HESI A2 Reading Comprehension 2024
1. What is the meaning of the word delicate as used in the first paragraph?
- A. Subtle
- B. Fragile
- C. Refined
- D. Intricate
Correct answer: D
Rationale: In the context of microsurgery, the word 'delicate' refers to the intricate, precise, and fine nature of surgeries performed using microscopy. These surgeries require intricate attention to detail and precision due to the small and delicate structures involved, making 'intricate' the most appropriate synonym. 'Subtle' implies understated or not obvious, 'fragile' suggests easily broken or damaged, and 'refined' refers to something developed or improved over time, none of which fully capture the detailed and precise nature of microsurgery. Therefore, 'intricate' is the correct answer.
2. What is the meaning of the word 'enlist' as it is used in the second paragraph?
- A. call into service
- B. write down
- C. send away
- D. put across
Correct answer: A
Rationale: In the context of the immune system, 'enlist' means to call into service. Immune cells recruit other cells to fight infection by producing chemicals that regulate their growth, behavior, and direct new recruits to trouble spots. This process is essential for the immune system's defense mechanism. The other choices are incorrect: 'write down' and 'put across' do not capture the action of mobilizing immune cells, and 'send away' is opposite in meaning to what is happening in the immune response.
3. What is the meaning of the word overturn in the last paragraph of the passage?
- A. Justify
- B. Invalidate
- C. Support
- D. Review
Correct answer: B
Rationale: The word "overturn" means to invalidate or negate existing guidelines. In this context, the passage questions whether the findings of the study are substantial enough to change established medical recommendations regarding caffeine intake during pregnancy, making option B the appropriate choice.
4. In this passage, which of the following is not mentioned as a role of HGH in the human body?
- A. Regulating the metabolism.
- B. Stimulating the immune system.
- C. Regulating leptin, an appetite-controlling hormone.
- D. Facilitating calcium retention.
Correct answer: C
Rationale: The correct answer is C: Regulating leptin, an appetite-controlling hormone. In the provided passage, it is stated that human growth hormone (HGH) is essential for regulating metabolism, building muscle, facilitating calcium retention, and stimulating the immune system. However, leptin is not mentioned as directly regulated by HGH. Instead, the passage discusses how inadequate sleep can lead to lowered levels of leptin, affecting appetite control. Choices A, B, and D are all roles of HGH explicitly mentioned in the passage, making them incorrect answers. Therefore, C is the correct choice as it was not directly linked to HGH in the passage.
5. Choose the best summary of the passage.
- A. We often think of all fat as bad, but it is clear that certain fats, especially the more healthful unsaturated fats, are important for bodily function.
- B. If you must consume some fat, be sure to choose unsaturated fats such as oils rather than saturated fats found in prepackaged snacks or animal products.
- C. Doctors and researchers have discovered that without the calories found in fat, people would not have functioning metabolisms.
- D. Some intake of saturated fat is necessary, but you should stay away from the kind of fat found in fried food, which can lead to heart disease.
Correct answer: A
Rationale: The best summary of the passage emphasizes the importance of certain fats, particularly unsaturated fats, for bodily function. It highlights that after years of negative publicity, experts now recognize the significance of consuming fats for overall health. The passage discusses how fat is essential for cell health, vitamin absorption, and various bodily functions. It also distinguishes between healthier unsaturated fats like olive oil and detrimental trans fats. Choice B is not the best summary as it focuses more on the choice between unsaturated and saturated fats rather than the overall importance of fats. Choice C is incorrect as the passage doesn't solely attribute functioning metabolisms to fat calories. Choice D is not the best summary as it only briefly mentions saturated fats and fried foods, missing the broader context provided in the passage.
