HESI A2 Practice Vocabulary

Correct Answer: B

Rationale: The correct answer is B: Undesired, possibly harmful. Adverse means having a negative or harmful effect. This is the opposite of desirable (choice A) and beneficial (choice C). Adverse is not neutral (choice D) as it implies a negative impact. In summary, adverse specifically indicates something unwanted or harmful, making choice B the correct definition.

Correct Answer: D

Rationale: The correct answer is D, "The spy had to snake his way onto the train." In this sentence, 'snake' is used as a verb to describe the action of moving in a winding or twisting manner. The word 'snake' is directly linked to the action of the spy maneuvering onto the train. The other choices, A, B, and C, use 'snake' as a noun to refer to the reptile itself or its movement, not as a verb. Therefore, only choice D correctly uses 'snake' as a verb in the context of an action performed by the spy.

Correct Answer: B

Rationale: Step-by-step rationale for choice B: "Hindering" as the correct answer: 1. Inhibiting means to restrict, restrain, or impede progress. 2. Hindering aligns with this definition as it denotes causing delay or obstruction. 3. Blocking (choice A) implies complete stoppage, not just restriction. 4. Energizing (choice C) means to provide energy, opposite of inhibiting. 5. Slowing down improvement (choice D) is related but not as direct as hindering. In summary, "hindering" best captures the essence of inhibiting by indicating a barrier or obstacle to progress.

Correct Answer: B

Rationale: The correct answer is B: Charitable. Altruism refers to selfless concern for the well-being of others. Being charitable aligns with this definition as it involves giving to others without expecting anything in return. Choice A (Selfish) is the opposite of altruistic, focusing on self-interest. Choice C (Greedy) and D (Hateful) are also opposite in nature, as they involve a focus on personal gain or negative feelings towards others, which contradict the concept of altruism. Therefore, B is the most suitable term to describe someone who is altruistic.

Correct Answer: B

Rationale: The correct answer is B: Shape or outline of something. Contour refers to the characteristic features or shape of an object or surface. It represents the visual representation of the topography or structure in a two-dimensional form. The other choices (A, C, D) are incorrect because contour is not about the flatness (A), volume (C), or height (D) of a structure, but rather about the specific shape or outline of the object or surface.
