Vocabulary HESI A2 Practice Test
1. What is the meaning of NEBULOUS?
- A. Clear
- B. Vague
- C. Precise
- D. Obvious
Correct answer: B
Rationale: The correct answer is B, 'Vague.' Nebulous means something that is vague or unclear. Choice A, 'Clear,' is incorrect as it represents the opposite meaning of nebulous. Choice C, 'Precise,' is incorrect as it denotes clarity and exactness, which is the opposite of nebulous. Choice D, 'Obvious,' is also incorrect as it implies something that is easily understood or seen, unlike nebulous which refers to something unclear or hazy.
2. What is the correct verb to complete the sentence? 'Economics ___ my least favorite subject at school.'
- A. Is
- B. Been
- C. Am
- D. Are
Correct answer: A
Rationale: The correct answer is A: 'Is.' In this sentence, 'Economics' is being treated as a singular subject, so the verb should also be singular. 'Is' is the correct singular form of the verb to agree with the singular subject 'Economics.' Choice B, 'Been,' is incorrect because it is the past participle form of the verb 'be' and does not agree with the singular subject 'Economics.' Choice C, 'Am,' is incorrect because it is the first-person singular form of the verb 'be' and does not agree with the singular subject 'Economics.' Choice D, 'Are,' is incorrect because it is the plural form of the verb 'be' and does not agree with the singular subject 'Economics.'
3. A treatment that is detrimental is ___________.
- A. risk-free
- B. destructive
- C. agonizing
- D. effective
Correct answer: B
Rationale: A treatment that is detrimental is considered destructive because it causes harm or damage rather than benefiting the individual. In this context, 'detrimental' implies that the treatment has negative effects and is harmful rather than helpful. Choices A, C, and D are incorrect because a detrimental treatment is not risk-free, agonizing, or effective; instead, it is harmful and damaging.
4. A nit is a kind of _______.
- A. Abscess
- B. Bandage
- C. Parasite
- D. Infection
Correct answer: C
Rationale: Correct! A nit is the egg of a parasitic insect, such as a louse. This makes 'Parasite' the correct answer. An abscess (Choice A) is a swollen area within body tissue containing an accumulation of pus. A bandage (Choice B) is a strip of material used to cover and protect a wound. An infection (Choice D) is the invasion and multiplication of microorganisms in body tissues.
5. A condition that is chronic is ___________.
- A. harmless
- B. critical
- C. contagious
- D. recurring
Correct answer: D
Rationale: The correct answer is D, 'recurring.' A chronic condition is one that is ongoing or long-lasting, implying that it persists or recurs over a prolonged period of time. Choices A, B, and C are incorrect because chronicity does not necessarily imply harmlessness, criticality, or contagion; rather, it refers to the persistent or recurring nature of the condition.
