Unit 9

Question 1

When sodium ion reabsorption increases at the distal tubule:

Answer 1

more potassium and hydrogen ions are secreted.

Question 2

Congestive heart failure __________ cause edema and, therefore, a diuretic is ____________.

Answer 2

can; indicated

Question 3

thizaides

Answer 3

inhibits bicarbonate ion reabsorption at the PCT and chloride ion reabsorption at the ascending loop of Henle; also vasodialates

Question 4

Furosemide

Answer 4

powerful inhibition of chloride ion reabsorption from the ascending loop of Henle, vasodilates

Question 5

ethacrynic acid

Answer 5

inhibits sodium ion reabsorption from the PCT and inhibits chloride ion reabsorption from the ascending loop of Henle

Question 6

spironolactone

Answer 6

inhibits aldosterone at the DCT, decreases potassium secretion

Question 7

triamterene

Answer 7

decreases potassium secretion by antagonizing aldosterone receptors

Question 8

The pressure driven movement of nutrients from the glomerulus to Bowman’s capsule is the process of:

Answer 8

filtration

Question 9

The mechanism of action for the majority of diuretics used therapeutically is:

Answer 9

to directly or indirectly inhibit ion reabsorption

Question 10

To correct a systemic acidosis the kidney:

Answer 10

increases HCO3- reabsorption and H+ secretion
