HESI A2 Reading Comprehension V1 2024

1. Which sound waves have a lower pitch?

A. Those waves that are closer together
B. Those waves that are farther apart
C. Those waves that travel a long distance
D. Those waves that travel a short distance

Correct answer: B

Rationale: Sound waves that are farther apart have a lower pitch. The Doppler Effect explains that as objects emitting sound move away, the sound waves become more spaced out, resulting in a lower frequency and a lower pitch. Choice A is incorrect because waves that are closer together have a higher frequency and a higher pitch. Choices C and D are not directly related to determining the pitch of sound waves.

2. What is the meaning of the word diligent as used in the last paragraph about Sickle-Cell Anemia?

A. Dispersed.
B. Incensed.
C. Painstaking.
D. Demanding.

Correct answer: C

Rationale: In the context of sickle-cell anemia, diligent means painstaking, indicating the careful and thorough approach required to manage the disease. The passage highlights the challenges of managing the symptoms of sickle-cell anemia and the need for meticulous and conscientious care. Choices A, B, and D are incorrect. 'Dispersed' and 'Incensed' do not align with the meaning of diligent in this context. 'Demanding' does not capture the essence of the careful and thorough care needed to manage the disease.

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

A. Honored
B. Nobility
C. Rich
D. financially weakened

Correct answer: D

Rationale: The word 'impoverished' typically refers to a state of extreme poverty or being financially ruined. In the context of the first paragraph, where it is used to describe the condition of a certain group of people, it indicates that they are lacking in financial resources or are in a state of deprivation. Choice A 'Honored' is incorrect as it has a positive connotation opposite to the negative meaning of 'impoverished.' Choice B 'Nobility' is incorrect as it refers to a high social rank or class, which is unrelated to the financial state implied by 'impoverished.' Choice C 'Rich' is incorrect as it is the opposite of 'impoverished,' denoting wealth and abundance, not financial weakness.
