HESI A2 Vocabulary Quizlet

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: 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: C

Rationale: The correct answer is C: Unseemly. 'Untoward' in this context means inappropriate or improper, which aligns with the negative impact the person's actions had on the nurse. It suggests behavior that is unfavorable or not socially acceptable. A: Violent is incorrect as 'untoward' does not imply physical aggression. B: Casual is incorrect as 'untoward' conveys a sense of seriousness or impropriety, not nonchalant behavior. D: Capricious is incorrect as 'untoward' does not indicate erratic or impulsive behavior, but rather behavior that is unsuitable or inappropriate.

Correct Answer: A

Rationale: The correct answer is A: Produced outside the body. In the sentence, 'exogenous factors' refer to external elements that come from outside the body and can impact the patient's well-being. This term is commonly used in medicine and biology to differentiate between factors originating externally versus internally. Choices B, C, and D are incorrect as they do not align with the context of the sentence. Option B refers to factors produced within the body, option C specifies the kidneys which is not relevant in this context, and option D refers to hereditary factors which are inherited and not necessarily external.

Correct Answer: A

Rationale: The correct answer is A: Obstructed. In the context of the sentence, 'occluded' means blocked or obstructed. An occluded artery refers to a blocked artery, typically due to a buildup of plaque or a blood clot. This impedes blood flow and can lead to serious health issues. The other choices, B: Open, C: Broken, and D: Cloudy, do not accurately capture the meaning of 'occluded' in the given context. 'Open' implies the opposite of occluded, 'Broken' is unrelated to artery blockage, and 'Cloudy' does not convey the concept of blockage or obstruction.
