300.02 Generalized anxiety disorder
Although some degree of anxiety is normal in life’s stresses, anxiety can be adaptive or maladaptive. Problems arise when the client has coping mechanisms that are inadequate to deal with the danger, which may be recognized or unrecognized. The essential feature of this inadequacy is unrealistic or excessive anxiety and worries about life circumstances. Anxiety disorders are the most common of all major groups of mental disorders in the United States, sharing comorbidity with major depression and substance abuse, increasing the client’s risk of suicide.
ETIOLOGICAL THEORIES
Psychodynamics
The Freudian view involves conflict between demands of the id and superego, with the ego serving as mediator. Anxiety occurs when the ego is not strong enough to resolve the conflict. Sullivanian theory states that fear of disapproval from the mothering figure is the basis for anxiety. Conditional love results in a fragile ego and lack of self-confidence. The individual with anxiety disorder has low self-esteem, fears failure, and is easily threatened.
Dollard and Miller (1950) believe anxiety is a learned response based on an innate drive to avoid pain. Anxiety results from being faced with two competing drives or goals.
Cognitive theory suggests that there is a disturbance in the central mechanism of cognition or information processing with the consequent disturbance in feeling and behavior. Anxiety is maintained by this distorted thinking with mistaken or dysfunctional appraisal of a situation. The individual feels vulnerable, and the distorted thinking results in a negative outcome.
Biological
Although biological and neurophysiological influences in the etiology of anxiety disorders have been investigated, no relationship has yet been established. However, there does seem to be a genetic influence with a high family incidence.
The autonomic nervous system discharge that occurs in response to a frightening impulse and/or emotion is mediated by the limbic system, resulting in the peripheral effects of the autonomic nervous system seen in the presence of anxiety.
Some medical conditions have been associated with anxiety and panic disorders, such as abnormalities in the hypothalamic-pituitary-adrenal and hypothalamic-pituitary-thyroid axes, acute myocardial infarction, pheochromocytomas, substance intoxication and withdrawal, hypoglycemia, caffeine intoxication, mitral valve prolapse, and complex partial seizures.
Family Dynamics
The individual exhibiting dysfunctional behavior is seen as the representation of family system problems. The “identified patient” (IP) is carrying the problems of the other members of the family, which are seen as the result of the interrelationships (disequilibrium) between family members rather than as isolated individual problems.
It is recognized that multiple factors contribute to anxiety disorders.
CLIENT ASSESSMENT DATA BASE
Activity/Rest
Restlessness, pacing anxiously, or, if seated, restlessly moving extremities
Feeling “keyed up”/“on edge,” unable to relax
Easily fatigued
Difficulty falling or staying asleep; restlessness, unsatisfying sleep
Circulation
Heart pounding or racing/palpitations; cold and clammy hands; hot or cold spells, sweating; flushing, pallor
High resting pulse, increased blood pressure
Ego Integrity
Excessive worry about a number of events/activities, occurring more days than not for at least 6 months
Complains vociferously about inner turmoil, has difficulty controlling worry
May demand help
Facial expression in keeping with level of anxiety felt (e.g., furrowed brow, strained face, eyelid twitch)
May report history of threat to either physical integrity (illness, inadequate food and housing, etc.) or self-concept (loss of significant other; assumption of new role)
Elimination
Frequent urination; diarrhea
Food/Fluid
Lack of interest in food, dysfunctional eating pattern (e.g., responding to internal cues other than hunger)
Dry mouth, upset stomach, discomfort in the pit of the stomach, lump in the throat
Neurosensory
Absence of other mental disorder, such as depressive disorder or schizophrenia
Motor tension: shakiness, jitteriness, jumpiness, trembling, muscle tension, easily
startled
Dizziness, lightheadedness, tingling hands or feet
Apprehensive expectation: anxiety, worry, fear, rumination, anticipation of misfortune to self or others, inability to act differently (feeling stuck)
Excessive vigilance/hyperattentiveness resulting in distractibility, difficulty in concentrating or mind going blank, irritability, impatience
Free-floating anxiety usually chronic or persisting over weeks/months
Pain/Discomfort
Muscle aches, headaches
Respiratory
Increased respiratory rate, shortness of breath, smothering sensation
Sexuality
Women twice as likely to be affected as men
Social Interactions
Significant impairment in social/occupational functioning
Teaching/Learning
Age of onset usually 20s and 30s
DIAGNOSTIC STUDIES
Drug Screen: Rules out drugs as contribution to cause of symptoms.
Other diagnostic studies may be conducted to rule out physical disease as basis for individual symptoms (e.g., ECG for severe chest pain, echocardiogram for mitral valve prolapse; EEG to identify seizure activity; thyroid studies).
NURSING PRIORITIES
1. Assist client to recognize own anxiety.
2. Promote insight into anxiety and related factors.
3. Provide opportunity for learning new, adaptive coping responses.
4. Involve client and family in educational/support activities.
DISCHARGE GOALS
1. Feelings of anxiety recognized and handled appropriately.
2. Coping skills developed to manage anxiety-provoking situations.
3. Resources identified and used effectively.
4. Client/family participating in ongoing therapy program.
5. Plan in place to meet needs after discharge.
