HESI A2 Vocabulary 2023

Correct Answer: B

Rationale: The correct answer is B: quite stubborn. "Obdurate" means stubborn or refusing to change one's opinion or course of action. Therefore, a patient who is especially obdurate would be characterized as being quite stubborn. The other choices are incorrect because being obdurate does not necessarily have any direct correlation with being very large (A), easily upset (C), or ready to go home (D). It specifically refers to being stubborn or resistant to change, making choice B the most fitting description.

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: shrill. Strident means loud and harsh, often referring to a high-pitched sound. Shrill is synonymous with strident, making it the most appropriate choice. Muted (B) means softened or subdued, opposite of strident. Constant (C) means unchanging, not related to the loudness or harshness of the sound. Resonant (D) means deep and full, again not fitting the definition of strident. Therefore, A is the correct choice.

Correct Answer: A

Rationale: The correct answer is A: Ripple. In this sentence, 'undulate' is used to describe a smooth, wave-like motion of the muscles, which aligns with the meaning of 'ripple.' The word 'undulate' implies a continuous and flowing movement, resembling the gentle and rhythmic movement of waves. The other choices, shake, flatten, and unknot, do not capture the specific fluid and continuous motion described in the sentence. 'Shake' implies a more abrupt and irregular movement, 'flatten' suggests a completely different action of making something flat, and 'unknot' refers to the action of undoing a knot, none of which fit the context of the sentence.

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.
