Fluids and Electrolytes
The Fluids and Electrolytes course provides healthcare professionals with a practical understanding of fluid balance, electrolyte regulation, and acid-base homeostasis. Learners will explore body fluid compartments, kidney function, and common fluid and electrolyte disorders while developing the knowledge to assess and manage these conditions safely in clinical practice.

Learning Outcomes
What you'll learn
- Explain the structure of body fluid compartments and the movement of fluids between intracellular and extracellular spaces.
- Describe the fundamental chemical concepts, including electrolytes, osmosis, tonicity, pH, and their significance in human physiology.
- Identify the distribution and function of major body fluids and electrolytes under normal physiological conditions.
- Explain the mechanisms that regulate fluid balance, including the roles of the kidneys, antidiuretic hormone (ADH), and aldosterone.
- Recognize the physiological changes associated with common fluid and electrolyte disorders and their underlying causes.
- Describe the regulation of key electrolytes, including sodium, potassium, calcium, and phosphate, and their impact on normal body function.
- Interpret the principles of acid-base balance, buffering systems, and the body's respiratory and renal compensatory mechanisms.
- Differentiate between common electrolyte and acid-base abnormalities, including hyponatremia, hypernatremia, hypokalemia, hyperkalemia, metabolic acidosis, and metabolic alkalosis.
- Assess clinical scenarios involving dehydration, edema, volume overload, and electrolyte disturbances using evidence-based principles.
- Apply appropriate fluid therapy and electrolyte replacement strategies to support safe and effective patient management in clinical practice.
