Institutional guidelines are pivotal for several reasons: 1. Consistency in Care: They ensure that all healthcare providers deliver care that is uniform and standardized. 2. Patient Safety: By following evidence-based practices, guidelines help in reducing medical errors and improving patient outcomes. 3. Legal Protection: Adhering to established guidelines protects nurses and healthcare institutions from legal liabilities. 4. Professional Development: Guidelines serve as a learning tool for new nurses and a reference point for seasoned professionals.
