This is from an American survey, I am guessing that it would translate to Ireland fairly well.
Nurses top “most trusted” poll.
A recent Gallup Poll in which participants were asked to rate the honesty and ethical standards of various professions found that nurses have the most “very high” or “high ” ratings (85%), followed by pharmacists (75%), medical doctors (70%), dentists (62%), psychiatrists (41%), and chiropractors (38%). Journalists (38%), lawyers (19%), and members of Congress (10%), were among the lowest. [Congress retains low honesty rating. Gallup Politics Web site, Dec 3, 2012]
