HESI A2 Practice Vocabulary
1. What is the meaning of 'Exemplary'?
- A. Disappointing
- B. Praiseworthy
- C. Ordinary
- D. Unacceptable
Correct answer: B
Rationale: The correct answer is B: 'Praiseworthy.' Exemplary is used to describe something that is commendable, outstanding, or worthy of praise. Therefore, the meaning of 'Exemplary' is praiseworthy, not disappointing, ordinary, or unacceptable. Choice A is incorrect because 'Disappointing' is the opposite of 'Exemplary.' Choice C is incorrect as 'Ordinary' does not reflect the exceptional nature of 'Exemplary.' Choice D is incorrect as 'Unacceptable' is the opposite meaning of 'Exemplary.'
2. What is the definition of adverse?
- A. Desirable
- B. Undesired, possibly harmful
- C. Beneficial
- D. Neutral
Correct answer: B
Rationale: The term 'adverse' is used to describe something that is unfavorable, unwanted, or potentially harmful. This makes choice B, 'Undesired, possibly harmful,' the correct definition. Choices A, C, and D are incorrect because they describe positive (desirable, beneficial) or neutral characteristics, which are the opposite of what 'adverse' means.
3. Which sentence uses 'etc.' grammatically correct?
- A. The list included diseases such as flu, measles, etc.
- B. The list included flu, measles, etc., and other items.
- C. The list included flu, measles, etc., diseases, and other items.
- D. The list included, flu, etc., measles, diseases, and other items.
Correct answer: A
Rationale: The correct usage of 'etc.' should follow a comma when concluding a list. Option A correctly places 'etc.' at the end of a logical list with a comma before it, following grammatical rules. In option B, a comma should be placed after 'etc.' before introducing 'and other items.' Options C and D either misplace commas or incorrectly use 'etc.' within the list.
4. Something that is viscous is thick and sticky. Another word for this might be ___________.
- A. fluid
- B. molten
- C. gelatinous
- D. malleable
Correct answer: C
Rationale: The correct word that can be used to describe something that is thick and sticky, like viscosity, is 'gelatinous.' Gelatinous refers to a substance that has a jelly-like consistency, which aligns with the characteristics of something viscous. Options A, B, and D do not accurately capture the concept of being thick and sticky. 'Fluid' implies a substance that flows easily, 'molten' refers to something melted by heat, and 'malleable' describes the ability to be shaped without breaking.
5. Select the correct definition of the word 'prognosis' in the sentence: 'The doctor’s prognosis gave the patient reason to feel optimistic.'
- A. Instructions
- B. Estimate
- C. Behavior
- D. Outcome statement
Correct answer: D
Rationale: In the context provided, 'prognosis' refers to a doctor's prediction or statement about the likely outcome of a disease or condition. This makes 'Outcome statement' the correct choice. 'Instructions' (A) are not related to prognosis. 'Estimate' (B) is a rough calculation or approximation, not a prediction of an outcome. 'Behavior' (C) refers to actions, conduct, or manner of an individual, which is not the meaning of 'prognosis' in this sentence.
