HESI A2 Practice Vocabulary

Correct Answer: B

Rationale: The correct answer is B: Difficult to arouse. 'Lethargic' means sluggish, lacking energy, and being slow to respond. This choice accurately reflects the definition of the word. Option A, active, is the opposite of lethargic. Option C, energized, is also the opposite of lethargic. Option D, wide awake, does not capture the essence of lethargy, which implies a lack of alertness or responsiveness. Therefore, option B is the most suitable choice based on the meaning of 'lethargic.'

Correct Answer: A

Rationale: The correct answer is A: get. In this sentence, "when" indicates a future time, so the present simple tense is used to express a future action. The verb "get" in the present simple tense is the appropriate form to indicate a future event. The other choices (B: will get, C: return, D: came) are considered incorrect because "will get" uses unnecessary future tense, "return" is not the appropriate verb to indicate a future action, and "came" is in the past tense which does not match the future context of the sentence.

Correct Answer: B

Rationale: The correct answer is B: effect. In this sentence, "effect" is the most appropriate choice as it refers to the consequence or outcome of the weather conditions, which is getting wet. The term "result" (A) is more commonly used to indicate the outcome of an action or event. "Affect" (C) is a verb meaning to influence or produce a change, not a noun to describe the outcome. "Impact" (D) is usually used to describe a strong or significant effect, but in this context, "effect" is more suitable as it directly conveys the consequence of the weather conditions.

Correct Answer: B

Rationale: The correct answer is B because digestion involves both mechanical (chewing, grinding) and chemical (enzymes, acids) breakdown of food into smaller molecules for absorption. Enzymes play a crucial role in breaking down macromolecules. Choices A, C, and D are incorrect as they do not encompass the entire process of digestion. Production of enzymes (A) is only one aspect, absorption of nutrients (C) is a separate step following digestion, and movement of enzymes (D) is not the primary focus of the digestion process.

Correct Answer: B

Rationale: The correct answer is B: Incurable. "Incorrigible" means not able to be corrected or reformed. This is because the prefix "in-" signifies negation, and "corrigible" means capable of being corrected. Therefore, the term "incorrigible" refers to something that cannot be changed or corrected. Choices A, C, and D are incorrect because they suggest the opposite meanings - curable, treatable, and temporary, respectively - which do not align with the definition of "incorrigible."
