Nurse expected to provide ... (5)
I believe the answer is:
endue
'provide' is the definition.
(I've seen this before)
'nurse expected' is the wordplay.
'nurse' becomes 'EN' (abbreviation for state-enrolled nurse).
'expected' becomes 'due' (similar in meaning).
'en'+'due'='ENDUE'
'to' is the link.
(Other definitions for endue that I've seen before include "Clothe" , "Supply or provide" , "Invest - provide" , "Make investment" , "Supply (with a quality/ability)" .)
