Study Notes
Electrolyte Imbalances
- Dehydration leads to increased osmolality affecting intracellular phosphate levels.
- Low sodium (Na) intake or loss results in symptoms such as thirst and weight gain.
- Increased blood pressure (BP) and cerebral edema are common in dehydration.
- Hyperactive reflexes and bounding pulse coupled with confusion can indicate severe electrolyte fluctuations.
Potassium (K) Levels
- Normal potassium levels range from 3.7 to 5.0 mmol/L.
- Skeletal muscle weakness and neuromuscular excitability decrease in cases of hypokalemia.
- Hyperkalemia, characterized by rare renal excretion, can lead to muscle weakness, nausea, and impaired renal function.
Calcium (Ca²⁺) Levels
- Normal calcium levels range from 8.4 to 10.6 mg/dL.
- Low parathyroid hormone (PTH) and vitamin D can lead to hypocalcemia, increasing neuromuscular excitability.
- Symptoms of hypocalcemia include fatigue, spasms, cramping, tingling, and potential cardiac issues.
Fluid Accumulation
- Localized or generalized edema may occur due to increased capillary permeability, infections, or injuries.
- Conditions causing edema include heart failure and kidney disease affecting fluid retention and distribution.
Respiratory Regulation of pH
- Conditions like COPD and pneumonia can lead to respiratory acidosis, indicated by a pH less than 7.35.
- In respiratory alkalosis, the pH is greater than 7.45, affecting the body's acid-base balance.
- Increased ventilation helps remove CO2 thus correcting low pH by reducing acidity.
Urine pH Regulation
- Urine acidity or alkalinity is controlled through the secretion of H⁺ or reabsorption of bicarbonate.
- Acidic urine leads to the excretion of H⁺ ions, while alkaline urine involves the retention of CO2 to increase acid levels.
