Visit nurse after a short time (6)
I believe the answer is:
attend
'visit' is the definition.
(I've seen this before)
'nurse after a short time' is the wordplay.
'nurse' becomes 'tend' (I've seen this before).
'after' says to put letters next to each other.
'short time' becomes 't' (abbreviation for time).
'a'+'t'='at'
'tend' after 'at' is 'ATTEND'.
(Other definitions for attend that I've seen before include "Be present or appear at" , "Wait and listen" , "Watch" , "Completed" , "Wait upon or be present" .)
