HESI A2

Reading Comprehension HESI A2

1. What body of water does The Golden Gate Bridge cross?

A. San Francisco Bay
B. Pacific Ocean
C. Marin Strait
D. Indian Ocean

Correct answer: A

Rationale: The Golden Gate Bridge crosses the entrance to San Francisco Bay, spanning the Golden Gate Strait. It does not cross the Pacific Ocean, Marin Strait, or Indian Ocean directly. The iconic bridge connects the city of San Francisco to Marin County in California. The Pacific Ocean is a vast body of water beyond the Golden Gate entrance, and Marin Strait is not a recognized geographical location. The Indian Ocean is located on a different continent and is not related to the Golden Gate Bridge's location.

2. What does Macmillan's invention of the bicycle signify?

A. He made important changes in bicycle design.
B. He invented the first bicycle with pedals.
C. He developed the modern chain drive.
D. He improved the safety of bicycles.

Correct answer: B

Rationale: Macmillan's invention of pedals was a significant milestone in bicycle history as it allowed for quicker and more efficient travel. The provided extract mentions that Macmillan's bicycle had foot-operated cranks like pedals, which enabled the rider to travel at a quick pace. This innovation marked a crucial development in the evolution of bicycles. While choices A, C, and D are related to advancements in bicycle design and safety, the key significance of Macmillan's invention lies in introducing pedals to bicycles, making choice B the correct answer.

3. What is implied by this paragraph about food and drink?

A. We should eat and drink in reasonable quantities.
B. Alcohol should be banned.
C. People should eat in large quantities.
D. We need stronger laws to control drunk drivers.

Correct answer: A

Rationale: The paragraph emphasizes that while food and drink are necessary and desirable, their abuse can lead to serious physical and mental problems. It highlights the negative consequences of overeating and alcohol abuse, such as strain on the heart, diabetes, and other health issues. The text suggests the importance of moderation in consumption to prevent health problems. Choices B, C, and D are incorrect because the paragraph does not call for a ban on alcohol, promote eating in large quantities, or specifically discuss the need for stronger laws to control drunk drivers.

4. Which of the following is not listed as a detail in the passage about Yoga?

A. Improved circulation.
B. Strengthening of core muscles.
C. Stress reduction.
D. Fortification of immune system.

Correct answer: D

Rationale: The passage outlines several benefits of yoga, such as improved circulation, strengthened core muscles, and reduced stress. However, it does not mention the fortification of the immune system, which is not discussed in the context of the benefits of yoga. This makes D the correct answer, as it is the only option not supported by the passage.

5. 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.
