HESI A2 Vocabulary Practice Test

Correct Answer: B

Rationale: The correct answer is B: Uneven. Asymmetric means lacking symmetry or not being identical on both sides. Uneven accurately reflects this definition. Even (A), Identical (C), and Matching (D) all imply symmetry or uniformity, which is the opposite of asymmetric. Therefore, they are incorrect choices.

Correct Answer: C

Rationale: Rationale: 1. Contemplating means deep thinking or reflecting. 2. Pondering also means to reflect or consider deeply. 3. Impasse means a deadlock or stalemate, not related to contemplating. 4. Impartial means unbiased, not directly related to contemplating. 5. Emending means to make corrections, not synonymous with contemplating. Summary: - A (Impasse) and D (Emending) are incorrect as they do not relate to contemplating. - B (Impartial) is incorrect as it does not represent the act of deep thinking. - C (Pondering) is correct as it directly aligns with the meaning of contemplating, involving thoughtful consideration.

Correct Answer: A

Rationale: The correct answer is A: of. The phrase "within 24 hours of administration" indicates a specific time frame after the administration of the tuberculin skin test. The preposition "of" in this context signifies the relationship between the time frame (24 hours) and the event (administration of the test). Using "before" (B), "after" (C), or "during" (D) would change the meaning of the sentence and imply a different timing relationship, which is not accurate in this context. Therefore, choice A is the correct preposition to use in this sentence.

Correct Answer: A

Rationale: Concave means curving inward, creating a hollow or "caved-in" shape. So, choice A "Rounded inward" is correct. Choice B "Rounded outward" is incorrect as it describes a convex shape. Choice C "Straight" is incorrect as concave implies a curved surface. Choice D "Flat" is incorrect as it does not describe a curved shape.

Correct Answer: B

Rationale: The correct answer is B: Confinement away from the general population. Quarantine refers to the isolation of individuals who may have been exposed to a contagious disease to prevent the spread to others. This choice is correct because quarantine involves separating potentially infected individuals from the rest of the population. Choice A (Isolation) is similar but not specific to disease control measures. Choice C (Treatment) does not capture the concept of separation. Choice D (Exposure) is incorrect as quarantine is about preventing exposure, not promoting it.
