Inattentive? Doctor please! (6)
I believe the answer is:
asleep
'inattentive?' is the definition.
(I've seen this before)
'doctor please' is the wordplay.
'doctor' indicates anagramming the letters.
'please' with letters rearranged gives 'ASLEEP'.
(Other definitions for asleep that I've seen before include "Resting unconscious" , "In the arms of Hypnos" , "Having nodded off" , "Dead to the world" , "In slumber" .)
