HESI A2 Practice Test Vocabulary
1. Another word for UNDER OBSERVATION is?
- A. Cognition
- B. Isolation
- C. Surveillance
- D. Assessment
Correct answer: C
Rationale: The correct answer is C, 'Surveillance,' which means 'under observation.' 'Cognition' (A) refers to mental processes, 'Isolation' (B) means being separated from others, and 'Assessment' (D) is the evaluation of something, none of which directly relate to being observed.
2. Which sentence contains a subject-verb agreement error?
- A. The group of students is very smart
- B. The team of players is winning
- C. The list of items is on the table
- D. The pile of books is heavy
Correct answer: B
Rationale: The correct answer is 'B: The team of players is winning.' The error in this sentence is a subject-verb agreement issue. 'Team' is a singular noun, so it should take a singular verb 'is' instead of 'are.' The subject-verb agreement rule states that singular subjects should be paired with singular verbs, while plural subjects should be paired with plural verbs. Choices A, C, and D all demonstrate correct subject-verb agreement as they correctly match singular subjects ('group,' 'list,' 'pile') with singular verbs ('is,' 'is,' 'is').
3. Which adjective best completes the sentence?
- A. More greater
- B. Great
- C. Best
- D. More greatest
Correct answer: C
Rationale: 'Best' is the correct choice because it conveys the highest quality or degree in comparison, which is appropriate in this context. The sentence is discussing the opinion of coffee experts about a particular coffee blend, indicating that it is the most superior among the options. Choices A, B, and D are grammatically incorrect or redundant. 'More greater' is incorrect due to the redundant use of 'more' and 'greater.' 'Great' is a comparative form that does not fit the superlative context required. 'More greatest' is incorrect due to the unnecessary use of 'more' alongside 'greatest,' which is already a superlative form.
4. Which word is used incorrectly? 'Which procedure for giving injections was explained thoroughly to the student nurses.'
- A. procedure
- B. was
- C. explained
- D. thoroughly
Correct answer: B
Rationale: The correct answer is 'B - was.' In the original question, 'were' is incorrectly used as the verb, which should be singular to match the singular subject 'procedure.' The subject 'procedure' requires the singular form 'was' instead of the plural form 'were.' Choices A, C, and D are all used correctly in the sentence.
5. Choose the meaning of the word 'winnowed' in the following sentence: 'One by one, the applicants were winnowed out of the group.'
- A. Escorted
- B. Separated
- C. Elevated
- D. Summoned
Correct answer: B
Rationale: In this context, the word 'winnowed' means to separate or eliminate less desirable individuals from a larger group, indicating that the applicants were being sifted out or singled out in this process. Therefore, the most appropriate meaning among the choices provided is 'separated.' 'Escorted' (Choice A) implies being accompanied or guided, which is not the intended meaning. 'Elevated' (Choice C) means raised or lifted, which does not fit the context. 'Summoned' (Choice D) suggests being called or requested to attend, which is also not the correct meaning in this context.
