1. What is the crystalline compound that is a product of protein metabolism known as?

• A. uracil
• B. urine
• C. ureter
• D. urea

Correct answer: D

Rationale: Urea is the correct answer. It is the crystalline compound formed in the liver from the breakdown of proteins, a byproduct of protein metabolism. Urea is excreted by the kidneys in the form of urine, aiding in the elimination of nitrogenous waste from the body. Uracil (Choice A) is a nitrogenous base found in RNA, not a product of protein metabolism. Urine (Choice B) is the liquid waste excreted by the kidneys but not the crystalline compound resulting from protein metabolism. Ureter (Choice C) is a duct that carries urine from the kidneys to the bladder, not the compound produced from protein metabolism.

2. What is another word for toxin?

• A. Impurity
• B. Element
• C. Remedy
• D. Poison

Correct answer: D

Rationale: The correct answer is D, Poison. A toxin is a harmful substance that can cause illness or death, and poison is a synonym commonly used to refer to such substances. Choices A, B, and C are incorrect because impurity refers to something being dirty or unclean, an element is a pure substance that cannot be broken down further, and a remedy is a solution or treatment for a problem, not a harmful substance like a toxin.

3. What is the best description for the word establish in the following sentence? Physicians use patch tests to establish the specific causes of contact dermatitis.

• A. Launch
• B. Introduce
• C. Endorse
• D. Determine

Correct answer: D

Rationale: In the given sentence, the word 'establish' is used in the context of identifying or finding out the specific causes of contact dermatitis through patch tests. The most fitting description for 'establish' in this context is 'Determine,' as it signifies the action of figuring out or ascertaining the specific causes. 'Launch,' 'introduce,' and 'endorse' do not capture the essence of what the physicians are doing in this scenario. They are not launching, introducing, or endorsing the causes; instead, they are trying to determine them through the patch tests.

4. Select the meaning of the word 'precipitous' in the sentence: 'The precipitous change was considered a good thing.'

• A. Difficult
• B. Abrupt
• C. Gentle
• D. Unanticipated

Correct answer: B

Rationale: The correct answer is 'B: Abrupt.' In this context, 'precipitous' is used to describe a change that occurs suddenly or abruptly. Choice A ('Difficult') is incorrect as it does not capture the sudden nature of the change. Choice C ('Gentle') is incorrect as it conveys the opposite meaning of 'precipitous.' Choice D ('Unanticipated') is incorrect as it focuses on the element of surprise rather than the suddenness of the change.

5. What is the best description for the word operated in this sentence? Rural communities are increasingly taking ownership of their hospitals, which may be operated by administrative medical groups.

• A. Performing surgery

Correct answer: C

Rationale: In the context of the sentence provided, the word 'operated' is best described as 'managed and run.' This choice accurately reflects the idea that rural communities are taking ownership and control of their hospitals, which may be overseen and operated by administrative medical groups. The word 'operated' here implies the day-to-day management and functioning of the hospitals, making option C the most suitable description in this context. Choices A, B, and D are incorrect as they do not capture the essence of 'operated' in the context of managing and running the hospitals.
