HESI A2 Reading Comprehension

1. FRAX takes into account all of the following factors EXCEPT ___________.

A. Lifestyle choices
B. Exposure to toxins
C. Genetic heritage
D. Exposure to sunlight

Correct answer: B

Rationale: FRAX, a tool used to assess fracture risk, considers various factors like lifestyle choices, genetic heritage, and exposure to sunlight. However, exposure to toxins is not mentioned in the provided extract as a factor considered by FRAX. Therefore, the correct answer is B. Exposure to toxins is unrelated to fracture risk assessment as per the information provided. Lifestyle choices, genetic heritage, and exposure to sunlight are all factors that FRAX takes into consideration to determine the risk of experiencing a fracture within the next decade.

2. What does 'deteriorating' mean?

A. Improving
B. Worsening
C. Staying the same
D. Fluctuating

Correct answer: B

Rationale: The correct answer is B, 'Worsening.' Deteriorating refers to something getting worse over time, not improving (choice A), staying the same (choice C), or fluctuating (choice D).

3. Which sentence is written correctly?

A. Because she was uncertain of her abilities, Renee asked for help.
B. Because she was uncertain of her abilities; Renee asked for help.
C. Because she was uncertain of her abilities, Renee asked for help.
D. Because she was uncertain of her abilities, Renee asked for help.

Correct answer: A

Rationale: The correct sentence is 'Because she was uncertain of her abilities, Renee asked for help.' This sentence uses a comma after the introductory phrase 'Because she was uncertain of her abilities' to set it off from the main clause 'Renee asked for help.' The comma helps to separate the two parts of the sentence clearly and indicates the pause that should be there when reading it aloud. Options B, C, and D are incorrect because they either use a semicolon incorrectly or have commas placed incorrectly within the sentence.

4. If the sound of the bells could be heard in the entire community, then they could be heard __________.

A. Thorough
B. Thought
C. Through
D. Throughout

Correct answer: D

Rationale: The word 'throughout' means in every part of a place or thing. In this context, if the sound of the bells could be heard in the entire community, then it implies that the sound could be heard throughout the community, making 'Throughout' the most appropriate answer. Choice A 'Thorough' means complete or absolute, which does not fit the context of the sentence. Choice B 'Thought' is a past tense form of the verb 'think,' which is grammatically incorrect in this sentence. Choice C 'Through' is a preposition and does not convey the intended meaning of being heard in every part of the community.

5. How does asexual reproduction differ from sexual reproduction?

A. asexual reproduction results in all cells being identical to the original cell; sexual reproduction results in half of the cells being identical to the original cell
B. asexual reproduction results in two cells that contribute genetic material to daughter cells, resulting in significantly greater variation
C. sexual reproduction involves two cells that contribute genetic material to daughter cells, resulting in significantly greater variation
D. sexual reproduction involves one cell that yields all cells produced to be identical

Correct answer: C

Rationale: Sexual reproduction involves two cells (gametes) that contribute genetic material to daughter cells, resulting in significantly greater genetic variation in the offspring. This genetic variation is essential for evolution and adaptation to environmental changes. In contrast, asexual reproduction involves one cell dividing to produce offspring that are genetically identical to the parent cell. Choice A is incorrect because sexual reproduction does not result in half of the cells being identical to the original cell; it involves two cells contributing genetic material. Choice B is incorrect because asexual reproduction does not result in significantly greater variation; it produces genetically identical offspring. Choice D is incorrect because sexual reproduction involves two cells contributing genetic material, not one cell yielding all identical cells.
