HESI A2 Reading Comprehension V1 2024 Questions
Question 1 of 5
What is the meaning of the word 'sterile' as it is used in the second paragraph?
Correct Answer: A
Rationale: The correct answer is A: free of bacteria. In the context of the second paragraph, the word 'sterile' is most likely referring to the cleanliness and lack of bacteria in the environment. This is supported by the fact that the paragraph is discussing medical equipment and the importance of maintaining sterility to prevent infection. Choice B, healthy, is incorrect as 'sterile' does not necessarily mean healthy. Choice C, delicious, is unrelated to the context and does not make sense. Choice D, impotent, is also unrelated and does not fit the context of the paragraph.
Question 2 of 5
What is the meaning of the word 'evolved' in the first paragraph?
Correct Answer: B
Rationale: The correct answer is B. In the context of the first paragraph, 'evolved' refers to a gradual development or change over time. This is supported by the mention of changes and advances in technology. 'To spread' (A) does not capture the idea of development, 'revolve' (C) means to rotate around a central point, and 'shift' (D) implies a sudden or abrupt change, which does not align with the gradual nature of evolution in this context.
Question 3 of 5
What is the meaning of the word 'composed' in the first paragraph?
Correct Answer: A
Rationale: The correct answer is A: To consist of. In the context of the first paragraph, 'composed' refers to the elements or parts making up something. The word implies that something is made up of different components. This is evident as the paragraph discusses how the team is composed of individuals with diverse skills and backgrounds. Explanation of why other choices are incorrect: B: To be uniquely discovered - This does not fit the context of the paragraph which is describing the makeup of a team. C: To be set apart - This does not align with the meaning of 'composed' in the context of being made up of different parts. D: To be surprised - This has no relevance to the meaning of 'composed' in the paragraph.
Question 4 of 5
What is the meaning of the word 'technical' as it is used in the fourth paragraph?
Correct Answer: A
Rationale: The correct answer is A: requiring expert knowledge. In the fourth paragraph, the word 'technical' is used in the context of needing specific expertise or skill. The term 'technical' often refers to specialized knowledge or proficiency in a particular field. In this case, the text suggests that a certain level of expertise is necessary to understand or perform the task mentioned. Explanation for why the other choices are incorrect: B: Incomplete - This choice does not align with the context in the paragraph. The word 'technical' does not imply incompleteness, but rather a need for specialized knowledge. C: Foreign - The word 'technical' does not indicate something foreign or unfamiliar, but rather something requiring expertise. D: Plagiarized - This choice is unrelated to the meaning of 'technical' in the context. 'Plagiarized' refers to copying someone else's work without permission, which is not relevant to the paragraph's discussion of expertise.
Question 5 of 5
What are the three steps of the 'wave of excitation'?
Correct Answer: D
Rationale: The correct answer is D because it accurately describes the three steps of the 'wave of excitation' in the heart. 1. The excitation of the atrium: This step involves the initiation of the electrical signal in the atria, leading to their contraction. 2. The excitement of the ventricle: Following the excitation of the atrium, the electrical signal spreads to the ventricles, causing them to contract. 3. The relaxing of the ventricle: Once the ventricles have contracted and ejected blood, they then relax in preparation for the next cardiac cycle. Choice A is incorrect because it mentions the peak ECG, which is not a step in the 'wave of excitation.' Choice B is incorrect as it includes systemic neural response, which is not part of the electrical conduction pathway. Choice C is incorrect as it describes the contraction and relaxation of the atrium only, missing the crucial step of ventricular excitation.
