Vocabulary HESI A2 Practice Test

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: Present on two sides. "Bilateral" refers to something that exists or occurs on two sides. For example, bilateral symmetry means that an object can be divided into two equal halves. Choice A is incorrect because "unilateral" means occurring on one side. Choice C is incorrect as it describes something random, not specifically on two sides. Choice D is incorrect because "bilateral" implies a presence on two sides, not the absence of occurrence.

Correct Answer: B

Rationale: The correct answer is B: Complaining. Querulous means constantly complaining or expressing dissatisfaction. This is because the word is derived from the Latin word "queri" which means to complain. Shouting (A), crying (C), and praising (D) do not align with the definition of querulous. Shouting is about making a loud noise, crying is about expressing sadness or distress, and praising is about expressing approval or admiration. Therefore, B is the most appropriate choice that accurately reflects the meaning of querulous.

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.

Correct Answer: B

Rationale: The correct answer is B: Outdated. When a theory is considered obsolete, it means it is no longer relevant or valid due to new information or advancements in the field. This indicates that the theory is no longer up-to-date and has been surpassed by newer, more accurate theories. Choices A, C, and D are incorrect because an obsolete theory is not advanced, useful, or innovative; rather, it is outdated and no longer applicable in current context.
