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: Euthanasia. Euthanasia involves intentionally ending a patient's life, which goes against medical ethics and the Hippocratic Oath. Healthcare professionals should prioritize preserving life and providing compassionate care. Performing euthanasia undermines the trust between patients and healthcare providers. Choices A, C, and D are all essential and ethical practices in healthcare. The Heimlich maneuver is used to save choking victims, assessment is crucial for diagnosing and treating patients, and palliative care focuses on improving quality of life for terminally ill patients.

Correct Answer: B

Rationale: The dependent clause in the sentence is "as soon as the puppies were sleeping." This clause cannot stand alone as a complete sentence because it depends on the rest of the sentence for context. It starts with a subordinating conjunction "as soon as," indicating it is dependent. The verb "were sleeping" is also essential to the meaning of the sentence. Option A is incorrect as "slept" is a past tense verb, not part of a dependent clause. Option C "awake" is also incorrect as it is an adjective, not part of a dependent clause. Option D "sleep" is incorrect as it is a noun, not part of a dependent clause.

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: The correct answer is B: Present but not active or visible. Latent refers to something existing but not yet developed or visible. It implies potential that is waiting to be realized. Option A is incorrect because latent means the opposite of easily seen. Option C is incorrect as latent does not imply quick reaction. Option D is incorrect as latent implies something existing but not actively growing.
