Vocabulary for HESI A2

Correct Answer: B

Rationale: The correct answer is B: Effectiveness. Efficacy refers to the ability of a medicine to produce a desired effect or result under ideal conditions. In this context, it specifically relates to how well the new medicines work in achieving their intended purpose. Choice A, Cost, is not relevant to efficacy. Choice C, Quality, focuses on the overall standard of the medicines, not their effectiveness. Choice D, Usage, pertains to how the medicines are administered, which is different from their efficacy in producing desired outcomes.

Correct Answer: B

Rationale: The correct answer is B: To expel feces. 'Defecate' refers to the act of eliminating solid waste from the body. This process involves the expulsion of feces from the digestive system through the rectum. It is the opposite of retaining feces (choice A), eliminating fluid (choice C), or excreting mucus (choice D). Defecation specifically refers to the elimination of solid waste material, not fluids or mucus. Therefore, the most accurate choice is B.

Correct Answer: B

Rationale: To STANCH a wound means to stop or restrict the flow of blood. Therefore, the correct answer is B: Restrict. This choice aligns with the definition of stanching in the context of wound care. The other choices are incorrect because expanding (A) would not stop the flow of blood, releasing (C) implies letting go rather than stopping, and avoiding (D) does not address the immediate need to stop the bleeding.

Correct Answer: B

Rationale: Lethargic means lacking in energy and feeling sluggish. Exhausted is the best choice as it aligns with the definition. Active (A) is the opposite. Confused (C) and Restless (D) do not capture the essence of lethargy. In summary, B is the correct answer as it accurately reflects the state of being lethargic, while the other choices do not fit the definition.

Correct Answer: B

Rationale: The correct answer is B: So gradual as to not become apparent for a long time. 'Insidious' typically describes something that progresses slowly and subtly, often leading to harmful consequences that may not be immediately noticeable. This choice aligns with the commonly accepted definition of the term. A: Immediate and obvious - This choice is incorrect as 'insidious' implies the opposite of being immediate and obvious. C: Sudden and severe - This choice is incorrect as 'insidious' does not convey the idea of suddenness but rather gradual progression. D: Quick and detectable - This choice is incorrect as 'insidious' does not imply something that is quick and easily detectable.
