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. The eye drops were intended to _____ the pupils for the eye exam.

Correct answer: A

Rationale: The correct answer is 'dilate.' Eye drops are used to dilate the pupils, meaning to widen or enlarge them, which is necessary for an eye exam to allow more light to enter the eye. 'Constrict' (choice B) means to make smaller, which is the opposite effect needed for an eye exam. 'Enlarge' (choice C) is similar in meaning to dilate but is not the correct term used in this context. 'Decrease' (choice D) means to make less or reduce, which is also the opposite of what is required for an eye exam.

3. It is required that he _____ payment immediately.

Correct answer: A

Rationale: The correct answer is 'make.' In this context, 'make' is the correct verb to use with 'payment.' The sentence structure requires a base form of the verb after 'required that.' Choices B, C, and D are incorrect as 'sends,' 'sent,' and 'deliver' do not match the structure needed in this sentence.

4. Another word for SITE is?

Correct answer: B

Rationale: Another word for 'SITE' is 'Location.' In this context, 'site' typically refers to a place or area, making 'Location' the most appropriate synonym among the given choices. Choice A, 'Severity,' does not relate to the meaning of 'site' as a place or area. Choice C, 'Fortunate,' and Choice D, 'Appearance,' are also unrelated to the concept of 'site,' making them incorrect choices.

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

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.
