HESI A2 Practice Vocabulary

Correct Answer: B

Rationale: The correct answer is B: Shape or outline of something. Contour refers to the characteristic features or shape of an object or surface. It represents the visual representation of the topography or structure in a two-dimensional form. The other choices (A, C, D) are incorrect because contour is not about the flatness (A), volume (C), or height (D) of a structure, but rather about the specific shape or outline of the object or surface.

Correct Answer: B

Rationale: The correct answer is B because 'inflamed' refers to a localized response to tissue injury characterized by redness, swelling, and tenderness. This process involves dilation of blood vessels and increased permeability, leading to the classic signs of inflammation. Choices A, C, and D are incorrect because inflammation is not associated with being healthy and normal (A), solely discolored without swelling (C), or characterized by hardness and stiffness (D). The key to identifying the correct answer is understanding the pathological processes underlying inflammation.

Correct Answer: D

Rationale: The correct answer is D, "The spy had to snake his way onto the train." In this sentence, 'snake' is used as a verb to describe the action of moving in a winding or twisting manner. The word 'snake' is directly linked to the action of the spy maneuvering onto the train. The other choices, A, B, and C, use 'snake' as a noun to refer to the reptile itself or its movement, not as a verb. Therefore, only choice D correctly uses 'snake' as a verb in the context of an action performed by the spy.

Correct Answer: B

Rationale: The correct answer is B: Located outside the body. 'External' refers to something that is situated or occurring outside of the body. This term is commonly used in anatomy to distinguish between internal and external structures. Choices A, C, and D are incorrect because they do not accurately define the term 'External' as pertaining to something outside the body. Choice A refers to inside the body, Choice C refers to being exposed internally, and Choice D refers to being near the skin, but not necessarily outside the body.

Correct Answer: A

Rationale: The correct answer is A: Her skin has a yellow tint. Sallow skin refers to a yellowish or pale complexion, often indicating poor health or illness. This is because of decreased blood flow and oxygenation. Choice B, blue tint, is incorrect as blue skin would suggest cyanosis, related to lack of oxygen. Choice C, red tint, is incorrect as it would indicate flushed or irritated skin. Choice D, green tint, is incorrect as green skin is not a typical symptom and does not align with the definition of sallow skin.
