Antidiuretic Hormone is secreted by ____ in response to ____? the posterior pituitary; serum hyperosmolality and low blood volume
Aldosteone is secreted within the renin-angiotensin system after? stimulation by angiotension II
Kidney postaglandins lower BP by? causing vasodilation
Erythropoietin is released when? the oxygen tension of the renal blood supply is low
Erythropoietin stimulates the production of? RBC in the bone marrow
Hyperkalemia stimulates the release of? aldosterone from the adrenal cortex

Position of pt. during kidney examination? supine
Urinalysis of urine specimen not processed within 1 hr. may result in erroneous measurements of? bacteria; they multiple rapidly in warm urine

Urinalysis result of UTI may include? cloudy, yellow, wbc > 5/HPF, pH 8.2, numerous casts
Urinary casts are? cylindrical structures produced by the kidney and present in the urine in certain disease states
Specific gravity measures? the kidney's ability to concentrate or dilute urine in relation to plasma

The Glomerulus Filtration Rate (GFR) approximates? the rate at which creatinine is cleared from the blood and eliminated in urine
The most specific test of renal function is the? Glomerulus Filtration Rate (GFR)
The size, shape and general blood perfusion can be diagnosed with which exam? renal scan
Impaired conversion of inactive VitD to active VitD results in? hypocalcemia
