kidney related questions-need help

[ch5112]

Hi

 

I'm trying to answer these multiple questions from past exam paper. Can anyone help please? there is no answer provided

 

 

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 (d)....?

 

 

 

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

 

 

 

I think correct answer for this question is: (a).

 

 

 

Can anyone correct my answers?

No, i dont think it is d, it should be ©

http://en.wikipedia.org/wiki/Vasopressin

 

vasopressin (AVP), also known as vasopressin, argipressin or antidiuretic hormone (ADH), is a neurohypophysial hormone found in most mammals.

 

One of the most important roles of AVP is to regulate the body's retention of water; it is released when the body is dehydrated and causes the kidneys to conserve water, thus concentrating the urine and reducing urine volume.

 

And as i know isotonic sports drink will make the rehydration more effective so less urine.(sorry no link i can find for this)

how do u think ?
