HESI A2 Vocabulary 2023

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: 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: stretch. When tubes distend, they expand or elongate due to internal pressure or force applied. This leads to stretching of the tube material. Flexing (choice A) implies bending, which is not the primary response when tubes distend. Solidifying (choice C) means to become solid, which is the opposite of what happens when tubes distend. Collapsing (choice D) is the opposite of stretching and occurs when tubes lose their internal pressure or support, leading to a decrease in size.

Correct Answer: C

Rationale: The correct answer is C: Gums and teeth. When people masticate, they use their gums to hold the food in place and their teeth to break down the food into smaller pieces through chewing. This process is essential for digestion. Choices A, B, and D are incorrect because fingers, eyes, ears, heels, and toes are not involved in the mastication process.

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.
