HESI A2

Reading Comprehension HESI A2

1. In the passage the word embark means to:

A. Remove the covering from a tree
B. Speak harshly to others
C. Entertain the reader
D. Put or go on board a ship

Correct answer: D

Rationale: The word 'embark' typically means to board a ship or begin a journey. In this context, it means to start or set out on a new undertaking or venture, often including the act of boarding a ship. In the provided passage about the Golden Gate Bridge, it is mentioned that builders, architects, and workers embarked on the challenge of building a bridge across the Golden Gate Strait, which refers to them starting this new undertaking. Therefore, the correct definition of 'embark' is D. Put or go on board a ship. The other choices are incorrect: A. Removing the covering from a tree is unrelated to the context of the passage. B. Speaking harshly to others and C. Entertaining the reader are also irrelevant to the meaning of 'embark' in this context.

2. 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.

3. What is the author’s primary purpose in writing the essay?

A. To persuade the reader to have an ECG
B. To entertain the reader with a heartwarming story
C. To inform the reader how an electrocardiograph reads the electric currents emitted by the heart
D. To analyze the difference between the SA node and the AV node

Correct answer: C

Rationale: The author's primary purpose in writing the essay is to inform the reader about how an electrocardiograph reads the electric currents emitted by the heart. Choice A is incorrect because there is no attempt to persuade the reader to have an ECG. Choice B is incorrect because the essay is focused on providing information rather than entertaining with a heartwarming story. Choice D is incorrect as the essay does not primarily analyze the difference between the SA node and the AV node; instead, it focuses on explaining how an electrocardiograph reads electric currents from the heart.

4. What is the meaning of the word 'emitting' as it is used in the second paragraph?

A. Repelling
B. Releasing
C. Closing
D. Charging

Correct answer: B

Rationale: In the context provided, 'emitting' means releasing, specifically referring to the electric currents being released in the body. The passage describes how electric currents are constantly being emitted in the body and can be detected on the body's surface, ultimately recorded by an electrocardiograph. This process is about the release of electric impulses, making 'releasing' the correct interpretation. Choice A, 'Repelling,' implies pushing away, which is not the intended meaning in this context. Choice C, 'Closing,' and Choice D, 'Charging,' do not align with the context of electric currents being emitted.

5. What is the meaning of the word 'popular' as it is used in the third paragraph?

A. complicated
B. old-fashioned
C. beloved
D. for the general public

Correct answer: D

Rationale: In the context provided, 'popular' refers to magazines intended for the general public. The paragraph mentions that Infotrac indexes hundreds of popular magazines and newspapers, including medical journals such as the Journal of the American Medical Association and New England Journal of Medicine. These magazines target a wide audience, making choice D ('for the general public') the correct answer. Choices A, B, and C are incorrect as they do not align with the context of the paragraph.
