Document Summary
Functions of the kidneys: produces urine, excretes waste products from metabolism (filters all blood in the body 180l per day, regulates fluid and electrolyte balance. Hyperkalemia is the most life threatening concern with a renal failure patient (effects rhythm of heart: regulates acid base balance. Kidney patients tend to have metabolic acidosis (because they are not buffering: water balance, bp control (renin angiotensin aldosterone system, renin produced by kidney, rbc production (erythropoietin) Patients with kidney problems are usually anemic: vitamin d to active form. Kidney patients cannot convert to active form (parathyroid effected: prostaglandin release. Dilation, renal blood flow: ca and po4, excretes bacterial toxins, water-soluble drugs and drug metabolites. Renin, angiotensin and aldosterone: renin is secreted in response to bp changes, angiotensin 1 goes to the lungs and becomes angiotensin 2, aldosterone is released in kidney fluid is held in the body bp increases. Electrolytes in = electrolytes out: glomerular filtration. Adult urine output = 1-2l/day: glomerular filtration rate.
