Q

What is the final phase of inflammatory response?

A

72
Q

Healing includes what 2 major components and their definitions?

A

-Regeneration - replacement of lost cells and tissues with cells of the same type

A

dryness

92
Q

What should not be used on a healing wound when cleaning a granulating wound?

What is a common drain used with surgical wounds to remove excess fluids?

A

Jackson-Pratt

94
Q

Debridement

A

removal of dead tissue and debris

95
Q
