1. What is 0.75 as a fraction?

• A. 3/4
• B. 7/10
• C. 15/20
• D. 1/2

Correct answer: A

Rationale: To convert a decimal to a fraction, you can write the decimal as a fraction with the decimal part as the numerator and a power of 10 as the denominator. In this case, 0.75 can be written as 75/100. Simplifying this fraction by dividing both the numerator and denominator by 25 gives you 3/4. Therefore, the correct answer is A. Choice B (7/10), Choice C (15/20), and Choice D (1/2) are incorrect because they do not represent the correct conversion of 0.75 into a fraction.

2. Which of the following is an example of a nosocomial infection?

• A. The common cold contracted from a family member
• B. A urinary tract infection (UTI) acquired during a catheterization
• C. A fungal skin infection from contaminated soil
• D. Food poisoning from undercooked chicken

Correct answer: B

Rationale: A nosocomial infection, also known as a healthcare-associated infection (HAI), is an infection that is acquired in a healthcare setting. In this case, a UTI acquired during a catheterization procedure is a classic example of a nosocomial infection. Catheterization involves the insertion of a tube into the urinary tract, which can introduce bacteria into the urinary system and lead to an infection. Nosocomial infections are a significant concern in healthcare settings due to the potential for increased morbidity, mortality, and healthcare costs. Let's review the other options: A) The common cold contracted from a family member - This is not a nosocomial infection as it is acquired outside of a healthcare setting. C) A fungal skin infection from contaminated soil - This is not a nosocomial infection as it is acquired from environmental exposure, not in a healthcare setting.

3. Which term describes a substance's ability to undergo a change that transforms it into a different substance?

• A. Density
• B. Mass
• C. Reactivity
• D. Volume

Correct answer: C

Rationale: Reactivity refers to a substance's ability to undergo a change that transforms it into a different substance through a chemical reaction. In this context, reactivity specifically refers to the chemical behavior of a substance. Density, mass, and volume are physical properties of a substance and do not describe its ability to undergo a chemical change. Density is the mass per unit volume, mass is the amount of matter in an object, and volume is the amount of space occupied by an object. Therefore, reactivity is the most appropriate term to describe a substance's ability to undergo a transformation into a different substance.

4. Simplify the expression 3x - 5x + 2.

• A. -2x + 2
• B. -8x
• C. 2x + 2
• D. -2x

Correct answer: D

Rationale: When simplifying the expression 3x - 5x + 2, start by combining like terms. -5x is subtracted from 3x to give -2x. Adding 2 at the end gives the simplified expression -2x. Therefore, the correct answer is -2x. Choice A, -2x + 2, incorrectly adds 2 at the end. Choice B, -8x, incorrectly combines the coefficients of x without considering the constant term. Choice C, 2x + 2, incorrectly adds the coefficients of x without simplifying.

5. A 'competitive salary' is one that is

• A. Much less than salaries offered for comparable jobs
• B. Much greater than salaries offered for comparable jobs
• C. Similar to the average salary offered for comparable jobs
• D. Impossible to compare to the salaries offered for comparable jobs

Correct answer: C

Rationale: A competitive salary is one that is similar to the average salary offered for comparable jobs. In the context of the job advertisement provided, a competitive salary is typically in line with what other employers are paying for similar positions to attract and retain the best talent in the industry. Choice A is incorrect because a competitive salary is not 'much less' than salaries offered for comparable jobs; it aims to be competitive. Choice B is incorrect as a competitive salary is not 'much greater' than salaries offered for comparable jobs; it aims to be fair and competitive. Choice D is incorrect as a competitive salary is not 'impossible to compare to' the salaries offered for comparable jobs; it is meant to be competitive and aligned with industry standards.
