NURS 4526 Lecture Notes - Lecture 3: Diuresis, Chronic Kidney Disease, Polystyrene Sulfonate
Document Summary
Intracellular: located within cells accounts for 42% body wt. K is the main cation w/smaller amounts inside the cell of mg. Main anion is po4 with smaller amts of proteins & hco3. Extracellular: between cells (ie. interstitial & lymph) & plasma space 17% of body weight. Ca, mg. main anion is cl w/ amt of hco3, sulphage, po4. Transcellular space: (1l) ie. fluid in cerebrospinal space, gi tract, pleural space, synovial & peritoneal space. Of incr third spacing pleural effusion, pericardial effusion, hydrocephaly, fluid @ expense of fluid in other compartments. 1 l water = 1 kg (2. 2 lbs) For proper fluid balance, the distribution of fluid between the two compartments must remain relatively constant. Electrolytes are positively (cations) & negatively (anions) charged particles, make up body fluids, in different concentrations in the icf & ece. Sodium: normally present in high concentration in the ecf. Potassium: present in high concentration in the icf.
