HESI A2 Practice Vocabulary

Correct Answer: B

Rationale: Step-by-step rationale: 1. A parameter is a characteristic or constant factor that defines a system. 2. It is not a constant variable (A) as it is not subject to change within a given context. 3. It is not a measurable limit (C) but rather a defining aspect of a system. 4. It is not a calculated risk (D) as it is not related to potential outcomes, but rather a fixed element. In summary, choice B is correct as a parameter is a specific, unchanging factor that characterizes a system, while the other choices do not accurately define the term.

Correct Answer: B

Rationale: The correct answer is B: Located within the body. 'Internal' refers to something situated inside the body, such as organs or tissues. It is the opposite of external, which is outside the body. Choices A, C, and D are incorrect because they do not accurately define 'internal.' Choice A refers to superficial locations, Choice C implies external positioning, and Choice D indicates a distance away from the body. Therefore, the correct answer is B as it aligns with the definition of 'internal' as something within the body.

Correct Answer: B

Rationale: The correct answer is B: Front. "Anterior" refers to the front part of the human body. In anatomical terms, anterior means situated at or directed toward the front. It is the opposite of "posterior," which refers to the back part. Choice A (Back) is incorrect as it refers to the opposite direction. Choice C (Side) is incorrect as it refers to a different orientation. Choice D (Top) is incorrect as it refers to the upper part, not the front. In summary, the term "anterior" specifically indicates the front part of the body, making option B the correct choice.

Correct Answer: A

Rationale: The correct answer is A: no. The sentence indicates that the person ate four pieces of fried chicken, suggesting that there were no vegetables consumed. The word "no" is the appropriate choice to convey the absence of vegetables. Choices B, C, and D imply some quantity of vegetables, which contradicts the information given in the sentence. Therefore, option A is the most suitable answer to maintain the logical consistency of the statement.

Correct Answer: B

Rationale: The correct answer is B: Located outside the body. 'External' refers to something that is situated or occurring outside of the body. This term is commonly used in anatomy to distinguish between internal and external structures. Choices A, C, and D are incorrect because they do not accurately define the term 'External' as pertaining to something outside the body. Choice A refers to inside the body, Choice C refers to being exposed internally, and Choice D refers to being near the skin, but not necessarily outside the body.
