Vocabulary for HESI A2

Correct Answer: B

Rationale: The correct answer is B: Destructive. Pernicious means causing harm in a subtle or gradual way. It is not harmless (choice A) or helpful (choice C). While harmful (choice D) is a similar concept to pernicious, the key difference lies in the subtle or gradual nature of pernicious, which is not captured by simply being harmful. Therefore, choice B is the best meaning for pernicious.

Correct Answer: B

Rationale: The correct answer is B: Argumentative. Truculent means aggressive or quick to argue, making argumentative the most fitting choice. Friendly (A) is the opposite of truculent. Cooperative (C) implies willingness to work together, which doesn't align with truculent behavior. Passive (D) is the opposite of truculent as it signifies a lack of resistance or assertiveness.

Correct Answer: B

Rationale: The correct answer is B: Cure. A panacea is a remedy or solution for all problems or diseases, making it synonymous with the word "cure." This term implies a universal or ultimate solution. Choices A, C, and D are not synonymous with panacea. Poison (A) is the opposite of a panacea, as it causes harm instead of providing healing. Treatment (C) is a specific action taken to address a particular issue, not a universal solution. Remedy (D) is similar to panacea, but it typically refers to a solution for a specific problem, whereas panacea implies a cure for all problems.

Correct Answer: C

Rationale: The correct answer is C: Experimental. The word "experimental" implies trying new methods or approaches before resorting to a standard procedure. In this context, the doctor wants to explore different options before considering a risky or invasive procedure. A: Internal - This choice does not fit the context of trying alternative methods before a procedure. It refers to something inside the body, not the nature of the procedure itself. B: Painful - This choice focuses on the potential discomfort of the procedure, which is not the main point of the sentence. The doctor is emphasizing trying other approaches first. D: Expensive - This choice does not relate to the idea of trying different methods before a procedure. The cost of the procedure is not the primary concern in this sentence.

Correct Answer: B

Rationale: The correct answer is B: Surplus. Redundancy refers to having more than is needed, which aligns with the concept of surplus. Choice A, deficiency, is the opposite of redundancy. Choice C, delicate, is unrelated to the definition of redundancy. Choice D, abundance, is somewhat related but not as precise as surplus in the context of redundancy. In summary, the correct answer is B because redundancy specifically refers to having an excess or surplus of something.
