Reading Comprehension Practice Test HESI A2

1. What is the main idea of the passage about Toxins and Your Health?

Correct answer: A

Rationale: The passage emphasizes the long-term effects of environmental toxins such as lead, pesticides, and mercury on brain health, particularly as individuals age. Dr. Brian Schwartz's quote highlights the link between environmental exposure and cognitive decline, framing the entire discussion around the potential health ramifications of such exposure over time. This clearly aligns with choice A, making it the main idea of the passage.

2. What is the main idea of the passage about MRSA?

Correct answer: D

Rationale: The main idea of the passage is that MRSA is a significant issue both within and outside of hospitals. It highlights the challenges posed by MRSA, including its resistance to antibiotics, high mortality rates, and widespread presence in various settings. While the development of new technologies like nanomaterial textiles shows promise in reducing hospital-associated MRSA, the passage also emphasizes the importance of practicing good hygiene to prevent community-associated MRSA infections. Choices A, B, and C are incorrect because they do not capture the comprehensive overview of MRSA provided in the passage. Choice A encompasses the main idea by emphasizing the significance of MRSA and ways to mitigate the risk. Choice B focuses on a specific solution rather than the broader issue of MRSA. Choice C is incorrect as it oversimplifies the risks associated with MRSA strains by only mentioning fatality.

3. What is the meaning of the word 'abstain' as used in the last paragraph?

Correct answer: B

Rationale: In the context of the passage, 'abstain' means to refrain from or go without. The passage discusses the challenges of treating individuals with both eating disorders and substance abuse issues. It mentions that while treatment for addiction involves abstinence, it is not possible to completely abstain from food. This highlights the meaning of 'abstain' as 'go without' in this context. The other choices are incorrect: 'Dishonor' does not relate to abstain, 'Connect to' is not synonymous with abstain, and 'Liberate' does not align with the context of the passage.

4. What is the meaning of the word 'booking' as used in the first paragraph?

Correct answer: A

Rationale: In this context, 'booking' refers to scheduling appointments for bone density tests. The correct choice is 'A: Scheduling' because in the given text, women are booking bone density tests to ensure their bone health. 'Contracting' (Choice B) is incorrect as it does not fit the context of making appointments. 'Traveling' (Choice C) and 'Charging' (Choice D) are also irrelevant to the context of scheduling appointments for medical tests.

5. Which sound waves have a higher pitch?

Correct answer: A

Rationale: Sound waves that are closer together have a higher pitch. This is explained by the Doppler Effect, where as a source of sound moves closer to an observer, the waves are compressed, resulting in a higher frequency and a higher pitch. Conversely, when the source moves away, the waves are stretched, leading to a lower frequency and a lower pitch. Therefore, choice A is correct. Choices B, C, and D are incorrect as they do not accurately describe the relationship between sound wave frequency and pitch.
