adhere to wound bed, provides no
residue.
May or may not have an adhesive
border; if none, will need
securement

*primary= shallow minimally draining wound
secondary= deep cavity wound

Question 19

what special characteristics are there for hydrocolloids?

Answer 19

Combo of gel-forming polymers
with adhesives into backing of film
or foam; conforms to body shape
Does not require a secondary
dressing

Answer 22

semi-occlusive/semi-permeability

Question 23

what are the special characteristics of transparent films?

Answer 23

Provides no absorbency; moisture
vapor and O2 permeable
