Study Notes
Cellular and Fluid Imbalances
- Cellular swelling from diluted electrolytes can raise intracranial pressure, leading to brain damage.
- Edema is the accumulation of fluid in tissues, causing swelling and affecting organ function.
- Gastrointestinal distress includes symptoms like nausea, vomiting, and diarrhea from excessive fluid intake.
- Neurological effects from electrolyte imbalances can result in behavioral changes, disorientation, or lethargy.
- Excessive fluid intake can strain the kidneys, impairing fluid excretion and potentially causing kidney damage.
Key Clinical Signs
- Monitor for signs of swelling, distress, or changes in behavior and neurological function.
- Be alert for gastrointestinal symptoms linked to fluid imbalances.
Diagnostic Tests
- Serum Electrolyte Panel helps assess electrolyte levels.
- Blood Gas Analysis provides information on acid-base status.
- Complete Blood Count (CBC) gives insights into overall health.
- Urinalysis evaluates kidney function and fluid balance.
Acid-Base Balance
- pH is tightly controlled (7.35 to 7.45), essential for enzyme function and overall homeostasis.
- Enzyme activity is highly sensitive to pH fluctuations.
- Acid-base balance influences metabolic processes and can impact various organ systems.
Total Body Water (TBW) Distribution
- TBW constitutes approximately 60% of body weight, crucial for maintaining bodily fluid balance.
- Divided into Intracellular Fluid (ICF) - two-thirds within cells, and Extracellular Fluid (ECF) - all fluid outside cells.
- ECF includes interstitial and intravascular fluids (plasma volume).
Electrolyte Functions and Imbalances
- Electrolytes like sodium (Na+), potassium (K+), chloride (Cl-), and bicarbonate (HCO3) are vital for cellular functions.
- Hyponatremia refers to low sodium levels; hypernatremia indicates high sodium levels.
- Hypokalemia indicates low potassium levels; hyperkalemia reflects high potassium levels.
Importance of the Renin-Angiotensin-Aldosterone System (RAAS)
- Renin, released by kidneys in response to low blood pressure or sodium, activates RAAS.
- Aldosterone promotes sodium reabsorption and potassium excretion, maintaining electrolyte balance.
Potassium (K⁺) Roles
- Key cation for intracellular fluid (ICF), essential for nerve function and muscle contraction.
- Regulates heartbeat and aids in maintaining cellular fluid balance and osmotic equilibrium.
- Functions in the Na⁺/K⁺ pump, which preserves an electrochemical gradient critical for cellular function.
Monitoring and Management
- Maintain awareness of clinical signs associated with electrolyte and fluid imbalances.
- Regular diagnostic testing is crucial for timely detection and intervention.
