Study Notes
Electrolytes and Body Fluids
- Electrolytes are charged ions in body fluids.
- Cations are positive ions, and anions are negative ions.
- Electrolytes are distributed between intracellular (ICF) and extracellular (ECF) fluids.
- ICF and ECF have different electrolyte concentrations.
- This difference is crucial for nerve impulse transmission and cell excitability.
- Body fluids must be electrically neutral (equal positive and negative ions).
- Electrolytes conduct electrical current (positive: cations, negative: anions).
- Examples of cations: magnesium, potassium, sodium, calcium, and hydrogen ions.
- Examples of anions: phosphate, sulfate, chloride, bicarbonate, and proteinate ions.
Electrolyte Imbalance
- Electrolyte imbalance can occur due to intake and output imbalances.
- Illnesses and aging increase the risk of electrolyte imbalance.
- Plasma electrolyte concentrations can be measured, but intracellular levels cannot.
Expected Reference Ranges (in Plasma)
- Sodium: 136–145 mEq/L
- Calcium: 9.0–10.5 mg/dL
- Potassium: 3.5–5.0 mEq/L
- Magnesium: 1.3–2.1 mEq/L
- Chloride: 98–106 mEq/L
- Phosphorus: 3.0–4.5 mg/dL
Sodium Imbalance
- Sodium (Na+) is the major ECF cation, maintaining ECF osmolarity.
- ICF sodium is low (approximately 14 mEq/L).
- The sodium gradient between ICF and ECF is vital for muscle contraction and nerve impulse transmission.
- Sodium concentration influences fluid movement and retention.
- Kidney function regulates sodium levels via hormones like aldosterone, ADH, and natriuretic peptide.
