HESI A2 Practice Test Vocabulary

Correct Answer: A

Rationale: The correct answer is A: Refrain. To abstain means to hold oneself back from doing something, similar to refraining from it. Indulge (B) means to allow oneself to enjoy something, opposite of abstain. Adhere (C) means to stick to or follow something, not related to abstaining. Eliminate (D) means to remove or get rid of something, not synonymous with abstain. Therefore, A is the most appropriate synonym for abstain.

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: D

Rationale: The correct answer is D: Right. In the United States, drivers drive cars on the right side of the road. This is in accordance with the standard traffic flow direction in the country, where vehicles keep to the right side of the road. Choosing A, B, or C would be incorrect as they do not align with the established traffic rules and regulations in the United States. Driving on the right side ensures orderly traffic flow and reduces the risk of accidents. It is important for drivers to adhere to this rule to maintain safety on the roads.

Correct Answer: B

Rationale: The correct answer is B: Destructive. 'Pernicious' means causing harm in a subtle or gradual way. It is commonly used to describe something that has a destructive or harmful effect. The word 'valued' (A) means cherished or esteemed, not harmful. 'Finicky' (C) means overly picky or fussy, not harmful. 'Perpetual' (D) means constant or never-ending, not necessarily harmful. Therefore, the most appropriate choice is B as it aligns with the definition and common usage of 'pernicious.'

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.
