During recovery from a serious surgery or trauma, how much water is likely to be produced in a 24-hr period by the catabolism of fat and proteins?
 
  a. 300 ml
  b. 500 ml
  c. 750 ml
  d. 1000 ml

Question 2

What is the net effect of the hydrostatic pressure gradient between the capillary and interstitial space?
 
  a. It tends to push water into the capillaries.
  b. It tends to push water into the interstitial spaces.
  c. The pressure gradient is zero so fluid movement is due to osmosis.
  d. It tends to push water into the cells.

Answer to Question 1

ANS: D
Recovery after surgery or trauma may be similar to starvation. Under such conditions, approxi-mately 500 mg of protein and a similar amount of fat are metabolized. This yields approximately 1 L of water per day.

Answer to Question 2

ANS: B
Movement of fluid and solutes from capillary blood to interstitial spaces is enhanced by the dif-ference in hydrostatic pressure between compartments. Hydrostatic pressure difference depends on blood pressure, blood volume, and the vertical distance of the capillary from the heart (i.e., the effects of gravity). Hydrostatic pressure tends to cause fluid to leak out of capillaries into the in-terstitial spaces.
