HESI A2 Practice Test Vocabulary

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.

Correct Answer: C

Rationale: The correct answer is C: Easiest. In this sentence, the superlative form "the" is used before the adjective "easiest" to indicate the highest degree of comparison. "Most easiest" (A) is incorrect as "most" is redundant with the superlative form. "Most easy" (B) is incorrect as "easy" should be in the superlative form. "Easy" (D) is incorrect as it is not in the superlative form needed for this context.

Correct Answer: C

Rationale: The correct answer is C: Threatening. The word 'ominous' is used to describe something that suggests harm or danger. In the sentence provided, the word 'ominous' is used to convey that the sign is foreboding or indicating something bad may happen. The other choices are incorrect because: A: A good omen means a sign of good luck, which is the opposite of ominous. B: Without deceit means honest or sincere, which is unrelated to the negative connotation of ominous. D: Full of thought means being contemplative or reflective, which does not align with the negative and threatening meaning of ominous.

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: A

Rationale: The correct answer is A: Confinement away from the general population. Quarantine is a public health practice that separates and restricts the movement of individuals who may have been exposed to a contagious disease to prevent its spread. Choice B, specialist's care, is incorrect as it does not relate to quarantine. Choice C, experimental drug therapy, is incorrect as quarantine is about isolation, not drug treatment. Choice D, imprisonment in a rehabilitation unit, is incorrect as quarantine is a temporary isolation for health reasons, not a form of punishment or long-term confinement.
