Final answer:
The best response for a charge nurse to a CNA's concern regarding the care of incontinent clients is to discuss the workflow organization to ensure fair task distribution.
Step-by-step explanation:
When a CNA expresses concerns about the fairness of their workload, specifically regarding the care of clients who are incontinent, it is important for the charge nurse to address the concern in a professional and supportive manner. Option C: "Let's talk about organizing workflow so you care for fewer of these clients" would be the most appropriate response. This answer acknowledges the CNA's concern and suggests a collaborative approach to problem-solving, which can help ensure a proportional distribution of tasks and maintain a positive work environment.
