| Question | Answer |
|---|---|
| Electrolytes | regulate H2O distribution, neoromuscular activity and neuromuscular excitability |
| Kidneys | Filter plasma and excrete urine |
| Heart | carries nutrients and H2O in body |
| Lungs | O2 and Carbon Dixide levels |
| Adrenal glands | concerve Na, save chloride and water, excrete K |
| Thyroid gland | increases blood flow and renal circulation |
| Parathyroid surgery can | cause injury that upsets Ca+ level because parathyroid regulates Ca+ |
| With all electrolytes, if you can't excrete | you will have hyper(whatever) |
| Na+ | Helps nerve and muscle cells interact, controls and regulates volume of body fluids |
| Na+ and water | stick together |
| Normal Na+ | 135-145 |
| Hypernatremia | above 145 |
| Hyponatremia | below 135 |
| Hyponatremia can occur with | too little sodium, overhydration, rapid IV infusion, |
| Hyponatremia can occur with cont. | loss of fluid from vomiting, GI suctioning, adrenal gland deficency, excessive sweating |
| Hyponatremia s/s | letheragy, confusion, leg cramps, decreased urine specific gravity below 1.010 |
| Tx of Hyponatremia | give Na+ IV, sodium in diet, in desert ppl take Na+ tab., Corrent underlying problem |
| Hypernatremia causes | to much sodium, dehydration, profuse sweating |
| Hypernatremia s/s | thirst, elevated temp, dry tongue |
| If pt. is hypertensive they need | low sodium diet |
| Temp maybe elevated | due to elevated fluid |
| Potassium | 3.5-5 |
| There is to be no deviation is K | to much or too little can cause cardiac problems |
| Need K to | control nerve impulses, cell excitability and muscle contraction (cardiac) |
| To administer K you must | check K levels, to high can cause cardiac arrect |
| K should be given in a | diluted solution |
| NEVER give K | IV push or syringe |
| Causes of Hypokalimia | vomiting, diarreha |
| Medications for Hypokaliuma | diaretics, K-Dur, Kchlor, Florcimide |
| Diet to control Hypokalumia | Bannanna, peaches, dairy, broccili, meats |
| Hypokalumia s/s | leg cramps, weak and fatigue |
| Hypokalumia can lead to | cardiac Arrhythmia and EKG changes |
| Causes of Hyperkalumia | increase intake, decrease excrete (/c kidney problems renal problems, elderly) |
