I believe the answer is:

endpaper

I'm a little stuck... Click here to teach me more about this clue!

'up last sheet' is the definition.
The definition suggests a singular noun which matches the answer.

'nurse rapped for messing' is the wordplay.
'nurse' becomes 'EN' (abbreviation for enrolled nurse).
'for messing' is an anagram indicator.
'rapped' with letters rearranged gives 'dpaper'.
'en'+'dpaper'='ENDPAPER'

Can you help me to learn more?

(Other definitions for endpaper that I've seen before include "goes into bookmaking?" , "found at beginning of book" , "part of book" , "One's stuck in a book" .)
