Vocabulary HESI A2

Correct Answer: D

Rationale: The correct answer is D: Poison. A toxin is a poisonous substance produced within living cells or organisms. "Impurity" (A) refers to something that is not pure, not necessarily toxic. "Element" (B) refers to a substance that cannot be broken down into simpler substances, not specifically toxic. "Remedy" (C) is a substance used to cure or relieve a disease, not toxic. Therefore, the best synonym for toxin is "Poison" as it specifically denotes a substance that is harmful and can cause illness or death.

Correct Answer: B

Rationale: The correct answer is B: animate him. Vivify means to give life or animation to someone or something. In this context, to vivify someone is to bring energy or liveliness to them. Belittling someone (A) means to make them feel small or unimportant, which is the opposite of vivifying. Alarming someone (C) means causing fear or distress, not bringing life to them. Spoiling someone (D) means to harm or ruin their character, also not related to vivifying. Therefore, the correct answer is B as it aligns with the meaning of vivify.

Correct Answer: A

Rationale: The correct answer is A: Effectiveness. Efficacy refers to the ability of something to produce a desired or intended result. In the context of the sentence, it is referring to how well counterfeit medicines work in achieving their intended purpose. Choice B (Significance), C (Corollary), and D (Conclusion) are incorrect as they do not capture the meaning of efficacy in this context. Significance refers to importance, corollary refers to a consequence, and conclusion refers to a final decision or judgment, none of which are synonymous with efficacy.

Correct Answer: D

Rationale: The correct answer is D: Flexible. Plastic is a synthetic material known for its ability to be easily molded and shaped. It is not related to mechanical properties (A), durability (B), or authenticity (C). Plastic's main characteristic is its flexibility, making it suitable for a wide range of applications. This choice best aligns with the defining feature of plastic material.

Correct Answer: B

Rationale: The correct answer is B: swollen. When a blood vessel is distended, it means it has expanded or become enlarged due to increased pressure or volume of blood. Swollen accurately describes this condition. Choice A, overturned, is unrelated to the expansion of a blood vessel. Choice C, twisted, implies a different type of deformation. Choice D, overlong, does not accurately describe the condition of distended blood vessels.
