Vocabulary HESI A2 Practice Test

1. What does it mean if a theory is obsolete?

A. Advanced
B. Outdated
C. Useful
D. Innovative

Correct answer: B

Rationale: If a theory is considered obsolete, it means that it is outdated and no longer in current use or practice. Choice A, 'Advanced,' is incorrect as it implies progression rather than obsolescence. Choice C, 'Useful,' is incorrect because an obsolete theory is no longer considered useful due to being outdated. Choice D, 'Innovative,' is incorrect as it suggests newness and originality, which are opposite to being obsolete.

2. If tubes distend, they ___________.

A. flex
B. stretch
C. solidify
D. collapse

Correct answer: B

Rationale: When tubes distend, they expand or become enlarged, which typically results in stretching rather than flexing, solidifying, or collapsing. Distending tubes imply an increase in size or volume, indicating a stretching or expansion effect. Therefore, the correct answer is 'stretch.' Choice A, 'flex,' is incorrect as flexing refers to bending or curling, not expanding. Choice C, 'solidify,' is incorrect as solidifying refers to becoming solid, which is not related to the expansion of tubes. Choice D, 'collapse,' is incorrect as collapsing refers to falling in or giving way, which is the opposite effect of distending.

3. Someone who is FRUSTRATED/ANNOYED is?

A. Exacerbated
B. Transient
C. Lithe
D. Terse

Correct answer: A

Rationale: The word 'exacerbated' means to make a problem, bad situation, or negative feeling worse. If someone is frustrated or annoyed, they are likely feeling worse due to a particular situation or circumstance. Choice B, 'transient,' means temporary or short-lived, which does not directly relate to the feeling of being frustrated or annoyed. Choice C, 'lithe,' means thin, supple, and graceful, which is not synonymous with being frustrated or annoyed. Choice D, 'terse,' means brief and to the point, which is unrelated to the context of feeling frustrated or annoyed.

4. Choose the meaning of the word 'sanctioned' in the following sentence: 'The professor sanctioned our field trip to the chemistry lab.'

A. Organized
B. Deterred
C. Neglected
D. Authorized

Correct answer: D

Rationale: In this context, the word 'sanctioned' means to authorize or approve. The sentence indicates that the professor gave permission for the field trip to the chemistry lab, which aligns with the meaning of 'authorized.' Choices A, B, and C are incorrect. 'Organized' does not fit the context as the sentence is about granting approval, not arranging. 'Deterred' means to discourage, which is the opposite of what the professor did. 'Neglected' means failed to care for or pay attention to, which is unrelated to the professor approving the field trip.

5. The voice box may be called the ______

A. Pharynx
B. Larynx
C. Trachea
D. Esophagus

Correct answer: B

Rationale: The correct term for the voice box is the larynx. The pharynx is part of the throat involved in swallowing and breathing but not the voice production. The trachea is the windpipe responsible for air passage, and the esophagus is the tube that carries food from the mouth to the stomach. Therefore, in this context, the larynx is the most appropriate term.
