Correct Answer: C

Rationale: The correct action for the nurse to take in this situation is to inform the surgeon that the operative permit is not signed and that the client has questions about the surgery. It is the responsibility of the surgeon to explain the procedure to the client and obtain the client's signature on the permit. While the nurse can witness the client's signature on the permit, the procedure must first be explained by the healthcare provider or surgeon, including addressing the client's questions. Therefore, informing the surgeon is the priority to ensure proper communication and consent before the surgery. Answering the client's questions about the surgery (Choice B) may not provide accurate information and could lead to misunderstanding. Reassuring the client (Choice D) is important, but obtaining proper consent and addressing concerns should come first. Witnessing the client's signature (Choice A) is not sufficient if the client has unanswered questions and the permit is not signed.

Correct Answer: B

Rationale: The most important instruction for the nurse to provide to the client is to change positions in the chair at least every hour. This is crucial to prevent pressure ulcers, as prolonged pressure on the skin can lead to tissue damage. Repositioning helps relieve pressure on vulnerable areas like the sacrum. Increasing fluid intake can also aid in preventing skin breakdown by maintaining skin hydration. While a vitamin supplement may support overall health, it is not as critical as repositioning to prevent pressure ulcers. Purchasing a new wheelchair is an expensive intervention and should be considered a last resort after implementing less costly preventive measures.

Correct Answer: A

Rationale: When the nurse rolls contaminated gloves inside-out, they are manipulating the mode of transmission in the chain of infection. The gloves, which are contaminated, act as a vehicle for transferring pathogens from the reservoir's portal of exit to a potential portal of entry. Choices B, C, and D are incorrect because the action of rolling contaminated gloves does not directly relate to the portal of entry, reservoir, or portal of exit in the chain of infection.

Correct Answer: C

Rationale: The correct answer is 'Cranberry juice stops pathogens' adherence to the bladder.' Cranberry juice maintains urinary tract health by reducing the adherence of Escherichia coli bacteria to cells within the bladder. This helps prevent UTIs. Options A, B, and D are incorrect because orange juice with vitamin C, apple juice for urine acidification, and grapefruit juice for antibiotic absorption do not have the same proven effectiveness in preventing UTIs as cranberry juice does.

Correct Answer: D

Rationale: The best nursing action is to review the schedule of outdoor breaks and provide concrete information about the schedule. Suggesting a nicotine patch (Option A) is not suitable as the client wants to smoke. Reassuring the client about another break (Option B) does not address the client's frustration and does not promote effective communication. Having the client leave the unit with another staff member (Option C) is not appropriate as it goes against unit rules and does not address the client's concerns. Therefore, the most appropriate intervention is to review the schedule of outdoor breaks with the client to provide clarity and address the client's frustration effectively.
