HESI A2 Practice Test Vocabulary

Correct Answer: C

Rationale: The correct answer is C: "They're, their." Step 1: "They're" is a contraction for "they are," indicating the subject of the sentence having trouble. Step 2: "Their" is a possessive pronoun showing ownership of the new dog. Therefore, the correct usage is "They're having trouble with their new dog." Other choices are incorrect because: A: "There, their" - "There" is an adverb indicating a place, not suitable in this context. B: "Their, there" - Incorrect word order, as "their" should come before the verb. D: "Their, they're" - Incorrect usage of "they're" as a possessive pronoun.

Correct Answer: A

Rationale: The correct answer is A: Breathe. When a child has a stuffy nose, it can obstruct air flow, making it difficult for them to breathe properly. Option B (Breathing) is a gerund form, not the infinitive form needed in this context. Option C (Breath) is a noun form, not a verb form. Option D (Breadth) refers to the extent or width of something, which is unrelated to the ability to breathe. Thus, A is the correct choice as it directly addresses the difficulty in breathing caused by a stuffy nose.

Correct Answer: B

Rationale: The term 'residual' refers to what is left behind or remaining after a process. In the context of the sentence, it specifically refers to the urine left in the patient's bladder after voiding. Therefore, choice B, "What is left," is the correct answer. Choice A, "Measurement," is incorrect because 'residual' does not refer to the act of measuring but rather to the remaining amount. Choice C, "Total volume," is incorrect as it does not specifically address what is left behind. Choice D, "Color and clarity," is also incorrect as 'residual' does not pertain to the characteristics of the urine but rather to the quantity remaining.

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: 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.
