HESI A2 Reading Comprehension Practice Test
1. 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.
2. What are the three steps of the 'wave of excitation'?
- A. The discharge from the SA node, the peak ECG, and the excitement of the ventricle.
- B. The excitement of the ventricle, the relaxing of the ventricle, and the systemic neural response.
- C. The contraction of the atrium, the relaxation of the atrium, and the contraction of the ventricle.
- D. The excitation of the atrium, the excitement of the ventricle, and the relaxing of the ventricle.
Correct answer: D
Rationale: The correct steps of the 'wave of excitation' are the excitation of the atrium, excitement of the ventricle, and relaxation of the ventricle. In the described process, the 'wave of excitation' starts with the discharge from the SA node, leading to the excitation of the atrium. Next, the peak ECG corresponds to the excitement of the ventricle, not its relaxation. Finally, the wave concludes with the relaxation of the ventricle, not its contraction. Therefore, choices A, B, and C are incorrect as they do not accurately describe the sequential steps of the 'wave of excitation' as presented in the extract.
3. Which might be a good title for this passage?
- A. “Everyone Should Run Barefoot”
- B. “How to Prevent Running Injuries”
- C. “Modern Road Surfaces Versus Barefoot Running”
- D. “The Debate over Barefoot Running”
Correct answer: D
Rationale: The title "The Debate over Barefoot Running" encapsulates the central theme of the passage, which explores both the advantages and disadvantages of barefoot running. It effectively summarizes the discussions around differing opinions and the lack of consensus on this topic. Other titles do not accurately reflect the primary focus of the essay, making D the most suitable choice.
4. What is the meaning of the word conform as used in the first paragraph?
- A. Authorize
- B. Fit in
- C. Hand over
- D. Bewilder
Correct answer: B
Rationale: In this context, "conform" means to fit in with societal norms or standards, particularly those related to beauty. The passage describes how individuals may compromise their health to meet these cultural ideals, indicating that conformity relates to adhering to social expectations of beauty, making option B the correct interpretation.
5. Which of the following is not mentioned as a detail in the passage about Sickle-Cell Anemia?
- A. People of South American or African descent may be prone to sickle-cell anemia.
- B. Symptoms of sickle-cell anemia may include sudden occurrences of extreme abdominal and back pain.
- C. The red blood cells of sickle-cell patients are unusually shaped, forming crescent or sickle shapes.
- D. Vitamin and mineral deficiencies may result in some anemia.
Correct answer: D
Rationale: The correct answer is D because the passage does not mention anything about vitamin and mineral deficiencies in relation to sickle-cell anemia. Choice A is incorrect as the passage specifies that sickle-cell anemia is more common among people of South American or African descent. Choice B is correct as the passage states that symptoms of sickle-cell anemia can include sudden occurrences of extreme abdominal and back pain. Choice C is correct as the passage describes that the red blood cells of sickle-cell patients are unusually shaped, forming crescent or sickle shapes. The passage does not discuss any relationship between vitamin and mineral deficiencies and sickle-cell anemia, making choice D the correct option.
