101.  When blood pressure is greater than the blood colloid osmotic pressure, there is  
A.  a net movement of fluid into the capillary.
B.  a net movement of fluid out of the capillary.
C.  less lymph formed.
D.  a decrease in the volume of the interstitial fluid.
E.  a decreased likelihood of edema.

102.  A force that causes the movement of fluid out of the capillary is  
A.  blood pressure.
B.  positive interstitial pressure.
C.  blood colloid osmotic pressure.
D.  critical closing pressure.
E.  lymph pressure.

103.  A force that attracts fluid into the capillary from the tissue spaces is  
A.  blood pressure.
B.  negative interstitial pressure.
C.  blood colloid osmotic pressure.
D.  venous pressure.
E.  active transport.

104.  Edema can occur when there is  
A.  an increase in the amount of plasma proteins.
B.  a decrease in capillary permeability to proteins.
C.  a decrease in blood pressure.
D.  a blockage of the lymphatics.
E.  an increase in blood colloid osmotic pressure.

105.  Which of the following is LESS likely to result in edema?  
A.  increase in capillary permeability
B.  reduced plasma colloid osmotic pressure
C.  blockage of veins
D.  increased mean arterial pressure
E.  loss of protein molecules in urine through the kidneys

106.  In which of the following clinical situations would you expect edema?  
A.  shock (which is accompanied by low blood pressure)
B.  burns (which result in increased capillary permeability to plasma proteins)
C.  dehydration (which results in low blood pressure)
D.  vomiting (which leads to a decreased plasma volume)
E.  diarrhea (which leads to a decreased blood volume)

107.  In capillary exchange, which of the following statements is true?  
A.  Most fluid that leaves the arterial end of a capillary reenters the venous end of a capillary.
B.  Interstitial fluid normally has a higher osmotic pressure than plasma.
C.  Constriction of the precapillary sphincter will increase blood pressure in the capillary.
D.  Interstitial protein concentration is normally higher than plasma protein concentration.
E.  Most fluid that leaves the arterial end of a capillary enters the lymphatic system.

108.  Which of the following factors assists in the return of venous blood to the heart?

D.  2, 3, 4
E.  1, 3, 4

109.  Increased venous tone will  
A.  relax the veins.
B.  help return blood to the heart.
C.  allow blood to pool in the veins.
D.  stabilize blood velocity in the veins.
E.  dilate the veins.

110.  Which of the following happens when a person stands in one place for a long period of time?

B.  Blood pressure rises in the venules of the feet.
C.  Without muscular movement the pressure at the venous end of the capillaries increases.
D.  Edema may occur in the lower extremities.
E.  All of these choices are correct.
