Vocabulary HESI A2 Practice Test

Correct Answer: B

Rationale: The correct answer is B: Disregard. The word "contravene" means to violate or disobey. In this context, the interns did not follow the doctor's orders, which implies they disregarded them. Choice A (Follow) is incorrect because the interns did not adhere to the orders. Choice C (Exceed) is incorrect as it suggests going beyond the orders, not disobeying them. Choice D (Respect) is incorrect as it implies the interns obeyed the orders, which is not the case. Therefore, the best fit is B as the interns went against the doctor's instructions.

Correct Answer: A

Rationale: The correct answer is A: "This door will remain unlocked when the office is occupied." The use of "will" indicates a future action, ensuring the door remains unlocked during office occupancy. Choice B is similar but lacks the future tense, making it less definitive. Choice C uses the present tense, which does not convey the intended future action. Choice D uses "while," implying the door is only unlocked temporarily during office occupancy, which may not be the desired instruction.

Correct Answer: B

Rationale: The correct answer is B: Changing rapidly and often. Labile means easily altered, unstable, or constantly changing. This term is commonly used in psychology and medicine to describe emotions or conditions that fluctuate frequently. Choice A (Stable) is incorrect because labile implies the opposite of stability. Choice C (Unchanging) and choice D (Rarely changing) are also incorrect as they do not align with the definition of labile, which specifically denotes frequent changes.

Correct Answer: B

Rationale: The correct answer is B: A tool or piece of equipment. A device is defined as a tool or piece of equipment designed for a specific purpose, such as a smartphone or a computer. This choice aligns with the general definition of a device and is the most accurate description among the options provided. A: An idea or concept is incorrect because a device is a physical object, not an abstract idea. C: A small part of a larger structure is incorrect because while a device can be a component of a larger system, it is not limited to being just a small part. D: An accessory for fashion is incorrect as a device is primarily functional and serves a specific purpose, not purely for fashion or aesthetics.

Correct Answer: B

Rationale: The correct answer is B: Activate. Instigate means to initiate or start something, typically something negative or challenging. In this context, it refers to initiating an action or process. Deactivate (A) means to make something inactive, which is the opposite of instigate. Suppress (C) means to prevent or restrain, not initiate. Evaluate (D) means to assess or judge, not start or activate. Therefore, B is the correct answer as it aligns with the meaning of instigate in initiating or activating a process.
