Vocabulary HESI A2

Correct Answer: A

Rationale: The correct answer is A: Unsettled. In the sentence, "inconclusive" indicates that the data has not provided a definite conclusion. This aligns with the meaning of "unsettled," which implies a lack of finality or clarity. The other choices are incorrect because: - B: Convincing means something that is persuasive or compelling, which does not fit the context of the sentence. - C: Unfavorable means not beneficial or not advantageous, which is not the meaning conveyed by "inconclusive." - D: Bewildering means confusing or perplexing, which does not capture the meaning of "inconclusive" in this context.

Correct Answer: D

Rationale: The correct answer is D: Painkilling. Anodyne is a term that refers to something that relieves or alleviates pain. The term is commonly used in the context of painkillers or medications that help reduce pain. Explanation for other choices: A: Emulsified - This term refers to the process of combining two liquids that are normally immiscible. It is unrelated to the term anodyne. B: Liquefied - This term refers to the state of being in a liquid form. It is not related to the term anodyne. C: Contaminated - This term refers to something that has been polluted or made impure by foreign substances. It is not related to the term anodyne. In summary, the correct answer is D because anodyne specifically relates to pain relief, while the other choices are unrelated to the term.

Correct Answer: A

Rationale: The correct answer is A: Unstable. In the sentence, "volatile" refers to liquids that can easily evaporate at normal temperatures. Therefore, the meaning of "volatile" in this context is unstable, as these liquids can quickly change into gas form. The other choices are incorrect because: B: Abnormal - does not accurately capture the meaning of "volatile" in this context. C: Lethal - does not relate to the evaporation properties of the liquids mentioned. D: Blended - does not reflect the characteristic of being easily evaporated.

Correct Answer: C

Rationale: The correct answer is C: delirium tremens. This abbreviation is commonly used in healthcare to refer to a severe form of alcohol withdrawal characterized by confusion, agitation, hallucinations, and seizures. Deep tendon reflex (A) refers to a neurological assessment, descending thorax (B) is not a recognized medical term, and dextrose in water (D) is a solution used for intravenous administration. Therefore, C is the correct choice based on the context of patient care and medical terminology.

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.
