'fashion' is the definition.
(I've seen this before)

'nurse gets right into' is the wordplay.
'nurse' becomes 'tend' (I've seen this before).
'gets right' becomes 'r' (I can't explain this - if you can you should give a lot more credence to this answer).
'into' is an insertion indicator.
'tend' placed around 'r' is 'TREND'.
