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 draw together. Constrict means to tighten or squeeze together, making something narrower or tighter. This is the opposite of expanding (choice A), freezing (choice C), and dissolving (choice D). Expanding means to increase in size, freezing means to solidify or become rigid, and dissolving means to blend into a liquid. Therefore, the correct answer is B because it best aligns with the definition of constrict.

Correct Answer: B

Rationale: The correct answer is B: had known. The sentence is a conditional statement about a past event that didn't happen. "Had known" is the correct past perfect form to indicate that they didn't have the knowledge before going to the beach. "Knew" (choice A and C) is simple past tense and doesn't convey the same meaning. "Could have known" (choice D) is not appropriate as it implies a possibility without certainty. Hence, choice B is the correct answer.

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: Making susceptible. Predispose means to make someone more likely or susceptible to a particular condition or disease. In this context, being overweight increases the likelihood of developing diabetes. Choices A, C, and D are incorrect because predispose does not mean preventing, avoiding, or treating a condition, but rather increasing the likelihood of it occurring.
