1. The triple point of a substance is the specific temperature and pressure at which all three phases (solid, liquid, and gas) can coexist in thermodynamic equilibrium. Which of the following statements about the triple point is true?

• A. It can vary depending on the container size.
• B. It is a unique point for each pure substance.
• C. The pressure at the triple point can be zero for some substances.
• D. The temperature at the triple point can be above the boiling point of the liquid phase.

Correct answer: B

Rationale: The triple point is a unique temperature and pressure where all three phases (solid, liquid, and gas) of a pure substance can coexist in equilibrium. It is a constant for each substance and independent of container size. Choice A is incorrect because the triple point is a fixed point regardless of the container size. Choice C is incorrect as the pressure at the triple point is specific for each substance and will not be zero unless the substance has unique properties. Choice D is incorrect since the temperature at the triple point is precisely defined and cannot be above the boiling point of the liquid phase.

2. To STANCH a wound is to ____ it.

• A. Expand
• B. Restrict
• C. Release
• D. Avoid

Correct answer: B

Rationale: The correct answer is B: 'Restrict.' To stanch a wound means to stop or restrict the flow of blood. Choice A, 'Expand,' is incorrect as it means to make something larger. Choice C, 'Release,' is incorrect as it means to set something free. Choice D, 'Avoid,' is incorrect as it means to keep away or prevent something.

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. What is Hydration?

• A. The process of dehydrating
• B. Maintenance of body fluid
• C. Loss of water
• D. Draining fluids

Correct answer: B

Rationale: Hydration refers to the maintenance of body fluids. Choice A is incorrect as it describes the opposite process, dehydration. Choice C is incorrect as it focuses on the result of inadequate hydration rather than the concept itself. Choice D is incorrect as it does not accurately define hydration but rather implies removing fluids.

5. What is a solution to insomnia?

• A. Developing good sleep habits and using herbs and spices.
• B. Avoiding physical activity.
• C. Staying awake for longer periods.
• D. Eating large meals before bed.

Correct answer: A

Rationale: The correct answer is A: Developing good sleep habits and using herbs and spices. The passage highlights that sleep hygiene, which involves developing good sleep habits and non-pharmacological therapies like herbs and spices, are solutions to insomnia. These methods aim to promote better sleep quality. Choices B, C, and D are incorrect. Avoiding physical activity, staying awake for longer periods, and eating large meals before bed can actually worsen insomnia symptoms and disrupt sleep patterns.
