31
Q 
Peripheral vascular integrity (normal)--
colour:
temp:
capillary refill:
tissue turgor (edema):
A

colour: pink
temp: warm
capillary refill: 1-2 secs
tissue turgor (edema): full

32
Q 
Peripheral vascular integrity (inadequate arterial supply)--
colour:
temp:
capillary refill:
tissue turgor (edema):
A

colour: pale or white
temp: cool
capillary refill: >2secs
tissue turgor (edema): hollow or prunelike

33
Q 
Peripheral vascular integrity (inadequate venous return)--
colour:
temp:
capillary refill:
tissue turgor (edema):
A

colour: blue, cyanotic, mottled
temp: hot
capillary refill: immediate
tissue turgor (edema): distended or tense

34
Q

Is healing time faster in a compact or cancellous bone? Why?

A

Cancellous. Due to the rich blood supply.
