HESI A2 Practice Test Vocabulary

Correct Answer: C

Rationale: Rationale: 1. 'Impervious' means not affected or unaffected by something. 2. In the given sentence, it implies that the subject is not impacted by something. 3. Choices A, B, and D do not align with the meaning of 'impervious.' 4. Choice A suggests coping well, which is different from being unaffected. 5. Choice B implies enjoyment, unrelated to being unaffected. 6. Choice D suggests being very sensitive, opposite to being impervious.

Correct Answer: A

Rationale: The correct answer is A: Confirmed the truth of. The word "assured" means to make certain or confident about something. Therefore, "confirmed the truth of" is the most suitable synonym as it implies establishing certainty. The other choices are incorrect because: B: Sympathized with means to show compassion, C: Denied the truth of means to reject or oppose the truth, and D: Made known to means to reveal or inform, none of which capture the essence of being assured.

Correct Answer: C

Rationale: The correct answer is C: Surveillance. Under observation means being watched or monitored, which aligns with the definition of surveillance. Surveillance involves keeping a close watch over someone or something. Cognition (A) refers to mental processes, Isolation (B) means being separated or alone, and Assessment (D) involves evaluating or judging. These choices do not directly relate to being under observation.

Correct Answer: A

Rationale: The correct answer is A: Confinement away from the general population. Quarantine is a public health practice that separates and restricts the movement of individuals who may have been exposed to a contagious disease to prevent its spread. Choice B, specialist's care, is incorrect as it does not relate to quarantine. Choice C, experimental drug therapy, is incorrect as quarantine is about isolation, not drug treatment. Choice D, imprisonment in a rehabilitation unit, is incorrect as quarantine is a temporary isolation for health reasons, not a form of punishment or long-term confinement.

Correct Answer: A

Rationale: The correct answer is A: Breathe. When a child has a stuffy nose, it can obstruct air flow, making it difficult for them to breathe properly. Option B (Breathing) is a gerund form, not the infinitive form needed in this context. Option C (Breath) is a noun form, not a verb form. Option D (Breadth) refers to the extent or width of something, which is unrelated to the ability to breathe. Thus, A is the correct choice as it directly addresses the difficulty in breathing caused by a stuffy nose.
