The nurse realizes that the nursing assistant needs further teaching if she observes the nursing assistant: A. Walking the postoperative client with leg pain B. Bathing the client using soap and water C. Changing the bed of the client in traction from top to bottom D. Feeding the client using a disposable spoon and fork

Begin by analyzing each of the given options in regards to acceptable patient care practices. A. Walking the postoperative client with leg pain: This action can be considered appropriate as it is essential for postoperative patients to promote blood circulation and avoid complications. However, it is also essential to monitor the pain level. B. Bathing the client using soap and water: This is a standard and appropriate practice, as maintaining proper hygiene is essential for clients. C. Changing the bed of the client in traction from top to bottom: This seems inappropriate regarding patients in traction, as it may cause complications or exacerbate existing issues. Proper handling and care are necessary for patients in traction, such as using draw sheets and asking for assistance. D. Feeding the client using a disposable spoon and fork: This is a sanitary approach and acceptable for feeding clients.

Based on the analysis in Step 1, we can conclude that option C (Changing the bed of the client in traction from top to bottom) is the action that indicates the nursing assistant needs further training and understanding of proper patient care for patients in traction. Therefore, the correct answer is C.
