AHN 447 EXAM 1 (RENAL) QUESTIONS
AND ANSWERS 2026 VERIFIED.
- fluid & electrolyte balance/acid-base balance
- rid the body of water soluble waste products
- maintain normal blood volume and osmolarity
- production of erythropoietin
- activation of vitamin D to facilitate absorption of calcium - ANS What are the functions
of the renal system?
- filtration of water soluble substances
- reabsorption of filtered nutrients, water, and electrolytes
- secretion of waste products - ANS What are the 3 major function of the nephron?
glomerulus - ANS prevents transport of bleed cells and proteins; more permeable than
other capillaries in the body
blood volume - ANS What is one of the most important factors of GFR?
renin - ANS formed and release when there is decreased blood flow, volume, or pressure
1
, angiotensin I and angiotensin II - ANS What does renin stimulate the production of?
angiotensin II - ANS causes vasoconstriction and the release of aldosterone
aldosterone - ANS increases the reabsorption of Na++
prostaglandins - ANS produced in the kidney and regulates GFR, renal vascular resistance,
and renin production
bradykinin - ANS dilates renal vasculature to maintain renal blood flow - released after
Angiotensin II
erythropoietin - ANS triggers RBC formation in marrow
vitamin D - ANS converted to active form in the kidney
0.6-1.2 mg/dl - ANS What is the normal value of creatinine?
serum creatinine; no other pathologic condition other than renal disease increases the serum
Creatinine level - ANS What is the best indication of renal failure and why?
10-20 mg/dl - ANS What is the normal value for BUN?
BUN - ANS indirect measure of overall hydration
