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. What is a major difference in the way baroreceptors and chemoreceptors work from the way the kidneys work?

• A. Baroreceptors and chemoreceptors send impulses from the arteries, while the kidneys control blood volume.
• B. Baroreceptors and chemoreceptors both work to help maintain blood volume, whereas the kidneys take care of salts, water, and waste removal.
• C. Baroreceptors and chemoreceptors must work together to control blood pressure, whereas the kidneys work with the adrenal cortex.
• D. Baroreceptors and chemoreceptors are both located near the adrenal cortex, whereas the kidneys are located near the heart.

Correct answer: A

Rationale: The correct answer is A. Baroreceptors and chemoreceptors send impulses from the arteries, while the kidneys control blood volume. Baroreceptors and chemoreceptors are responsible for monitoring blood pressure by sensing changes in pressure, oxygen levels, carbon dioxide levels, and pH within the arteries. They send out impulses to raise or lower blood pressure accordingly. On the other hand, the kidneys play a crucial role in regulating blood volume by absorbing salts and water and removing waste products. This key difference highlights that while baroreceptors and chemoreceptors are involved in monitoring and regulating blood pressure, the kidneys primarily focus on controlling blood volume. Choice B is incorrect because it inaccurately states that baroreceptors and chemoreceptors help maintain blood volume, which is not their primary function. Choice C is incorrect as it provides an inaccurate comparison between the roles of baroreceptors, chemoreceptors, and the kidneys. Choice D is incorrect as it wrongly associates the location of baroreceptors and chemoreceptors with the adrenal cortex, which is not accurate.

3. What was the author's motive for writing the paragraph?

• A. Encourage overeating.
• B. Criticize healthy eating habits.
• C. Urge self-control.
• D. Promote exercise.

Correct answer: C

Rationale: The author's motive for writing the paragraph is to urge self-control. The text emphasizes the importance of moderation in food and drink consumption to avoid serious physical and mental health problems. It highlights the negative consequences of overeating and alcohol abuse, pointing out the strain on the heart, diabetes risk, shortened lifespan, and emotional eating habits. By discussing the issues related to overconsumption, the author aims to promote self-control and responsible habits. Choices A, B, and D are incorrect because the paragraph focuses on advocating moderation and self-discipline rather than encouraging overeating, criticizing healthy eating habits, or promoting exercise.

4. Which of the following describes the purpose of the passage?

• A. To describe the causes of cystic fibrosis
• B. To explain how cystic fibrosis is passed down through families
• C. To provide an overview of CF and how it is inherited
• D. To review why some Americans have CF, but others do not

Correct answer: C

Rationale: The correct answer is C. The passage aims to provide an overview of cystic fibrosis (CF) and how it is inherited. It explains that CF is passed down through families due to a defective gene, detailing how this gene affects the body and who is most commonly affected by the disease. Choices A, B, and D are incorrect because the passage does not solely focus on describing the causes of CF, explaining how it is passed down through families, or reviewing why some Americans have CF while others do not. Instead, it provides a broader perspective on CF and its inheritance.

5. Which statement could be inferred by the reader from the last paragraph of the passage?

• A. Procedures that Lifewings Partners recommends are always effective.
• B. Medical mistakes can happen at even the best hospitals.
• C. City hospitals know more than others about cutting-edge medicine.
• D. Medical mistakes will one day be completely eradicated.

Correct answer: B

Rationale: The inference that medical mistakes can happen even at reputable hospitals is suggested by the warning from Steve Harden about the risks involved. The passage acknowledges that even well-regarded facilities are not immune to errors, thereby supporting option B as a logical conclusion drawn from the text.
