Document Summary

Fluid regulation: body regulated fluid through , aldosterone, vasopressin/adh, normal gfr: 90-120, fluid balance in the body, pressures. In place for long periods: safe for vesicants, multiple lumens, very useful for rapid infusion or thick fluids (icu and critical care, cons, higher infection, bleeding, embolus risk, placed by trained infusion rn, can be uncomfortable. Electrolyte imbalance: major electrolytes, cations (+, sodium, potassium, calcium, magnesium, anions (-, chloride, phosphates, bicarbonate, extracellular, sodium, chloride. Hyperphosphatemia: decrease in renal excretion (kidney disease), hypoparathyroidism. Hypophosphatemia: etoh abuse, severe burns, severe malnutrition, decreased renal phosphate absorption, hyperparathyroidism, vit d deficiency, excessive diuretic use. Controls h20-imbalance impacts bp, neuro (icp & electrical conduction) Controls nerve impulses-imbalance impacts muscle function, cardiac function- overlaps with po4. (too dilute: mechanism of action for all diuretics: Increase calcium reabsorption: used for, diuresis, lower bp, remove excess fluid accumulation edema, meniere"s disease, nephrogenic diabetes insipidus more urine, thiazide diuretic works to decrease the volume, which decreases.
