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. What is the meaning of the word exposed as used in the first paragraph about Toxins and Your Health?

A. Uncovered.
B. Subjected.
C. Visible.
D. Divulged.

Correct answer: B

Rationale: In the context of the passage, "exposed" means to be subjected to harmful elements. It suggests vulnerability to these toxins, which can lead to serious health issues later in life. The other options do not accurately capture the implications of "exposed" in relation to toxic substances, making B the correct choice.

3. Which statement from the passage on Voice is a fact rather than an opinion?

A. One of the worst voice qualities is harshness.
B. Harsh voice qualities come from tension in the throat.
C. Your voice will sound unpleasant if it is shrill or grating.
D. Because tension occurs in higher-pitched voices, women tend to have shriller voices than men.

Correct answer: B

Rationale: The correct answer is B. The fact that harsh voice qualities come from tension in the throat is a verifiable statement based on a scientific explanation provided in the passage. This statement is not subject to personal interpretation or judgment. Choice A is an opinion as it categorizes harshness as one of the worst voice qualities, which is subjective. Choice C is also an opinion as it describes how a voice will sound based on subjective terms like 'unpleasant.' Choice D is an opinion as it makes a generalized statement linking higher-pitched voices with shriller voices in women, which can vary widely among individuals.

4. What is the main idea of the passage about Sickle-Cell Anemia?

A. Bone pain is a symptom of sickle-cell anemia.
B. Sickle-cell anemia affects oxygen transport in the body.
C. Sickle-cell anemia is a genetically inherited disease.
D. Sickle-cell anemia is a painful, inherited disease.

Correct answer: D

Rationale: The correct answer is D. The passage focuses on describing sickle-cell anemia as a painful and inherited disease. It details how the abnormal sickle-shaped cells cause symptoms like bone pain, fever, and fatigue. While bone pain is mentioned as a symptom, it is not the main idea of the passage. Choice A is incorrect. Choice B, which mentions oxygen transport, is not the main idea but a general concept. Choice C, stating genetically inherited diseases affect thousands, is too broad and does not focus on the specifics of sickle-cell anemia. Therefore, D is the most precise choice.

5. What is the meaning of the word onset as used in the first paragraph?

A. Cure rate
B. Incubation period
C. Remainder
D. Commencement

Correct answer: D

Rationale: In this context, "onset" refers to the beginning or commencement of dementia symptoms. The term is used to indicate when the disease first becomes noticeable in patients, making option D the correct choice.
