HESI A2 Vocabulary Practice Test

Correct Answer: A

Rationale: The correct answer is A: Buttress. Buttressing involves providing structural support to prevent collapse. In the context of a falling fence, buttressing would involve reinforcing the weak section to prevent it from falling apart further. Degrade (B), hinder (C), and flounder (D) are all incorrect as they do not address the specific action needed to address the falling fence. Degrade means to deteriorate, hinder means to obstruct, and flounder means to struggle or fail.

Correct Answer: B

Rationale: The correct answer is B: Entering into a body part. Invasive refers to something that intrudes or penetrates into another entity. In medical terminology, it specifically refers to procedures or organisms entering the body. Choice A is incorrect because invasive doesn't imply harmlessness. Choice C is incorrect as invasive is more than just mildly irritating. Choice D is incorrect because invasive does involve penetration.

Correct Answer: B

Rationale: Step-by-step rationale: 1. "Precipitous" is often used to describe something happening quickly or suddenly. 2. The word "swift" means happening with speed and quickness. 3. Therefore, "swift" best aligns with the definition of "precipitous." Summary: - Choice A (Slow): Incorrect, as "slow" is the opposite of what "precipitous" typically means. - Choice C (Gradual): Incorrect, as "gradual" means happening slowly over time, opposite of "precipitous." - Choice D (Delayed): Incorrect, as "delayed" refers to something happening later than expected, not the suddenness of "precipitous."

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.
