Fluid & Electrolyte Nursing

💧 Fluid & Electrolyte Nursing

Fluid and electrolyte balance is essential for maintaining cellular function, hemodynamic stability, neuromuscular activity, and acid–base equilibrium. Even small imbalances in volume or key electrolytes such as sodium, potassium, calcium, and magnesium can lead to life-threatening cardiac, neurologic, or respiratory complications. Nurses play a central role in early detection through assessment of intake and output, daily weights, laboratory interpretation, and cardiac monitoring. Effective management requires integration of IV therapy, medication administration, dietary modification, and interdisciplinary collaboration to restore physiologic stability and prevent complications.
