HESI A2 Reading Comprehension

1. The word 'track' as used in the last paragraph of the passage can best be defined as ___________.

A. Keep a record of
B. A new attitude
C. Follow carefully
D. A paved, circular path

Correct answer: D

Rationale: In the context of the passage, 'track' refers to a 'paved, circular path' for running or walking. The last sentence of the passage encourages people to get off the couch and onto the track, indicating a physical path for exercise. Choice A, 'Keep a record of,' is incorrect as the context does not suggest any relation to recording information. Choice B, 'A new attitude,' is unrelated to the context of exercise and fatigue reduction. Choice C, 'Follow carefully,' does not fit the context of physical activity and energy levels discussed in the passage.

2. What statement about global warming is made in the passage on the Amazon Rainforest?

A. Global warming is caused by deforestation.
B. Global warming is unrelated to deforestation.
C. Global warming is exaggerated.
D. Global warming is not a concern.

Correct answer: A

Rationale: The correct statement about global warming in the passage on the Amazon Rainforest is that it is caused by deforestation. The passage explains that cutting down trees in the rainforest increases the amount of carbon dioxide in the air, leading to global warming. This is supported by the fact that the burning of Brazilian rainforests alone produces 200 million metric tons of carbon dioxide a year. Choice B is incorrect as the passage clearly establishes a direct link between deforestation and global warming. Choice C is incorrect as the passage does not suggest that global warming is exaggerated, but rather highlights the harmful effects of deforestation. Choice D is incorrect as the passage emphasizes the serious concern of global warming due to deforestation.

3. What is the best summary of the passage?

A. Electric currents within the body are due to electrostatic charges set off by the heart. Medical staff are trained to recognize any abnormalities within the heart.
B. Every individual has unique electric currents on the surface of the body. The ECG measures and records these electric currents.
C. The ECG systematically and rather quickly measures the stages at which the 'wave of excitation' occurs within the heart and records them. This wave has three distinct steps that spread from the SA node to the AV node.
D. The ECG measures the electric currents within the body. These currents are detected on the surface of the body when the body is connected to an amplifier.

Correct answer: C

Rationale: The correct summary of the passage is option C. The passage explains how the ECG systematically measures and records the 'wave of excitation' that occurs within the heart in three distinct steps, spreading from the SA node to the AV node. This summary effectively captures the main focus of the passage. Option A is incorrect because it only mentions the detection of electric currents in the body and recognizing abnormalities by medical staff, missing the key information about the 'wave of excitation' and its stages. Option B is incorrect as it focuses solely on the measurement and recording of unique electric currents on the body's surface, neglecting the specific process described in the passage. Option D is also incorrect as it provides a general description of how the ECG measures electric currents without emphasizing the specific stages of the 'wave of excitation' as detailed in the passage.

4. Which of the following is not listed as a detail in the passage about Aromatherapy?

A. Subjects were given mild stressors.
B. Lemon and lavender scents were tested.
C. Vanilla worked better than lemon for stress.
D. The study took place at Ohio State University.

Correct answer: C

Rationale: The passage does not support the idea that vanilla worked better than lemon for stress relief; instead, it focuses specifically on lemon and lavender as the tested scents. The absence of this information regarding vanilla makes C the correct answer, as it is not included in the details provided in the passage.

5. What is the author's main argument in the passage on the Electoral College?

A. The Electoral College ensures that all states have a say in elections.
B. The Electoral College is outdated and needs reform.
C. The Electoral College should be abolished.
D. The Electoral College was created to favor larger states.

Correct answer: B

Rationale: The correct answer is B: 'The Electoral College is outdated and needs reform.' The passage discusses the Electoral College system, highlighting its complexities and the discrepancy between the popular vote and electoral vote outcomes. It mentions the confusion and the case of the 2000 election where the popular vote winner did not become president. The main argument is that the system is outdated and requires reforms to align with modern democratic principles. Choice A is incorrect as the passage does not focus on ensuring all states have a say but rather on the need for reform. Choice C is not the main argument presented in the passage; while the passage mentions confusion, it does not explicitly call for abolition. Choice D is incorrect as the passage does not state that the Electoral College was created to favor larger states; instead, it discusses the allocation of electoral votes based on Congressional representation and population.
