Nursing Elites

1. Within a nursing program, 25% of the class wanted to work with infants, 60% wanted to work with the elderly, 10% wanted to assist general practitioners, and the rest were undecided. What fraction of the class wanted to work with the elderly?

• A. 1/4
• B. 1/10
• C. 3/5
• D. 1/20

Correct answer: C

Rationale: To find the fraction of the class wanting to work with the elderly, we convert the percentage to a fraction. 60% can be written as 60/100, which simplifies to 3/5. Therefore, 3/5 of the class wanted to work with the elderly. Choice A (1/4), choice B (1/10), and choice D (1/20) do not represent the fraction of the class wanting to work with the elderly, making them incorrect.

2. What is the median of the data set: 3, 5, 7, 9, 11?

• A. 3
• B. 7
• C. 9
• D. 5

Correct answer: B

Rationale: To find the median of a set of numbers, you arrange them in ascending order and then find the middle value. Given the data set 3, 5, 7, 9, 11, when arranged in ascending order, becomes 3, 5, 7, 9, 11. The middle value in this set is 7, making it the median. Choice A (3) is the smallest value, not the middle value. Choice C (9) and Choice D (5) are not the middle values of the set either. Therefore, the correct answer is B (7).

3. Which unit of measurement is larger, inches or centimeters?

• A. Inches are larger
• B. Centimeters are larger
• C. They are the same size
• D. It depends on the measurement

Correct answer: A

Rationale: Inches are larger than centimeters. This is because one inch is equivalent to 2.54 centimeters. Therefore, when comparing the two units, inches are greater in length than centimeters. Choice B is incorrect as centimeters are smaller than inches. Choice C is incorrect as inches and centimeters are not the same size. Choice D is incorrect as the relationship between inches and centimeters is fixed, with inches being larger in general.

4. Solve this equation: 2x+8=0

• A. -4
• B. 3
• C. 5
• D. 0

Correct answer: A

Rationale: To solve 2 𝑥 + 8 = 0 2x+8=0: Subtract 8 from both sides: 2 𝑥 = − 8 2x=−8 Divide both sides by 2: 𝑥 = − 8 2 = − 4 x= 2 −8 ​ =−4 Therefore, the solution is 𝑥 = − 4 x=−4.

5. Jacob has $100. She spends 87% of the money. She then invests the remaining amount and earns a profit of 75%. How much money does she now have?

• A. $13.00
• B. $87.00
• C. $22.75
• D. $9.75

Correct answer: C

Rationale: Jacob spends 87% of $100, which is $87, leaving her with $13. When she invests the remaining $13 and earns a 75% profit, she gains an additional $9.75. Thus, the total amount she now has is $13 (remaining amount) + $9.75 (profit) = $22.75. Choice A is incorrect as it reflects the remaining amount before investing and earning a profit. Choice B is incorrect as it does not account for the profit earned from the investment. Choice D is incorrect as it only considers the profit amount, not the total sum.
