nursing interventions for anorexia nervosa
- building trust and establish a therapeutic alliance
- psychoeducation

what is refeeding syndrome
rare but potentially fatal condition that can occur during refeeding of malnourished individuals
due to the metabolic and hormonal changes that occur due to aggressive nutritional rehab
can cause severe electrolyte imbalances
who is at risk for refeeding syndrome?
- any pt resulting in rapid weight loss of 15-20% over 3-6 months
- 10 days of low intake or starvation
- pts receiving enteral or parenteral feeds
manifestations of refeeding syndrome
hyperglycemia, fluid retention, dysrhythmias, heart failure, respiratory failure, anemia, delirium, weakness
how can we prevent refeeding syndrome?
- start low and go slow when increasing kcal intake
- MONITOR pt presentation closely
- adjust fluid, electrolyte, vitamin, and mineral requirements based on lab work
- provide thiamine and complete multivitamin
bulimia nervosa

what should we assess for in binge eating disorder pts?

- physical mobility, activity and sleep patterns
- cognitive distortions & knowledge gaps
- symptoms of comorbid psychiatric disorders
- MSE & risk
what are the priority care issues for BED?f
comorbid obesity, depression and anxiety can contribute to cardiac and other health crises
- also risk of type 2 diabetes in presence of obesity
nursing interventions for BED
- building the therapeutic relationship
- psychotherapy (addressing cognitive distortions with CBT)
- encourage clients to record intake, binges and emotions associated
- pharmacological intervention for weight loss (Vyvanse)
- establishing health sleep and coping patterns
