Question | Answer |
---|---|
Function r/t Kidneys | Urine formation, Excretion of waste, Acid-base regulation, Water balance, BP control |
Renal replacement therapy indication r/t Nephrons | Total functioning nephrons < 20% normal |
Juncitons of ureters have propensity for obstruction by | Renal calculi |
Allows continentence to be maintained | External urinary sphincter |
Antidiuretic hormone synonym | Vasopressin |
ADH is secreted by | Posterior portion of Pituitary gland(PPP) |
Early sign of kidney disease r/t Urine specific gravity | Fixed specific gravity indicates inability to concentrate and dilute urine |
Normal serum Na level | 135-145 |
Na is only cation that exerts significant osmotic pressure, thus it is linked to | Blood volume and BP |
Aldosterone function | Regulates Na volume |
Increased aldosterone r/t Na excretion | Less Na is excreted, Aldosterone conserves Na and Water |
Aldosterone r/t K excretion | Aldosterone causes K excretion |
Most life-threatening effect of renal failure | K Retention |
Bicarbonate r/t Kidney function | Kidney reabsorbs and returns to circulation |
Creatinine clearance r/t Glomerular filtration rate(GFR) | CC decreases as renal function decreases |
Strong desire to void r/t 350 mL or more of urine | "Functional capacity" |
GFR r/t Aging | GFR decreases |
Tenderness location r/t Kidneys | Costobertebral Angle(CVA) tenderness |
Urine leakage during Valsalva maneuver & Marshall-Boney maneuver | Refer to MD |
Urine specific gravity r/t Fluid intake | Inverse relationship, Fluid intake increases so Urine specific gravity decreases |
Pt Care during Urologic testing w/Contrast agents | Have emergency equipment available, Know Pt allergy to iodine |
Examples r/t Tests that use contrast agents | MRI, IV Urography, Retrograde pyelography, Cystography, Voiding Cystourethrography, Renal angiography |
Pt restrictions r/t Cystoscopy | NPO for several hours before |
