HESI A2 Practice Test Vocabulary

Correct Answer: C

Rationale: Step-by-step rationale for choice C (Parasite) being correct: 1. A nit is the egg of a louse, which is a parasite that infests the hair or body. 2. Parasites are organisms that live on or in another organism (host) for nourishment. 3. Nits are commonly associated with head lice infestations. 4. Therefore, the correct answer is C (Parasite). Summary of why other choices are incorrect: - Abscess (A): An abscess is a localized collection of pus within tissues, not related to nits. - Bandage (B): Bandage is a material used for covering wounds, not related to nits. - Infection (D): Infection refers to invasion and multiplication of pathogens in the body, not specific to nits.

Correct Answer: A

Rationale: The correct answer is A: Imply. When someone implies something, they suggest or hint at it indirectly. "Imply" is the verb form of the action. Choice B, Infer, means to deduce or conclude based on evidence or reasoning, so it is the recipient of the implication. Choices C and D, Opinion and Latter, do not relate to the action of suggesting or hinting indirectly. Therefore, A is the correct choice as it directly aligns with the definition provided in the question.

Correct Answer: A

Rationale: The correct answer is A: Complex. "Convoluted" means intricate or complicated. The word itself has a negative connotation, suggesting something overly complex. Therefore, to be convoluted is to be complex in a confusing or unnecessary way. B: Clever implies intelligence or ingenuity, which does not necessarily align with the negative sense of convoluted. C: Candid means honest or straightforward, which is the opposite of convoluted. D: Asinine means foolish or silly, which is unrelated to the complexity implied by convoluted.

Correct Answer: A

Rationale: The correct answer is A: Regimen. A regimen refers to a systematic plan or set of rules to follow, which aligns with the phrase 'a system of procedures to follow'. Regime (B) typically refers to a government or ruling system, not specific procedures. Testament (C) refers to a will or statement of belief, unrelated to procedures. Treatment (D) refers to medical care or a way of dealing with something, not a set of procedures. Therefore, A is the best choice as it directly reflects the meaning of the given phrase.

Correct Answer: D

Rationale: The correct answer is D: Soon to occur. 'Impending' means about to happen or approaching. In the context of the sentence, it suggests something that is close in time. Choice A, Very serious, is incorrect as 'impending' does not imply seriousness. Choices B and C, Required and Elective, are also incorrect as they do not relate to the time factor indicated by 'impending.'
