HESI A2 Grammar Practice Exam

1. Select the word that makes the following sentence grammatically correct. One of the students ___________ completed the course.

Correct answer: B

Rationale: The correct word to use in this sentence is 'has' because 'One of the students' is singular, so it should be followed by a singular verb. The word 'has' is the correct singular form of the verb in this context. Choice A 'have' is plural, Choice C 'are' is also plural, and Choice D 'is' does not agree in number with the subject 'students'. Therefore, 'has' is the only correct choice here.

2. Select the word or phrase that makes this sentence grammatically correct. Before ________ this medicine, consume a modest meal.

Correct answer: B

Rationale: The correct form to use in this sentence is the present participle 'taking.' The sentence should read, 'Before taking this medicine, consume a modest meal.' It is important to use the present participle form when talking about an action that occurs before another action. Choice A 'having taken' is incorrect as it suggests a completed action before consuming a meal. Choice C 'took' is in the past tense, not suitable for indicating an action that should happen before another. Choice D 'will take' is in the future tense, which does not fit the context of the sentence.

3. Select the word that makes the following sentence grammatically correct: The centrifuge cannot run by ___________; it requires constant attention.

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.

4. Which of the following words fits best in the sentence below? ___________ she is the youngest member of her class, Octavia is taller than her classmates.

Correct answer: C

Rationale: The word 'Although' is the correct choice as it is used to introduce a contrast between two ideas. In this sentence, it highlights the unexpected nature of Octavia being taller than her classmates despite being the youngest member of her class. This conjunction effectively conveys the discrepancy between her age and height in the context of the sentence. Choice A ('Despite') indicates a contradiction or contrast but does not capture the nuance of unexpectedness present in the sentence. Choice B ('Since') implies a causal relationship, which is not the intended meaning. Choice D ('Provided') suggests a condition or stipulation, which is not suitable for the context of the sentence. Therefore, 'Although' is the most appropriate choice.

5. 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.

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.
