HESI A2 Vocabulary Practice Test

Correct Answer: A

Rationale: Vacuous means lacking contents or empty. In this context, choice A (Empty) is the correct answer because vacuous specifically refers to something being devoid of substance or meaning. Choice B (Full) is incorrect as it is the opposite of vacuous. Choice C (Dense) is also incorrect as it means having parts that are close together, which is not related to vacuous. Choice D (Bright) is unrelated as it refers to something being well-lit or intelligent.

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.

Correct Answer: B

Rationale: Distal refers to a structure that is further away from the point of attachment or the origin of the body part. In this case, the correct answer is B because it accurately describes the meaning of distal. Choice A is incorrect as it describes something that is closer to the point of attachment. Choice C is incorrect as it refers to the central part of the body, not the distal part. Choice D is incorrect as it describes something on the surface of the skin, which is not related to the position of a structure in relation to its point of attachment.

Correct Answer: B

Rationale: The correct answer is B: Made worse. Exacerbated means to make a symptom or situation more severe or intense. Therefore, if a symptom is exacerbated, it is made worse. Choice A: Improving, is the opposite meaning. Choice C: Stayed the same, contradicts the definition of exacerbated. Choice D: Ameliorated means to improve or make better, which is the opposite of exacerbated.

Correct Answer: A

Rationale: The correct answer is A: hung up. In this context, "hung up" means to end a phone call abruptly. The phrase "hung up on him" indicates that she ended the call without listening or responding to him. Choices B, C, and D do not fit the context. "Picked" and "held" do not convey the action of ending a call, while "held on" means to stay connected on the call, which contradicts the situation where she was mad at him. Therefore, A is the most appropriate choice.
