Bulimia nervosa,
Binge eating
______ _______ is a disorder where the patient refuses to maintain a minimum normal weight for height and expresses an intense fear of normal weight gain.
Anorexia nervosa
_____ ____ can include the restriction of food intake and/or binge eating and purging
Anorexia nervosa
_____ _____ is an eating disorder where the patient engages in repeated episodes of binge eating followed by inappropriate compensatory behaviors, such as self-induced vomiting; misuse of laxatives, diuretics, or other medications; fasting; or excessive exercise.
Bulimia nervosa
Individuals with _____ _____ disorder engage in repeated episodes of binge eating, after which they experience significant distress. This pattern inevitably causes obesity.
Binge eating
What is the physical criteria for hospitalization of patients with eating disorders?
Weight loss of 30% in 6 months, Heart rate less than 40 bpm, Systolic BP less than 70 mmHg, Arrhythmias, Hypokalemia (less than 3 mEQ/L) or other electrolyte imbalances, Hypothermia or dehydration
What is the psychiatric criteria for hospitalization of patients with eating disorders?
Suicidal ideation, Self-mutilating behavior, Extreme use of laxatives, emetics, diuretics, or street drugs, Non-compliance with treatment contract, Psychosis, Family crisis/dysfunction
What is a common etiology among those with eating disorders?
Childhood trauma,
Sexual abuse,
Physical neglect,
Emotional abuse
What are the biological factors related to eating disorders?
Heritability (poor affect and impulse control), Altered serotonin (causes dysregulation of appetite, mood and impulse control)
______ is an amino acid that is essential to serotonin synthesis and is available thru diet. Temporary drops in the level of this amino acid may relieve symptoms of anxiety and dysphoria and provide a reward for caloric restriction
Tryptophan
What are the signs and symptoms of anorexia nervosa?
Low weight, Amenorrhea, Yellow skin, Lanugo, Cold extremities, Peripheral edema, Muscle weakening, Constipation, Cardiovascular abnormalities (hypotension, bradycardia, heart failure), Impaired renal function. Hypokalemia, Anemic pancytopenia, Decreased bone density, Abnormal lab values (liver function)
A comprehensive nursing assessment of a patient with an eating disorder includes….
Patient perception of problem,
Eating habits,
History of dieting,
Methods of weight control (restricting, purging, exercising),
Determine patient value on specific shape/weight,
Interpersonal/social functioning,
Mental status/physiological parameters
Immediate medical stabilization is required if a patient experiences extreme _____ ______ and/or weighs below ____% of ideal body weight.
Electrolyte imbalance,
75%
A severe shift in electrolytes occurs when a patient consumes a quantity of complex carbohydrates after a prolonged period of deprivation. This causes fluid imbalances that can lead to potentially fatal conditions of Hypophosphatemia (low phosphates in the blood stream) and heart failure
Refeeding syndrome
What is the treatment goal for a patient with an eating disorder?
90% of ideal body weight
This is the weight appropriate to restore and maintain menses
What are appropriate nursing interventions for those with anorexia nervosa?
Provide structured environment with precise meal times,
Adherence to a selected menu,
Observation during and after meals,
Regularly scheduled weighing,
Monitor all trips to bathroom to prevent self-induced vomiting,
Monitor bathroom trips post visitors to monitor for emetic/laxative misuse
What are the signs and symptoms of bulimia nervosa?
Normal/slightly low weight, Dental caries/tooth erosion, Parotid swelling (increased serum amylase levels), Gastric dilation, Hand calluses/scars (Russell's sign), Peripheral edema, Muscle weakening, Abnormal electrolytes, Cardiovascular abnormalities, Cardiac failure (ipecac intoxification)
What is the priority nursing intervention for bulimia nervosa?
Medical stabilization (fluid/electrolyte balance, cardiac function)
What are the laboratory tests that should be run for a patient with bulimia nervosa?
Electrolyte levels, Glucose levels, Thyroid function, CBC, ECG
What are appropriate nursing interventions for those with bulimia nervosa?
Observation during and after meals,
Normalization of eating patterns,
Maintenance of appropriate exercise
What are signs and symptoms of binge eating?
Heartburn,
Dysphasia,

Major depression,
Substance abuse,
OCD

Hypertension,
Heart disease
This is a result of obesity
What is the primary pharmacological intervention for binge eating disorder related to obesity?
