HESI A2 Practice Vocabulary

Correct Answer: B

Rationale: The correct answer is B: To make a liquid less concentrated. Dilute means to reduce the concentration of a substance by adding more solvent. This process results in a less concentrated solution. Choice A is incorrect because it is the opposite of dilute. Choice C, solidify, refers to the process of turning a liquid into a solid, which is not related to dilution. Choice D, evaporate, means to convert a liquid into a gas, which is also not the same as diluting a liquid. In summary, the correct answer, B, is the only choice that accurately defines the term "dilute" by describing the process of making a liquid less concentrated.

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.

Correct Answer: A

Rationale: The correct answer is A: Predict. To anticipate means to foresee or expect something to happen. Predict is synonymous with anticipate as both involve forecasting future events based on current information. Evaluate (B) means to assess or judge, Compare (C) means to identify similarities and differences, and Forestall (D) means to prevent or hinder something from happening, which are all unrelated to the meaning of anticipate.

Correct Answer: B

Rationale: The correct answer is B: Sex of an individual. Gender refers to the socially constructed roles, behaviors, expressions, and identities associated with being male or female. It is different from biological sex, which is based on physical characteristics. Choice A is incorrect because gender is not a medical condition. Choice C is incorrect as gender is not solely related to emotional state. Choice D is incorrect as gender is not a psychological term but rather a sociocultural concept.

Correct Answer: B

Rationale: The correct answer is B because 'inflamed' refers to a localized response to tissue injury characterized by redness, swelling, and tenderness. This process involves dilation of blood vessels and increased permeability, leading to the classic signs of inflammation. Choices A, C, and D are incorrect because inflammation is not associated with being healthy and normal (A), solely discolored without swelling (C), or characterized by hardness and stiffness (D). The key to identifying the correct answer is understanding the pathological processes underlying inflammation.
