One side of a 6-sided die is numbered 4, 9, 12, 16, 20, and 24. What is the probability of rolling an even number?
- A. 5/6
- B. 3/4
- C. 2/3
- D. 1/3
Correct Answer: A
Rationale: To find the probability of rolling an even number, we identify the even numbers on the die, which are 4, 12, 16, 20, and 24 (5 even numbers). Since there are 6 total outcomes on a 6-sided die, the probability of rolling an even number is the number of favorable outcomes (5) divided by the total number of outcomes (6), resulting in a probability of 5/6.
What is the result of adding 23.5 and 7.025?
- A. 30.525
- B. 30.5
- C. 30.025
- D. 16.475
Correct Answer: A
Rationale: To find the sum of 23.5 and 7.025, you simply add the two numbers together: 23.5 + 7.025 = 30.525. Therefore, the correct answer is A, 30.525, which is the result of adding 23.5 and 7.025.
A patient is consuming a clear diet, and a healthcare professional is reviewing the daily intake and output (I&O). The urinary drainage bag records a total of 1,000 mL for the past 24 hours. The total intake is:
- A. 400
- B. 450
- C. 440
- D. 500
Correct Answer: C
Rationale: To calculate the total fluid intake, you must convert the various fluid types consumed into milliliters. The patient had 2 cups of coffee (2 x 8 oz = 16 oz), 1 clear soup (16 oz), and 1 pint of water (16 oz). Converting these values to milliliters: 16 oz coffee + 16 oz soup + 16 oz water = 48 oz = 1419.53 mL. Subtracting the total output of 1000 mL from the total intake of 1419.53 mL gives a fluid intake of 419.53 mL. Rounding to the nearest whole number, the total intake is 420 mL, corresponding to option C.
What is the result of dividing 18.104 by 0.002?
- A. 9052
- B. 0.09052
- C. 9.052
- D. 9.52
Correct Answer: A
Rationale: When dividing by a small decimal like 0.002, it's equivalent to multiplying by 500 (since 1 · 0.002 = 500). Thus, 18.104 — 500 = 9052. This process involves shifting the decimal point three places to the right to calculate the answer.
Which is the largest expression?
- A. 0.195833
- B. 1:20
- C. 1:22
- D. 1:02
Correct Answer: A
Rationale: Correct Answer: A: 0.195833
Rationale: To compare the expressions, convert them to decimal form. A: 0.195833, B: 1.20, C: 1.22, D: 1.02. A is the largest as it is closest to 1. B is 1.20, C is 1.22, and D is 1.02. A is larger than D by 0.175833, which is the greatest difference among the options, making A the largest expression.
