HESI A2 Reading Comprehension V1 2024
1. What is the meaning of the word 'sterile' as it is used in the second paragraph?
- A. free of bacteria
- B. healthy
- C. delicious
- D. impotent
Correct answer: A
Rationale: In the context provided, 'sterile' means free of bacteria. The text mentions that raw foods are not sterile and can be a common source of foodborne illnesses due to contamination with harmful bacteria. 'Healthy' (choice B) is incorrect as the term 'sterile' specifically refers to the absence of bacteria, not overall health. 'Delicious' (choice C) is irrelevant to the context of bacteria contamination. 'Impotent' (choice D) is also incorrect as it does not relate to the concept of being free from bacteria.
2. What is the meaning of the word 'emitting' as it is used in the second paragraph?
- A. Repelling
- B. Releasing
- C. Closing
- D. Charging
Correct answer: B
Rationale: In the context provided, 'emitting' means releasing, specifically referring to the electric currents being released in the body. The passage describes how electric currents are constantly being emitted in the body and can be detected on the body's surface, ultimately recorded by an electrocardiograph. This process is about the release of electric impulses, making 'releasing' the correct interpretation. Choice A, 'Repelling,' implies pushing away, which is not the intended meaning in this context. Choice C, 'Closing,' and Choice D, 'Charging,' do not align with the context of electric currents being emitted.
3. What is the meaning of the word 'deceptive' as it is used in the fifth paragraph?
- A. misleading
- B. malicious
- C. illegal
- D. irritating
Correct answer: A
Rationale: In the context provided, 'deceptive' means misleading. The passage discusses how the Federal Trade Commission (FTC) regulates product advertising to ensure that all information is truthful and not misleading. Therefore, the correct answer is 'A: misleading.' Choice B, 'malicious,' is incorrect as it implies harmful intent, which is not necessarily conveyed by the term 'deceptive' in this context. Choice C, 'illegal,' is incorrect because 'deceptive' does not solely refer to something being against the law, but rather to misleading information. Choice D, 'irritating,' is also incorrect as it does not capture the essence of 'deceptive' as used in the passage.
4. What is the meaning of the word 'ideal' as it is used in the first paragraph?
- A. thoughtful
- B. confined
- C. hostile
- D. perfect
Correct answer: D
Rationale: In this context, 'ideal' means perfect. The human body provides a perfect environment for many microbes, as stated in the extract. It is the immune system's role to keep these microbes out or destroy them. The other choices are incorrect: 'thoughtful' does not fit the context of the sentence, 'confined' and 'hostile' are not synonymous with 'ideal' in this context.
5. What is the meaning of the word 'enlist' as it is used in the second paragraph?
- A. call into service
- B. write down
- C. send away
- D. put across
Correct answer: A
Rationale: In the context of the immune system, 'enlist' means to call into service. Immune cells recruit other cells to fight infection by producing chemicals that regulate their growth, behavior, and direct new recruits to trouble spots. This process is essential for the immune system's defense mechanism. The other choices are incorrect: 'write down' and 'put across' do not capture the action of mobilizing immune cells, and 'send away' is opposite in meaning to what is happening in the immune response.
