Electrolyte function and normal levels Flashcards
Normal level: 136-145 mEq/L
-principal ion responsible for resting membrane potential of cells
-essential in depolarization needed for nerve and muscle contraction
-principal cation of the ECF
-Na-K pump essential for producing body heat
Sodium (Na)
Normal level: 3.5-5mEq/L
-produces resting membrane potentials and action potentials of nerve and muscle cells
-principal cation of the ICF and responsible for intracellular osmolarity
-essential component of Na-K pump and involved in protein synthesis
Potassium
Normal level: 9-10.5mEq/L
-primary component of bones and teeth
-plays role in blood clotting
-nerve impulse transmission
-cardiac conduction
-muscle contraction
Calcium
Normal level: 1.5-2.5 mEq/L
-found inside cells
-key role in production and use of ATP
-helps regulate intracellular metabolism by activation of enzymes
-required for synthesis of nucleic acids and proteins
-helps maintain normal serum and calcium levels
Magnesium
Normal level: 98-106 mEq/L
-most abundant ion in the ECF
-maintains serum osmolarity
-required for formation of stomach hydrochloric acid
-buffering role in acid-base balance
Chloride
Normal level: 3-4.5mEq/L
-most abundant ion in ICF\
-helps maintain bone and teeth structure
-role in cellular metabolism and ATP production
-essential for carbohydrate metabolism
