HESI A2 Practice Test Vocabulary

Correct Answer: B

Rationale: The correct answer is B: Residual. In the context of the sentence, 'residual' refers to something that remains or is left over. The word 'resident' (A) refers to a person who lives in a particular place, 'resistance' (C) refers to the act of opposing or withstanding something, and 'resin' (D) is a sticky substance. Therefore, B is the correct choice as it directly relates to the meaning of something that remains.

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: D

Rationale: The correct answer is D: Discharge. Flux refers to the process of flowing or continuous change. Discharge aligns with this definition as it signifies the release or movement of something, reflecting the idea of flow or change. Quantity (A) refers to amount, Inflation (B) refers to a rise in prices, and Strength (C) refers to power or energy, none of which directly relate to the concept of flux.

Correct Answer: C

Rationale: The correct answer is C because the word "environment" refers to the surroundings or conditions in which a person, animal, or plant lives or operates. It encompasses both external factors (like physical surroundings, social interactions, etc.) and internal factors (like mental, emotional, and physical well-being). Choices A, B, and D are incorrect as they do not accurately capture the comprehensive nature of the term "environment." A refers more to societal concepts, B is too narrow in focus, and D is limited to a specific aspect of a home environment. Therefore, C is the most appropriate choice as it encapsulates the full scope of the term "environment."

Correct Answer: A

Rationale: The correct answer is A: Prefix. A prefix is a word part placed before a base word to change its meaning. It comes before the root word and alters its definition. Prefixes are essential in forming new words and expanding vocabulary. Choice B: Affix is a broad term that refers to both prefixes and suffixes. While technically correct, it is not as specific as prefix in this context. Choice C: Suffix is a word part placed after a base word to change its meaning. It is the opposite of a prefix. Choice D: Vocab is short for vocabulary and does not relate to the word part placed before a word to change its meaning.
