Deal with nurse (5)
I believe the answer is:
treat
This clue is a double definition.
'deal with' is the first definition.
('treat' can be a synonym of 'deal with')
'nurse' is the second definition.
(thesaurus)
(Other definitions for treat that I've seen before include "Delightful outing; pay for (someone else)" , "Event causing special pleasure" , "Handle; dainty" , "Entertain at one's own expense" , "Deal with; an outing" .)
