HESI A2 Practice Test Vocabulary

Correct Answer: B

Rationale: The correct answer is B: Toddler. A toddler is a child typically between the ages of 1 to 3 who is just learning to walk. This term specifically refers to the developmental stage of early childhood when children are beginning to gain mobility and independence. Rationale: 1. Obese (A): This term refers to a medical condition characterized by excess body fat, which is not related to a child learning to walk. 2. Geriatric (C): This term pertains to older individuals, typically over the age of 65, and is unrelated to a small child learning to walk. 3. Hale (D): This term means healthy and robust, but it does not specifically describe a small child just learning to walk. In summary, the term "toddler" is the correct choice as it accurately describes a young child in the stage of development where they are learning to walk, while the other choices are unrelated to this developmental stage.

Correct Answer: C

Rationale: The correct answer is C: Flexible. The plumber used a flexible tube because it can bend and conform to the shape of the curved pipe, making it easier to navigate through the twists and turns. A solid or rigid tube would not be able to maneuver through the curved pipe effectively. Perforated tube has holes and would not be suitable for clearing blockages. In summary, the flexibility of the tube allows it to adapt to the shape of the pipe, making it the most appropriate choice for this task.

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: She. In this sentence, "Nurse Junko and she" is the subject performing the action. When using a compound subject, the subjective pronoun "she" must be used to refer to Nurse Junko. The subjective pronoun "she" is used for third person singular subjects, while "her" would be used for the object form. Choices B, C, and D are incorrect because they do not match the subject-verb agreement in the sentence. "Them" is plural, "Me" is first person singular, and "Him" is third person singular object form.

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.'
