Vocabulary HESI A2 Practice Test

Correct Answer: B

Rationale: The correct answer is B: The noise did not affect his sleep. 'Affect' is a verb meaning to influence or have an impact on something. In this sentence, the noise did not influence his sleep, making it the correct usage. Choice A uses 'effect' incorrectly as a noun. Choice C uses 'affect' incorrectly as a future tense verb. Choice D uses 'affect' correctly but in the negative, making it incorrect.

Correct Answer: B

Rationale: The correct answer is B: Reddened or ruddy appearance. When someone is flushed, their skin appears red due to increased blood flow near the surface. This is typically caused by emotions, heat, or illness. Choice A, swollen, refers to an increase in size, not color. Choice C, discolored, implies a change in color different from redness. Choice D, pale, is the opposite of flushed, indicating a lack of color or a whitish appearance.

Correct Answer: B

Rationale: The correct answer is B: Swift. The word "precipitous" is used to describe something that happens very quickly or suddenly, often in a steep or rapid manner. It is synonymous with abrupt or hasty. Choice A (Gradual) is incorrect because it is the opposite of what "precipitous" means. Choice C (Slow) is incorrect because it implies a lack of speed or swiftness. Choice D (Delayed) is incorrect because it refers to something that happens after an expected or intended time, which is not the primary meaning of "precipitous."

Correct Answer: B

Rationale: The correct answer is B: Larynx. The larynx is commonly known as the voice box because it houses the vocal cords responsible for producing sound. It is located at the top of the trachea and plays a crucial role in speech and breathing. The other choices are incorrect because the trachea (A) is the windpipe, the pharynx (C) is the throat, and the esophagus (D) is the tube that carries food to the stomach. The larynx is specifically associated with vocalization and sound production.
