Doctor embraces home care (4)
I believe the answer is:
Here is my best explanation:
'care' is the definition.
'doctor embraces home' is the wordplay.
'doctor' becomes 'md' ('MD' can be a synonym of 'doctor'**).
'embraces' is an insertion indicator.
'home' becomes 'in' ('he's home' can mean 'he's in').
'md' placed around 'in' is 'MIND'.
(Other definitions for mind that I've seen before include "Take care of; intellect", "Look after", "Seat of the faculty of reason", "Object to, intellect", "Intellect; object to", "Object to; take care of", "Intellect; care", "Take offence (at)", "remember" and "This can be made up".)
