Put on pressure dealing with nurse (7)
I believe the answer is:
pretend
'put on' is the definition.
(thesaurus)
'pressure dealing with nurse' is the wordplay.
'pressure' becomes 'p' (abbreviation).
'dealing with' becomes 're' (regarding).
'nurse' becomes 'tend' (I've seen this before).
'p'+'re'+'tend'='PRETEND'
(Other definitions for pretend that I've seen before include "Imaginary, make-believe" , "Simulate, feign" , "Dissemble" , "bluff" , "Profess falsely" .)
