HESI A2 Vocabulary Practice Test

Correct Answer: D

Rationale: The correct answer is D: Influence. AFFECT means to have an impact or influence on something. Words like Reduce, Contaminate, and Eliminate do not convey the same meaning as AFFECT. Reduce means to make something smaller, Contaminate means to make something impure, and Eliminate means to remove or get rid of something, which are not synonymous with AFFECT. Therefore, D: Influence is the correct answer as it best captures the meaning of AFFECT in this context.

Correct Answer: B

Rationale: The correct answer is B: Outdated. Obsolete means no longer in use or relevant due to being outdated. Innovation (A) means introducing something new, effective (C) means successful in producing a desired or intended result, and advanced (D) means at a higher level of progress or development. In this context, the term 'obsolete' specifically refers to something that is no longer current or useful, making choice B the most appropriate answer.

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: A

Rationale: The correct answer is A because absorption refers to the process of nutrients moving from the digestive tube into the bloodstream for utilization by the body. This process occurs primarily in the small intestine through the villi and microvilli. Choice B is incorrect as it describes the secretion of enzymes into the stomach, which is related to digestion, not absorption. Choice C is also incorrect as it describes the absorption of water from the intestines, which is a separate process from the absorption of nutrients. Choice D is incorrect because it refers to the excretion of waste from the body, which is the opposite of absorption. Therefore, the movement of nutrients from the digestive tube into the bloodstream best defines absorption in the context of human physiology.

Correct Answer: B

Rationale: Step-by-step rationale for why "Conspiracy" (choice B) is the correct answer for the meaning of Collusion: 1. Collusion involves secret cooperation for illegal or deceitful purposes. 2. "Conspiracy" aligns with the secretive and illicit nature of collusion. 3. Cooperation (Choice A) is too broad and does not specify the clandestine aspect. 4. Separation (Choice C) and Rejection (Choice D) are unrelated to the concept of collusion.
