Nursing Elites

1. The information presented is:

• A. Slanted in favor of newscasters
• B. Slanted against people with deep voices
• C. Balanced in its approach
• D. Not applicable

Correct answer: C

Rationale: The information is balanced in its approach. While the extract mentions that women tend to have shriller voices, making them less desirable public speakers, newscasters, or political candidates, it does not show bias in favor of newscasters or against people with deep voices. The main focus is on the impact of voice qualities such as harshness, rather than promoting or criticizing any specific group.

2. Select the meaning of the word 'parameters' in the sentence: 'The parameters of medical ethics require the nurse to report suspected child abuse.'

• A. Laws
• B. Limits
• C. Common sense
• D. Structure

Correct answer: B

Rationale: In the context of the sentence provided, 'parameters' refer to the limits or boundaries set by medical ethics that dictate the nurse's actions. This term does not directly relate to laws (choice A), common sense (choice C), or structure (choice D) in this context. The correct answer is 'B - Limits,' as it aligns with the idea of boundaries or restrictions within which the nurse must operate according to medical ethics.

3. In open-channel flow, a critical property is the free surface, which refers to the:

• A. Interface between the liquid and the container walls
• B. Interface between the liquid and a surrounding gas
• C. Bottom of the channel
• D. Region of highest velocity within the liquid

Correct answer: B

Rationale: The free surface in open-channel flow refers to the interface between the liquid and the surrounding gas, typically the atmosphere. This interface is critical as it determines the boundary between the liquid flow and the open environment. Option A is incorrect as it refers to the liquid-container wall interface, not the free surface. Option C is incorrect because it represents the bottom of the channel, not the free surface. Option D is incorrect as it describes the region of highest velocity within the liquid, not the free surface. Therefore, the correct choice is B.

4. What is 54% of $789.56?

• A. $426.36
• B. $426.37
• C. $363.20
• D. $526.38

Correct answer: A

Rationale: To calculate 54% of $789.56, you multiply 0.54 by 789.56, which equals $426.36. Therefore, choice A, $426.36, is the correct answer. Choice B, $426.37, is incorrect as it is a slightly higher value. Choice C, $363.20, is incorrect as it is significantly lower than the correct answer. Choice D, $526.38, is incorrect as it is higher than the correct calculation result.

5. Which, if any, of the following statements are true?

• A. Water boils at approximately 100°C (212°F) at standard atmospheric pressure
• B. The boiling point is the temperature at which the vapor pressure is higher than the atmospheric pressure around the water
• C. Water boils at a lower temperature in areas of lower pressure
• D. A and C are true

Correct answer: D

Rationale: Both statements A and C are true. Water indeed boils at approximately 100°C (212°F) at standard atmospheric pressure. However, water boils at a lower temperature in areas of lower pressure due to the decreased atmospheric pressure, which affects the vapor pressure and boiling point of water. Statement B is incorrect because the boiling point is the temperature at which the vapor pressure equals the external pressure (atmospheric pressure in this case), not when it is higher.
