Rise in support given to a new nurse? (5)
I believe the answer is:
angel
'nurse?' is the definition.
(collins dictionary)
'rise in support given to a new' is the wordplay.
'rise in' is a reversal indicator.
'support' becomes 'leg' (leg is a kind of support**).
'given to' is a charade indicator (letters next to each other).
'a new' becomes 'an' (I've seen this in other clues).
'leg' backwards is 'gel'.
'gel' after 'an' is 'ANGEL'.
(Other definitions for angel that I've seen before include "darling!" , "Theatrical backer" , "Messenger < is a nurse" , "backer for rep" , "Ministering spirit" .)
