HESI A2 Vocabulary 2023

Correct Answer: D

Rationale: The correct answer is D: sternum. The sternum is commonly known as the breastbone in human anatomy. It is a flat bone located in the center of the chest, connecting the rib bones. The term "sternum" is derived from the Greek word "sternon," which means chest. The other choices (A: stelic, B: steres, C: sterol) are not anatomical terms related to the breastbone or chest structure, making them incorrect options in this context.

Correct Answer: B

Rationale: The correct answer is B: Dormant. Latent and dormant both refer to something existing but not actively expressed or visible. Flagrant means conspicuously offensive, making it the opposite of latent. Deceased means no longer alive, unrelated to latent. Postponed means delayed or rescheduled, not synonymous with latent. Therefore, the best synonym for latent among the choices provided is dormant.

Correct Answer: D

Rationale: The correct answer is D: Rot. Putrefy means to decay or decompose, which is synonymous with the word "rot." Choice A, Discharge, means to release or emit, which is not related to putrefy. Choice B, Harden, means to make or become hard, opposite in meaning to putrefy. Choice C, Panic, means sudden uncontrollable fear or anxiety, not related to putrefy. Therefore, D is the correct answer as it best matches the meaning of putrefy.

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: 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.
