HESI A2 Vocabulary Practice Test

1. What is the word part placed before a word to change its meaning?

A. Prefix
B. Affix
C. Suffix
D. Vocab

Correct answer: A

Rationale: A prefix is the correct answer. A prefix is a word part attached at the beginning of a word to modify its root word, changing the definition or grammatical function of the word. Examples of prefixes include "un-" in "unhappy," "re-" in "redo," and "pre-" in "preview." Choice B, "Affix," is incorrect because while a prefix is a type of affix, not all affixes are prefixes. Choice C, "Suffix," is incorrect as a suffix is a word part added at the end of a word to change its meaning. Choice D, "Vocab," is incorrect as it refers to vocabulary or words related to a particular subject rather than a word part placed before a word.

2. If illegal operators are posing as licensed pharmacists, what are they doing?

A. Modeling
B. Inquiring
C. Positioning
D. Pretending

Correct answer: D

Rationale: If illegal operators are posing as licensed pharmacists, they are pretending to be licensed pharmacists when they are not. This deceptive behavior is misleading and potentially dangerous for consumers seeking legitimate medical advice and products. Choice A, modeling, implies imitating behavior or appearance, which is not the case here. Choice B, inquiring, suggests seeking information or asking questions, which is not the correct behavior in this context. Choice C, positioning, refers to arranging or placing things in a particular way, which is not relevant to the situation described in the question.

3. What is another word for AEGIS?

A. Relationship
B. Respectability
C. Ramifications
D. Responsibility

Correct answer: B

Rationale: AEGIS is synonymous with protection, sponsorship, or support. Respectability aligns with this notion as it relates to being socially acceptable or esteemed, which can be seen as a form of protection or favorable regard. 'Relationship' (Choice A) does not capture the protective or supportive aspect of AEGIS. 'Ramifications' (Choice C) and 'Responsibility' (Choice D) are not synonyms for AEGIS. They do not convey the sense of protection or support associated with it.

4. What does 'Impaired' mean?

A. Increased capability
B. Diminished or lacking usual quality
C. Hyperactive
D. Stronger than usual

Correct answer: B

Rationale: The term 'Impaired' means diminished or lacking usual quality. This choice is correct as it accurately reflects the meaning of the word. Choices A, C, and D are incorrect. Choice A, 'Increased capability,' is the opposite of impaired. Choice C, 'Hyperactive,' refers to excessive activity rather than a lack of usual quality. Choice D, 'Stronger than usual,' does not capture the meaning of impaired.

5. Which sentence is grammatically correct?

A. Somebody left their jacket on the train
B. Somebody left his or her jacket on the train
C. His jacket was left on the train
D. His or her jacket was left on the train

Correct answer: B

Rationale: The sentence 'Somebody left his or her jacket on the train.' is grammatically correct and respects gender neutrality. 'Somebody' is singular, so the pronoun 'their' in choice A is incorrect. Choice C changes the subject from 'somebody' to 'his,' making it grammatically incorrect. Choice D is grammatically correct, but it is less concise and more awkward than choice B, which smoothly combines 'his' and 'her' for gender-neutral language.
