Correct Answer: B

Rationale: The subject 'The nursing staff' is a collective noun that is considered singular. Therefore, the correct verb form to use is 'hopes.' The verb 'hopes' agrees with the singular subject, making the sentence grammatically correct. Choice A ('hope') is incorrect because it is not the correct verb form for a singular subject. Choice C ('hoping') is incorrect as it is a gerund and does not function as the verb in this sentence. Choice D ('does hope') is incorrect as it introduces unnecessary emphasis and does not match the subject-verb agreement required in the sentence.

Correct Answer: A

Rationale: The correct punctuation needed in the sentence is a period. A period is used to indicate the end of a sentence. In this case, the sentence 'After you complete your rounds, please check in at the station.' is a complete thought and requires a period at the end to show that it is a complete sentence. The other choices are incorrect because a comma would not be suitable at the end of a sentence, a colon is used to introduce a list or an explanation, and a semicolon is used to connect two closely related independent clauses.

Correct Answer: C

Rationale: The correct punctuation needed in the sentence is a question mark. The sentence is a question, asking whether the lab results have been read in order to schedule an appointment. Therefore, a question mark is needed at the end of the sentence to indicate that it is an inquiry. The period is used for statements, not questions. A comma would not be appropriate here as the sentence is not a list or a compound sentence. An exclamation mark would imply excitement or surprise, which is not the tone of the sentence.

Correct Answer: C

Rationale: The correct option to substitute for 'Roseanne's' is 'her' to maintain correct pronoun-antecedent agreement. In this case, using 'her' makes the sentence grammatically correct and clear by referring back to Roseanne in a proper manner. Choice A, 'she,' is a subject pronoun and does not match the possessive form needed in the sentence. Choice B, 'their,' is plural and does not agree with the singular possessive 'Roseanne's.' Choice D, 'hers,' is a possessive pronoun but cannot directly replace 'Roseanne's' in this context; 'her' is the appropriate choice to indicate possession.

Correct Answer: C

Rationale: The correct spelling is 'embarrassing.' It is spelled with two consecutive r's and two consecutive s's. Option C is the only choice with the correct spelling. Options A, B, and D all have incorrect spellings. 'Embarrasing' (Option B) is missing an 'r,' and 'Emberassing' (Option D) has an extra 'e' and a missing 'r' and 's.' Therefore, the correct answer is Option C.
