Accompany a nurse taking another temperature (6)
I believe the answer is:
attend
'accompany' is the definition.
(I know this)
'a nurse taking another temperature' is the wordplay.
'nurse' becomes 'tend' (tend can mean to nurse or look after).
'taking' means one lot of letters goes inside another.
'another temperature' becomes 't' (abbreviation. I am not sure about the 'another' bit.).
'tend' going around 't' is 'ttend'.
'a'+'ttend'='ATTEND'
(Other definitions for attend that I've seen before include "Show up" , "Pay heed" , "Completed" , "Concentrate carefully" , "Go regularly to (school)" .)
