While regularization offers numerous benefits, it also presents several challenges: 1. Resistance to Change: Some nurses may resist adopting new practices, especially if they are accustomed to existing methods. 2. Resource Constraints: Implementing standardized practices may require additional resources, including time, money, and personnel. 3. Complexity of Healthcare: The dynamic and complex nature of healthcare can make it difficult to establish and maintain uniform practices. 4. Cultural Differences: Variations in cultural and organizational norms can impact the adoption of standardized practices.
