Goal: Discuss the principles of glomerular filtration and renal hemodynamics and provide nephrology nurses with the ability to predict, identify and assist in the treatment of clinical conditions that can alter glomerular filtration and renal hemodynamics.
Discuss the intrinsic and extrinsic factors that can alter renal hemodynamics.
Describe the renin-angiotensin mechanism and its role when renal ischemia occurs.
Explain the multiple integrated factors that work in concert to maintain a consistent renal blood flow and glomerular filtration despite systemic pressure changes.
