I need a thesis paper on school nursing.
Does anxiety trigger chronic absenteeism? Do the absent students show any psychosomatic signs of anxiety (stomach ache, tachycardia)? When the students return to school, how often do they visit the school nurse? this is my research question. I need to be highly involved in writing this thesis. I have 2 semesters to write it.
