Doctor at home following adult's bleed (5)
I believe the answer is:
drain
'bleed' is the definition.
(thesaurus)
'doctor at home following adult's' is the wordplay.
'doctor' becomes 'dr' ('Dr' can be a synonym of 'doctor').
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'following' is a charade indicator (letters next to each other).
'adult' becomes 'a'.
'in' put after 'a' is 'ain'.
'dr'+'ain'='DRAIN'
(Other definitions for drain that I've seen before include "Remove liquid from" , "Empty of liquid" , "Exhaust (of liquid)" , "Exhaust - pipe" , "Bleed" .)
