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

'source of 1' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'medic hurt possibly carrying setter's' is the wordplay.
'medic' becomes 'dr' (abbreviation for doctor).
'possibly' indicates anagramming the letters.
'carrying' means one lot of letters goes inside another.
'setter's' becomes 'ive' ('I've', referring to the crossword setter).
'hurt' is an anagram of 'thru'.
'thru' enclosing 'ive' is 'ivethru'.
'dr'+'ivethru'='DRIVE-THRU'
