Vocabulary HESI A2

Correct Answer: A

Rationale: The correct answer is A: Unstable. In the sentence, "volatile" refers to liquids that can easily evaporate at normal temperatures. Therefore, the meaning of "volatile" in this context is unstable, as these liquids can quickly change into gas form. The other choices are incorrect because: B: Abnormal - does not accurately capture the meaning of "volatile" in this context. C: Lethal - does not relate to the evaporation properties of the liquids mentioned. D: Blended - does not reflect the characteristic of being easily evaporated.

Correct Answer: B

Rationale: The correct answer is B: Respectfully. Deferentially means showing respect or submission. Therefore, the synonym for deferentially should also convey the idea of showing respect. Choice A, Imperfectly, does not match the meaning of deferentially. Choice C, Competently, and Choice D, Energetically, do not relate to the respectful or submissive connotation of deferentially. Thus, B, Respectfully, is the most appropriate synonym for deferentially.

Correct Answer: A

Rationale: The correct answer is A: larynx. The voice box is commonly known as the larynx anatomically. It houses the vocal cords that produce sound when air passes through them. The larynx plays a crucial role in speech production. Choice B: lynx, is a type of wild cat and not related to the voice box. Choice C: pharynx, is a part of the throat responsible for swallowing, not for sound production. Choice D: phalanx, refers to the bones in the fingers and toes, not related to the voice box.

Correct Answer: A

Rationale: The correct answer is A: vital signs. These are physiological measurements that indicate the body's essential functions. Pulse, temperature, and respiration are crucial indicators of a person's overall health status. Vital statistics (choice B) refer to data related to births, deaths, marriages, etc. Vital force (choice C) is a concept in alternative medicine and vital capacity (choice D) is a measure of the maximum amount of air a person can expel from the lungs.

Correct Answer: D

Rationale: The correct answer is D: Distinctive. The sentence describes a liquid with a peculiar, unique odor, indicating that it has a characteristic that makes it stand out or be easily recognizable. "Distinctive" fits this description perfectly. A: Aerated means to introduce air into a substance, which is not relevant to the context of the sentence. B: Incapacitating means to deprive someone of strength or ability, which is not related to the description of the liquid. C: Delicate means fragile or easily broken, which does not describe the liquid in the sentence. In summary, the word "distinctive" best captures the essence of the liquid being described, making it the correct choice over the other options.
