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: D

This behavior is often displayed through arguments and confrontations with others. It is important to differentiate between truculent and the other choices.

This choice best aligns with the defining feature of plastic material.

Correct Answer: D

Rationale: The correct answer is D: A review or inspection.

Choice B is incorrect as audits are not a payment for inventory but a process to ensure the accuracy of financial reporting. Choice C is incorrect as audits are not a test of hearing but a systematic examination of records and processes.
