Likelihood of seeing nurse outside hospital? (6)
I believe the answer is:
threat
'likelihood' is the definition.
(threat can mean danger or likelihood)
'seeing nurse outside hospital?' is the wordplay.
'seeing nurse' becomes 'treat' (I've seen this before).
'outside' means one lot of letters goes inside another.
'hospital?' becomes 'h' (abbreviation for hospital on maps).
'treat' placed around 'h' is 'THREAT'.
'of' acts as a link.
(Other definitions for threat that I've seen before include "Intimidation or warning" , "Possibility of danger" , "Menace of impending evil" , "Declaration of intention to harm another" , "An intimidatory warning" .)
