HESI A2 Vocabulary Quizlet

Correct Answer: B

Rationale: The correct answer is B: Volatile. In this context, 'labile' means prone to change rapidly or unpredictably. The child's condition is described as labile, indicating instability. 'Fevered' (A) refers to having a fever, not capturing the changing nature. 'Stomach' (C) and 'Vision' (D) are unrelated to the context of the child's condition. Hence, 'volatile' best fits the meaning of 'labile' in this sentence.

Correct Answer: D

Rationale: The correct answer is D: Outcome statement. In the given sentence, 'prognosis' refers to the doctor's prediction or forecast about the likely outcome of the patient's condition. This is supported by the context of the sentence where the patient feels optimistic based on the doctor's prognosis. A) Instructions, B) Estimate, and C) Behavior do not accurately capture the meaning of 'prognosis' in this context. Instructions refer to directions or guidance, estimate is a rough calculation, and behavior pertains to actions or conduct, none of which align with the meaning of 'prognosis' in this specific sentence.

Correct Answer: B

Rationale: The correct answer is B: Difficult to arouse. Lethargy refers to extreme tiredness or a lack of energy, causing the patient to be difficult to arouse. Pacing the halls (A) indicates restlessness, shaking uncontrollably (C) indicates tremors, and not responding to pain (D) indicates unconsciousness, none of which are characteristic of lethargy.

Correct Answer: A

Rationale: The correct answer is A because 'fast' is used as an adverb to describe how the cars moved. Adverbs modify verbs, adjectives, or other adverbs. In this sentence, 'fast' modifies the verb 'moved'. Choice B uses 'fast' as an adjective to describe the clock, not an adverb. Choice C uses 'fast' as an adjective to describe the pitch, not an adverb. Choice D uses 'fast' as an adjective to describe the cars, not an adverb. Therefore, the sentence in choice A is the only one where 'fast' is correctly used as an adverb.

Correct Answer: A

Rationale: The correct answer is A: Were. In this sentence, the verb should be in the subjunctive mood to express a hypothetical situation. "Were" is the correct subjunctive form for the verb "to be" in the past tense when used in this context. It indicates an unreal or hypothetical situation. The other choices, B: Is, C: Be, and D: Was, are incorrect because they do not correctly represent the subjunctive mood required for hypothetical or unreal situations. "Is" is present tense, "Be" is an infinitive form, and "Was" is past tense but not the correct subjunctive form in this context.
