HESI A2 Vocabulary Quiz

1. What is a diagnostic test?

Correct answer: B

Rationale: A diagnostic test is a medical test or procedure performed to identify the cause of a health problem, disease, or condition. It helps healthcare providers make accurate diagnoses and determine appropriate treatments for patients. Choice A is incorrect because a diagnostic test does not locate a cure but rather aims to identify the cause of a health issue. Choice C is incorrect as a diagnostic test is not specifically for examining the skin but can involve various types of tests on different parts of the body. Choice D is incorrect as a diagnostic test is not performed on doctors but on patients to diagnose their health conditions.

2. What is the best description of the verb emit?

Correct answer: A

Rationale: The best description of the verb emit is 'to discharge.' Emit means to produce and release something such as a sound, odor, or substance. Discharge is synonymous with emit in this context as it conveys the idea of releasing or sending out something, which aligns with the meaning of emit. Choices B, C, and D are incorrect. 'To exclude' means to deny access or prevent from entering, which is not the same as emit. 'To dismiss' means to remove from consideration or to let go, which is different from emitting. 'To moderate' means to make or become less extreme, intense, or severe, which is not the same as emitting or releasing something.

3. What does Ominous mean?

Correct answer: B

Rationale: Ominous means giving the impression that something bad or unpleasant is going to happen; threatening; inauspicious. This choice is correct as it accurately reflects the meaning of the term 'Ominous.' Choices A, C, and D are incorrect because they all suggest a lack of importance, danger, or threat, which is opposite to the actual meaning of 'Ominous.'

4. What does 'Obsolete' mean?

Correct answer: B

Rationale: The correct answer is 'B: Outdated.' Obsolete refers to something that is outdated or no longer in use. 'Innovative' (choice A) means introducing new ideas or methods; 'Effective' (choice C) means successful in producing a desired result; 'Advanced' (choice D) means far on or ahead in development or progress. Therefore, 'Outdated' is the most appropriate antonym for 'Obsolete.'

5. What does the quoted word 'cornucopia' mean in the following sentence?

Correct answer: A

Rationale: The correct answer is A: 'Plethora.' In the context provided, 'cornucopia' is used metaphorically to signify an abundance or a large variety of stimulating questions and conversation. 'Plethora' is a synonym for 'cornucopia' and means an excessive amount or abundance. Choices B, C, and D are incorrect. 'Ostracism' means exclusion or rejection, 'Laborious' means requiring a lot of effort, and 'Pensive' means engaged in deep thought.
