HESI A2 Vocabulary Quizlet

Correct Answer: A

Rationale: The correct answer is A: Head. In this sentence, the preposition "on" is used to indicate the location where the person was hit. When referring to body parts, we typically use the word directly without any prepositions. Therefore, the phrase "on head" is incorrect as it adds an unnecessary preposition. Choices C and D are also incorrect because the article "a" or "the" is not needed before the body part in this context. So, the most concise and grammatically correct phrase is "hit on head."

Correct Answer: C

Rationale: The correct answer is C: Threw. In this sentence, the verb needs to be in the past tense to match the action of tossing caps in the air. 'Threw' is the past tense form of 'throw,' which correctly conveys the action that has already taken place. Rationale: - A: Thorough means complete or detailed, which doesn't fit the context of the sentence. - B: Through is a preposition or adverb indicating movement from one side to the other, not a verb. - D: Throwing is the present participle form of 'throw,' which doesn't match the past tense context of the 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: 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: 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.
