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: C

Rationale: The correct answer is C: Soothing. In the sentence, "palliative care" refers to care that focuses on relieving symptoms and improving the quality of life for patients with serious illnesses. Palliative care aims to provide comfort and alleviate suffering, hence the meaning of "soothing." Choice A, scientific, is incorrect because palliative care is not primarily based on scientific methods. Choice B, surgical, is incorrect as palliative care does not typically involve surgical procedures. Choice D, serious, is incorrect as it does not capture the essence of providing comfort and relief in palliative care.

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: 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.

Correct Answer: D

Rationale: The correct answer is D: ulcer. An ulcer is a sore with disintegration of tissue, typically due to poor blood flow or infection. Allergy (A) is a hypersensitive reaction, not related to tissue disintegration. Erythema (B) refers to redness of the skin, not tissue disintegration. Alopecia (C) is hair loss, not related to tissue disintegration. In summary, an ulcer is the most appropriate term for a sore characterized by tissue disintegration.
