HESI A2 Practice Test Vocabulary

Correct Answer: C

Rationale: The correct answer is C because the word "environment" refers to the surroundings or conditions in which a person, animal, or plant lives or operates. It encompasses both external factors (like physical surroundings, social interactions, etc.) and internal factors (like mental, emotional, and physical well-being). Choices A, B, and D are incorrect as they do not accurately capture the comprehensive nature of the term "environment." A refers more to societal concepts, B is too narrow in focus, and D is limited to a specific aspect of a home environment. Therefore, C is the most appropriate choice as it encapsulates the full scope of the term "environment."

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: C

Rationale: The correct answer is C: Flexible. The plumber used a flexible tube because it can bend and conform to the shape of the curved pipe, making it easier to navigate through the twists and turns. A solid or rigid tube would not be able to maneuver through the curved pipe effectively. Perforated tube has holes and would not be suitable for clearing blockages. In summary, the flexibility of the tube allows it to adapt to the shape of the pipe, making it the most appropriate choice for this task.

Correct Answer: B

Rationale: The correct answer is B: Reason. 'Rational' is related to reason, logic, and sound judgment. It implies making decisions based on logical thinking rather than emotions. Angry (A) does not relate to 'rational.' Rodent (C) and Proportion (D) are also unrelated to the meaning of 'rational.'

Correct Answer: A

Rationale: The correct answer is A: Gradual. In the context of disease development, "insidious" means slow and subtle in onset. This term implies a gradual progression without immediate noticeable symptoms. Choice B, momentous, means significant or important, which is not related to the gradual nature of the disease. Choice C, sudden, is the opposite of insidious, indicating a rapid onset. Choice D, innocuous, means harmless, which is not relevant to the negative connotation of insidious in disease development.
