HESI A2 Grammar Practice Test
1. 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.
2. Select the phrase that makes the following sentence grammatically correct: 'Janet called her ____ run after a squirrel.'
- A. dog, who had
- B. dog that had
- C. dog, that had
- D. dog who had
Correct answer: A
Rationale: The correct answer is 'dog, who had.' The phrase 'dog, who had' correctly indicates that Janet called her dog to run after a squirrel. In this case, 'who had' provides additional information about the dog, making the sentence grammatically accurate. Choices B, C, and D are incorrect because they do not use the appropriate relative pronoun 'who' for referring to animals.
3. Which word is used incorrectly in the following sentence? Everybody pretends to do so, but few truly understand the essay.
- A. pretends
- B. truly
- C. understand
- D. essay
Correct answer: C
Rationale: The word 'understand' should be used instead of 'understands' to maintain subject-verb agreement. In this sentence, 'few' is a plural subject, requiring the plural verb 'understand' rather than 'understands.' The corrected sentence reads, 'but few truly understand the essay.' Choice A, 'pretends,' is used correctly in the sentence. Choice B, 'truly,' is also used appropriately. Choice D, 'essay,' is also correctly used in the sentence.
4. Select the word that makes the following sentence grammatically correct. Having ___________ one pill at bedtime, the patient was able to sleep for eight hours.
- A. took
- B. take
- C. taking
- D. taken
Correct answer: C
Rationale: The correct word to use in this sentence is 'taking' to show the continuous aspect of the action. The sentence should read: 'Having taking one pill at bedtime, the patient was able to sleep for eight hours.' 'Taking' is the present participle form of the verb 'take,' which is appropriate in this context to indicate the ongoing action of taking a pill at bedtime. Choice A, 'took,' is incorrect as it is the simple past tense, not suitable for this sentence's structure. Choice B, 'take,' is the base form of the verb, which does not fit the sentence's requirement for a participle. Choice D, 'taken,' is the past participle form, which is also unsuitable for showing the ongoing action required in this context.
5. Which word is used incorrectly in the following sentence? Jeremiah seemed enthusiastic when we reported on our astonishing success.
- A. seemed
- B. enthusiastic
- C. astonishing
- D. success
Correct answer: B
Rationale: The word 'enthusiastic' is used incorrectly in the sentence. It should be 'enthusiastic' instead of 'enthusiastically' since it is describing Jeremiah's state of being, not an action he performed. Adverbs like 'enthusiastically' are used to modify verbs, not adjectives like 'enthusiastic'. The other choices ('seemed,' 'astonishing,' 'success') are all used appropriately in the sentence and do not need any correction.
