Document Summary
What do kidneys do: balance water and electrolytes, regulate production of red blood cells, aid in calcium absorption, maintain blood volume, composition, ph, play a role in regulating blood pressure via renin aniogension system. Renal development and function in infancy: development of the kidney begins in the first weeks of embryonic life and is completed around 1 year, nephrons increase in number throughout gestation and reach full complement by birth at term. -> at birth tubular sections incompletely formed and glomeruli small/less convoluted and therefore have a smaller surface area (makes absorption and excretion difficult) Newborn retains more nitrogen and electrolytes for rapid growth. Factors affecting water balance: water lost through, excretion of urine, excrtion of feces, vomiting/diarrhea, fever, birns, shock, increased icp, post-op conditions, congestive heart failure, renal failure. Renal system assessment: urinalysis, overall appearance: color/physical assessment, vital signs, behavior, weight.
