HESI A2 Reading Comprehension Practice Test

1. What does the word 'obligatory' mean in the context of the passage on Daylight Savings Time?

A. Approved.
B. Sparse.
C. Requisite.
D. Aberrant.

Correct answer: C

Rationale: In the passage, Daylight Savings Time is presented as something that must be done by law, making it a requirement or something obligatory. 'Requisite' fits this meaning. 'Approved' (choice A) does not convey the sense of necessity as 'obligatory' does. 'Sparse' (choice B) means thinly dispersed and does not relate to the context. 'Aberrant' (choice D) means deviating from the norm, which is not applicable in this context.

2. The passage mentions all of these uses for microscopy EXCEPT ___________.

A. Ear surgery
B. Amputations
C. Vasectomies
D. Reconstructions

Correct answer: C

Rationale: The correct answer is C. The passage discusses various uses of microscopy in surgery, including ear surgery, amputations, and reconstructions. However, vasectomies are not mentioned as an application of microscopy in the text. Therefore, vasectomies are the exception among the listed uses. Choices A, B, and D are supported by details in the extract, making them incorrect answers. The passage highlights the uses of microscopy in delicate ear operations, repairing blood vessels in partially amputated limbs, and improving breast reconstructions. While vasectomies are mentioned briefly in the extract, they are not connected to the application of microscopy in the context of surgeries.

3. What is the meaning of the word 'composed' in the first paragraph?

A. To consist of

D. To be surprised

Correct answer: A

Rationale: In the context provided, 'composed' means to consist of. The paragraph explains that a drop of water is composed of an oxygen atom and two hydrogen atoms. Therefore, the correct answer is A. Choice B, 'To be uniquely discovered,' is incorrect as it does not relate to the composition of a drop of water. Choice C, 'To be set apart,' and Choice D, 'To be surprised,' are also incorrect as they do not convey the meaning of 'composed' as it is used in this paragraph.
