HESI A2 Grammar Practice Test

Correct Answer: D

Rationale: The correct answer is D, "standing with the refrigerator door open." This phrase is misplaced because it should directly follow "open carton of orange juice" to properly describe where it was located. Placing it at the end of the sentence disrupts the flow and creates confusion. The other choices (A, B, C) are in the correct order and contribute to the clarity and coherence of the sentence.

Correct Answer: C

Rationale: The correct answer is C: datum. In the sentence, "datum" is used incorrectly as it should be "data" to maintain subject-verb agreement. "Data" is the plural form of "datum." The word "personal" and "vital" are used correctly as adjectives describing the type of data being collected. "Roles" is also used correctly as a noun describing the duties of an intake nurse. Therefore, the incorrect usage of "datum" makes option C the correct answer.

Correct Answer: A

Rationale: The correct answer is A: oneself. In the sentence, "one" is a singular pronoun, so the reflexive pronoun that follows should also be singular. "Oneself" is the appropriate reflexive pronoun for the singular pronoun "one." Choices B and C are incorrect as "oneselves" is not a correct reflexive pronoun form, and "hisself" is not a standard English term. Choice D, "themselves," is incorrect because it is a plural reflexive pronoun, and it does not agree in number with the singular pronoun "one" in the sentence.

Correct Answer: B

Rationale: The correct answer is B: quickly. In the sentence, "quickly" is used as an adverb to modify the verb "calculate." However, the word "quickly" should be used to describe how an action is done, not the action itself. The verb "calculate" should be modified by an adverb that describes the manner of the calculation, such as "accurately" or "carefully." The other choices (A: calculate, C: possibly, D: right) are all used correctly in the sentence.

Correct Answer: B

Rationale: The correct answer is B: Comma. The sentence "Follow my lead, I have been performing this procedure for years" is a compound sentence with two independent clauses. A comma is needed before the conjunction "I" to separate the two independent clauses correctly. Using a period (A) would create two separate sentences. Using an exclamation point (C) would be inappropriate as the sentence is not expressing strong emotion. A semicolon (D) could be used, but a comma is more commonly used to connect two closely related independent clauses.
