HESI A2 Vocabulary Quizlet

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: 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.

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.

Correct Answer: B

Rationale: The correct answer is B: Abrupt. In the sentence, 'precipitous' is describing a change that happened suddenly or unexpectedly. This aligns with the definition of 'abrupt,' meaning sudden or unexpected. The other choices, A: Difficult, C: Gentle, and D: Unanticipated, do not accurately capture the meaning of 'precipitous' in the context of the sentence. 'Difficult' refers to challenges, 'gentle' suggests something calm or mild, and 'unanticipated' means not expected, none of which fully match the context of a sudden change described as 'precipitous.'

Correct Answer: B

Rationale: The correct answer is B: form. In the context of the sentence, the word "form" is not spelled correctly. The sentence describes a nurse looking for a missing patient, so the correct spelling should be "room" instead of "form." The other choices (A: patient, C: nurse, D: missing) are spelled correctly and are relevant to the context of the sentence. Therefore, the word "form" is the only one that is misspelled in this context.
