What is the dominant cation in ICF? Potassium
What regulates ICF? Potassium
What facilitates contraction of skeletal and smooth muscles, including myocaridal contraction...(regulates heart rhythm) Potassium
Assists with nerve impulse conduction Potassium
Assists with acid base balance Potassium
Hypokalemia causes Potassium of <3.5, overuse of diuretics, vomiting and diarrhea, overuse of laxatives, ASA, Amphotericin B, Kayexlate
Hyperkalemia >5.0 Adrenal insuf. Increased K in diet, Antineoplastic medications, INH, Heparin, over use of K supp., K sparing diurectics, Renal Failure
What are the 5 interventions for Hypokalemia 1.High K diet 2.Administer IV or po K 3.Monitor I&O, 4.EKG 5.labwork
What are the 5 interventions for Hyperkalemia 1.Omit food that contain K 2.Kayexlate (PO,NG,ENEMA) 3.Monitor I&O 4.EKG 5.Labs
Normal levels of Calcium 8.4-10 mEq/L
4 Functions of Calcium 1.plays a role in cell permeability 2.formation of bones and teeth 3.blood coagulation 4.transmission of nerve impulses and normal muscle contraction
5 causes of Hypocalcemia <8.4 1.duetart deficiency 2.pancreatic dz 3. dz of the small bowel 4.decreased function of the parathyroid 5.decrease in vit D
5 causes of Hypercalcemia >10 1.Metastatic bone ca 2.excessive intake of ca 3. increased function of the parathyroid 4.excessive vit d 5. antacids containing ca
3 functions of MG 1.regulates skeletal 2. stimulates parathyroid homone, thus regulates ICF CA++ lvels 3. second most abundnat IC cation
Normal range of MG 1.3-2.1mEQ/L
4 causes of Hypomagnesemia <1.3 1.chronic alcoholism 2.chronic diarrhea 3.prolonged nasogastric sx 4.starvation
3 causes hypermagnesemia >2.1 1.Kidney's inability to excrete MG++ that was wither absorbed from the intestine or infused 2.chronic renal failure 3. overdose of MG++
Normal range of Na+ 135-145 mEq/L
3 functions of Sodium 1. controls distribution of water throughout the body 2.regulates ECF volume 3.plays important role in the transmission of nerve impulses and muscular contraction
6 causes of hyponatremia <135 1.vomiting 2.diarrhea 3.NG tube sx 4. Excessive sweating 5.Nutritional deficit 6. Potent diuretics
7 causes of Hypernatremia > 145 >145 1. more H20 than Na+ from the body 2.excessive intake of Na+ 3. corticosteroids 4. excessive use of laxatives 5. anti-inflammatory drugs 6. oral contraceptives 7. iv saline infused rapidly
