Nurse takes day in country (6)
I believe the answer is:
sweden
'country' is the definition.
(country in Europe)
'nurse takes day' is the wordplay.
'nurse' becomes 'sen' (abbreviation for Senior Enrolled Nurse).
'takes' indicates putting letters inside.
'day' becomes 'wed' (abbreviation for Wednesday).
'sen' placed around 'wed' is 'SWEDEN'.
'in' is the link.
(Other definitions for sweden that I've seen before include "Member country of the European Union" , "We send out to the northern state" , "N. European country" , "Stockholm's country" , "North European country" .)
