HESI A2 Vocabulary Practice Test

Correct Answer: A

Rationale: The correct answer is A because "the thief" indicates a singular person, so the pronoun "he" should be used. The subject-verb agreement is crucial in this sentence. Choice B uses "he" correctly but includes a different verb. Choices C and D use the incorrect pronoun "they," which does not agree with "the thief." Additionally, "hid" in choice C is not the appropriate action after robbing a bank, and "fled" in choice D is plural and doesn't match with "the thief." Therefore, option A is the correct choice based on subject-verb agreement and logical consistency.

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: Produced within the body. Endogenous refers to something that originates or is produced internally by the body. In this context, endogenous substances are naturally produced by the body's cells or organs. Choices A, C, and D are incorrect because endogenous specifically refers to internal production and is not related to being produced outside the body, taken from an external source, or linked to environmental factors. Therefore, the correct choice is B as it accurately reflects the definition of endogenous.

Correct Answer: A

Rationale: The correct answer is A because it follows the structure of passive voice (subject + to be verb + past participle). In this sentence, "The homework was completed by the student," the focus is on the action being done to the homework rather than the student doing the action. In contrast, choices B, C, and D are in active voice where the subject performs the action. B states "The student completed the homework," C states "The teacher is grading the papers," and D states "The store opens at 9 AM." These choices clearly show the subjects performing the actions, making them in active voice.

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.
