HESI A2 Practice Vocabulary
1. Something that is viscous is thick and sticky. Another word for this might be ______?
- A. Watery
- B. Gelatinous
- C. Fluid
- D. Dry
Correct answer: B
Rationale: The correct answer is 'B: Gelatinous.' Viscous substances have a thick and sticky consistency, similar to the properties of gelatin. 'Watery' and 'fluid' are incorrect as they are opposite in meaning to viscous, which implies thickness and stickiness. 'Dry' is also incorrect as it does not capture the characteristic of being thick and sticky associated with viscosity.
2. Which word describes a screen or filter?
- A. Permeable
- B. Incendiary
- C. Exuding
- D. Resilient
Correct answer: A
Rationale: The word 'permeable' refers to a material or surface that allows liquids, gases, or substances to pass through it, while screening or filtering out impurities. This makes it an appropriate descriptor for a screen or filter, which function by allowing certain elements to pass through while retaining others. Choices B, C, and D are incorrect: 'Incendiary' means causing fires, 'Exuding' means giving off or releasing, and 'Resilient' means able to withstand or recover from difficult conditions.
3. What is a Nutrient?
- A. A chemical compound
- B. A substance that provides nourishment
- C. A non-essential mineral
- D. An essential vitamin
Correct answer: B
Rationale: A nutrient is a substance that provides nourishment to the body, such as carbohydrates, proteins, fats, vitamins, and minerals. Choice A has been improved to 'A chemical compound' to be more specific. Choice A is incorrect as it is too general and does not specifically describe the role of a nutrient. Choice C is incorrect as it focuses on minerals without specifying that all minerals are nutrients. Choice D is also incorrect as it solely emphasizes vitamins, which are just one type of nutrient.
4. To vivify someone is to ___________.
- A. belittle him
- B. animate him
- C. alarm him
- D. spoil him
Correct answer: B
Rationale: To vivify someone means to give life or animation to them. It involves revitalizing or energizing someone, rather than belittling, alarming, or spoiling them. Therefore, the correct answer is "animate him" as it is the most suitable synonym for vivify in this context. Choices A, C, and D are incorrect as they do not align with the meaning of vivify.
5. Which word correctly completes the sentence? 'The men and women of the graduating class ___ their caps in the air.'
- A. Thorough
- B. Through
- C. Threw
- D. Throwing
Correct answer: C
Rationale: The correct answer is 'C: Threw.' In this sentence, we need the past tense form of the verb 'throw' to show the action that occurred. Therefore, 'threw' is the correct choice. 'Thorough' (choice A) means complete or exhaustive, which doesn't fit the context of the sentence. 'Through' (choice B) is a preposition or an adverb, not the correct verb form. 'Throwing' (choice D) is the present participle form and does not match the past tense needed in the sentence.
