Vocabulary HESI A2

Correct Answer: A

Rationale: The correct answer is A: Effectiveness. Efficacy refers to the ability of something to produce a desired or intended result. In the context of the sentence, it is referring to how well counterfeit medicines work in achieving their intended purpose. Choice B (Significance), C (Corollary), and D (Conclusion) are incorrect as they do not capture the meaning of efficacy in this context. Significance refers to importance, corollary refers to a consequence, and conclusion refers to a final decision or judgment, none of which are synonymous with efficacy.

Correct Answer: D

Rationale: The correct answer is D: Flexible. Plastic is a synthetic material known for its ability to be easily molded and shaped. It is not related to mechanical properties (A), durability (B), or authenticity (C). Plastic's main characteristic is its flexibility, making it suitable for a wide range of applications. This choice best aligns with the defining feature of plastic material.

Correct Answer: A

Rationale: Step 1: Identify the word "prone" in the sentence. Step 2: Understand that "prone" means lying face down. Step 3: Analyze the context of the sentence ("next to the monitor"). Step 4: Determine that lying face down makes sense in this context for monitoring. Step 5: Eliminate other choices (B: Immobile, C: Face up, D: Asleep) as they do not fit the context of the sentence. Summary: The correct answer is A (Face down) because it aligns with the meaning of "prone" in the context of the sentence, while the other choices are not relevant to the scenario described.

Correct Answer: C

Rationale: The correct answer is C, gelatinous. Viscous describes a substance that is thick and sticky, similar to the consistency of gelatin. Gelatinous specifically refers to something having a jelly-like or semi-solid texture, making it a suitable synonym for viscous. A: Fluid means a substance that flows easily, which is the opposite of viscous. B: Molten refers to something heated to a liquid state, not necessarily thick or sticky. D: Malleable means capable of being shaped or formed easily, which is unrelated to the thick and sticky nature of viscosity.

Correct Answer: A

Rationale: The underlined word "margin" in the sentence refers to the edge or border of something. In this context, it specifically refers to the edge of the gingiva or gum tissue around the teeth. Therefore, the correct meaning is "A: Edge." Explanation of other choices: B: Grease - This does not relate to the context of applying gel on the gingival margin. C: Incisor - This refers to a type of tooth, not the correct meaning of "margin." D: Cavity - This refers to a hole or hollow space, not the correct meaning of "margin." In summary, the correct answer "A: Edge" is the most appropriate choice based on the context of the sentence, while the other options do not fit the meaning of the word "margin" in this context.
