Kidney related questions-help needed

[ch5112]

Hi I was going through my past exam paper and it doesn't provide answers for it...

 

I wrote down the answers for every questions. Can you please check whether i am right or not please?

 

 

 

Q1.

 

Predict which one of the following people would initially produce the greatest urine volume?

 

a.A person who is given some synthetic Vasopressin which acts in the same manner as the natural hormone

 

b.A person who drinks 500mL of isotonic sports drink

 

c.A person who drinks 500mL of water

 

d.A person who eats salty chips and then drinks 500mL of isotonic sports drink

 

e.A person who eats salty chips and then drinks 500mL of water

 

 

For this question, I think correct answer should be ©....?

 

 

 

Q2.

 

In a normal kidney, glomerular filtration rate would decrease in all of the following conditions EXCEPT FOR:

 

a.An increase in the Bowman's capsule hydrostatic pressure

b.A decrease in the mean arterial pressure from 85mmHg to 60mmHg

c.A decrease in Bowman's capsule oncotic pressure

d.A decrease in plasma hydrostatic pressure

e.An increase in plasma oncotic pressure

 

 

I think correct answer for this is (a) because, hydrostatic pressure should be proportional to GFR. Thus, if there is an increase in the bowman's capsule hydrostatic pressure then GFR should increase too?

 

 

 

Q3.

 

 

Which of the following statements in regards to glucose reabsorption in the proximal tubule is INCORRECT?

 

a.Glucose concentration is higher in the tubular lumen than within the cell

b.Glucose concentration is higher in the cell than in the interstitial cell

c.Glucose diffuses out of the basolateral side of the cell using the GLUT protein

d.A decrease in the activity of the Na+/K+-ATPase would decrease glucose reabsorption

e.Glucose reabsorption occurs via secondary active transport
