Concept of Anxiety and Psychiatric Nursing

• Anxiety– Universal human experience– Dysfunctional behavior often defends against

anxiety

• Legacy of Hildegard Peplau (1909-1999)– Operationally defined concept and levels of anxiety– Suggested specific nursing interventions

appropriate to each of four levels of anxiety

Page 3: Anxiety  Anxiety Disorders

Psychological Adaptation to Stress

• Anxiety and grief have been described as two major, primary psychological response patterns to stress.

• A variety of thoughts, feelings, and behaviors are associated with each of these response patterns.

• Adaptation is determined by the extent to which the thoughts, feelings, and behaviors interfere with an individual’s functioning.

Page 4: Anxiety  Anxiety Disorders

Anxiety and Fear

• Anxiety: feeling of apprehension, uneasiness, uncertainty, or dread resulting from real or perceived threat whose actual source is unknown or unrecognized

• Fear: reaction to specific danger

• Similarity between anxiety and fear– Physiological response to these experiences is

the same (fight-or-flight response)

Page 5: Anxiety  Anxiety Disorders

Anxiety

• A diffuse apprehension that is vague in nature and is associated with feelings of uncertainty and helplessness.

• Extremely common in our society. • Mild anxiety is adaptive and can provide

motivation for survival.

Page 6: Anxiety  Anxiety Disorders

Types of Anxiety• Normal

– Motivating force that provides energy to carry out tasks of living

• Acute or state– Anxiety that is precipitated by imminent loss or change that

threatens one’s security (crisis)• Chronic or trait

– Anxiety that persists over time

• Mild

– Occurs in normal everyday living

– Increases perception, improves problem solving

– Manifested by restlessness, irritability, mild tension-relieving behaviors

Page 7: Anxiety  Anxiety Disorders

Types of Anxiety• Moderate

– Escalation from normal experience

– Decreases productivity (selective inattention) and learning

– Manifested by increased heart rate, perspiration, mild somatic symptoms

• Severe– Greatly reduced perceptual field– Learning and problem solving not possible– Manifested by erratic, uncoordinated, and impulsive behavior

• Panic– Results in loss of reality focus– Markedly disturbed behavior occurs– Manifested by confusion, shouting, screaming, withdrawal

Page 8: Anxiety  Anxiety Disorders

Peplau’s four levels of anxiety

• Mild – seldom a problem

• Moderate – perceptual field diminishes

• Severe – perceptual field is so diminished that concentration centers on one detail only or on many extraneous details

• Panic – the most intense state

Page 9: Anxiety  Anxiety Disorders

Behavioral adaptation responses to anxiety

• At the mild level, individuals employ various coping mechanisms to deal with stress. A few of these include eating, drinking, sleeping, physical exercise, smoking, crying, laughing, and talking to persons with whom they feel comfortable.

Defense Mechanisms

• Help protect people from painful awareness of feelings and memories that can cause overwhelming anxiety– Operate all the time– Adaptive (healthy) or maladaptive (unhealthy)

• First outlined and described by Sigmund Freud and his daughter Anna Freud

Page 12: Anxiety  Anxiety Disorders

Properties of Defense Mechanisms

• Major means of managing conflict and affect

• Relatively unconscious

• Discrete from one another

• Hallmarks of major psychiatric disorders

• Can be reversible

• Can be adaptive as well as pathological

Page 13: Anxiety  Anxiety Disorders

Healthy, Intermediate, and Immature Defense Mechanisms

• Healthy– Altruism, sublimation, humor, suppression

• Intermediate– Repression, displacement, reaction formation,

undoing, rationalization

• Immature– Passive aggression, acting-out behaviors,

dissociation, devaluation, idealization, splitting, projection, denial

Page 14: Anxiety  Anxiety Disorders

Defense Mechanisms

– Compensation– Denial– Displacement– Identification– Intellectualization– Introjection– Isolation– Projection

– Rationalization

– Reaction formation

– Regression

– Repression

– Sublimation

– Suppression

– Undoing

Page 15: Anxiety  Anxiety Disorders

• Anxiety at the moderate to severe level that remains unresolved over an extended

period of time can contribute to a number of physiological disorders – for example, migraine headaches, IBS, and cardiac arrhythmias.

• Extended periods of repressed severe anxiety can result in psychoneurotic patterns of behaving – for example, anxiety disorders and somatoform disorders.

Page 16: Anxiety  Anxiety Disorders

Introduction: Anxiety Disorder

Anxiety provides the motivation for achievement, a necessary force for survival.

Anxiety is often used interchangeably with the word stress; however, they are not the same.

Anxiety may be differentiated from fear in that the former is an emotional process, whereas fear is cognitive.

Page 17: Anxiety  Anxiety Disorders

• Extended periods of functioning at the panic level of anxiety may result in psychotic behavior; for example, schizophrenic, schizoaffective, and delusional disorders.

Page 18: Anxiety  Anxiety Disorders

Epidemiological statistics

– Anxiety disorders are the most common of all psychiatric illnesses

– More common in women than men

– Minority children and children from low socioeconomic environments at risk

– A familial predisposition probably exists

• How much is too much?– When anxiety is out of proportion to the situation that is

creating it.– When anxiety interferes with social, occupational, or other

important areas of functioning.

Page 19: Anxiety  Anxiety Disorders

Predisposing Factors

• Psychodynamic theory

• Cognitive Theory

• Biological aspects

• Transactional Model of Stress Adaptation

Page 20: Anxiety  Anxiety Disorders

Panic Disorders: Panic Attack, Panic Disorder with Agoraphobia• Panic attack

– Sudden onset of extreme apprehension or fear of impending doom

– Fear of losing one’s mind or having a heart attack

• Panic disorder with agoraphobia– Panic attacks combined with agoraphobia

• Agoraphobia is fear of being in places or situations from which escape is difficult or help unavailable

– Feared places avoided, restricting one’s life

Page 21: Anxiety  Anxiety Disorders

Phobia

• Phobia: persistent, irrational fear of specific objects, activities, or situations

• Types of phobias– Specific: response to specific objects– Social: result of exposure to social situations or

required performance– Agoraphobia: fear of being in places/situations

from which escape is difficult or help unavailable

Page 22: Anxiety  Anxiety Disorders

Obsessive-Compulsive Disorder (OCD)

• Obsession– Thoughts, impulses, or images that persist and recur

• Ego-dystonic symptom: feels unacceptable to individual

• Unwanted, intrusive, persistent ideas, thoughts, impulses, or images that cause marked anxiety or distress

Page 23: Anxiety  Anxiety Disorders

Compulsions

• Ritualistic behaviors that individual feels driven to perform

• Primary gain from compulsive behavior: anxiety relief

• Unwanted repetitive behavior patterns or mental acts that are intended to reduce anxiety, not to provide pleasure or gratification

Page 24: Anxiety  Anxiety Disorders
Page 25: Anxiety  Anxiety Disorders

Generalized Anxiety Disorder (GAD)

• Excessive anxiety or worry about numerous things lasting at least 6 months

• Common symptoms

– Restlessness

– Fatigue

– Poor concentration

– Irritability

– Tension

– Sleep disorders

Page 26: Anxiety  Anxiety Disorders

Post-traumatic Stress Disorder (PTSD)

– Development of characteristic symptoms following exposure to an extreme traumatic stressor involving a personal threat to physical integrity or to the physical

integrity of others – Characteristic symptoms include reexperiencing the

traumatic event, a sustained high level of anxiety or arousal, or a general numbing of responsiveness. Intrusive recollections or nightmares of the event are common.

Page 27: Anxiety  Anxiety Disorders

• Psychosocial theory– The traumatic experience

• Severity and duration of the stressor• Extent of anticipatory preparation before onset• Exposure to death• Numbers affected by life threat• Extent of control over recurrence• Location where trauma was experienced

– The individual• Degree of ego-strength• Effectiveness of coping resources• Presence of preexisting psychopathology

– Outcomes of previous experiences with stress/trauma– Behavioral tendencies– Current psychosocial developmental stage– Demographic factors

Page 28: Anxiety  Anxiety Disorders

– The recovery environment• Availability of social supports

• Cohesiveness and protectiveness of family and friends

• Attitudes of society regarding the experience

• Cultural and subcultural influences

• Learning theory– Negative reinforcement as behavior that leads to a reduction in an

aversive experience, thereby reinforcing and resulting in repetition of the behavior

– Avoidance behaviors– Psychic numbing

• Cognitive theory– A person is vulnerable to post-traumatic stress disorder when

fundamental beliefs are invalidated by experiencing trauma that cannot be comprehended and when a sense of helplessness and hopelessness prevails.

Page 29: Anxiety  Anxiety Disorders

Treatment Modalities

• Psychopharmacology – PTSD

• Antidepressants

• Anxiolytics

• Antihypertensives

• Others

Page 30: Anxiety  Anxiety Disorders

• Biological aspects– It has been suggested that a person who has experienced

previous trauma is more likely to develop symptoms after a stressful life event.

– Disregulation of the opioid, glutamatergic, noradrenergic, serotonergic, and neuroendocrine pathways may be involved in the pathophysiology of PTSD.

• Transactional Model of Stress Adaptation– The etiology of PTSD is most likely influenced by multiple

factors

Page 31: Anxiety  Anxiety Disorders

Acute Stress Disorder• Occurs within 1 month after exposure to highly

traumatic event • Characterized by at least three dissociative symptoms

during/after event– Subjective sense of numbing– Reduction in awareness of surroundings– Derealization– Depersonalization– Dissociative amnesia

Page 32: Anxiety  Anxiety Disorders

Anxiety Caused by Medical Conditions

• Direct physiological result of medical conditions such as:– Hyperthyroidism– Pulmonary embolism– Cardiac dysrhythmias

• Evidence must be present in history, physical exam, or laboratory findings in order to diagnose

Page 33: Anxiety  Anxiety Disorders

Nursing Process: Assessment Guidelines

• Determine if anxiety is primary or secondary (due to medical condition)– Ensure sound physical/neurological exam

• Use of Hamilton Rating Scale– Comprehensive data related to anxiety

• Determine potential for self-harm/suicide

• Perform psychosocial assessment

• Determine cultural beliefs and background

Page 34: Anxiety  Anxiety Disorders

Nursing Process: Diagnosis and Outcomes Identification

• NANDA-International (NANDA-I) – Nursing diagnoses useful for patient with

anxiety or anxiety disorder

• Nursing Outcomes Classification (NOC)– Identifies desired outcomes for patients with

anxiety or anxiety disorders

Page 35: Anxiety  Anxiety Disorders

Considerations for Outcome Selection for Patients with Anxiety Disorders

• Reflect patient values and ethical and environmental situations

• Be culturally relevant

• Be documented as measurable goals

• Include a time estimate of expected outcomes

Page 36: Anxiety  Anxiety Disorders

Nursing Process: Planning and Implementation

• Planning– Select interventions that can be implemented in

a community setting– Include patient in process of planning

• Implementation– Follow Psychiatric–Mental Health Nursing:

Scope and Standards of Practice (ANA, 2007)

Page 37: Anxiety  Anxiety Disorders

Nursing Interventions for Patients with Anxiety Disorders

• Identify community resources offering specialized treatments proven as effective

• Identify community support groups

• Use therapeutic communication, milieu therapy, promotion of self-care activities, and psychobiological and health teaching and health promotion

Page 38: Anxiety  Anxiety Disorders

Nursing Interventions:

• Milieu Therapy

• Cognitive-Behavioral Therapy (CBT)

Nursing Diagnosis

• Risk for injury• Risk for activity intolerance• Risk for acute confusion

Page 43: Anxiety  Anxiety Disorders

Planning/Implementation• Monitor client for these side effects

– Drowsiness, confusion, lethargy; tolerance; physical and psychological dependence; potentiation of other CNS depressants; aggravation of depression; orthostatic hypotension; paradoxical excitement; dry mouth; nausea and vomiting; blood dyscrasias; delayed onset (with buspirone only)
