Management of Upper Respiratory Infections
A Community Health Nursing Perspective
Table of Contents
1. Introduction
Upper respiratory infections (URIs) are among the most common health issues encountered in community health nursing practice. These infections affect the upper respiratory tract, which includes the nose, sinuses, pharynx, larynx, and trachea. As community health nurses, understanding the proper respiratory infection management protocols is essential for providing effective care and preventing complications.
This educational resource provides comprehensive guidance on the assessment, diagnosis, treatment, and referral criteria for common upper respiratory conditions from a community health nursing perspective. The conditions covered include rhinitis, sinusitis, pharyngitis, laryngitis, and tonsillitis.

2. Standing Orders: Definition and Uses
Definition
Standing orders are written medical protocols that authorize healthcare professionals, such as nurses, to carry out specific assessments and interventions without direct physician supervision for certain conditions when specific criteria are met.
Key Components of Standing Orders
In community health nursing practice, standing orders for respiratory infection management typically include:
- Specific criteria that must be met before implementing the standing order
- Clear description of assessments to be performed
- Detailed interventions that may be implemented
- Parameters for when physician consultation or referral is required
- Documentation requirements
Benefits of Standing Orders
Standing orders offer several advantages in community health settings:
- Expedited care for patients with common conditions
- Efficient use of healthcare resources
- Standardization of care based on evidence-based practices
- Expanded scope of practice for nurses in primary care settings
- Improved access to care, especially in underserved areas
Legal Considerations
When implementing standing orders for respiratory infection management, nurses must:
- Ensure the standing orders are signed by an authorized prescriber
- Stay within the scope of practice defined by state nursing boards
- Implement orders exactly as written
- Document all assessments and interventions thoroughly
- Recognize when a situation exceeds the parameters of the standing order

3.1 Assessment Approach
A systematic approach to respiratory infection management begins with a thorough assessment:
RIPPAS Assessment Framework
A systematic approach to respiratory assessment:
- R Respiratory rate: Count for a full minute
- I Inspection: Observe for signs of respiratory distress
- P Palpation: Check for tenderness, swelling, crepitus
- P Percussion: Assess for abnormal sounds
- A Auscultation: Listen for abnormal breath sounds
- S Saturation: Measure oxygen levels
History Taking
Key elements to include in patient history for suspected upper respiratory infections:
- Onset, duration, and progression of symptoms
- Specific symptoms (congestion, sore throat, cough, fever)
- Exposure to sick contacts
- Previous episodes and treatments
- Vaccination history
- Comorbid conditions (asthma, COPD, immunocompromised status)
- Current medications
- Allergies
3.2 Diagnostic Methods
Several diagnostic methods are available for confirming specific upper respiratory infections:
| Diagnostic Method | Appropriate Conditions | Considerations for Community Settings |
|---|---|---|
| Throat Culture | Pharyngitis, Tonsillitis | Gold standard for bacterial pharyngitis; results take 24-48 hours |
| Rapid Strep Test | Pharyngitis, Tonsillitis | Results in minutes; negative results may require confirmation with culture |
| Nasal/Nasopharyngeal Swabs | Rhinitis, Sinusitis | Useful for viral identification; can be performed in community settings |
| Anterior Rhinoscopy | Rhinitis | Simple procedure to visualize nasal mucosa; requires proper lighting |
| Transillumination | Sinusitis | Simple screening tool for sinusitis; limited accuracy |
| Oxygen Saturation | All respiratory conditions | Quick, non-invasive assessment of respiratory status |
Clinical Pearl
In community settings, diagnosis of upper respiratory infections is often clinical, based on symptom patterns and physical examination findings. Reserve laboratory testing for cases where results would change management decisions, such as suspected bacterial infections that would benefit from antibiotics.
4. Common Upper Respiratory Conditions
Rhinitis
Definition
Inflammation of the nasal mucous membranes characterized by nasal congestion, rhinorrhea, sneezing, and nasal itching.
Types

- M Muscle use (accessory muscle use)
Emergency Response Steps
- Assess: Quickly evaluate airway, breathing, and circulation (ABC)
- Position: Place patient in high Fowler’s position (semi-sitting) if conscious
- Oxygen: Administer oxygen if available and indicated
- Monitor: Check vital signs, including oxygen saturation if possible
- Activate EMS: Call emergency services for signs of severe respiratory distress
Specific Emergency Scenarios
