Medical officer getting the right parent (6)
I believe the answer is:
mother
'parent' is the definition.
(type of parent)
'medical officer getting the right' is the wordplay.
'medical officer' becomes 'MO' (abbreviation).
'getting' is a charade indicator (letters next to each other).
'right' becomes 'r' (abbreviation).
'mo'+'the'+'r'='MOTHER'
(Other definitions for mother that I've seen before include "Dam" , "She gave birth to her Tom" , "Mum" , "Nature so-called" , "She gives birth" .)
