HESI A2 Practice Test Vocabulary

Correct Answer: A

Rationale: The correct answer is A: Chronology. Chronology refers to the arrangement of events in the order of their occurrence. This term is specifically used to describe the chronological sequence of events. Notation (B) refers to symbols or marks used to represent something, not the order of events. Documentation (C) refers to the process of recording or providing evidence, not necessarily in chronological order. Helicon (D) is a term not related to the order of events. Therefore, A is the correct answer as it directly relates to the description of events in the order of their occurrence.

Correct Answer: A

Rationale: The correct sentence using 'etc.' is A: "The list included diseases such as flu, measles, etc." This sentence is correct because 'such as' is used before 'flu' and 'measles,' indicating that they are examples, and 'etc.' is used appropriately to show there are other diseases not listed. In contrast, option B incorrectly uses 'etc.' after 'flu' and 'measles' without a preceding 'such as.' Option C places 'etc.' after 'measles' and 'diseases,' making the sentence awkward and redundant. Option D incorrectly places 'etc.' after 'flu' and before 'measles,' disrupting the flow of the sentence.

Correct Answer: C

Rationale: The correct answer is C: Hold fast. Adhere means to stick firmly to something. In this context, "hold fast" best captures the idea of maintaining a strong attachment or connection. Choice A, remain intact, does not convey the idea of sticking or clinging. Choice B, loosen, is the opposite of adhere. Choice D, position next to, does not capture the concept of sticking or adhering to something. Therefore, choice C is the most appropriate synonym for adhere in this context.

Correct Answer: B

Rationale: The correct answer is B: Destructive. 'Pernicious' means causing harm in a subtle or gradual way. It is commonly used to describe something that has a destructive or harmful effect. The word 'valued' (A) means cherished or esteemed, not harmful. 'Finicky' (C) means overly picky or fussy, not harmful. 'Perpetual' (D) means constant or never-ending, not necessarily harmful. Therefore, the most appropriate choice is B as it aligns with the definition and common usage of 'pernicious.'

Correct Answer: C

Rationale: The correct answer is C: Because. The word "because" indicates the reason for an action. In this case, Sheila brought her umbrella to work as a result of the meteorologist forecasting rain. The word "because" establishes the cause-and-effect relationship between the forecast and Sheila's action. Incorrect choices: A: Nor - Nor is used to present a negative condition or to indicate a lack of something. It does not fit in this context. B: Yet - Yet is used to contrast two ideas. It does not convey the causal relationship between the forecast and Sheila's action. D: So - So is used to indicate a consequence or a result. While it could work in some contexts, it doesn't clearly explain the reason for Sheila bringing her umbrella.
