Shift editor treated wounds (7)
I believe the answer is:
dressed
'treated wounds' is the definition.
'shift editor' is the wordplay.
'shift' becomes 'dress' (I've seen this before).
'editor' becomes 'ed'.
'dress'+'ed'='DRESSED'
(Other definitions for dressed that I've seen before include "Up and ready to go" , "Clothed" , "How the turkey is made oven-ready" , "Arranged" , "put bandage on" .)
