HESI A2 Practice Vocabulary
1. 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.
2. What does 'Discrete' mean?
- A. Continuous
- B. Distinct or separate
- C. Mixed
- D. Combined
Correct answer: B
Rationale: The correct answer is B, 'Distinct or separate.' Discrete refers to something that is individually separate and distinct, not continuous (choice A), mixed (choice C), or combined (choice D). In mathematics and other fields, discrete items are countable and distinct from each other.
3. The most important things in my life are making money, traveling abroad, and _____.
- A. living well
- B. to live well
- C. to be happy
- D. enjoying life
Correct answer: A
Rationale: The correct answer is 'living well.' The sentence lists actions using '-ing' forms (making, traveling, and living), so 'living well' maintains parallel structure. Choice B ('to live well') breaks this structure by introducing an infinitive form. Choice C ('to be happy') introduces a new action not in parallel with the others. Choice D ('enjoying life') changes the structure and focuses on a different action not consistent with the previous activities listed.
4. Identify the correct sentence structure.
- A. The cat sleeping on the mat
- B. The cat is sleeping on the mat
- C. The mat that the cat is sleeping on
- D. Sleeping on the mat is the cat
Correct answer: B
Rationale: The correct sentence structure is 'The cat is sleeping on the mat.' This is a complete and grammatically correct sentence following a standard subject-verb-object structure. 'The cat' is the subject, 'is sleeping' is the verb, and 'on the mat' is the prepositional phrase describing where the action is taking place. Choices A, C, and D are incorrect. Option A is a sentence fragment lacking a verb; option C is a dependent clause lacking a main clause, and option D has a subject-verb inversion making it awkward and incorrect.
5. What is the best description of the word 'insidious'?
- A. stealthy
- B. deadly
- C. collapsed
- D. new
Correct answer: A
Rationale: The correct answer is A: 'stealthy.' 'Insidious' is often used to describe something that proceeds in a gradual, subtle, but harmful way. It is not directly or openly harmful like 'deadly,' nor does it mean 'collapsed' or 'new.' Therefore, 'stealthy' best captures the meaning of 'insidious.'
