Regulation & Function of Electrolytes Flashcards
(38 cards)
2\3 of body fluid
Intracellular Fluid (ICF)
95-105 mEq/L
Chloride (Cl)
1.5-2.5mEq/L
Mg
2.5-4.5m/dL
PO4
135-145 mEq/L
Sodium (Na)
3.5-5.3 mEq/L
Potassium (K)
4.25-5.25 mg/dL (serum)
Calcium (Ca)
9-11 mg/dL (ionized)
Calcium (Ca)
- Cheif electrolyte of ECF
- Maintains water balance
- Transmits nerve impulse and promotes muscle contraction
Sodium Na
Electrolyte Function
- Regulates ECF Volume & Distribution
- Maintains Blood Volume
- Transmitting Nerve impulses & contracting muscles
Sodium (Na+)
- essential for functioning of muscles, nerves, & red blood cells
- involved in the metabolism of protein, fat, & carbahydrate
Phosphate (PO4)
- Found in ICF, heart, bone, nerve, & muscle tissues
- 2nd most important anion in ICF
Mg
Major anion of ECF & normal saline.
Functions with Na to regulate serum osmolarity & blood volume
Chloride
Major component of gastric juice, HCO3 ,
Chloride
- Major anion of intracelluar fluids (ICF)
- found in ECF, bone, skeletal muscles, and nerve tissue
Phosphate PO4
Electrolyte Regulation
- Renal reabsorption or excretion
- Aldosterone increases Na reabsorption in collecting duct of nephrons
Sodium (Na+ )
- Renal excretion & conservation
- _________ increases K excretion
Aldosterone
(potassium)
- Helps maintain electrical activity in nervous & muscle tissue
Magnesium
HCO3
Major body buffer involoved in acid-base regulation
Osomosis
movement of water across a cell membrane, from the least concentration to higher in attempt to equalize
osmolality
expression of concentrations of soultes
isotonic solutions
equal to concentration as body fluids
- 0.9% NaCl
- Lactate Ringer
- D5W
Isotonic Solutions
Hypertonicm Solutions
higher osmolality than body fluids
