The best estimate of functioning renal tissue is:
1) glomerular filtration rate (GFR)
2) hourly urine output
3) serum blood urea nitrogen and creatinine
4) the specific gravity of the solute concentration of the urine.
glomerular filtration rate (GFR)
An action of renin is the:
1) inactivation of autoregulation
2) direct activation of angiotensin II
3) direct release of ADH
4) activation of angiotensin I
activation of angiotensin I
When renin is released, it cleaves an a-globulin (angiotensinogen produced by liver
hepatocytes) in the plasma to form angiotensin I, which is physiologically inactive.
Which of the following is found in older adults?
1) A sharp decline in GFR and no change in renal blood flow
2) A sharp decline in renal blood flow and in GFR
3) A decrease in the number of nephrons
4) An increase in GFR leading to increased urine output
A decrease in the number of nephrons
The most common type of renal stone is comprised of:
1) magnesium-ammonium-phosphate
2) uric acid
3) calcium oxalate
4) magnesium phosphate
