HESI A2 Grammar Practice Exam
1. Select the word that will make the following sentence grammatically correct. The lounge needs a thorough cleaning, ________ the windows must be washed.
- A. and
- B. or
- C. but
- D. yet
Correct answer: A
Rationale: The correct answer is 'and.' The sentence requires a conjunction that shows the need for both a thorough cleaning and washing the windows. The word 'and' is used to connect two actions that must be performed, indicating a list of tasks that should be completed in the lounge. Choices B, C, and D are incorrect because 'or' would imply a choice between cleaning and washing the windows, 'but' would suggest a contrast or contradiction between cleaning and washing the windows, and 'yet' is used to show a contrast or unexpected result, which is not suitable in this context where both actions are necessary.
2. 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.
3. What word is best to substitute for the underlined words in the following sentence? The nurse left the room to look for the paperwork she had misplaced.
- A. her
- B. he
- C. his
- D. it
Correct answer: A
Rationale: The word 'her' is the best substitute for the underlined words 'the nurse' in the sentence. This substitution avoids redundancy and provides clarity by referring back to the nurse as a third-person singular pronoun, maintaining coherence and avoiding ambiguity. 'He' (choice B) and 'his' (choice C) are incorrect as they do not align with the gender of the nurse in the sentence. 'It' (choice D) is also incorrect as it does not refer appropriately to a person.
4. What punctuation is needed in the following sentence to make it correct? Follow my lead, I have been performing this procedure for years.
- A. Period
- B. Comma
- C. Exclamation point
- D. Semicolon
Correct answer: B
Rationale: The correct punctuation needed in the sentence is a comma. The sentence should be: 'Follow my lead, I have been performing this procedure for years.' The comma is necessary to separate the introductory phrase 'Follow my lead' from the main clause that follows. The other choices are incorrect because a period would create two separate sentences, an exclamation point is not suitable for the context, and a semicolon would be too strong of a punctuation mark for this sentence structure.
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.
