Vocabulary for HESI A2

Correct Answer: B

Rationale: The correct answer is B: Surplus. Redundancy refers to having more than is needed, which aligns with the concept of surplus. Choice A, deficiency, is the opposite of redundancy. Choice C, delicate, is unrelated to the definition of redundancy. Choice D, abundance, is somewhat related but not as precise as surplus in the context of redundancy. In summary, the correct answer is B because redundancy specifically refers to having an excess or surplus of something.

Correct Answer: B

Rationale: The correct answer is B: Preventive measure. Precaution refers to actions taken to prevent potential harm or danger, making it synonymous with preventive measure. Choice A, routine procedure, is incorrect because not all routines are precautionary. Choice C, habit, is incorrect as habits may not necessarily be precautionary. Choice D, safeguard, is also incorrect as a safeguard is a protective measure rather than a preventive one.

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.

Correct Answer: A

Rationale: The correct answer is A: under. "Under anesthesia" is the correct phrase indicating the patient is in a state of anesthesia. "Within anesthesia" (B) is incorrect as "within" does not describe the state of being under anesthesia. "With anesthesia" (C) is incorrect because "with" does not convey the state of being under the influence of anesthesia. "Over anesthesia" (D) is incorrect as "over" does not appropriately describe the state of being under anesthesia. Thus, the correct choice is A.

Correct Answer: B

Rationale: Lethargic means lacking in energy and feeling sluggish. Exhausted is the best choice as it aligns with the definition. Active (A) is the opposite. Confused (C) and Restless (D) do not capture the essence of lethargy. In summary, B is the correct answer as it accurately reflects the state of being lethargic, while the other choices do not fit the definition.
