HESI A2 Practice Vocabulary
1. The new mother wanted to use cloth diapers rather than disposables.
- A. Close
- B. Clothing
- C. Cloth
- D. Clothes
Correct answer: C
Rationale: The correct choice is C. Cloth because in the sentence, the new mother expressed a preference for using cloth diapers over disposables. 'Cloth' refers to a type of diaper material, and it makes sense in the context of the sentence. Choice A, 'Close,' is incorrect as it does not relate to the type of diapers being discussed. Choice B, 'Clothing,' is incorrect as it refers to garments worn on the body, not diapers. Choice D, 'Clothes,' is also incorrect as it is used for general garments, not specific to diapers.
2. What is the process of digestion?
- A. Production of enzymes
- B. The mechanical and chemical breakdown of food
- C. Absorption of nutrients in the blood
- D. Movement of enzymes
Correct answer: B
Rationale: The correct answer is B: The mechanical and chemical breakdown of food. Digestion involves breaking down food mechanically and chemically into smaller components for absorption by the body. This process occurs in the digestive system, preparing nutrients for absorption in the intestines. Choices A, C, and D are incorrect because digestion is not solely about the production of enzymes, absorption of nutrients in the blood, or movement of enzymes; it primarily involves breaking down food for nutrient absorption.
3. An inability to be lucid in the early morning means the person is unable to behave in which way?
- A. Coherent
- B. Speculative
- C. Furtive
- D. Animated
Correct answer: A
Rationale: An inability to be lucid in the early morning means the person is unable to behave in a coherent way. Lucidity refers to clarity of thought and coherence in one's behavior or speech. If someone is not lucid, they may be confused, disoriented, or unable to express themselves clearly. Therefore, the correct choice is A. Coherent. Choices B, C, and D are incorrect because being unable to be lucid does not necessarily mean the person is behaving in a speculative, furtive, or animated way.
4. What does 'Parameter' mean?
- A. A constant variable
- B. A characteristic or constant factor
- C. A measurable limit
- D. A calculated risk
Correct answer: B
Rationale: The correct answer is B: 'A characteristic or constant factor.' In the context of systems or experiments, a parameter is a fixed element that influences the behavior or outcome. It is not a variable like in choice A, which can change. Choice C, 'A measurable limit,' is incorrect as a parameter is not necessarily a physical limit but a defining factor. Choice D, 'A calculated risk,' is unrelated to the definition of a parameter.
5. I will call you when I _____ back from visiting my sister.
- A. get
- B. will get
- C. return
- D. came
Correct answer: A
Rationale: The correct answer is 'get' because it appropriately indicates a future action in the sentence. In English, when 'when' is used in future time clauses, the following verb should be in the present simple tense to indicate a future event, making 'get' the correct choice. Choices B, C, and D are incorrect. 'Will get' is redundant after 'when' in this context, 'return' is not the appropriate tense for a future action, and 'came' is in the past tense, which is not suitable for a future event.
