Blanket nurse and staff see about (7)
I believe the answer is:
envelop
'blanket' is the definition.
(I've seen this before)
'nurse and staff see about' is the wordplay.
'nurse' becomes 'EN' (abbreviation for enrolled nurse).
'and' means one lot of letters go next to another.
'staff' becomes 'pole' (I've seen this before).
'see' becomes 'v' (short for 'vide', Latin meaning 'see elsewhere').
'about' shows that the letters should be reversed in order.
'pole'+'v'='polev'
'polev' backwards is 'velop'.
'en'+'velop'='ENVELOP'
(Other definitions for envelop that I've seen before include "Swathe" , "Enfold, enwrap" , "Obscure" , "Ring" , "blanket" .)
