HESI A2

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 What does it mean if a theory is obsolete?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B. Outdated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Rationale: If a theory is considered obsolete, it means that it is outdated and no longer in current use or practice.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 Choice C, 'Useful,' is incorrect because an obsolete theory is no longer considered useful due to being outdated.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. Which word in the sentence needs to be corrected for proper grammar?

A. About it
B. A
C. With
D. Made

Correct answer: B

Rationale: The word 'A' should be corrected to 'an' in the sentence. The sentence should read, 'The nurse made an error with the medication, so the doctor made notes about it in the patient's file.' The article 'an' is used before a noun beginning with a vowel sound, like 'error' in this case. Choices A, C, and D are grammatically correct in the sentence and do not need to be altered.

3. Choose the meaning of the word vent in the following sentence: 'A tube is used to vent the gases to the outside.'

A. Block
B. Trade
C. Emit
D. Inhale

Correct answer: C

Rationale: In this sentence, the word 'vent' means to allow the gases to escape or be emitted to the outside. 'Block' is incorrect because it means to obstruct or close off. 'Trade' is incorrect as it refers to the exchange of goods or services. 'Inhale' is incorrect as it means to breathe in, which is the opposite of venting gases out.

4. What is another word for panacea?

A. Poison
B. Cure
C. Treatment
D. Remedy

Correct answer: B

Rationale: The correct answer is B: Cure. A panacea is a remedy or cure for all diseases. While 'poison' (choice A) is the opposite of a cure, 'treatment' (choice C) is a general approach to addressing an illness rather than a universal solution, and 'remedy' (choice D) is synonymous with cure but not as closely related to the concept of a universal remedy as 'cure'.

5. What is another word for compendium?

A. Collection
B. Aptitude
C. Conclusion
D. Humor

Correct answer: A

Rationale: A compendium is a collection of concise but comprehensive information on a particular subject. Therefore, another word for compendium is "collection." The term "aptitude" refers to a natural ability to do something, not synonymous with compendium. "Conclusion" is a decision or judgment reached after considering the facts, not related to a compendium. "Humor" refers to the quality of being amusing or comic, not a synonym for compendium.
