HESI A2 Practice Test Vocabulary

Correct Answer: C

Rationale: The correct answer is C: Contour. Plastic surgery often focuses on enhancing the shape and structure of facial features, which is captured by the term "contour." "Bearing" refers to one's posture or demeanor, not facial appearance. "Serenity" pertains to a state of calmness, unrelated to physical changes. "Cataract" is a medical condition affecting the eyes, not relevant to plastic surgery outcomes. Therefore, "Contour" is the most appropriate choice in the context of improving facial aesthetics through plastic surgery.

Correct Answer: A

Rationale: The correct answer is A: Predict. Anticipate means to expect or foresee something happening before it occurs, which aligns with the definition of predict. Evaluating involves assessing or judging, not necessarily foreseeing. Comparing focuses on finding similarities or differences. Forestalling means preventing or hindering something, not predicting it. Therefore, A is the most appropriate synonym for anticipate.

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: 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: Gradual. In the context of disease development, "insidious" means slow and subtle in onset. This term implies a gradual progression without immediate noticeable symptoms. Choice B, momentous, means significant or important, which is not related to the gradual nature of the disease. Choice C, sudden, is the opposite of insidious, indicating a rapid onset. Choice D, innocuous, means harmless, which is not relevant to the negative connotation of insidious in disease development.
