Vocabulary for HESI A2

Correct Answer: B

Rationale: The correct answer is B: Maintenance of body fluid. Hydration refers to the process of maintaining adequate levels of body fluid for proper bodily functions. This includes water intake, absorption, and distribution throughout the body. Choice A is incorrect because dehydration is the opposite of hydration. Choice C is incorrect as it refers to the loss, not maintenance, of water. Choice D is incorrect as draining fluids does not encompass the comprehensive concept of hydration. Maintaining body fluid balance is crucial for various physiological processes, making option B the correct choice.

Correct Answer: B

Rationale: The correct answer is B: Limp or lacking tone. Flaccid refers to a lack of firmness or stiffness in muscles or tissues. This term is used to describe a state of being weak or lacking in strength. Choice A, Rigid, is the opposite of flaccid as it means stiff or firm. Choice C, Tense, refers to being tight or strained, which is different from the relaxed and weak state of flaccid. Choice D, Swollen, means being enlarged due to fluid accumulation, which is not related to the lack of tone associated with flaccid. Thus, the correct answer is B as it best describes the meaning of flaccid.

Rationale: Contrite means feeling or expressing remorse or sorrow for one's sins or offenses. - Regretful aligns with this definition as it signifies feeling sorry or remorseful for one's actions. - Guilty implies being responsible for a wrongdoing, but not necessarily expressing remorse like contrite does. - Shameful pertains to feeling disgrace or embarrassment, which is related but not synonymous with contrite. - Pleased is the opposite of contrite as it conveys satisfaction or contentment, lacking the remorseful aspect.

Correct Answer: B

Rationale: The correct answer is B: Shape. Contours refer to the outline or boundary of an object or shape. By examining the contour, one can determine the shape of an object. Colors (A), sizes (C), and textures (D) are not directly related to contours, as contours specifically pertain to the shape or form of an object. Shapes define the external appearance of an object, making it the most appropriate choice among the options provided.

Correct Answer: C

Rationale: The correct answer is C: Experimental. The word "experimental" implies trying new methods or approaches before resorting to a standard procedure. In this context, the doctor wants to explore different options before considering a risky or invasive procedure. A: Internal - This choice does not fit the context of trying alternative methods before a procedure. It refers to something inside the body, not the nature of the procedure itself. B: Painful - This choice focuses on the potential discomfort of the procedure, which is not the main point of the sentence. The doctor is emphasizing trying other approaches first. D: Expensive - This choice does not relate to the idea of trying different methods before a procedure. The cost of the procedure is not the primary concern in this sentence.
