HESI A2 Practice Test Vocabulary

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: B

Rationale: The correct answer is B: Residual. In the context of the sentence, 'residual' refers to something that remains or is left over. The word 'resident' (A) refers to a person who lives in a particular place, 'resistance' (C) refers to the act of opposing or withstanding something, and 'resin' (D) is a sticky substance. Therefore, B is the correct choice as it directly relates to the meaning of something that remains.

Correct Answer: C

Rationale: The correct answer is C: Threatening. The word 'ominous' is used to describe something that suggests harm or danger. In the sentence provided, the word 'ominous' is used to convey that the sign is foreboding or indicating something bad may happen. The other choices are incorrect because: A: A good omen means a sign of good luck, which is the opposite of ominous. B: Without deceit means honest or sincere, which is unrelated to the negative connotation of ominous. D: Full of thought means being contemplative or reflective, which does not align with the negative and threatening meaning of ominous.

Correct Answer: C

Rationale: The correct answer is C: Democratic leadership. In this style, the leader values input from group members, encourages participation in decision-making, and considers diverse perspectives. This approach fosters teamwork, enhances morale, and promotes a sense of ownership among team members. Laissez-faire (A) is hands-off leadership, autocratic (B) is authoritative and top-down, and direct (D) is not a recognized leadership style.

Correct Answer: C

Rationale: The correct answer is C: Gradual. In the sentence, 'insidious' describes a disease that progresses slowly and unnoticed before showing symptoms. The word 'insidious' typically implies a gradual and subtle development, unlike sudden or immediate changes. Choice A, sudden, is incorrect as 'insidious' conveys a sense of hidden or subtle rather than sudden. Choice B, suffer, is incorrect as 'insidious' does not directly relate to suffering. Choice D, graduate, is incorrect as it does not align with the context of the sentence or the meaning of 'insidious.'
