Grammar for HESI A2
1. Select the word that makes the following sentence grammatically correct: The centrifuge cannot run by ___________; it requires constant attention.
- A. oneself
- B. itself
- C. herself
- D. themselves
Correct answer: B
Rationale: The correct answer is 'itself.' The sentence is referring to the centrifuge, which is an object, not a person. Therefore, the word 'itself' is used to indicate that the centrifuge cannot run on its own; it requires constant attention. Choices A, C, and D are incorrect because they refer to a person or people, which is not suitable in the context of the sentence.
2. Select the word that will make the following sentence grammatically correct. The patients are resting comfortably; ___________, bed checks should still be done every half hour.
- A. despite
- B. however
- C. otherwise
- D. afterward
Correct answer: C
Rationale: The word 'otherwise' is used to indicate that although the patients are resting comfortably, under different circumstances, bed checks should still be done every half hour. This maintains the correct logic and flow of the sentence, making it grammatically correct. Choice A, 'despite,' would imply a contrasting situation that is not the intended meaning in this context. Choice B, 'however,' also implies a contrast rather than the intended conditional relationship. Choice D, 'afterward,' indicates a time sequence that does not fit the context of the sentence.
3. Select the phrase that makes the following sentence grammatically correct: I hope that my parents ___________ if I am able to graduate early.
- A. are delighted
- B. were delighted
- C. will be delighted
- D. will have been delighted
Correct answer: C
Rationale: The correct answer is C: 'will be delighted.' In this context, the sentence is expressing a future possibility of graduating early, so the phrase 'will be delighted' in the future tense is the most appropriate choice to match the context. Choices A, B, and D are incorrect because they do not convey the future tense needed in this sentence. Choice A ('are delighted') is in the present tense, choice B ('were delighted') is in the past tense, and choice D ('will have been delighted') uses a more complex future perfect tense which is not necessary in this context.
4. What word is best to substitute for the underlined words in the following sentence? The coats hanging on the hooks are the patients’.
- A. his
- B. their
- C. them
- D. theirs
Correct answer: B
Rationale: The word 'their' is the correct possessive pronoun to use in this sentence because it indicates that the coats belong to multiple patients. 'Their' shows ownership by a plural group, which is the most suitable choice in this context. Choice A, 'his,' is singular and would imply that all the coats belong to one male patient, which is not the case. Choice C, 'them,' is a pronoun used for indicating objects or people and not possession. Choice D, 'theirs,' is a possessive pronoun but is used to refer to something that belongs to multiple people, not in this case where the coats belong to the patients.
5. What punctuation is needed in the following sentence to make it correct? Do not be afraid to ask questions in his class, he is very approachable and explains things well.
- A. Hyphen
- B. Comma
- C. Apostrophe
- D. Semicolon
Correct answer: B
Rationale: The correct punctuation needed in the given sentence is a comma after 'class.' This comma is necessary to separate the two independent clauses 'Do not be afraid to ask questions in his class' and 'he is very approachable and explains things well.' Commas are used to separate independent clauses when they are joined by a coordinating conjunction like 'and.' Choice A, 'Hyphen,' is incorrect as a hyphen is not needed to connect any words in the sentence. Choice C, 'Apostrophe,' is incorrect as there is no possession or contraction being indicated in the sentence that requires an apostrophe. Choice D, 'Semicolon,' is incorrect as a semicolon is not used to join two independent clauses in this context; a comma followed by a coordinating conjunction is more appropriate.
