1. Round to the nearest whole number. Change the fraction to a percent: 17/80 =

• A. 20%
• B. 21%
• C. 22%
• D. 23%

Correct answer: B

Rationale: To convert 17/80 to a percent, we divide 17 by 80 to get 0.2125. Multiplying by 100, we get 21.25%. Rounding to the nearest whole number, 21.25% becomes 21%. Choice A (20%) is incorrect because rounding 21.25% down to the nearest whole number gives 21%. Choice C (22%) is incorrect as it is the next whole number after 21. Choice D (23%) is incorrect as it is more than 21.25% and thus rounds up to 22%.

2. Which of the following words or phrases fits best in the following sentence? If you ever ___________ at County Medical, you would know how grueling a shift there can be.

• A. work
• B. are working
• C. had worked
• D. working

Correct answer: A

Rationale: The word 'work' (option A) is the most suitable choice for the sentence. The sentence is in the simple present tense and is discussing a general scenario or experience. The present simple tense is used to describe habits, routines, or general truths. Therefore, the word 'work' best fits in this context to indicate a general experience at County Medical without specifying a particular timeframe. Choices B, C, and D create incorrect tenses or imply specific past actions, which do not align with the intended meaning of the sentence.

3. In nature, water vapor becomes liquid water through the process of ___________.

• A. condensation
• B. sublimation
• C. precipitation
• D. absorption

Correct answer: A

Rationale: In nature, water vapor becomes liquid water through the process of condensation. Condensation occurs when water vapor cools and changes its state from a gas to a liquid, forming droplets that we commonly see as water droplets on surfaces or clouds in the sky. Sublimation refers to the transition from a solid to a gas without passing through the liquid phase. Precipitation is the process where water in the atmosphere falls to the ground as rain, snow, sleet, or hail. Absorption is the process of one substance being taken in by another.

4. A chemist takes 100 mL of a 40 g NaCl solution and dilutes it to 1L. What is the concentration (molarity) of the new solution?

• A. 0.04 M NaCl
• B. 0.25 M NaCl
• C. 0.40 M NaCl
• D. 2.5 M NaCl

Correct answer: C

Rationale: Initially, the chemist has 40 g of NaCl in 100 mL of solution. To find the initial molarity, we need to calculate the number of moles of NaCl using the molar mass of NaCl (58.44 g/mol). After dilution to 1 L, the molarity of the new solution can be calculated by dividing the moles of NaCl by the total volume in liters. Therefore, the concentration (molarity) of the new solution is 0.40 M NaCl. Choice A (0.04 M NaCl) is incorrect because it doesn't consider the correct molar concentration after dilution. Choice B (0.25 M NaCl) is incorrect as it also doesn't account for the correct molar concentration post-dilution. Choice D (2.5 M NaCl) is incorrect as it is too concentrated given the initial amount of NaCl and the dilution factor.

5. What does the term 'Sallow' mean in reference to skin?

• A. Has a reddish tint
• B. Has a yellowish tint
• C. Has a bluish tint
• D. Has a greenish tint

Correct answer: B

Rationale: Sallow skin refers to skin that has a yellowish tint. The term 'sallow' specifically describes a complexion that appears somewhat yellowish or unhealthy. Choice A, 'Has a reddish tint,' is incorrect as sallow skin is not reddish. Choice C, 'Has a bluish tint,' is incorrect as sallow skin is not bluish. Choice D, 'Has a greenish tint,' is incorrect as sallow skin is not greenish.
