Vocabulary HESI A2 Practice Test
1. What does the term 'counterfeit' mean?
- A. Real
- B. Fake
- C. Accurate
- D. Honest
Correct answer: B
Rationale: The correct answer is B: 'Fake.' Counterfeit refers to something that is not genuine or a copy made to deceive. Choice A, 'Real,' is incorrect because counterfeit items are not real. Choice C, 'Accurate,' is incorrect as counterfeit implies inaccuracy. Choice D, 'Honest,' is incorrect as counterfeit items are deceptive and not honest.
2. Select the meaning of the word 'precipitous' in the sentence: 'The precipitous change was considered a good thing.'
- A. Difficult
- B. Abrupt
- C. Gentle
- D. Unanticipated
Correct answer: B
Rationale: The correct answer is 'B: Abrupt.' In this context, 'precipitous' is used to describe a change that occurs suddenly or abruptly. Choice A ('Difficult') is incorrect as it does not capture the sudden nature of the change. Choice C ('Gentle') is incorrect as it conveys the opposite meaning of 'precipitous.' Choice D ('Unanticipated') is incorrect as it focuses on the element of surprise rather than the suddenness of the change.
3. The development of the disease was INSIDIOUS.
- A. Momentous
- B. Sudden
- C. Innocuous
- D. Gradual
Correct answer: D
Rationale: The term 'insidious' typically describes something that occurs gradually and subtly, often without being noticed until it has become more serious or established. Therefore, the development of the disease being insidious suggests that it was gradual, aligning best with the meaning of the word in this context. Choice A, 'momentous,' means significant or important, which is opposite in meaning to insidious. Choice B, 'sudden,' indicates something happening quickly and unexpectedly, contrary to the gradual nature of an insidious development. Choice C, 'innocuous,' means harmless or not likely to cause harm, which does not accurately reflect the negative and harmful connotation associated with an insidious disease development.
4. What is another word for toxin?
- A. Impurity
- B. Element
- C. Remedy
- D. Poison
Correct answer: D
Rationale: The correct answer is D, Poison. A toxin is a harmful substance that can cause illness or death, and poison is a synonym commonly used to refer to such substances. Choices A, B, and C are incorrect because impurity refers to something being dirty or unclean, an element is a pure substance that cannot be broken down further, and a remedy is a solution or treatment for a problem, not a harmful substance like a toxin.
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.
