HESI A2 Vocabulary 2023

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.

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: Step 1: Understand the definition - Bifurcate means to divide or split into two branches or forks. Step 2: Analyze the choices - A is incorrect as bifurcate does not involve folding. B is incorrect as it refers to flowering, not dividing. D is incorrect as it involves piercing, not dividing. Step 3: Choose the correct answer - C accurately describes the act of dividing into two forks, aligning with the definition of bifurcate. Summary: Choice C is correct as it directly relates to the definition of bifurcate, while the other choices are incorrect as they do not capture the essence of the word.

Correct Answer: B

Rationale: The correct answer is B: Drooping or loose. Flaccid means lacking firmness or stiffness, often used to describe something that is limp or lacking in strength or vigor. In this context, flaccid refers to something that is drooping or loose. Choice A is incorrect as light-colored does not relate to the definition of flaccid. Choice C is incorrect as uncontaminated is not a synonym of flaccid. Choice D is incorrect as unusually aggressive is unrelated to the meaning of flaccid.

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.
