HESI A2 Practice Test Vocabulary

Correct Answer: C

Rationale: The correct answer is C: Contour. Plastic surgery often focuses on enhancing the shape and structure of facial features, which is captured by the term "contour." "Bearing" refers to one's posture or demeanor, not facial appearance. "Serenity" pertains to a state of calmness, unrelated to physical changes. "Cataract" is a medical condition affecting the eyes, not relevant to plastic surgery outcomes. Therefore, "Contour" is the most appropriate choice in the context of improving facial aesthetics through plastic surgery.

Correct Answer: D

Rationale: The correct answer is D: Discharge. Flux refers to the process of flowing or continuous change. Discharge aligns with this definition as it signifies the release or movement of something, reflecting the idea of flow or change. Quantity (A) refers to amount, Inflation (B) refers to a rise in prices, and Strength (C) refers to power or energy, none of which directly relate to the concept of flux.

Correct Answer: A

Rationale: The correct answer is A: Prefix. A prefix is a word part placed before a base word to change its meaning. It comes before the root word and alters its definition. Prefixes are essential in forming new words and expanding vocabulary. Choice B: Affix is a broad term that refers to both prefixes and suffixes. While technically correct, it is not as specific as prefix in this context. Choice C: Suffix is a word part placed after a base word to change its meaning. It is the opposite of a prefix. Choice D: Vocab is short for vocabulary and does not relate to the word part placed before a word to change its meaning.

Correct Answer: D

Rationale: The correct answer is D: Obstructed. In the context of the sentence, 'occluded' refers to a blockage or obstruction in the circulation to the foot. The term is commonly used in medical scenarios to indicate a complete or partial blockage of blood flow. This choice is correct because it accurately reflects the meaning of 'occluded' in the given context. Explanation of why other choices are incorrect: A: Normal - This choice is incorrect because 'occluded' does not mean normal; it implies a restriction or blockage. B: Impaired - While 'impaired' suggests a degree of limitation, it does not fully capture the meaning of 'occluded' as a complete obstruction. C: Inadequate - Although 'inadequate' implies insufficiency, it does not specifically convey the idea of a blockage as 'occluded' does.

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.
