Final answer:
To implement quality improvement, both Nurses and Hospital Administrators must be able to identify issues, develop and act on a plan, and evaluate the results, hence the answer is d) All of the above.
Step-by-step explanation:
To implement quality improvement based on knowledge, the Nurse and Hospital Administration must be able to: 
- Identify the issues and problems - This involves recognizing critical problems and barriers to health care quality.
 - Develop and implement a plan of action - This entails designing sustainable health education and disease prevention interventions that lead to better health outcomes.
 - Evaluate the results - After implementing the plan, it's crucial to assess its effectiveness to ensure continuous improvement. 
 
Therefore, the correct answer is d) All of the above. 
In the context of a medical setting, doctors usually have more authority, but nurses are crucial in the implementation and monitoring of care quality improvements. The relationship between doctors and nurses can significantly impact how a proposed solution—like a checklist—is adopted and utilized. A checklist can be both a simple and complex solution, as the creation process can be straightforward, but ensuring effective use in practice often involves complex changes to behavior and processes within the healthcare system.
