HESI A2 Reading Comprehension

1. Which statement could be inferred from the passage?

A. The Georgia lab had conducted a previous study on the connection between exercise and energy.
B. Exercise regimes are not recommended for patients with serious health problems.
C. An increase in energy levels does not always correspond directly to a reduction in fatigue.
D. There were fewer than 10 participants in each group in the Georgia study.

Correct answer: A

Rationale: The correct answer is A. The passage mentions a previous study by the same team on the connection between exercise and energy, indicating that the lab had conducted such research before. Choice B is incorrect because the passage actually states that low-impact exercise can help reduce fatigue in patients with serious health conditions. Choice C is incorrect as the passage indicates that an increase in energy levels does correspond to a reduction in fatigue. Choice D is incorrect as the passage does not provide information on the exact number of participants in each group.

2. Which of the following statements is an opinion related to MRSA?

A. Hand-washing stations are one means of combating MRSA infection.
B. Not all Staphylococcus bacteria are resistant to antibiotics.
C. Hospitals in the United States should quickly adopt the use of new germ-fighting textiles.
D. MRSA infection kills more people in the United States than does HIV/AIDS.

Correct answer: C

Rationale: The correct answer is C because it is an opinion rather than a verifiable fact. The statement suggests a recommendation for hospitals to adopt new germ-fighting textiles swiftly, which is a subjective viewpoint and not objectively measurable. Choices A and B are factual statements regarding combating MRSA infection and antibiotic resistance, respectively. Choice D provides a comparison of MRSA infection with HIV/AIDS, which is a factual statement based on statistical data. Therefore, C is the only choice that presents an opinion rather than a fact.

3. What does the passage about the Water Cycle explain?

A. The water cycle consists of precipitation, evaporation, and condensation.
B. The water cycle is a continuous process of recycling water on Earth.
C. Rain is the most important part of the water cycle.
D. Evaporation is the final step in the water cycle.

Correct answer: A

Rationale: The correct answer is A: 'The water cycle consists of precipitation, evaporation, and condensation.' The passage explains the stages of the water cycle, starting with precipitation (rain, snow, sleet, or hail) falling to the ground, followed by runoff, evaporation transforming liquid water into water vapor, and finally condensation turning water vapor back into liquid. Choice B is incorrect because it is too broad and doesn't specifically address the stages of the water cycle. Choice C is incorrect as rain is just one part of the water cycle and not the most important. Choice D is incorrect as evaporation is not the final step but one of the stages of the water cycle.

4. 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.

5. What is the meaning of the word 'technical' as it is used in the fourth paragraph?

A. requiring expert knowledge
B. incomplete
C. foreign
D. plagiarized

Correct answer: A

Rationale: The correct answer is 'A: requiring expert knowledge.' In the context provided, 'technical' refers to articles that demand expert knowledge to understand. The passage mentions that articles published in medical journals can be technical, meaning they are complex and require specialized expertise to comprehend. Choice B, 'incomplete,' is incorrect as 'technical' does not imply incompleteness. Choices C and D, 'foreign' and 'plagiarized,' are also incorrect as they do not align with the context of the passage.
