Sample Glomerular Filtration Rate, Renal Blood Flow, and Renal Clearance MCQs with answers
Sample MCQ #1
Which of the following glycoprotein is found in glomerular basement membrane?
AChondroitin sulfate
BKeratan sulfate I
CHeparan sulfate
DKeratan sulfate II
Show Answer & Explanation ▾
✓ Correct Answer: C. Heparan sulfate
GBM consists mainly of: Collagen (mostly type IV) Laminin Polyanionic proteoglycans (heparan sulfate) - repels protein albumin Reference: Ganong, 25th edition page no.677
Sample MCQ #2
Two particles have same diameter. The one which will pass easily through glomerular membrane has
APositive charge
BNegative charge
CAny of the above
DCharge has no relation
Show Answer & Explanation ▾
✓ Correct Answer: A. Positive charge
Positively charged molecules are filtered more readily than negatively charged molecules Reference: Ganong, 25th edition page no.677
Sample MCQ #3
All should be features of a substance to measure GFR, except
AFreely reabsorbed
BFreely filtered across glomerulus membrane
CNot secreted by kidney
DNone
Show Answer & Explanation ▾
✓ Correct Answer: A. Freely reabsorbed
Criteria of a substance to be used in estimation of GFR The substance is freely filtered by the glomeruli and neither reabsorbed nor secreted by the tubules It is biologically inert and non-toxic It is neither metabolized nor stored in the kidneys Its concentration can be easily estimated in the laboratory Reference: Ganong, 25th edition page no.677
Sample MCQ #4
To reduce the hemolysis that occurs with dialysis, researchers have developed an organic filtration membrane for dialysis that is believed to mimic the physiologic filtering apparatus of the human glomerulus. The permeability characteristics of this membrane are believed to be identical to those of the glomerular filtering membrane Which of the following substances should be absent in the filtrate produced by this membrane?
ASodium
BCreatinine
CAmino acids
DAlbumin
Show Answer & Explanation ▾
✓ Correct Answer: D. Albumin
Glomerular basement membrane selectively filters molecules based on size, charge membrane is less permeable to molecules having larger size more negative charge Albumin possesses both these properties hence, it does not pass through glomerular basement membrane Presence of albumin in urine would indicate nephrotic syndrome Reference: Guyton & Hall, 14th edition pg no. 505, 506
Sample MCQ #5
Filtration pressure in glomeruli of kidney
A10 mm Hg
B6 mm Hg
C15 mm Hg
D2.0 mm Hg
Show Answer & Explanation ▾
✓ Correct Answer: A. 10 mm Hg
Net filtration pressure is 10 mm Hg Reference: Ganong, 25th edition page no.677
Sample MCQ #6
Proteoglycan present in glomerular basement membrane?
AKeratan sulphate 1
BKeratan sulphate 2
CHeparin sulphate
DChondroitin sulphate
Show Answer & Explanation ▾
✓ Correct Answer: C. Heparin sulphate
Heparan Sulphate is one of Glycosaminoglycan present on cell surfaces and contains negatively charged repels negative charge molecules and thus is important in Glomerular filtration and has role in retinal cells attachments.
Sample MCQ #7
Calculate net filtration pressure with the following data: P GC = 42 mm Hg P BC = 16 mm Hg π GC = 12 mm Hg Assume that no proteins were filtered.
A34 mm Hg
BData not sufficient
C14 mm Hg
D28 mm Hg
Show Answer & Explanation ▾
✓ Correct Answer: C. 14 mm Hg
Net Filtration Pressure = Forces favoring Filtration - Forces favoring resorption Forces favoring Filtration is P GC Forces favoring resorption is π GC and P BC So, Net Filtration Pressure = 42-12-16 = 14 mm Hg Reference: Ganong,25th edition page no.677
Sample MCQ #8
Counter current blood flow is seen in all except
AKidney
BEye
CTestis
DSmall intestine
Show Answer & Explanation ▾
✓ Correct Answer: B. Eye
Counter current system is seen in kidney, limbs, testis and intestine Reference: Ganong, 25th edition page no.685
