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 best summary of the passage?
Correct Answer: C
Rationale: The correct answer is C because it accurately summarizes the key points of the passage about the ECG. It mentions that the ECG measures the stages of the 'wave of excitation' within the heart and its three distinct steps. It also describes how this wave spreads from the SA node to the AV node. Choice A is incorrect because it focuses on electrostatic charges set off by the heart, which is not the main focus of the passage. Choice B is incorrect because it talks about unique electric currents on the surface of the body, which is not the main purpose of the ECG as mentioned in the passage. Choice D is incorrect because it only mentions that the ECG measures electric currents within the body without providing the specifics of the wave of excitation and its stages as described in the passage.
Question 3 of 5
Which sound waves have a higher pitch?
Correct Answer: A
Rationale: The correct answer is A because sound pitch is determined by the frequency of sound waves. When waves are closer together, they have a higher frequency, resulting in a higher pitch. In contrast, when waves are farther apart, the frequency is lower, leading to a lower pitch. Choices B, C, and D are incorrect as they do not directly relate to the frequency of sound waves, which is the key factor affecting pitch.
Question 4 of 5
What is the meaning of the word 'phenomenon' in the second paragraph?
Correct Answer: C
Rationale: The correct answer is C: Something that is significant but unusual. In the context of the second paragraph, the word 'phenomenon' is used to describe something that is noteworthy and out of the ordinary. It implies that the subject being discussed is unique or remarkable. Choices A, B, and D are incorrect because they do not capture the essence of 'phenomenon' as being both significant and unusual. Option A focuses on being lifeless, B on nonchalant behavior, and D on chemical origin, none of which align with the meaning of 'phenomenon' in this specific paragraph.
Question 5 of 5
What is the meaning of the word 'elasticity' in the last paragraph?
Correct Answer: A
Rationale: The correct answer is A: Something that is able to resist and be flexible. In the context of elasticity, it refers to the ability of a material to return to its original shape after being stretched or compressed. This aligns with the concept of resistance and flexibility. Choice B is incorrect as elasticity is not related to being like plastic. Choice C is incorrect as it does not capture the essence of elasticity being about resistance and flexibility. Choice D is incorrect as silliness has no relation to the concept of elasticity.
