Study Notes

BCCNM LPN Scope of Practice

Restricted activities that do not require an order include compounding, dispensing, or administering a drug specified in Schedule I or II of the Drug Schedules Regulation for the purpose of treating respiratory distress in a known asthmatic.

Respiratory System Review

Age-related changes in the respiratory system include:
- Decreased elastic recoil
- Decreased chest wall compliance
- Decreased anteroposterior diameter
- Decreased functioning alveoli
- Decreased response to hypoxemia and hypercapnia
- Decreased cough force
- Decreased alveolar macrophage function
Structures and functions of the respiratory system include:
- Respiratory airways
- Alveoli (functional units)
- Mucus covering the alveoli prevents gas exchange

Chronic Obstructive Pulmonary Disease (COPD)

Definition: an umbrella term for chronic bronchitis and emphysema
Causes: cigarette smoking, occupational chemicals and dust, infections, and heredity
Characteristics:
- Airway obstruction
- Inflammation
- Mucus buildup
- Narrowing or clogging of airways
Management:
- Establishment of a confirmed diagnosis
- Thorough health history
- Pulmonary function studies
- Limited exposure to triggers
- Education of patients
- Collaborative practice
  - Smoking cessation
  - Appropriate pharmacotherapy
  - Oxygen therapy
- Continuous assessment and monitoring of control and severity
- Implementation of a goal planning written action plan
- Ensuring regular follow-up

Pneumonia

Definition: acute lower respiratory infection
Types:
- Community-acquired pneumonia (CAP)
- Hospital-acquired pneumonia (HAP)
- Fungal pneumonia
- Aspiration pneumonia
Assessment data:
- Fever
- Rapid pulse rate
- Shortness of breath (SOB)
- Chest pain that increases with deep inspiration
- Productive cough with yellow/green sputum
Treatment:
- Antibiotics for bacterial infections
- Antipyretics for fever
- Expectorants to loosen mucus
- Nursing interventions:
  - Pushing fluids
  - Providing acceptable nutrition
  - Rest
  - Monitoring need for oxygen
Prevention:
- Vaccination (Pneumovax) for the elderly
