HESI A2 Vocabulary 2023

Correct Answer: C

Rationale: The correct answer is C, at the pinnacle of success. "Zenith" means the highest point or peak, so being at the zenith of your career implies reaching the highest level of success. Choice A is incorrect as it suggests being at the beginning, which contradicts the meaning of zenith. Choice B is incorrect as it implies preparing to end one's career, which is the opposite of being at the peak. Choice D is incorrect as it suggests facing challenges with superiors, which is not necessarily related to being at the peak of success. Therefore, the best answer is C, as it aligns with the meaning of "zenith" in the context of a career.

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.

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: D

Rationale: The correct answer is D, "To move side to side." In the context of the sentence, 'yaw' refers to a horizontal movement of the robotic arm requiring adjustment. This movement aligns with the definition of yaw as a side-to-side motion, commonly used in aviation and robotics. Choice A, "To gape open," is incorrect as it does not fit the context of the sentence. Choice B, "To move up and down," does not align with the horizontal movement described. Choice C, "To close tightly," is also incorrect as it does not relate to any form of movement but rather a stationary action.

Correct Answer: A

Rationale: The correct answer is A: Permeable. Permeable describes a screen or filter because it allows substances to pass through. Screens and filters are designed to allow certain particles or substances to flow through while blocking others. Choice B, Incendiary, is incorrect as it means causing fires. Choice C, Exuding, is incorrect as it means to discharge or emit. Choice D, Resilient, is incorrect as it means able to withstand or recover from difficult conditions. The key in this question is understanding the function of a screen or filter, which is to permit the passage of some substances while blocking others, making the term "permeable" the most appropriate choice.
