HESI A2 Practice Test Vocabulary

Correct Answer: C

Rationale: The correct answer is C because the word "environment" refers to the surroundings or conditions in which a person, animal, or plant lives or operates. It encompasses both external factors (like physical surroundings, social interactions, etc.) and internal factors (like mental, emotional, and physical well-being). Choices A, B, and D are incorrect as they do not accurately capture the comprehensive nature of the term "environment." A refers more to societal concepts, B is too narrow in focus, and D is limited to a specific aspect of a home environment. Therefore, C is the most appropriate choice as it encapsulates the full scope of the term "environment."

Correct Answer: C

Rationale: Rationale: 1. 'Impervious' means not affected or unaffected by something. 2. In the given sentence, it implies that the subject is not impacted by something. 3. Choices A, B, and D do not align with the meaning of 'impervious.' 4. Choice A suggests coping well, which is different from being unaffected. 5. Choice B implies enjoyment, unrelated to being unaffected. 6. Choice D suggests being very sensitive, opposite to being impervious.

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.

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: C

Rationale: The correct answer is C: Flexible. The plumber used a flexible tube because it can bend and conform to the shape of the curved pipe, making it easier to navigate through the twists and turns. A solid or rigid tube would not be able to maneuver through the curved pipe effectively. Perforated tube has holes and would not be suitable for clearing blockages. In summary, the flexibility of the tube allows it to adapt to the shape of the pipe, making it the most appropriate choice for this task.
