Reading Comprehension HESI A2
1. What is implied by this paragraph?
- A. Overeating and alcohol abuse can lead to serious health issues.
- B. We should implement stricter laws to prevent alcohol abuse.
- C. Emotional eating is a major health concern.
- D. Consuming food and drinks in moderation is crucial.
Correct answer: A
Rationale: The paragraph implies that overeating and alcohol abuse can lead to serious physical and mental health problems. It highlights the strain on the heart, risk of diabetes, and shortened lifespan due to overeating. It also mentions the negative consequences of alcohol abuse, such as alcoholism, drunk driving leading to accidents, and spousal/child abuse. While emotional eating is mentioned, the main focus is on the health risks of overeating and alcohol abuse. Therefore, choice A is the correct answer as it captures the essence of the paragraph's message.
2. What is the main idea of the passage about Toxins and Your Health?
- A. Environmental toxins may have dire health effects over time.
- B. Of three toxins studied, lead has the worst effect on health.
- C. Toxins may accumulate in the bones of older patients.
- D. Johns Hopkins University has discovered a new use for lead.
Correct answer: A
Rationale: The passage emphasizes the long-term effects of environmental toxins such as lead, pesticides, and mercury on brain health, particularly as individuals age. Dr. Brian Schwartz's quote highlights the link between environmental exposure and cognitive decline, framing the entire discussion around the potential health ramifications of such exposure over time. This clearly aligns with choice A, making it the main idea of the passage.
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. What conclusion can be drawn from the passage on bicycles?
- A. Bicycles have been evolving for centuries.
- B. Bicycles have evolved significantly over time.
- C. Bicycles have remained unchanged since their invention.
- D. Bicycles are no longer a popular means of transportation.
Correct answer: B
Rationale: The correct conclusion that can be drawn from the passage is that bicycles have evolved significantly over time. The passage discusses the evolution of bicycles from their early wooden, pedal-less designs to the modern safety bicycle with equal-sized wheels and chain-driven pedals. Each inventor mentioned in the passage contributed to significant improvements in bicycle design, making them more efficient and popular for transportation and recreation. Choice A is incorrect because the passage does not mention bicycles evolving continuously for centuries, but rather highlights specific innovations over time. Choice C is incorrect as the passage clearly describes the various improvements and changes made to bicycles since their invention. Choice D is also incorrect as the passage emphasizes the continued popularity and usefulness of bicycles for transportation all over the world.
5. Which of the following is a conclusion that a reader can draw from this passage?
- A. Humans are not the only mammals that exhibit symptoms when infected by Borrelia burgdorferi.
- B. The life cycle of an uninfected tick includes a dormant phase before the nymph stage, which is not excluded.
- C. Unless a tick feeds on an infected mouse or squirrel, it will not spread Lyme disease.
- D. The combination of fever, headache, and joint pain is not a definite indication of Lyme disease.
Correct answer: C
Rationale: The correct answer is C. The passage clearly states that for Lyme disease to spread, a tick must feed on an infected host, such as a mouse or squirrel. This conclusion can be drawn from the information provided in the extract. Choice A is incorrect because the passage does not specify that humans are the only mammals that exhibit symptoms when infected by Borrelia burgdorferi. Choice B is incorrect as the passage mentions that the life cycle of an uninfected tick includes a dormant phase before the nymph stage, without excluding it. Choice D is incorrect because the passage does not state that the combination of fever, headache, and joint pain is a definitive sign of Lyme disease.
