Vocabulary HESI A2 Practice Test

Correct Answer: A

Rationale: The correct answer is A: patient. In this sentence, the word "patient" is misspelled as "paitent." The correct spelling should be "patient." The other choices (B: physician, C: sodium, D: recommended) are all spelled correctly and are relevant to the context of the sentence. Therefore, the correct answer is A as it is the only word that is misspelled in the given sentence.

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.

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: Changing rapidly and often. Labile means easily altered, unstable, or constantly changing. This term is commonly used in psychology and medicine to describe emotions or conditions that fluctuate frequently. Choice A (Stable) is incorrect because labile implies the opposite of stability. Choice C (Unchanging) and choice D (Rarely changing) are also incorrect as they do not align with the definition of labile, which specifically denotes frequent changes.

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."
