45
is NG feeding covered under certification for eating disorders
yes
46
can anyone accurately predict when a starved individual will due? why or why not?
no, no one can accurately predict this because it is not always low weight related hypoglycemia can be asymptomatic until very low (i.e below 1.5) many case reports and case series document assoc. of hypoglycemia with mortality in AN (glucose less than 2.5)

SCOFF questionnaire --do you make yourself Sick because you feel uncomfortably full --do you worry that you have lost Control over how much you eat --have you recently lost more than One stone (14 pounds) in a 3 month period --do you think you are too Fat, even though others say you are too thin --would you say that Food dominates your life 5 item/brief measure scoring is dichotomous --> score of 1 (symptoms endorsed on at least one item) has been recommended as positive screen
55
what ED specific questions should be asked on assessment
food/fluid intake on average day (when, what) specifics of intake (i.e a sandwich can be many things) self induced or spontaneous vomiting--how, when, frequency binges --size, content, frequency over the counter or naturopathic meds, supplements, laxatives, enemas, diuretics (teas) food rituals, phobias, rules chewing and spitting excercise (walking, aerobics, weights)--duration and frequency history of weight over time (highest, lowest, ideal) how often weighing self, impact on wellbeing desire to lose weight body image how much time spent thinking about food/weight/shape
