HESI A2 Vocabulary Practice Test

1. What does Collusion refer to?

A. Agreement
B. Conspiracy
C. Misunderstanding
D. Honesty

Correct answer: B

Rationale: Collusion refers to a secret agreement or conspiracy, often for deceitful or illegal purposes. While choices A, C, and D may involve some level of agreement or understanding, collusion specifically implies a secretive and usually dishonest arrangement, making choices A, C, and D incorrect in this context.

2. Select the meaning of the underlined word in the following sentence. The children became bellicose after too much time in the moving car.

A. Beautiful
B. Selfless
C. Tolerant
D. Quarrelsome

Correct answer: D

Rationale: The word 'bellicose' means showing aggression or a willingness to fight. In the context of the sentence, it suggests that the children became argumentative or confrontational after spending too much time in the moving car. Therefore, the correct meaning is 'quarrelsome.' Choices A, B, and C are incorrect because 'bellicose' does not mean beautiful, selfless, or tolerant. It specifically refers to a combative or aggressive behavior, which aligns with 'quarrelsome.'

3. Select the meaning of the word 'undulate' in the sentence: 'Each shiver made his muscles undulate beneath his skin.'

A. Ripple
B. Shake
C. Flatten
D. Unknot

Correct answer: A

Rationale: In this context, 'undulate' means to move in a smooth, wave-like motion. An undulation of muscles is a subtle, continuous rippling or rolling movement, making 'ripple' the most appropriate synonym in this sentence. 'Shake' (Choice B) is incorrect as it implies a more abrupt and irregular movement. 'Flatten' (Choice C) and 'Unknot' (Choice D) are unrelated to the smooth, wave-like motion described in the sentence.

4. What is the best description for the term cathartic?

A. Infested
B. Therapeutic
C. Fatiguing
D. Supplementing

Correct answer: B

Rationale: The term 'cathartic' is best described as therapeutic because it refers to something that provides emotional release or purification. It helps in relieving emotional tension, which is a therapeutic benefit. 'Infested' means being invaded by pests, 'Fatiguing' means causing tiredness or exhaustion, and 'Supplementing' means adding to or enhancing something, none of which accurately describe the term 'cathartic.'

5. What is the meaning of the word 'insidious' in the sentence 'The 'insidious' disease was well established before becoming apparent'?

A. Sudden
B. Suffer
C. Gradual
D. Graduate

Correct answer: C

Rationale: The correct answer is C: 'Gradual.' In the context provided, 'insidious' describes a disease that develops slowly and harmfully over time, without being easily noticed. Choices A, B, and D are incorrect. 'Sudden' (choice A) means something happening quickly or unexpectedly, 'Suffer' (choice B) means to experience pain or hardship, and 'Graduate' (choice D) means to successfully complete a process or course of study, none of which capture the intended meaning of 'insidious' in this context.
