Answer to Question 1

ANS: C
The pressure of blood as it is pushed against an artery is detected as a pulse. Increased pulse amplitude indicates increased blood flow. Coolness and decreased sensation usually correlate with decreased blood perfusion. Paleness or blanching does not indicate increased blood perfusion.

Answer to Question 2

ANS: C
Pentoxifylline enhances red blood cell (erythrocyte) flexibility, which reduces blood viscosity. This allows for more blood to perfuse into the tissues. Muscle tissues become better oxygenated and intermittent claudication is reduced. Pentoxifylline does not cause vasodilation. Pentoxifylline acts to decrease clotting and decreases blood viscosity.
