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: B

Rationale: The correct answer is B: annual. In the sentence, 'once a year' indicates the frequency of the family reunion picnic, making 'annual' the most suitable choice. Biennial means once every two years (C), regular is too vague (A), and holiday doesn't specify the frequency of occurrence (D). Therefore, 'annual' best conveys the intended meaning of the sentence.

Correct Answer: A

Rationale: The correct answer is A: "Is." In the sentence, "Economics" is a singular subject, so it should be followed by the singular verb "is." "Been" (B) is past tense and doesn't match the present tense in the sentence. "Am" (C) is first-person singular, not third-person singular like the subject "Economics." "Are" (D) is plural, which doesn't agree with the singular subject. Therefore, "is" is the correct verb choice to maintain subject-verb agreement.

Correct Answer: D

Rationale: The correct answer is D, "Quickly." In this sentence, "quickly" is an adverb modifying the verb "answering." Adverbs describe how an action is done, making it the appropriate choice to describe the manner in which answering should be done. Choices A, B, and C do not function as adverbs and do not properly modify the verb in the sentence. A simply functions as an adjective, B is incomplete, and C is not a correct comparative form. Therefore, "Quickly" is the correct choice for this sentence.

Correct Answer: A

Rationale: The correct answer is A: Present on two sides. In the sentence, "bilateral" means that the weakness is affecting both hindquarters of the dog. This term is commonly used in medical contexts to indicate a condition or symptom that occurs on both sides of the body. Choices B, C, and D are incorrect because they do not accurately reflect the meaning of "bilateral" in this context. Choice B is unrelated to the concept of bilateral, while choices C and D incorrectly suggest that the weakness is only affecting one side of the dog's hindquarters.
