HESI A2 Vocabulary 2023

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.

Correct Answer: B

Rationale: The correct answer is B: Water that is lukewarm. Tepid bathwater refers to water that is neither too hot nor too cold, but rather at a moderate or lukewarm temperature. This is the ideal temperature for bathing as it is comfortable and soothing. Choice A is incorrect because tepid water is not salty. Choice C is incorrect because tepid water is not icy; it is warmer than cold water. Choice D is incorrect because tepid water refers to the temperature of the water, not the quantity.

Correct Answer: D

Rationale: The correct answer is D: Lasting a long time. In the sentence, 'persistent' is used to describe the cold that the elderly patient has been fighting, indicating that the cold has been ongoing and enduring. This aligns with the definition of 'persistent' as something that continues for an extended period. Choices A, B, and C are incorrect because 'persistent' does not mean typical, harmless, or without a cure in this context. The key to selecting the correct answer is understanding the context in which the word is used and its meaning in relation to that context.

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: D

Rationale: The correct answer is D: Apprehension. In the given sentence, the word 'trepidation' is used to describe the students' feeling towards approaching the cadaver, indicating a sense of fear or nervousness. Apprehension aligns with this context as it signifies a feeling of anxiety or unease. A: Wonder - This choice is incorrect as 'wonder' conveys a sense of curiosity or amazement, which is not the intended meaning in this sentence. B: Confusion - This choice is incorrect as 'confusion' implies a state of being puzzled or unclear, which does not match the context of the sentence. C: Eagerness - This choice is incorrect as 'eagerness' suggests a feeling of enthusiasm or excitement, which is opposite to the fear or hesitation implied by 'trepidation' in this context. Therefore, the correct answer is D: Apprehension, as it best reflects the students' feelings of fear or anxiety when
