Reading Comprehension HESI A2 Practice Test

1. 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.

2. Which sound waves have a higher 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: A

Rationale: Sound waves that are closer together have a higher pitch. This is explained by the Doppler Effect, where as a source of sound moves closer to an observer, the waves are compressed, resulting in a higher frequency and a higher pitch. Conversely, when the source moves away, the waves are stretched, leading to a lower frequency and a lower pitch. Therefore, choice A is correct. Choices B, C, and D are incorrect as they do not accurately describe the relationship between sound wave frequency and pitch.

3. The passage implies that?

A. Bridge can be learned with time and effort.
B. Bridge is only for older people
C. Playing bridge requires concentration
D. Bridge is an extremely easy game to play

Correct answer: C

Rationale: The correct answer is C, as the passage indirectly implies that playing bridge requires concentration. This is evident when the passage discusses the custom of giving white elephants in Siam, suggesting that taking care of a white elephant was a burdensome responsibility, requiring focus and concentration. Choice A is incorrect because the passage does not explicitly state that Bridge is easy, but rather mentions that it can be complicated for beginners. Choice B is incorrect as the passage does not mention age as a factor for playing Bridge.

4. Which of the following is not listed as a detail in the passage about microbes?

A. Babies are born coated with germs from the birth canal.
B. Mice and humans respond to microbes differently.
C. Few people share the same microbes in the same quantities.
D. Human bodies contain far more microbes than they do cells.

Correct answer: B

Rationale: The correct answer is B because the passage does not detail that mice and humans respond to microbes differently. The passage discusses how laboratory mice required a particular strain of bacteria to help their immune systems function correctly, indicating a difference in how mice and humans respond to microbes. Choices A, C, and D are all details mentioned in the passage: A discusses babies being coated with germs from the birth canal, C talks about the variation in microbes among individuals, and D states that human bodies contain more microbes than cells.
