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: She was going to the store. Rationale: "Was going" is the correct past progressive form of the verb "go" in this sentence, indicating an ongoing action in the past. "She was going" is grammatically correct. Summary: A: Incorrect - This choice is the same as the correct answer, but it is listed as a separate option. C: Incorrect - This choice uses the present perfect tense "has gone" which is not suitable for the context of the sentence. D: Incorrect - This choice uses the incorrect past participle form "gone" without the auxiliary verb "has" or "had".

Correct Answer: A

Rationale: The correct answer is A: 2-sided. The term "bilateral" is derived from the Latin words "bi" meaning two and "lateral" meaning side. Therefore, "bilateral" refers to having two sides or aspects. This term is commonly used in various contexts such as bilateral agreements, bilateral symmetry in biology, and bilateral trade. The other choices are incorrect because "straight" and "on one side" do not capture the essence of the term "bilateral," while "symmetrical" is close but not precise enough to define the specific meaning of bilateral as referring to having two sides.

Correct Answer: B

Rationale: The correct answer is B: To expel feces. 'Defecate' refers to the act of eliminating solid waste from the body. This process involves the expulsion of feces from the digestive system through the rectum. It is the opposite of retaining feces (choice A), eliminating fluid (choice C), or excreting mucus (choice D). Defecation specifically refers to the elimination of solid waste material, not fluids or mucus. Therefore, the most accurate choice is B.

Correct Answer: B

Rationale: To STANCH a wound means to stop or restrict the flow of blood. Therefore, the correct answer is B: Restrict. This choice aligns with the definition of stanching in the context of wound care. The other choices are incorrect because expanding (A) would not stop the flow of blood, releasing (C) implies letting go rather than stopping, and avoiding (D) does not address the immediate need to stop the bleeding.
