HESI A2 Vocabulary Practice Test

Correct Answer: A

Rationale: The correct answer is A: Prefix. A prefix is a word part placed before a word to change its meaning. It modifies the root word's meaning. For example, adding "un-" before "happy" changes the meaning to "unhappy." Affix (B) is a broader term that includes both prefixes and suffixes. Suffix (C) is a word part placed after a word, and Vocab (D) stands for vocabulary, which is not directly related to changing the meaning of a word.

Correct Answer: B

Rationale: The correct answer is B: Entering into a body part. Invasive refers to something that intrudes or penetrates into another entity. In medical terminology, it specifically refers to procedures or organisms entering the body. Choice A is incorrect because invasive doesn't imply harmlessness. Choice C is incorrect as invasive is more than just mildly irritating. Choice D is incorrect because invasive does involve penetration.

Correct Answer: B

Rationale: The correct answer is B: To draw together. In the context of contracts, 'contract' refers to an agreement between two or more parties where they come together and bind themselves to certain terms. Choice A, 'to expand,' is incorrect because a contract involves parties coming together, not expanding. Choice C, 'to elongate,' is incorrect because it refers to stretching or lengthening, which is not related to forming a contract. Choice D, 'to dissolve,' is incorrect because it means to end or terminate, the opposite of what a contract does, which is to establish an agreement.

Correct Answer: B

Rationale: The correct answer is B: Able to be heard. Audible refers to something that can be heard. This is because the term "audible" is derived from the Latin word "audire," which means "to hear." Therefore, when something is audible, it means it can be perceived by the sense of hearing. Incorrect choices: A: Impossible to hear - This is incorrect as audible means the opposite, something that can be heard. C: Visible - This is incorrect as audible pertains to sound, not sight. D: Silent - This is incorrect as audible refers to something that can be heard, not something that is silent.

Correct Answer: A

Rationale: The correct answer is A: Buttress. Buttressing involves providing structural support to prevent collapse. In the context of a falling fence, buttressing would involve reinforcing the weak section to prevent it from falling apart further. Degrade (B), hinder (C), and flounder (D) are all incorrect as they do not address the specific action needed to address the falling fence. Degrade means to deteriorate, hinder means to obstruct, and flounder means to struggle or fail.
