Correct Answer: B

Rationale: The word 'unnecessary' is misspelled as 'unecessary' in the sentence. The correct spelling should have double 'n' as in 'unnecessary'. Choice A, C, and D are spelled correctly in the sentence provided.

Correct Answer: A

Rationale: The word 'her' is the correct choice because it serves as the object of the preposition 'at.' In this sentence, 'looked at' requires an object pronoun, making 'her' the appropriate choice. Option B, 'Hers,' indicates possession, which is not needed in this context. Options C and D are not pronouns and do not fit grammatically in the sentence.

Correct Answer: B

Rationale: The correct contraction for 'They are' is 'They're.' 'Their' is a possessive pronoun indicating ownership, not a contraction. 'The're' is not a valid contraction. 'No contraction used' is incorrect as there is a contraction for 'They are,' which is 'They're.'

Correct Answer: A

Rationale: The term 'fracture' refers to a 'break' in the bone. A fracture is a medical condition where there is a crack or break in a bone. 'Brake' refers to a device used to stop or slow down a vehicle. 'Cut' means to make an opening or incision with a sharp tool. 'Cure' means to relieve a person of the symptoms of a disease or condition.

Correct Answer: A

Rationale: The correct answer is A. "Do to" should be corrected to "due to" in this context. The sentence should read, "The client's hospital stay was prolonged, due to a superinfection." The phrase "due to" is the appropriate choice to indicate the cause of the prolonged hospital stay. Choices B, C, and D are all used correctly in the sentence and do not contain any errors.
