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: nostrum. A remedy is a substance or treatment that cures ailments. "Nostrum" is a synonym for remedy or cure, making it the most appropriate choice. A: inoculation refers to the process of introducing a vaccine to prevent disease. B: indicator is something that provides information or points out a condition, not necessarily a cure. D: serum is a component of blood and not specifically related to curing ailments. Therefore, C is the correct answer because it directly relates to the concept of a remedy curing ailments.

Correct Answer: A

Rationale: The correct answer is A: magnesium. Magnesium is an essential electrolyte in the human body, playing a crucial role in nerve function, muscle contraction, and maintaining a healthy heart rhythm. It is commonly found in bones and helps regulate blood pressure. Choice B: manganese is not a primary electrolyte in the human body, though it is an essential trace mineral. Choice C: magnetite is a type of mineral and not an electrolyte found in the human body. Choice D: manganite is a mineral compound and not an electrolyte present in the human body.

Correct Answer: D

Rationale: The correct answer is D: Authorized. In this context, "sanctioned" means the professor gave official permission or approval for the field trip. This is evident from the sentence structure where the professor is allowing or permitting the trip. Choices A, B, and C are incorrect because they do not align with the meaning of the sentence. "Organized" (A) implies planning, "Deterred" (B) means discouraged, and "Neglected" (C) means ignored, none of which fit the context of the sentence.

Correct Answer: C

Rationale: The correct answer is C: full. Replete means filled or well-supplied with something. In this context, it refers to being completely full or satisfied. Choice A (hardy) does not convey the same meaning. Choice B (quiet) and choice D (sad) are unrelated to the definition of replete, making them incorrect. Therefore, C is the best fit as it directly aligns with the definition of the word.
