Q

Nursing Screening for ED

A
  1. Questions:
    - Are you satisfied with your eating patterns?
    - Do you ever eat in secret?
    - BMI & nutritional appearance
    - ->answers will help decide if further questioning/treatment is necessary
  2. Assess diagnostic criteria for specific eating disorders
  3. Assess stage of change to determine how to intervene

A

Overestimation of the significance of undesirable events (gained 2 pounds can’t wear shorts)

26
Q

A

Believing in the cause-effect relationship of noncontingent events (If I eat a sweet it will instantly turn into stomach fat)

27
Q

Dichotomous or all-or-none thinking

A

Thinking in extreme or absolute terms such as that events can only be black or white, right or wrong, good or bad (If I eat one piece of candy I blew it and might as well eat all the candy)

28
Q

Defense Mechanisms

A

Automatic psychological processes protecting the patient from unwanted anxiety, generally the patient is unaware of using them and of the stresses that precipitate their use. Some are adaptive and some maladaptive.

29
Q

Avoidance

A

use food to avoid intimacy & other fears

30
Q

Denial

A

in anorexia this gets stronger as others express more concern about the ED

31
Q

Isolation of affect

A

inability to recognize their feelings

32
Q

Intellectualization

A

use of excessive reasoning or logic to deal with situations rather than feeling their emotions

33
Q

Overgeneralization

A

Extracting a rule on the basis of one event and applying it to other dissimilar situations (I used to be a normal weight & I wasn’t happy so I know gaining weight will not help)

34

36
Q

Bulimia Nervosa: Diagnostic Criteria

A
  1. Recurrent episodes of binge eating
    a. Rapid, episodic, impulsive, and uncontrollable ingestion of large amounts of food over a short period of time (up to 2 hours)
    b. Feelings of lack of control
    - –Restriction of total calories between binges
    - –Undue influence of body weight or shape or denial of current low weight
  2. Recurrent episodes of binge eating & compensatory purging: vomiting/laxatives, diuretics/emetics, fasting or over-exercising
  3. These episodes must occur at least once a week for a period of at least 3 months
  4. Eating –> guilt, remorse, and severe dieting. Self evaluation unduly influenced by weight. Ashamed and often conceal their eating.
37
Q

Bulimia Nervosa: Key Concepts

A

Two types of bulimia nervosa:
1. Restricting type:
Similar to anorexia nervosa-restricting is followed by binge eating, which is then followed by another period of restricting
2. Purging type- vomiting or using laxatives, diuretics, or emetics, fasting or over-exercising

Dietary restraint

  • Restricting intake is believed to explain the relationship between dieting and binge behavior
  • Restraining intake is predictive of overeating

Usually normal weight- generally not life-threatening

Present as overwhelmed and overly committed individuals who have difficulty setting limits and establishing boundaries (“social butterflies”)

Treatment is usually outpatient therapy

38
Q

Epidemiology of Bulimia

A
  • Lifetime prevalence 1 to 2.3% (more prevalent than anorexia nervosa)
  • Onset is between 15-24 years (older than anorexia nervosa)
  • Females to males 10:1
  • Related to social values of Western culture
  • Co-morbid conditions-substance use disorder, depression, and Obsessive Compulsive Disorder (OCD)
  • 1 to 4% of females; 4 to 15% in high school & college females, & 20% of nursing students and female medical students
39
Q

Bulimia Etiology: Biologic Theories

A

Neuropathologic-brain changes seen in Magnetic Resonance imaging(MRI) are result of eating dysregulation not the cause

Genetic and familial predispositions-twin studies show genetic influences are stronger than environmental

Biochemical-chronic depletion of plasma tryptophan (serotonin precursor)

40
Q

Bulimia Etiology: Psychological and Social Theories

A

Cognitive theory-cognitive distortions maintain illness instead of creating it

Family-separation/individuation-difficulty with healthy boundaries

41
Q

Clinical Course of Bulimia

A
  • Few outward signs: do great in other aspects of life
  • Binge and purge in secret
  • Treatment often delayed for years
  • Treatment initiated when control of eating is lost
42
Q

46

  • Restructuring dysfunctional thoughts and attitudes
  • Teaching healthy boundary setting
  • Resolving conflicts about separation-individuation
47

  • Antidepressants: SSRIs-Fluoxetine (Prozac) most research
  • Nutrition counseling
48
Q

Bulimia Priority Care Issues

A
  • Co-morbid depression and suicide
  • Risk for self-mutilation
  • Impulsive behavior (shoplifting, overspending, etc.)
49
Q

Binge Eating Disorder

A

consume large amounts of calories during binges & feel a lack of control & distress but do NOT try to lose weight. Most are obese. Interventions similar to bulimia nervosa.

50
Q

Motivation is a problem with ED

A

Anorexia-denial of a problem even when life threatening

Bulimia-this varies some clients do not want to change and others are motivated

Use Motivational Interviewing (MI) & stages of change when the client is not motivated. Use traditional action oriented strategies and some MI techniques during times the client is motivated

51
Q

Motivation: Case Study

A

Recent research shows that MI and Stages of Change are useful in treating the motivational problems in patients with ED.

Internal vs external motivation- ex. doing well in inpatient treatment but not after discharge

101 clients in 16 groups, not ready to change-12 week group program without any pressure to change –> 41% moved into therapy involving action

Therapist presented the assignment and left the room-90 minute sessions

Topics-

  1. Psychoeducation
  2. Function of illness
  3. Impact of illness
  4. Change, fear & recovery
  5. Evaluations and termination
52
Q

Motivational Interviewing in ED

A

Cognitive Behavioral Treatment (CBT) is generally action-oriented.

  • It is the main treatment for Bulimia and used with anorexia as well.
  • Anorexia has the behavioral components of structure to gain weight during hospitalizations.

Nurses using MI at the Weight Disorder Clinic in Australia decreased the premature discharge rate from 41% to 14%.

53
Q

Common Roadblocks to Successful Treatment

A

Admission to action oriented inpatient programs when patient is not interested in change

Primary reason for enrolling is to satisfy other people

Failure to explore ambivalence

Non-negotiable treatment actions that are not understood, not applied consistently

Repeating treatment approaches that failed in the past

54
Q

Bypassing Roadblocks to Treatment

A

Ex: patient with anorexia being committed, how patient became willing

  • Focus on patient desire to avoid commitment instead of focus on weight gain or symptoms
  • Pt agreed to attend outpt. meal support weekly & decrease exercise. Later agreed to admission.
55
Q

Nursing Approach to Treatment of ED

A
  • curious, non-judgmental,
  • clarifying dilemmas but not trying to solve them,
  • validating the position of deciding not to change,
  • respecting that eating disorders are difficult
56
Q

Self-help programs

A

NOT recommended until maintenance stage of change as they may cause a delay in seeking treatment

57
Q

How to motivate the client w/ED

A
  • -> Show empathy to the clients situation & use reflective listening to determine stage of change. Ask client to tell you about how their eating affects their life.
    1. raise subject and ask permission
    2. feedback
    3. advice
    4. enhance motivation (OARS, Readiness Ruler, Pros/Cons)
  • -> REDS:
  • rolling with resistance
  • express empathy
  • develop discrepancy between goals/behaviors
  • support self efficacy
    5. Negotiate a plan
