HESI A2 Practice Test Vocabulary

Correct Answer: D

Rationale: The correct answer is D because it clearly specifies that the door will remain unlocked only when the business is open, aligning with the original intent. Choice A is incorrect as it mandates the door to be unlocked at all times, which may pose security risks. Choice B is vague and confusing. Choice C is incorrect because the original sentence lacks clarity about when the door should be unlocked.

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: 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: C

Rationale: The correct answer is C: Threatening. The word 'ominous' is used to describe something that suggests harm or danger. In the sentence provided, the word 'ominous' is used to convey that the sign is foreboding or indicating something bad may happen. The other choices are incorrect because: A: A good omen means a sign of good luck, which is the opposite of ominous. B: Without deceit means honest or sincere, which is unrelated to the negative connotation of ominous. D: Full of thought means being contemplative or reflective, which does not align with the negative and threatening meaning of ominous.

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.
