HESI A2 Vocabulary 2023

Correct Answer: A

Rationale: The correct answer is A: Bogus. 'Spurious' means not genuine or false, which aligns with 'bogus.' The sentence suggests the researcher made a misleading or false argument. Choice B, obscure, means unclear or hard to understand, which doesn't fit the context. Choice C, baffling, means confusing or perplexing, but doesn't capture the deceitful nature of 'spurious.' Choice D, outrageous, means shocking or offensive, which is not the same as being false or deceptive. Therefore, 'bogus' is the best fit for the context of the sentence.

Correct Answer: A

Rationale: The correct answer is A: Makes a suggestion about. In the sentence, 'suggests that' indicates that the study is proposing or indicating a possibility that vaping may have certain effects. It implies a tentative conclusion rather than providing concrete evidence (B), subtly alluding to an idea without explicitly stating it (C), or advocating for a specific course of action (D). Therefore, 'suggests that' aligns best with the idea of presenting a suggestion or implication, making choice A the most fitting description.

Correct Answer: D

Rationale: The correct answer is D, "To move side to side." In the context of the sentence, 'yaw' refers to a horizontal movement of the robotic arm requiring adjustment. This movement aligns with the definition of yaw as a side-to-side motion, commonly used in aviation and robotics. Choice A, "To gape open," is incorrect as it does not fit the context of the sentence. Choice B, "To move up and down," does not align with the horizontal movement described. Choice C, "To close tightly," is also incorrect as it does not relate to any form of movement but rather a stationary action.

Correct Answer: A

Rationale: The correct answer is A: short-lived. Transitory means temporary or not lasting long. Short-lived is synonymous with transitory. Other choices (B, C, D) do not accurately describe transitory symptoms. Damaging (B) implies causing harm, fluctuating (C) means constantly changing, and degenerating (D) suggests worsening over time, none of which align with the definition of transitory.

Correct Answer: D

Rationale: The correct answer is D: Quivering and weak. In the sentence, 'tremulous hand' implies a shaky and unsteady hand, indicating a state of nervousness or fear. This aligns with the definition of 'tremulous' meaning quivering and weak. Choice A is incorrect as it describes a different physical characteristic. Choice B is incorrect as it focuses on color and vitality rather than the intended meaning of the word. Choice C is incorrect as it describes a different type of hand movement unrelated to the context of the sentence.
