Study Notes

Pulmonary Edema

Most commonly caused by increased microvascular hydrostatic pressure, associated with left-sided or bilateral cardiac failure (cardiogenic edema).
Can also occur from hypervolemia (excessive fluid therapy), which may be related to fluid overload even without excess fluid in the body.
Noncardiogenic pulmonary edema can result from bronchospasm, increased mucus production, ineffective cough, and possible bronchopulmonary infection.
Characteristics:
- Costophrenic angle obliterated by fluid
- All of the lungs are covered with fluid
- Wet sounds
- Shifting of fluid
- Always acute

Oral Anticoagulation (WARFARIN)

Used for follow-up anticoagulant therapy after heparin therapy has been established
Interrupts the coagulation mechanism by interfering with the vitamin K-dependent synthesis of prothrombin and factors VII, IX, and X
Dosage is controlled by monitoring serial tests of prothrombin time.
Desired prothrombin time is 1.2 to 1.5 times the control value.
Monitor activated partial thromboplastin time (aPTT) every 3 days

Oral Anticoagulation (Novel Oral Anticoagulant [NOAC])

Has more advantages over warfarin, including:
- More predictable pharmacokinetics
- No need for routine aPTT monitoring
- Rapid onset of action
- Shorter half-life
- Fewer food and drug interactions

Thrombolytic Enzymes

Thrombolytic agents, such as urokinase and streptokinase, may be used in patients with massive pulmonary embolism.
Effective in lysing recently formed thrombi, improving circulatory and hemodynamic status.
Administered intravenously as a loading dose followed by a constant infusion.
Newer clot-specific thrombolytics include tissue plasminogen activator (t-PA), acylated plasminogen streptokinase activator complex, and single-chain urokinase.
- Activate plasminogen only within the thrombus itself, minimizing occurrences of generalized fibrinolysis and subsequent bleeding.

Nursing Diagnoses:

Respiratory Distress
- Impaired gas exchange r/t increased alveolar-capillary permeability, interstitial edema, and decreased lung compliance.
- Chronic pulmonary obstruction (V/Q abnormalities).
Ineffective Breathing Pattern
- Increased alveolar dead space
- Possible changes in lung mechanics.

Pulmonary Embolism Nursing Diagnoses

Ineffective Breathing Pattern:
- Increase in alveolar dead space
- Possible changes in lung mechanics
Altered Tissue Perfusion:
- Decreased blood circulation in the lungs
Pain (Pleuritic)
- Congestion
- Possible pleural effusion
- Possible lung infarction
Anxiety:
- Dyspnea
- Pain
- Seriousness of condition
Knowledge Deficit: Current condition and long-term treatment

Acute Pulmonary Edema Nursing Diagnoses

Impaired Gas Exchange:
- Excess fluid in the lungs.
- Acute pulmonary obstruction resulting in reduced ventilation (V/Q mismatch).
Ineffective Breathing Pattern:
- Airflow limitation brought about by fluid accumulation.
Anxiety:
- Sensation of suffocation and fear

Pneumothorax Nursing Diagnoses

Acute Pain:
- Presence of air in the thoracic cavity
- Chest injury
Impaired Gas Exchange:
- Ventilation and perfusion imbalance (V/Q mismatch).
- Reduced functional lung tissue due to compression
Ineffective Breathing Pattern:
- Limited or asymmetrical lung expansion
- Airway compression brought about by mediastinal shift or tracheal deviation

Other Nursing Diagnoses Associated with Pulmonary Issues

Altered Nutrition (less than body requirements):
- Increased work of breathing
- Air swallowing
- Medication effects
- Impaired gastrointestinal function (bloating, reflux)
- Depression
Activity Intolerance: Compromised pulmonary function resulting in shortness of breath and fatigue.
Sleep Pattern Disturbance: Hypoxemia and hypercapnia
Impaired Individual Coping: Stress of living with chronic disease
Risk for Aspiration: Breathing difficulties.
Knowledge Deficit: How to live with chronic obstructive pulmonary disease.
Anxiety: Specify level (mild, moderate, severe, panic).
