Anxiety
Anxiety: Excerpt from Signs & Symptoms: A 2-in-1 Reference for Nurses
A subjective reaction to a real or imagined threat, anxiety is a nonspecific feeling of uneasiness or dread. It may be mild, moderate, or severe. Mild anxiety may cause slight physical or psychological discomfort. Severe anxiety may be incapacitating or even life-threatening.
Everyone experiences anxiety from time to time — it’s a normal response to actual danger, prompting the body (through stimulation of the sympathetic and parasympathetic nervous systems) to purposeful action. It’s also a normal response to physical and emotional stress, which can be produced by virtually any illness. In addition, anxiety can be precipitated or exacerbated by many nonpathologic factors, including lack of sleep, poor diet, and excessive intake of caffeine or other stimulants. However, excessive, unwarranted anxiety may indicate an underlying psychological problem.
History
If the patient displays acute, severe anxiety, quickly take his vital signs and determine his chief complaint; this will serve as a guide for how to proceed. For example, if the patient’s anxiety occurs with chest pain and shortness of breath, you might suspect myocardial infarction and act accordingly. While examining the patient, try to keep him calm. Suggest relaxation techniques, and talk to him in a reassuring, soothing voice. Uncontrolled anxiety can alter vital signs and exacerbate the causative disorder.
If the patient displays mild or moderate anxiety, ask about its duration. Is the anxiety constant or sporadic? Did he notice any precipitating factors? Find out if the anxiety is exacerbated by stress, lack of sleep, or excessive caffeine intake and alleviated by rest, tranquilizers, or exercise. Obtain a complete medical history, especially noting drug use.
Physical assessment
Perform a physical examination, focusing on any complaints that may trigger or be aggravated by anxiety.
If the patient’s anxiety isn’t accompanied by significant physical signs, suspect a psychological basis. Determine the patient’s level of consciousness (LOC) and observe his behavior. If appropriate, refer the patient for psychiatric evaluation.
Medical causes
Acute respiratory distress syndrome
With acute respiratory distress syndrome (ARDS), acute anxiety occurs along with tachycardia, mental sluggishness and, in severe cases, hypotension. Other respiratory signs and symptoms include dyspnea, tachypnea, intercostal and suprasternal retractions, crackles, and rhonchi.
Anaphylactic shock
Acute anxiety usually signals the onset of anaphylactic shock. It’s accompanied by urticaria, angioedema, pruritus, and shortness of breath. Soon, other signs and symptoms develop: light-headedness, hypotension, tachycardia, nasal congestion, sneezing, wheezing, dyspnea, barking cough, abdominal cramps, vomiting, diarrhea, and urinary urgency and incontinence.
Angina pectoris
Acute anxiety may either precede or follow an attack of angina pectoris. An attack produces sharp and crushing substernal or anterior chest pain that may radiate to the back, neck, arms, or jaw. The pain may be relieved by nitroglycerin or rest, which eases anxiety.
Asthma
During allergic asthma attacks, acute anxiety occurs with dyspnea, wheezing, productive cough, accessory muscle use, hyperresonant lung fields, diminished breath sounds, coarse crackles, cyanosis, tachycardia, and diaphoresis.
Autonomic hyperreflexia
The earliest signs of autonomic hyperreflexia may be acute anxiety accompanied by severe headache and dramatic hypertension. Pallor and motor and sensory deficits occur below the level of the lesion; flushing occurs above it.
Cardiogenic shock
With cardiogenic shock, acute anxiety is accompanied by cool, pale, clammy skin; tachycardia; weak, thready pulse; tachypnea; ventricular gallop; crackles; jugular vein distention; decreased urine output; hypotension; narrowing pulse pressure; and peripheral edema.
Chronic obstructive pulmonary disease
Acute anxiety, exertional dyspnea, cough, wheezing, crackles, hyperresonant lung fields, tachypnea, and accessory muscle use characterize chronic obstructive pulmonary disease (COPD). Other signs and symptoms include barrel chest, pursed-lip breathing, and finger clubbing (late in the disease).
Heart failure
Acute anxiety is commonly the first symptom of inadequate oxygenation in a patient with heart failure. Associated findings include restlessness, shortness of breath, tachypnea, decreased LOC, edema, crackles, ventricular gallop, hypotension, diaphoresis, and cyanosis.
Hyperthyroidism
Acute anxiety may be an early sign of hyperthyroidism. Classic signs and symptoms include heat intolerance, weight loss despite increased appetite, nervousness, tremor, palpitations, sweating, an enlarged thyroid, and diarrhea. Exophthalmos may occur.
Hyperventilation syndrome
Hyperventilation syndrome produces acute anxiety, pallor, circumoral and peripheral paresthesia and, occasionally, carpopedal spasms. Other signs and symptoms include chest pain, tachycardia, belching, flatus, and dizziness.
Hypochondriasis
Mild to moderate chronic anxiety occurs with hypochondriasis. The patient focuses more on the belief that he has a specific serious disease than on the actual symptoms. Difficulty swallowing, back pain, light-headedness, and upset stomach are common complaints. The patient tends to “physician hop” and isn’t reassured by favorable physical examinations and laboratory test results.
Hypoglycemia
Anxiety resulting from hypoglycemia is usually mild to moderate and associated with hunger, mild headache, palpitations, blurred vision, weakness, and diaphoresis. Other signs and symptoms include nervousness, dizziness, and tingling and numbness around the mouth.
Mitral valve prolapse
Panic may occur in patients with mitral valve prolapse, referred to as the click-murmur syndrome. The disorder also may cause paroxysmal palpitations accompanied by sharp, stabbing, or aching precordial pain. Its hallmark is a midsystolic click, followed by an apical systolic murmur.
Mood disorder
Anxiety may be the patient’s chief complaint in the depressive or manic form of mood disorder. With the depressive form, chronic anxiety occurs with varying severity. Associated findings include dysphoria; anger; insomnia or hypersomnia; decreased libido, energy, and concentration; appetite disturbance; multiple somatic complaints; and suicidal thoughts. With the manic form, the patient’s chief complaint may be a reduced need for sleep, hyperactivity, increased energy, rapid or pressured speech and, in severe cases, paranoid ideas and other psychotic symptoms.
Myocardial infarction
With myocardial infarction, a life-threatening disorder, acute anxiety commonly occurs with persistent, crushing substernal pain that may radiate to the left arm, jaw, neck, or shoulder blades. It can be accompanied by shortness of breath, nausea, vomiting, diaphoresis, and cool, pale skin.
Obsessive-compulsive disorder
Chronic anxiety occurs with obsessive-compulsive disorder, along with recurrent, unshakable thoughts or impulses to perform ritualistic acts. The patient recognizes these acts as irrational but can’t control them. Anxiety builds if he can’t perform these acts and diminishes after he does.
Pheochromocytoma
Acute, severe anxiety accompanies the cardinal sign of pheochromocytoma: persistent or paroxysmal hypertension. Common associated signs and symptoms include tachycardia, diaphoresis, orthostatic hypotension, tachypnea, flushing, severe headache, palpitations, nausea, vomiting, epigastric pain, and paresthesia.
Phobias
With phobias, chronic anxiety occurs along with persistent fear of an object, activity, or situation that results in a compelling desire to avoid it. The patient recognizes the fear as irrational but can’t suppress it.
Postconcussion syndrome
Postconcussion syndrome may produce chronic anxiety or periodic attacks of acute anxiety. Associated signs and symptoms include irritability, insomnia, dizziness, and mild headache. The anxiety is usually most pronounced in situations demanding attention, judgment, or comprehension.
Posttraumatic stress disorder
Posttraumatic stress disorder occurs in patients who have experienced an extreme traumatic event. It produces chronic anxiety of varying severity and is accompanied by intrusive, vivid memories and thoughts of the traumatic event. The patient also relives the event in dreams and nightmares. Insomnia, depression, and feelings of numbness and detachment are common.
Pulmonary edema
With pulmonary edema, acute anxiety occurs with dyspnea, orthopnea, cough with frothy sputum, tachycardia, tachypnea, crackles, ventricular gallop, hypotension, and thready pulse. The patient’s skin may be cool, clammy, and cyanotic.
Pulmonary embolism
Hypoxia resulting from a pulmonary embolus may lead to acute anxiety and restlessness. The patient may also experience dyspnea, tachypnea, chest pain, tachycardia, blood-tinged sputum, and low-grade fever.
Somatoform disorder
Somatoform disorder, which usually begins in young adulthood, is characterized by anxiety and multiple somatic complaints that can’t be explained physiologically. The symptoms aren’t produced intentionally but are severe enough to significantly impair functioning. Pain disorder, conversion disorder, and hypochondriasis are examples of a somatoform disorder.
Other causes
Drugs
Many drugs cause anxiety, especially sympathomimetics and central nervous system stimulants. In addition, many antidepressants may cause paradoxical anxiety.
Special considerations
Supportive care can help relieve anxiety. Provide a calm, quiet atmosphere and make the patient comfortable. Encourage him to express his feelings and concerns freely. If it helps, take a short walk with him while you’re talking. Or, try anxiety-reducing measures, such as distraction, relaxation techniques, or biofeedback.
Pediatric pointers
Anxiety in children usually results from painful physical illness or inadequate oxygenation. Its autonomic signs tend to be more common and dramatic than in adults.
Geriatric pointers
In elderly patients, distractions from the patient’s ritualistic activity may provoke anxiety or agitation.
Patient counseling
Teach the patient relaxation techniques and practice them with him. Encourage the patient to verbalize his anxiety and listen to him attentively. Help the patient identify and explore coping mechanisms that he used in the past. Work with the patient to identify stressors and guide him in effective coping skills.
