HESI A2 Vocabulary Practice Test

Correct Answer: C

Rationale: The correct answer is C: Ephemeral. The word "ephemeral" means lasting for a very short time, which accurately describes a trip that the vacationer felt was too short. "Ponderous" means slow and dull, "salacious" means lustful or obscene, and "erudite" means scholarly or knowledgeable, none of which accurately describe a short trip. Therefore, C is the best choice.

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Rationale: The correct answer is B: Outdated. Obsolete means no longer in use or relevant due to being outdated.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 In this context, the term 'obsolete' specifically refers to something that is no longer current or useful, making choice B the most appropriate answer.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 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: 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.

Correct Answer: B

Rationale: The correct answer is B: The distance across the center of an object. The diameter of a circle is a straight line passing through the center, connecting two points on the circumference. It is twice the length of the radius. Choice A is incorrect as width typically refers to the measurement from side to side, not necessarily through the center. Choice C is incorrect as height is a vertical measurement, not related to the diameter of an object. Choice D is incorrect as the radius is half of the diameter, not the same.
