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. What does 'Parameter' mean?

A. A constant variable
B. A characteristic or constant factor
C. A measurable limit
D. A calculated risk

Correct answer: B

Rationale: The correct answer is B: 'A characteristic or constant factor.' In the context of systems or experiments, a parameter is a fixed element that influences the behavior or outcome. It is not a variable like in choice A, which can change. Choice C, 'A measurable limit,' is incorrect as a parameter is not necessarily a physical limit but a defining factor. Choice D, 'A calculated risk,' is unrelated to the definition of a parameter.

3. What does 'Occluded' mean?

A. Open
B. Closed or obstructed
C. Partially obstructed
D. Expanded

Correct answer: B

Rationale: The term 'Occluded' means something is closed or obstructed, not open as in choice A. It is more than just partially obstructed as in choice C. It does not mean expanded as in choice D. Therefore, the correct answer is B, 'Closed or obstructed.'

4. Caudal refers to which part of the human torso?

A. Top
B. Bottom
C. Middle
D. Front

Correct answer: B

Rationale: Caudal refers to the bottom part of the torso. In anatomical terms, 'caudal' means situated near or toward the tail or the hind part of the body. This term is commonly used in anatomy to describe structures closer to the feet or lower part of the body. Therefore, 'Bottom' is the correct answer as it best represents the caudal region. Choices 'Top,' 'Middle,' and 'Front' do not accurately describe the caudal aspect of the human torso.

5. The patient made a ritual of arranging the food on his plate. Which word best describes the patient's behavior of arranging the food on his plate?

A. Formal
B. Ritualistic
C. Formalizing
D. Ritual

Correct answer: B

Rationale: The word 'ritualistic' is an adjective that describes actions or behaviors performed in a habitual or symbolic manner, often resembling a ritual. In this context, it best describes the patient's behavior of repeatedly and meticulously arranging food on the plate. 'Formal' (Choice A) does not capture the habitual or symbolic aspect of the behavior. 'Formalizing' (Choice C) is a verb form and does not describe the behavior itself. 'Ritual' (Choice D) is a noun and does not fit as well here since the question is asking for an adjective to describe the behavior.
