HESI A2 Grammar Practice Test

Correct Answer: C

Rationale: The correct answer is C: Embarrassing. The correct spelling follows the pattern of the word "embarrass," with a double "r" and double "s." Double consonants are necessary to maintain the short vowel sound in the middle syllable. Choice A is correct as it follows this pattern. Choice B misspells the word by omitting an "r." Choice D misspells the word by substituting "r" with "m" and "s" with "n."

Correct Answer: B

Rationale: The correct answer is B: raised their hands to ask questions. In the sentence, "When the lecture was over, two students" is in past tense, so the verb should also be in the past tense to maintain grammatical consistency. "Raised" is the past tense form of "raise," making it the appropriate choice. Choices A, C, and D are incorrect because they use present or present perfect verb forms, which do not match the past tense context of the sentence.

Correct Answer: B

Rationale: The correct answer is B: prescription. In the given sentence, the word "prescription" is spelled correctly. The term refers to a written instruction from a medical practitioner for the preparation and administration of a drug or treatment. The other choices, pharmacist, designated, and physician, are also spelled correctly and are relevant to the context of the sentence. Therefore, the word "prescription" is the correct answer as it is not misspelled in the sentence.

Correct Answer: C

Rationale: The correct answer is C: "to be". In the sentence, "to be" is not used correctly because the phrase should be "to be on his own" instead of just "to be". The infinitive form "to be" should be followed by the prepositional phrase "on his own" to convey the intended meaning of being alone. The other choices A, B, and D are all used correctly in the sentence and do not impact the clarity or correctness of the statement.

Correct Answer: C

Rationale: The correct answer is C: study. In the sentence, "study" should be "studies" to match the singular subject Sidney. The verb should agree with the subject in number, so it should be "Sidney studies for the exam." A: "practices" is correct as it agrees with the subject Jack. B: "while" is used correctly as a conjunction to show simultaneous actions. D: "exam" is used correctly as the object of the preposition "for."
