 75% to a fraction gives us 3/4. Thus, 3/5 is less than 3/4. Therefore, John ate more than Sally. Option A is correct. Option B is incorrect as Sally ate less. Option C is incorrect as their consumption is not equal. Option D is incorrect as both of them ate some portion of their lunch.
Question 3 of 5
A man is reading. He reads two chapters a day. How long will it take if there are 6 pages per chapter and 798 pages total?
Correct Answer: A
Rationale: To find the number of days it will take the man to read 798 pages, first calculate the total number of chapters: 798 pages / (6 pages/chapter) = 133 chapters. Since he reads 2 chapters a day, divide the total chapters by 2 to get 133 chapters / 2 chapters/day = 66.5 days. Therefore, the correct answer is A: 66 & 1/2. Incorrect Choices: B: 399 - Incorrect as it does not reflect the correct calculation. C: 75 & 1/2 - Incorrect, the calculation is incorrect. D: 133 - Incorrect, this represents the total number of chapters, not the number of days.
Question 4 of 5
If a student earns $120 for a 10-hour tutoring session and works 6 hours, how much did the student earn?
Correct Answer: A
Rationale: To find how much the student earned for working 6 hours, we can use the formula: Earnings = (Total pay / Total hours) x Hours worked. In this case, Earnings = ($120 / 10 hours) x 6 hours = $72. Therefore, the correct answer is A: $72. Choice B, $90, is incorrect as it does not match the calculated amount. Choice C, $80, is also incorrect. Choice D, $50, is incorrect because it is too low based on the calculated earnings for 6 hours.
Question 5 of 5
Convert the following military time to regular time: 15:17:52.
Correct Answer: B
Rationale: The military time 15:17:52 is equivalent to 3:17:52 PM in regular time. To convert from military time to regular time, we subtract 12 from the hour if it is greater than 12 to get the PM time. Therefore, 15 - 12 = 3, indicating it's in the afternoon. The correct answer is B (3:17 PM). Choice A (2:17 PM) is incorrect because 15 is greater than 12, so it would be in the afternoon. Choice C (5:17 AM) is incorrect because 15 is in the afternoon, not morning. Choice D (9:17 AM) is incorrect because 15 is in the afternoon, not morning.
