Reading Comprehension Practice Test HESI A2
1. What does the term elasticity mean, as used in the passage about Hypertension?
- A. Firmness.
- B. Compactness.
- C. Flexibility.
- D. Rigidity.
Correct answer: C
Rationale: Elasticity, as used in the passage about Hypertension, refers to the stretchiness or flexibility of blood vessels. The text mentions that blood vessels lose elasticity and stiffen as a person ages, indicating that they become less flexible. This eliminates choices A and D (Firmness and Rigidity) as the correct answers. Choice B (Compactness) is unrelated to the concept of elasticity in the context of blood vessels and is therefore incorrect. Understanding elasticity as the ability to stretch or flex helps in choosing flexibility as the correct answer.
2. Choose the best summary of the passage about High Fructose Corn Syrup.
- A. After extensive studies, scientists recommend removing HFCS from grocery products.
- B. A recent study on rats confirms suspicions that HFCS contributes to unhealthful weight gains.
- C. Until more research is done, using HFCS is preferable to replacing it with refined sugar.
- D. Avoiding HFCS can have immediate, healthful results on overweight patients, as suggested by the AMA.
Correct answer: B
Rationale: The best summary of the passage is choice B. The passage discusses concerns about the impact of high fructose corn syrup (HFCS) on health, particularly its link to obesity. It mentions a recent study on rats that confirms suspicions about HFCS contributing to unhealthful weight gains. Choices A, C, and D are incorrect as they introduce recommendations or implications not explicitly mentioned in the passage. Choice A goes beyond the information by stating that scientists recommend removing HFCS from grocery products, choice C suggests that using HFCS is preferable until more research is done, and choice D implies immediate healthful results on overweight patients by avoiding HFCS, as suggested by the AMA, which is not supported by the passage.
3. Which statement is not listed as a detail within the passage?
- A. Changes in the ECG are typically used for the diagnosis of abnormal cardiac rhythm.
- B. The signal has a characteristic record called the electrocardiogram.
- C. The 'wave of excitation' starts at the SA node.
- D. The 'wave of excitation' spreads through the heart wall and is accompanied by electric changes.
Correct answer: A
Rationale: The corrected statement should be: Changes in the ECG are not typically used for the diagnosis of abnormal cardiac rhythm. The passage mentions that the heart sends out electric currents in waves, and the 'wave of excitation' spreads through the heart wall accompanied by electric changes. It details the process of how the heart's electric impulses are recorded and how abnormalities can be detected. However, it does not state that ECG changes are specifically used for diagnosing abnormal cardiac rhythms. Choice A is the correct answer because it misrepresents the information provided in the passage. Choices B, C, and D are all supported by the passage and align with the details mentioned regarding the electrocardiogram and the wave of excitation in the heart.
4. What is the meaning of the word satiety as used in the last paragraph about The Sleep Workout?
- A. A state of tiredness.
- B. A state of being satisfied.
- C. A state of being overloaded.
- D. A state of confusion.
Correct answer: B
Rationale: Satiety refers to a state of being satisfied, particularly in terms of appetite. In the context of the excerpt provided, it explains that individuals who lack adequate sleep may experience lowered levels of leptin, a hormone that controls appetite. As a result, even after meeting their caloric needs, they may still crave carbohydrates, indicating a lack of satisfaction or satiety. This can lead to obesity and disrupt healthy eating habits. Therefore, choice B, 'A state of being satisfied,' is the correct answer. Choices A, C, and D are incorrect as they do not accurately reflect the meaning of satiety in the context of appetite regulation and sleep's impact on food cravings.
5. Which of the following is not listed as a detail in the passage about Yoga?
- A. Improved circulation.
- B. Strengthening of core muscles.
- C. Stress reduction.
- D. Fortification of immune system.
Correct answer: D
Rationale: The passage outlines several benefits of yoga, such as improved circulation, strengthened core muscles, and reduced stress. However, it does not mention the fortification of the immune system, which is not discussed in the context of the benefits of yoga. This makes D the correct answer, as it is the only option not supported by the passage.
