HESI A2 Study Guide: Comprehensive Prep for Your Nursing Exam

Correct Answer: B

Rationale: The correct answer is B: "The nurse did not think that the symptoms warranted an emergency room visit." This sentence is grammatically correct because "warranted" is the appropriate verb to indicate that the symptoms did not justify an emergency room visit. Rationale: 1. "Warranted" means to justify or deserve. In this context, it correctly conveys that the symptoms did not merit an emergency room visit. 2. Option A uses "guaranteed," which implies a certainty that the symptoms will lead to an emergency room visit, not the intended meaning. 3. Option C uses "desired," which suggests that the symptoms wanted an emergency room visit, not the intended meaning of needing one. 4. Option D uses "should have been," which is grammatically incorrect in this context and does not convey the intended meaning of justification for an emergency room visit. In summary, option B is the correct choice as it effectively communicates that the symptoms did not justify an emergency room visit,

Correct Answer: A

Rationale: Choice A is correct as it uses 'snake' as a verb, indicating the action of moving in a winding or stealthy manner. In contrast, Choices B, C, and D use 'snake' as a noun in different contexts: Choice B as an adjective, Choice C as a tool, and Choice D as a descriptive term for a reptile. Therefore, only Choice A fits the criteria of using 'snake' as a verb.

Correct Answer: C

Rationale: The correct answer is C. 'Envelopes' is the correct term to refer to multiple items without implying possession. Using 'envelope's' implies ownership, which is not the intended meaning in this context. Therefore, 'envelopes' is the correct word to use in this sentence to indicate that the mail carrier puts multiple envelopes in each mailbox on the block.

Correct Answer: D

Rationale: The correct answer is D, 'himself.' In this sentence, 'himself' is the reflexive pronoun that correctly completes the sentence. Reflexive pronouns like 'himself' are used when the subject and object of a sentence refer to the same person or thing. Therefore, the sentence should be: 'The student was very proud of himself when he aced the test.'

Correct Answer: D

Rationale: The correct answer is D. It should be 'was' instead of 'were,' as 'procedure' is singular. When referring to a singular noun like 'procedure,' the verb should also be singular. In this case, the correct verb form is 'was' to match the singular noun 'procedure.' Therefore, the sentence should read, 'The procedure for giving injections was explained thoroughly to the student nurses.'
