Pockets are essential in nursing for several reasons: 1. Convenience: Pockets allow nurses to keep their hands free while still having easy access to tools. 2. Efficiency: Having immediate access to frequently used items can save time, which is crucial in a fast-paced healthcare setting. 3. Organization: Pockets help in keeping tools and supplies organized, reducing the risk of misplacing important items. 4. Preparedness: Being able to carry essential items at all times means nurses can respond quickly to patients' needs.
