extracellular buffering
respiratory regulation
renal regulation
H+ secretion for body fluid acidity regulation is
passive
active
If urine pH becomes less than (a) , H+ secretion stops
Increased aldosterone leads to
(a)
increased dietary intake of K+ leads to
increased K+ secretion
decreased K+ secretion
Increased renin leads to an increase in AT2, causing vasoconstriction of the ___ arteriole, therefore ____ GFR
affarent
efferent
increasing
decreasing
AT2 causes a(n)
Increase in Na+/H2O reabsorption in the PT
Decrease in Na+/H2O reabsorption in the PT
Increase in aldosterone production
Decrease in aldosterone production
ANP causes a(n)
increase in Na+/H2O reabsorption
decrease in Na+/H2O reabsorption
vasodilator effect (decreasing BP)
vasoconstriction effect (increasing BP)
ADH promotes
Na+ and H2O retention
Na+ retention only
H2O retention only
___ is the gold standard for measuring GFR?
SCr
CrCl
Inulin
BUN
BUN:SCr
BUN:SCr ratio is used as a guide when assessing cause of renal insufficiency. BUN:SCr < 20 suggests
postrenal
prerenal cause
Intrinsic/renal cause ONLY if SCr is elevated
Intrinsic/renal cause ONLY if SCr is decreased
BUN:SCr ratio is used as a guide when assessing cause of renal insufficiency. BUN:SCr > 20 suggests
postrenal
prerenal cause
Intrinsic/renal cause ONLY if SCr is elevated
Intrinsic/renal cause ONLY if SCr is decreased
The FENa EQ tells how much Na+ is reabsorbed in the kidney as a percentage. A FENa > 100% would represent

no renal disease
Granular casts indicates
ischemic renal damage or toxic insults
intrinsic renal disease
no renal disease
