HESI A2 Vocabulary 2024

Correct Answer: D

Rationale: The correct answer is D because the question states that the lump is palpable, meaning it can be felt. This indicates that the lump is physically detectable by touch, which is a characteristic of a palpable lump. Choices A, B, and C are incorrect because the question does not provide any information to suggest that the lump is malignant, has burst, or is warm. Therefore, the correct answer is D based on the specific information given in the question.

Correct Answer: B

Rationale: The correct answer is B: unaffected by. In medicine, resistance refers to the ability of a microorganism to withstand the effects of certain medications. Being resistant means that the microorganism is not affected by the medication, allowing it to survive and continue to cause infection. Choice A, unwilling, does not accurately describe the concept of resistance in medicine. Choice C, opposed to, does not capture the essence of resistance as it relates to medication effectiveness. Choice D, accepting of, is the opposite of resistance and does not align with the medical definition of the term. Therefore, the correct answer is B as it best reflects the medical context of resistance.

Correct Answer: C

Rationale: The correct answer is C: assumed. "Hypothetical" means based on an assumption or guess, not proven. It is not synonymous with "rigorous" (A), which means thorough and precise. It is also not related to "short-term" (B), which refers to a brief duration. Furthermore, "convinced" (D) implies a state of belief or certainty, which is contrary to the tentative nature of something that is hypothetical. Thus, the most suitable definition for hypothetical is "assumed" as it reflects the uncertain and speculative nature of a hypothesis.

Correct Answer: D

Rationale: The correct answer is D: Float. In the sentence, "waft" is used to describe how the dry leaves are moving gently through the air due to the breeze. To waft means to float easily through the air. Choice A, sink, is incorrect because it means to go down or descend. Choice B, dive, is incorrect as it means to plunge into water. Choice C, wave, is also incorrect as it refers to a hand gesture or a movement of the hand. Therefore, the most appropriate meaning in the context of the sentence is "float."

Correct Answer: D

Rationale: The correct answer is D: Disregard. 'Contravene' means to violate or disobey a rule, law, or order. In the given sentence, the interns are being asked if they went against or ignored the doctor's orders. The word 'comply with' (A) means to obey, which is the opposite of 'contravene'. 'Misjudge' (B) means to make an incorrect judgment, which is unrelated to disobeying orders. 'Comprehend' (C) means to understand, which does not fit the context of going against the doctor's orders. Therefore, D is the best choice as it accurately reflects the meaning of 'contravene' in the given sentence.
