Fluid, Electrolytes, and Acid-Base Balance
The provided sources offer a comprehensive overview of fluid, electrolyte, and acid-base balance within the human body, emphasizing the nurse's role in assessment and intervention. They explain the physiological functions of major electrolytes (sodium, potassium, calcium, and magnesium) and detail the signs, causes, and treatments for various imbalances like dehydration, hypovolemia, and hypervolemia. Crucially, the texts cover intravenous therapy, outlining the types of solutions (isotonic, hypotonic, hypertonic crystalloids, and colloids), venous access devices (peripheral and central lines), and procedures for safe administration, including blood product transfusions with stringent safety protocols. Finally, the sources explain acid-base imbalances (respiratory and metabolic acidosis and alkalosis), how to interpret arterial blood gas (ABG) values, and the corresponding compensatory mechanisms and treatments.
