NURS 203 Chapter Notes - Chapter 3: Arteriolosclerosis, Kidney Stone Disease, Renal Pelvis
Document Summary
Example: pt has essential htn over 10 yrs, and pt is not compliant with medication kidney with cobblestone appearance = nephrosclerosis. Underlying dz causing it: hyaline arteriolosclerosis b/c there is decreased blood flow, tubular atrophy, glomeruli are fibrosing off, renal function is going down, and leads to renal failure. Example: lets say the pt wakes up with a big headache and blurry vision. Malignant htn (aka flea bitten kidney petechia visible on surface of kidney see vessel changes ie hyperplastic arteriolosclerosis, and the bv"s are rupturing, leading to petechial lesions on the cortex called flea bitten kidney). They can also ask rx: iv nitroprusside to get the bp down. So, they have cns edema with papilloedema, and if the bp isn"t lowered, they are gonna die. Irregular irregular pulse is from atrial fib, and atrial fib is most dangerous for embolization. So, these infarcts are from multiple emboli, leading to multiple pale infarcts of the kidney.
