1- Local increases in hydrostatic pressure may result from impaired venous outflow?
A) True
B) False
The correct answer was "True" — For example, deep venous thrombosis (DVT) in the lower
extremities leads to edema, which is restricted to the affected leg.
2- Which of the following proteins is most responsible for maintaining colloid osmotic pressure?
A) Renin
B) Albumin
C) Angiotensin
Albumin is the serum protein most responsible for maintaining colloid osmotic pressure.
3- Increased salt, with the obligate accompanying water, causes both increased hydrostatic
pressure and diminished vascular colloid osmotic pressure?
A) True
B) False
4- Hyperemia is a passive process whereas congestion is an active process?
A) True
B) False
The correct answer was "False" — Hyperemia is an active process resulting from augmented tissue
inflow because of arteriolar dilation, and the affected tissue becomes redder. Congestion is a passive
process resulting from an isolated venous obstruction. The affected tissue has a blue-red color
(cyanosis).
5- Which of the following processes describes extravasation of blood due to vessel rupture?
A) Congestion
B) Hyperemia
C) Hemorrhage
6- Which of the following describes a minute 1 to 2mm hemorrhage?
A) Petechiae
B) Purpura
C) Ecchymoses
A) True
B) False
The correct answer was "True" — For example, deep venous thrombosis (DVT) in the lower
extremities leads to edema, which is restricted to the affected leg.
