HESI A2 Practice Test Vocabulary

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 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: D

Rationale: The correct answer is D because it clearly specifies that the door will remain unlocked only when the business is open, aligning with the original intent. Choice A is incorrect as it mandates the door to be unlocked at all times, which may pose security risks. Choice B is vague and confusing. Choice C is incorrect because the original sentence lacks clarity about when the door should be unlocked.

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.
