BASIC CONCEPT OF RENAL DISEASE 1 QUIZ

An increase in the concentration of plasma potassium causes increase in:

• release of renin

• secretion of aldosterone

• secretion of ADH

• release of natriuretic hormone

• production of angiotensin II.

Amino acids are almost completely reabsorbed from the glomerular filtrate via active transport in the:

• Proximal tubule

• loop of Henle

• distal tubule

• collecting duct

• renal pelvis

Glomerular filtration rate would be increased by:

• constriction of the afferent arteriole

• a decrease in afferent arteriolar pressure

• compression of the renal capsule

• a decrease in the concentration of plasma protein

• a decrease in renal blood flow

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

• reabsorption of phosphate ion

In controlling the synthesis and secretion of aldosterone, which of the following factors is least important?

• renin

• angiotensin II

• concentration of plasma Na+

• concentration of plasma K+

• adrenocorticotropic hormone ( ACTH)

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

• collecting duct

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

• Proximal tubule

• loop of Henle

• distal tubule

• collecting duct.

Reabsorption of Na+

• takes place in association with CL- & HCO3-

• occurs only in PT

• is under control of parathormone hormone

• is a passive process.

Diamox causes

• Water diuresis

• Hypokalemia

• alkalosis

• all of the above.

K+ excretion is markedly influenced by

• aldosterone

• amount of Na+ delivered to tubules

• rate of tubular secretion of H+

• all of the above
