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: D

Rationale: The correct answer is D: Authorized. In this context, "sanctioned" means the professor gave official permission or approval for the field trip. This is evident from the sentence structure where the professor is allowing or permitting the trip. Choices A, B, and C are incorrect because they do not align with the meaning of the sentence. "Organized" (A) implies planning, "Deterred" (B) means discouraged, and "Neglected" (C) means ignored, none of which fit the context of the sentence.

Correct Answer: C

Rationale: The correct answer is C: Greedy. Venal means capable of being bought or influenced by money, hence synonymous with greed. Choice A, Vibrant, is unrelated. Choice B, Savage, does not align with the definition of venal. Choice D, Fortunate, is also not related to the meaning of venal. In summary, the correct answer is C because it directly reflects the definition of venal, while the other choices are not relevant in this context.

Correct Answer: A

Rationale: The correct answer is A: A test of brain activity. EEG stands for Electroencephalogram, which is a test that measures electrical activity in the brain. This test is commonly used to diagnose epilepsy, sleep disorders, and other neurological conditions. Choice B is incorrect as EEG is not a service but a diagnostic test. Choice C is incorrect as EEG does not monitor heartbeats. Choice D is incorrect as EEG has no relation to dentistry. EEG specifically focuses on brain activity, making choice A the most appropriate description.

Correct Answer: C

Rationale: The correct answer is C: Managed and run. In the context of the sentence, "operated" refers to the management and running of the hospitals by administrative medical groups. This choice best fits the context of the sentence as it accurately describes the action being taken by these groups. Explanation: - A (Performing surgery): This choice is incorrect as the word "operated" in the sentence does not refer to performing surgery but rather to the overall management and running of the hospitals. - B (In effect): This choice is incorrect as it does not fully capture the meaning of "operated" in the context of the sentence, which implies active management and operation of the hospitals. - D (Brought about): This choice is incorrect as it does not accurately describe the ongoing management and running of the hospitals by the administrative medical groups.
