HESI A2 Practice Test Vocabulary

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.

Correct Answer: D

Rationale: The correct answer is D: Complaining. The term "querulous" means constantly complaining or whining. The word originates from the Latin word "queri," which means to complain. Therefore, a person who is querulous tends to express constant dissatisfaction or grievances. Choices A, B, and C do not accurately describe the behavior associated with being querulous. Stealing (A) involves taking something without permission, questioning (B) involves seeking information, and overeating (C) involves consuming food excessively.

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: C

Rationale: The correct answer is C: Responsible. In the context of the sentence, 'accountable' means being responsible for something. The night nursing staff has the duty to maintain and manage the records, thus they are accountable. A: Receptive - This word means open or willing to accept new ideas, not relevant in the context of being accountable for records. B: Notorious - This word means famous for something bad, which is not applicable in this scenario. D: Preoccupied with - This word means to be excessively concerned or worried about something, not synonymous with being accountable for records.

Correct Answer: C

Rationale: The correct answer is C: Preventive measure. A precaution is a preventive action taken to avoid potential harm or danger. Precautions are proactive steps to prevent negative outcomes. "Rule" (A) is too general and does not specifically imply preventative action. "Routine procedure" (B) suggests a regular process but may not necessarily be taken as a precaution. "Habit" (D) refers to a behavior done regularly and may not always be related to preventing harm. Therefore, C is the best choice as it directly relates to taking action to prevent potential risks.
