NUR 339 Electrolytes
- electrolytes
positive or negative charge in water regulate chemical reactions regulate muscle contractions maintain fluid balance
- sodium
135-145
- chloride
97-107
- calcium
8.8-10.4
9-10.5
majority in bones
- potassium
3.5-5.0
- magnesium
1.8-2.6
1.3-2.1
- phosphorus 1 / 2
Answer
2.7-4.5
3-4.5 stored in bones and teeth
- faster and greater imbalance of electrolyte occurs
the more symptomatic the pt will be
- sodium
most abundant electrolyte in ECF 135-145
-primarily determinant of fluid volume balance -binds with CL to form salt (where salt goes water goes) contributes to muscle contraction and nerve impulse transmission
red by
antidiuretic hormone, thirst, renin angiotensin aldosterone system
- hyponatremia
< 135 Na levels acute
commonly seen in postop pts from iv fluids -sodium level low die to increase fluid in vascular space (dilutional)
chronic
seen in pts outside of hospital -longer duration and less neurological manifestations
-exercise related
