Document Summary
If not filtering well- urine output decreases <400ml/day (urine concentrated). Water is retained leading to htn and edema. Waste products increase, bun increase, creatinine increases metabolic acisosis. Lytes imbalances (high k+, phosphate high, ca low) Primary functions of the kidneys: filter waste, maintain fluid and electrolyte and acid-base balance in the body. Secondary functions of the kidneys: to regulate bp renin (converts angiotensin 1 to angiotensin 2 in the case of low bp), bone density- calcium reabsorption, erythropoiesis (rbcs) Other functions: production of erythropoietin, activation of vitamin d, production, and secretion of renin. Age related considerations: decrease in size and weight of kidney from 30-90yrs. Decreased elasticity, weakening of bladder and urethra, decreased bladder capacity, prostatic enlargement. Past health history, medications, surgery, nutritional and elimination assessment, activity assessment, pain, self-concept and sexuality, coping assessment. Urine: urinalysis, general exam of the urine. Kidneys, ureters and bladder: shape, size and position of kidneys. Renal ultrasound: tissue density for cysts, masses and obstructions.
