HESI A2 Practice Test Vocabulary

Correct Answer: B

Rationale: The correct answer is B: Convulsion. A paroxysm is defined as a sudden spasm or seizure, which is synonymous with convulsion. Symptom (A) refers to an indication of a condition, not the same as a spasm. Efficacy (C) means the ability to produce a desired or intended result, unrelated to sudden spasms. Embolism (D) is a blockage of a blood vessel, not related to spasms. Therefore, the correct choice is B as it directly relates to the sudden spasm characteristic of a paroxysm.

Correct Answer: D

Rationale: The correct answer is D: Justification. Justification implies providing a valid reason or explanation for one's actions. In this context, the sentence suggests that the person had no valid reason for treating her boyfriend poorly. A: Alibi implies an excuse to avoid blame, not relevant here. B: Rational refers to logical thinking, not about the legitimacy of her actions. C: Reasonable means fair or sensible, but it doesn't address the necessity of providing a valid reason for behavior.

Correct Answer: A

Rationale: The correct answer is A: Confirmed the truth of. The word "assured" means to make certain or confident about something. Therefore, "confirmed the truth of" is the most suitable synonym as it implies establishing certainty. The other choices are incorrect because: B: Sympathized with means to show compassion, C: Denied the truth of means to reject or oppose the truth, and D: Made known to means to reveal or inform, none of which capture the essence of being assured.

Correct Answer: C

Rationale: The correct answer is C: Gradual. In the sentence, 'insidious' describes a disease that progresses slowly and unnoticed before showing symptoms. The word 'insidious' typically implies a gradual and subtle development, unlike sudden or immediate changes. Choice A, sudden, is incorrect as 'insidious' conveys a sense of hidden or subtle rather than sudden. Choice B, suffer, is incorrect as 'insidious' does not directly relate to suffering. Choice D, graduate, is incorrect as it does not align with the context of the sentence or the meaning of 'insidious.'

Correct Answer: A

Rationale: The correct answer is A: Imply. When someone implies something, they suggest or hint at it indirectly. "Imply" is the verb form of the action. Choice B, Infer, means to deduce or conclude based on evidence or reasoning, so it is the recipient of the implication. Choices C and D, Opinion and Latter, do not relate to the action of suggesting or hinting indirectly. Therefore, A is the correct choice as it directly aligns with the definition provided in the question.
