Kidney MCQ Questions for Practice

16. More hydrogen is secreted in

alkalosis
administration of diamox
hypokalaemia
hyperventilation.

17. Most of the glucose that is filtered through the glomerulus undergoes reabsorption in the

proximal tubule
descending limp of the loop of Henle
ascending limb of the loop of Henle
distal tubule

18. Reabsorption of Na⁺

takes place in association with CL^- & HCO₃^â€“
occurs only in PT
is under control of parathormone hormone
is a passive process

19. Renal correction of acute hyperkalemia will result in

alkalosis
acidosis
increased secretion of HCO₃^-
increased secretion of H⁺

20. Select the correct answer about proximal tubules

K⁺ is secreted in exchange with the Na⁺ which is reabsorbed under the effect of aldosterone
glucose, amino acids & proteins are completely reabsorbed
only 10% of the filtered water is reabsorbed
parathormone increase phosphate reabsorption

21. Significant buffers for hydrogen ions generated in the body from anaerobic metabolism include all the following except

extracellular bicarbonate
plasma proteins
plasma lactate
inorganic phosphate

22. The ability of the kidney to excrete a concentrated urine will increase if

the permeability of the proximal tubule to water decreases
the rate of blood flow through the medulla decreases
the rate of flow through the loop of Henle increases
the activity of the Na-K pump in the loop of Henle decreases

23. The amount of H+ excreted as titratable acid bound to phosphate would be increased by all the following except

an increase in the amount of phosphate filtered at the glomerulus
an increase in the pH of the urine
an increase in the dietary intake of phosphate
an increase in the level of plasma parathyroid hormone ( PTH )

24. The amount of potassium excreted by the kidney will decreases if

distal tubular flow increases
circulating aldosterone level increase
dietary intake of potassium increase
Na+ reabsorption by the distal nephron decreases

25. The effect of antidiuretic hormone ( ADH ) on the kidney is to

increase the permeability of the distal nephron to water
increase the excretion of Na⁺
increase the excretion of water
increase the diameter of the renal artery

26. The glomerular filtration barrier is composed of all the following except

fenestrated capillary endothelium
macula densa
basement membrane
podocytes

27. The glomerular filtration rate will increase if

circulating blood volume increase
the afferent arteriolar resistance increases
the efferent arteriolar resistance decreases
the plasma protein concentration decreases

28. The greatest amount of hydrogen ion secreted by the proximal tubule is associated with

excretion of potassium ion
excretion of hydrogen ion
reabsorption of calcium ion
reabsorption of bicarbonate ion

29. The hypothalamus will effect the release of ADH in response to all the following stimuli except

dehydration
severe hemorrhage
nicotine
pain, anxiety, or surgical stress

30. The primary renal site for the secretion of organic ions e.g urate, creatinine is

proximal tubule
loop of Henle
distal tubule
collecting duct
