HESI A2 Practice Test Vocabulary

Correct Answer: D

Rationale: The correct answer is D: Basic. In the context of the sentence, 'fundamental' means basic, essential, or foundational. The term 'fundamental' refers to something that is crucial, primary, or indispensable. It is not synonymous with the other choices. A: Appropriate does not capture the essence of 'fundamental.' B: Underlying is related but doesn't fully convey the sense of essentialness. C: Dosage is completely unrelated to the meaning of 'fundamental' in this context. So, the correct choice is D as it best aligns with the meaning of 'fundamental' in the sentence.

Correct Answer: B

Rationale: The correct answer is B: Reason. 'Rational' is related to reason, logic, and sound judgment. It implies making decisions based on logical thinking rather than emotions. Angry (A) does not relate to 'rational.' Rodent (C) and Proportion (D) are also unrelated to the meaning of 'rational.'

Correct Answer: B

Rationale: The correct answer is B: Immigrating. When people move to a new country, they are immigrating. In this context, the sentence refers to people coming into the United States, causing a shift in unemployment. "Emigrating" (A) means leaving one's own country, which is the opposite of the intended meaning. "Migrating" (C) is a general term for moving from one place to another and does not specifically refer to crossing international borders. "Emigrated" (D) is the past tense form and does not fit grammatically in the sentence. Therefore, the most suitable choice is B as it accurately conveys the idea of people moving into the United States.

Correct Answer: C

Rationale: The correct answer is C: "They're, their." Step 1: "They're" is a contraction for "they are," indicating the subject of the sentence having trouble. Step 2: "Their" is a possessive pronoun showing ownership of the new dog. Therefore, the correct usage is "They're having trouble with their new dog." Other choices are incorrect because: A: "There, their" - "There" is an adverb indicating a place, not suitable in this context. B: "Their, there" - Incorrect word order, as "their" should come before the verb. D: "Their, they're" - Incorrect usage of "they're" as a possessive pronoun.

Correct Answer: A

Rationale: The correct answer is A: Plethora. 'Cornucopia' refers to an abundance or a large quantity of something. It is often symbolized by the horn of plenty overflowing with fruits and flowers. A is the best fit as it directly relates to the concept of abundance. B: Ostracism means exclusion or rejection, not abundance. C: Laborious means requiring a lot of effort or hard work, opposite in meaning to abundance. D: Pensive means deeply thoughtful or reflective, not related to abundance.
