Grammar for HESI A2
1. Select the word or phrase that makes the following sentence grammatically correct: I was extremely surprised ___________ of her dismissal from the staff.
- A. learning
- B. to learn
- C. of learning
- D. have learned
Correct answer: B
Rationale: The correct phrase to use with 'surprised' in this sentence is 'to learn.' In this context, 'to learn' functions as an infinitive to indicate the purpose or reason for the surprise. 'Learning' (Choice A) is incorrect as it doesn't serve as an infinitive in this sentence. 'Of learning' (Choice C) is incorrect as it doesn't provide the correct structure needed in the sentence. 'Have learned' (Choice D) is incorrect because the verb tense does not match the context of the sentence.
2. Select the word or phrase that makes this sentence grammatically correct: 'Children ____ obey their parents tend to do better in school.'
- A. who
- B. which
- C. should
- D. to
Correct answer: A
Rationale: In this sentence, 'who' is the correct pronoun to refer to 'Children,' indicating that children are the ones who obey their parents. Using 'who' makes the sentence grammatically correct by connecting the subject 'children' with the verb 'obey.' The pronoun 'which' is used for things, not people, so it is incorrect. 'Should' and 'to' do not fit in the context of the sentence and do not provide the necessary connection between 'children' and 'obey.' Therefore, the correct choice is 'who.'
3. Which word is used incorrectly in the following sentence? If you calculate too quickly, you may possibly fail to get the right answer.
- A. calculate
- B. quickly
- C. possibly
- D. right
Correct answer: B
Rationale: The word 'quickly' is used incorrectly in the sentence. The correct word that should be used here is 'speedily.' 'Quickly' is an adverb that describes the speed at which an action is performed. However, in this context, the sentence needs an adverb that conveys doing something in a hurried or rushed manner, which is 'speedily.' Therefore, the sentence should read as: 'If you calculate too speedily, you may possibly fail to get the right answer.' The other choices ('calculate,' 'possibly,' 'right') are used appropriately in the sentence and do not need to be changed.
4. Which word is used incorrectly in the following sentence? The professor was once an intern in this hospital back in the 1980s.
- A. professor
- B. once
- C. intern
- D. hospital
Correct answer: B
Rationale: In the given sentence, the word 'once' is used incorrectly. The original sentence implies that the professor was an intern in the hospital at a specific time in the past, not just once. The word 'formerly' would imply that the professor used to be an intern but is no longer. Therefore, 'once' is the incorrect word choice in this context. The other options ('professor,' 'intern,' 'hospital') are all used correctly in the sentence.
5. In the following sentence, which word or phrase is the subject: 'The nurses went to the conference room.'
- A. conference
- B. went to
- C. room
- D. nurses
Correct answer: D
Rationale: In the sentence, 'The nurses went to the conference room,' 'nurses' is the subject. The subject of a sentence is typically the noun or pronoun that carries out the action or is described in the sentence. In this case, 'nurses' is the noun performing the action of going to the conference room. Choices A, B, and C are not the subject. 'Conference' and 'room' are objects of the prepositions 'to' and 'the,' while 'went to' is the verb phrase indicating the action performed by the subject.
