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 What does it mean if a theory is obsolete?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B. Outdated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Rationale: If a theory is considered obsolete, it means that it is outdated and no longer in current use or practice.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 Choice C, 'Useful,' is incorrect because an obsolete theory is no longer considered useful due to being outdated.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. A remedy may cure certain ailments. Another word for this might be ___________.

A. inoculation
B. indicator
C. nostrum
D. serum

Correct answer: C

Rationale: A "nostrum" is a term used to describe a questionable or untested remedy or medication that claims to cure ailments. In this context, as a remedy is suggested to cure certain ailments, "nostrum" fits best in providing an alternative word that aligns with the situation. The other choices are not synonyms for a remedy that cures ailments. 'Inoculation' refers to the introduction of a vaccine, 'indicator' is something that provides information or signals, and 'serum' is a component of blood or a medication, none of which directly align with the concept of a remedy curing ailments.

3. A condition that is ongoing is ___________.

A. rapid
B. continuous
C. partial
D. complete

Correct answer: B

Rationale: A condition that is ongoing implies that it is happening or existing continuously without interruption. Therefore, the most suitable word to describe such a state is 'continuous.' Choice A, 'rapid,' means fast or quick, which does not convey the idea of ongoingness. Choice C, 'partial,' means incomplete or fragmentary, which is the opposite of ongoing. Choice D, 'complete,' means finished or whole, which also does not align with the concept of ongoing.

4. Which phrase is NOT used correctly in the sentence?

A. Do to
B. Stay was
C. Client's
D. Superinfection

Correct answer: A

Rationale: The correct answer is A. "Do to" should be corrected to "due to" in this context. The sentence should read, "The client's hospital stay was prolonged, due to a superinfection." The phrase "due to" is the appropriate choice to indicate the cause of the prolonged hospital stay. Choices B, C, and D are all used correctly in the sentence and do not contain any errors.

5. What does Milieu mean?

A. A person's background
B. The environmental condition or setting
C. A person's history
D. The chemical composition

Correct answer: B

Rationale: The correct answer is B: 'The environmental condition or setting.' Milieu refers to the surroundings or environment in which a person lives or operates. Choice A ('A person's background') is incorrect as it refers more to someone's personal history rather than the external environment. Choice C ('A person's history') is also incorrect as it specifically relates to an individual's past events and experiences. Choice D ('The chemical composition') is unrelated to the meaning of milieu, which pertains to the physical or social setting.
