CHAPTER 18: Management of Patients with Upper Respiratory Tract Disorders
General Overview
Definition: Upper respiratory tract disorders encompass a range of conditions, from minor acute infections to life-threatening emergencies.
Objective: This review aims to furnish nursing students and practicing nurses with evidence-based assessment strategies, management principles, and tools for patient education, ensuring safe and effective care across various healthcare venues.
Management of Patients With Upper Respiratory Infections (URIs)
Epidemiology
URIs are the predominant cause of illness, healthcare consultations, and absences from work and school in the United States.
Impact: Millions of individuals across all age demographics are affected annually.
Severity Spectrum
The presentations of URIs range from minor and self-limiting illnesses to severe, life-threatening complications that may necessitate hospitalization and urgent interventions.
Care Settings
Most URIs are managed in community healthcare settings such as:
Physician offices
Urgent care clinics
Long-term care facilities
Home with guided self-care
Clinical Priorities
The prompt identification of symptoms combined with timely interventions is crucial in preventing unnecessary complications.
Patient education should focus on prevention strategies and promoting health.
Special Consideration: Older adults may exhibit atypical symptoms and are at a higher risk for complications (Refer to Chart 18-1).
Clinical Knowledge Check
Question #1: True or False? "The common cold refers to an infectious, chronic inflammation of the mucous membranes of the nasal cavity requiring hospitalization and treatment with IV antibiotics."
Consider the defining characteristics of the common cold, including its onset, duration, management settings, and typical treatment approaches.
CLINICAL FOCUS: Epistaxis (Nosebleeds)
Clinical Overview
Definition: Epistaxis refers to hemorrhage from the nasal cavity.
Common Site: The anterior nasal septum, known as Kiesselbach's plexus, is the primary site for bleeding due to its rich vascular supply and superficial position.
Severity: Episodes can vary from minor self-limiting instances to emergencies that may compromise the airway or result in significant blood loss.
Risk Factors
Hypertension and anticoagulant therapy
Nasal trauma
Dry environmental conditions
Nasal polyps
Coagulopathies
Critical Considerations
Immediate assessment of airway patency is crucial.
Monitor for signs of hypovolemia.
Identify any underlying bleeding disorders.
Evaluate the complete medication history, especially regarding anticoagulants.
Medical Management of Epistaxis
Conservative Measures
Position: Maintain an upright posture.
Technique: Pinch the nose for 5–10 minutes.
Interventions
Cauterization: Utilizing silver nitrate or electrocautery if necessary.
Initial Assessment: Identify the cause and the precise bleeding site.
Nasal Packing: Use gauze or a balloon catheter, kept in for 3–4 days as needed.
Antibiotic prophylaxis should be initiated with nasal packing to prevent toxic shock syndrome.
Control of Epistaxis
Nasal Packing Techniques
Anterior Nasal Packing: Layer petroleum-impregnated gauze or absorbable materials into the anterior nasal cavity to provide pressure on bleeding vessels. Packing should remain for 2–3 days.
Balloon Catheter Method: Involves inflating a double-balloon catheter—first the posterior balloon in the nasopharynx, followed by the anterior balloon in the nasal cavity for effective tamponade and easier removal.
Nursing Alert: Continuous pulse oximetry is critical as nasal packing can obstruct the airway and provoke a vasovagal response. Nasal packing should never be removed without a provider’s order and the availability of emergency equipment at bedside.
Nursing Management of Epistaxis
Priority Assessment
Conduct an immediate assessment of airway patency, breathing adequacy, and circulation status.
Position the patient upright to minimize aspiration risk.
Hemodynamic Monitoring
Frequently obtain vital signs and institute cardiac monitoring alongside continuous pulse oximetry in cases of significant bleeding or hemodynamic instability.
Anxiety Reduction
Offer calm reassurance and clear explanations to reduce the stress response related to epistaxis, which can be a frightening experience.
Prevention Strategies
Advise avoiding nasal trauma, such as picking the nose, and encourage maintaining optimal humidity (30-50% in a living environment).
Suggest refraining from blowforcefully blowing the nose, limit the consumption of spicy foods, alcohol, and tobacco, and postpone any strenuous exercises for 7-10 days.
Home Management
Recommend using saline nasal spray to prevent dryness, applying the pinching technique if bleeding recurs, and seeking immediate care if bleeding persists beyond 15 minutes, or at any signs of infection or fever.
Spectrum of Upper Respiratory Infections
Types of Infections
Rhinitis & Rhinosinusitis: Involves inflammation of nasal mucosa and paranasal sinuses. Classified as acute, chronic, bacterial, and viral (Refer to Charts 18-2 & 18-3).
Pharyngitis: Refers to inflammation of the pharynx, which can be acute or chronic, caused by viral, bacterial (Group A Streptococcus), or environmental irritants.
Tonsillitis & Adenoiditis: Inflammation of palatine tonsils and adenoids, prevalent in children, which may necessitate surgical intervention if recurrent.
Peritonsillar Abscess: A purulent collection between the tonsillar capsule and pharyngeal muscles, requiring urgent drainage due to risk of severe complications.
Laryngitis: Causes inflammation of the larynx leading to voice loss or hoarseness; can be acute (primarily viral) or chronic (due to vocal strain, GERD, smoking).
Rhinitis and Rhinosinusitis: Clinical Features
Pathophysiology: Inflammation of nasal mucosa; rhinosinusitis extends involvement to paranasal sinuses which can become obstructed leading to bacterial overgrowth.
Clinical Manifestations: Includes:
Nasal congestion and discharge (either clear or purulent)
Facial pain/pressure over the affected sinuses
Headache, exacerbated when bending forward
Postnasal drip and hyposmia
Low-grade fever
Dental pain in cases of maxillary sinusitis
Diagnostic Criteria: Acute bacterial rhinosinusitis is suspected when symptoms persist beyond 10 days or worsen after initial improvement, with CT imaging indicated for chronic or complicated cases.
Pharyngitis: Assessment and Recognition
Clinical Presentation: Common symptoms include throat pain, odynophagia, and pharyngeal erythema. Viral pharyngitis is the most frequent type, typically presenting alongside rhinorrhea, cough, and conjunctivitis.
Distinguishing Features:
Viral: Gradual onset, cold symptoms, and low-grade fever.
Bacterial (Strep): Sudden onset with high fever, tender cervical nodes, tonsillar exudates, and absence of cough.
Centor Criteria: To evaluate the probability of Strep throat, a rapid strep test or throat culture is essential:
Presence of tonsillar exudate.
Tender anterior cervical lymphadenopathy.
Fever history.
Absence of cough.
Potential Complications of Upper Respiratory Infections
While most URIs resolve without sequelae, vigilance for serious complications is necessary:
Life-Threatening Emergencies:
Airway obstruction, e.g., due to epiglottitis or severe edema.
Hemorrhage, such as post-operative bleeding or severe epistaxis.
Sepsis, which may arise from systemic bacterial infections accompanied by hemodynamic compromise.
Neurological Complications:
Meningitis presenting with nuchal rigidity and altered mental status.
Acute otitis media, characterized by middle ear infection and otalgia.
Cellulitis, a spreading soft tissue infection.
Aphonia leading to complete voice loss.
Dysphagia, which heightens aspiration risk.
Treatment-Related Issues:
Rhinitis medicamentosa is caused by rebound congestion from overuse of topical decongestants.
Trismus refers to jaw muscle spasm that limits mouth opening.
Tracheostomal stenosis is defined as the narrowing of the surgical airway opening.
Clinical Knowledge Check
Question #2: What should the nurse recommend a patient with pharyngitis avoid?
Electronic nicotine delivery systems (vaping)
Exposure to Extreme Heat (high-temperature environments)
Secondhand Smoke (passive tobacco smoke exposure)
A and C (ENDS use and secondhand smoke)
Answer to Question #2
Correct Answer: D. A and C
Rationale: Patients with chronic pharyngitis should avoid alcohol, tobacco, secondhand smoke, electronically delivered nicotine systems (ENDS), cold environments, and environmental pollutants, as these irritants exacerbate pharyngeal inflammation and prolong healing.
Protective Measures: Patients may use disposable face masks to filter particulate matter such as dust and mold spores when exposure is unavoidable.
Comfort Measures: Encourage adequate oral hydration to help thin secretions and soothe irritated mucous membranes. Recommend throat lozenges or warm saline gargles (¼ tsp of salt in 8 oz of warm water) every 2–4 hours for discomfort relief.
Patient Teaching Tip: Warm liquids, such as herbal tea with honey, provide symptomatic relief while promoting hydration; acidic beverages should be avoided as they can intensify irritation.
Comprehensive Assessment of the Patient with URI
Health History
Document the onset, duration, and progression of symptoms; past respiratory infections; chronic conditions; immunization status; and recent exposure history.
Symptom Analysis
Evaluate for headache, cough, hoarseness, fever, nasal stuffiness, malaise, and fatigue, assessing severity and impact on daily functioning.
Allergy Assessment
Identify medication allergies, particularly to antibiotics, as well as environmental or seasonal allergies that could complicate symptoms.
Physical Examination
Systematically inspect the nasal cavity and oropharynx; palpate cervical, submandibular, and anterior/posterior cervical lymph nodes bilaterally; note size, consistency, mobility, and tenderness.
Planning and Goals for the Patient with URI
Airway Management
Ensure a patent airway and reduce aspiration risks through appropriate positioning and effective secretion management.
Pain Management
Aim for adequate pain control to foster comfort, facilitate rest, and enable proper nutritional intake.
Effective Communication
Establish alternative communication methods when speech is impaired by hoarseness or due to surgical interventions.
Normal Hydration
Maintain appropriate fluid balance to thin secretions and promote mucociliary clearance.
Patient Education
Provide comprehensive education on URI prevention, self-care measures, and warning signs of complications that necessitate medical attention.
Evidence-Based Nursing Interventions for URI Management
Respiratory Support
Positioning: Elevate the head of the bed (HOB) to 30–45° to encourage drainage and reduce aspiration risks.
Humidification: Utilize room vaporizers or steam inhalation to assist in loosening secretions.
Hydration: Encourage oral intake of 2–3 liters of fluids daily, barring contraindications.
Symptom Management
Using an ice collar can reduce inflammation and control bleeding (epistaxis); hot packs may be applied over sinuses to alleviate congestion and promote drainage.
Saline gargles should be recommended every 2–4 hours for throat relief.
Pharmacological Interventions
Analgesics: Use acetaminophen or NSAIDs to manage pain and fever.
Topical Anesthetics: Administer benzocaine throat sprays or lozenges for localized relief.
Communication Support
For patients with severe laryngitis or post-laryngectomy, establish alternative communication methods such as writing aids, communication boards, or electronic devices.
Monitoring and Prevention
Vigilantly monitor for respiratory distress, high fever, or altered mental status while promoting adequate rest to support immune function. Ensure that patients complete prescribed antibiotic courses.
Evaluation of Patient Outcomes
Airway Patency: Confirm a patent airway with clear bilateral breath sounds, SpO₂ > 95% on room air, and no respiratory distress.
Pain Control: Aim for pain levels ≤3/10, allowing patients to swallow, rest comfortably, and engage in daily activities.
Communication Ability: Facilitate effective communication of needs using established alternative methods when verbal communication is hampered.
Hydration Status: Evaluate for moist mucous membranes, elastic skin turgor, balanced intake/output (I&O), and urine specific gravity within normal limits.
Symptom Resolution: Assess return to baseline functional status alongside the resolution of signs and symptoms, with no complications present.
Documentation: Record the achievement of goals, patient's responses to interventions, any deviations from expected outcomes, and the patient’s comprehension of discharge instructions and required follow-up plans.
Patient and Family Education for URI Prevention
Hand Hygiene
Handwashing with soap and water for at least 20 seconds prior to eating, post-restroom use, and following contact with ill individuals is critical. Alcohol-based sanitizers (≥60% alcohol) serve as a good alternative when soap and water are inaccessible.
Antibiotic Stewardship
Patients must complete the full course of prescribed antibiotics, even if they experience symptom improvement; early discontinuation fosters antibiotic resistance and elevates the risk of recurrence.
Annual Influenza Vaccination
It is strongly recommended that high-risk populations (e.g., adults over 65 years, pregnant women, healthcare workers, individuals with chronic illnesses, and immunocompromised patients) receive the annual flu vaccine.
When to Seek Medical Care
Advise contacting healthcare providers if fever exceeds 101°F, persists beyond 3 days, or accompanies difficulty breathing, severe sore throat lasting more than 2 days, worsening symptoms, chest pain, or facial swelling.
Influenza: Epidemiology and Clinical Management
Epidemiology and Transmission
Seasonal influenza primarily occurs in temperate climates during fall and winter.
Adults remain contagious from 24 hours prior to symptom onset through 5 days afterward; immunocompromised individuals may shed the virus for a more extended duration.
Clinical Manifestations
Key symptoms include:
Sudden high fever (101–104°F)
Severe myalgias and chills
Profound fatigue and dry cough
Headaches
GI symptoms (more prevalent in children)
Potential hypoxia in severe cases.
Antiviral Therapy
Neuraminidase inhibitors: Medications like oseltamivir and zanamivir are most effective if administered within 24–48 hours of symptom onset, reducing duration and severity, especially in high-risk patients.
Infection Control
Implement droplet and contact precautions for hospitalized patients, including those with H1N1; surgical masks for infected patients; appropriate personal protective equipment (PPE) for healthcare workers.
Supportive Care
Provide warm saline gargles for throat discomfort; encourage rest and limit activities; maintain hydration through clear fluids; diligently monitor respiratory status; and evaluate for secondary bacterial pneumonia.
CHAPTER 18: INFECTIOUS DISEASE - Tuberculosis: Pathophysiology and Transmission
Pathophysiology
Tuberculosis (TB) is caused by Mycobacterium tuberculosis, which spreads via airborne droplet nuclei when infected individuals cough, sneeze, speak, or sing; although primarily pulmonary, TB can disseminate to various sites such as the brain, kidneys, spine, and lymph nodes (extrapulmonary TB).
Latent vs. Active TB
LTBI (Latent Tuberculosis Infection): Asymptomatic and non-contagious but carries a 5% to 10% lifetime risk of reactivation.
Active TB: The immune system cannot contain the bacteria, with the highest risk of developing the disease within the first 2 years post-infection, particularly among immunocompromised individuals.
Transmission Dynamics
Transmission risk diminishes markedly after 2 to 3 weeks of appropriate antitubercular therapy; close contacts must undergo screening and possibly prophylactic treatments.
Screening and Risk Factors
Annual screening is essential for high-risk groups that include individuals with:
Recent travel to TB-endemic regions
History of homelessness or incarceration
Exposure to TB through healthcare work
Living in poverty, crowded conditions, or having limited healthcare access.
Tuberculosis: Clinical Manifestations and Diagnostics
Cardinal Signs and Symptoms
Persistent cough lasting longer than 3 weeks.
Hemoptysis (blood-tinged sputum).
Drenching night sweats.
Unintentional weight loss and anorexia.
Profound weakness and fatigue.
Pleuritic chest pain.
Low-grade afternoon fever.
Critical Diagnostics
Collect three early morning sputum specimens on consecutive days—N-95 respirators should be worn during collection.
AFB Smear and Culture: Confirm diagnosis through laboratory results.
NAAT (Nucleic Acid Amplification Test): Detects M. tuberculosis in respiratory specimens, providing results within 2 hours and possesses high sensitivity and specificity.
IGRA (Interferon-Gamma Release Assays): produces results within 24–36 hours; preferable for BCG-vaccinated individuals due to fewer false positives than the tuberculin skin test.
Tuberculin Skin Test (Mantoux): An intradermal injection of PPD; read within 48–72 hours with induration of ≥10 mm considered positive for most, and ≥5 mm for immunocompromised patients.
Nursing Care for Tuberculosis Patients
Airborne Precautions
Patient isolation should occur in a negative airflow room with at least 12 air exchanges per hour; maintain a closed-door policy.
Precautions should commence immediately with any suspicion of TB.
Personal Protective Equipment (PPE)
Healthcare workers must use N-95 respirators equipped with HEPA filtration, with annual fit testing mandated; standard surgical masks do not offer sufficient protection.
Medication Regimen
The standard treatment involves a four-drug regimen of INH (Isoniazid) + RIF (Rifampin) + PZA (Pyrazinamide) + EMB (Ethambutol) taken daily in the morning on an empty stomach to maximize absorption.
Critical Compliance Issue: TB medications require a continuous course lasting from 6 to 12 months. Stopping medication prematurely can lead to multi-drug resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB). Directly observed therapy (DOT) may be considered for high-risk patients; despite feeling better within 2–3 weeks, full course completion is vital.
SURGICAL MANAGEMENT
Comprehensive Assessment for Laryngectomy Patients
A laryngectomy permanently impacts voice production, breathing, and swallowing, necessitating comprehensive assessment along with patient and family preparation.
Health History
Evaluate for comorbidities, smoking history (pack-years), alcohol use, previous head/neck surgeries or radiation, and current medications.
Physical Assessment
Conduct head and neck examinations, assessing tumor size and location, lymph node involvement, cranial nerve functions, baseline airway, voice quality, and swallowing capabilities.
Psychosocial Assessment
Address emotional readiness for permanent voice loss, body image concerns, depression or anxiety, and spiritual resources. Discuss realistic expectations with the patient.
Nutritional Status
Track BMI, weight trends, serum albumin, glucose, and electrolyte levels as malnutrition can result in unfavorable surgical outcomes; preoperative optimization may be necessary.
Communication Baseline Assessments
Determine factors such as literacy, hearing, and vision that impact postoperative communication. Collaboration with speech pathology early in the process is critical to facilitate future communication strategies.
Support Systems
Evaluate coping skills, family support levels, and caregiver capabilities in assisting with complicated postoperative care, including tracheostomy management.
Collaborative Problems and Potential Complications
Priority Surveillance
Watch for:
Respiratory Distress: An immediate life threat, potentially necessitating emergency tracheostomy revision.
Hemorrhage: Look for increased drainage, tachycardia, hypotension, and restlessness as indicators.
Infection: Symptoms include fever, purulent drainage, erythema, and elevated white blood cell counts; those with oral/pharyngeal flora are notably at high risk.
Wound Breakdown: Highest risk period is post-operative days 5–7.
Aspiration: Silent aspiration poses particular dangers due to the absence of a cough reflex.
Stenosis: Can be avoided through appropriate tube sizing and meticulous stoma hygiene.
Nursing Interventions for Laryngectomy Patients
Preoperative Teaching: Utilize visual aids, anatomical models, and written materials suitable for the patient’s literacy level; engage family members in the teaching sessions.
Airway Management Excellence: Initially suction every 1–2 hours; maintain continuous humidification; monitor SpO₂ continuously and evaluate breath sounds every 2–4 hours.
Alternative Communication Support: Immediately establish systems for writing and communication using boards or applications; collaborate with speech-language pathology for voice restoration such as tracheoesophageal puncture (TEP), electrolarynx, or esophageal speech.
Nutritional Optimization: Begin with tube feeding (NG or gastrostomy) and progressively transition to oral feeding as swallowing function allows, under the guidance of speech-language pathology. Continuously monitor weight and laboratory values weekly.
Self-Care and Home Preparation: Initiate instruction on stoma care, tracheostomy tube changes, and emergency procedures prior to discharge, ensuring competency in return demonstrations.
Clinical Knowledge Check
Question #3: What is a priority education component for a patient scheduled for a total laryngectomy?
Clarifying Misconceptions
Discussing Effects on Speech
Explaining Communication Methods
All of the Above
Answer to Question #3
Correct Answer: D. All of the Above
Rationale: Patients facing a total laryngectomy often experience significant anxiety regarding the permanent loss of their voice. This profound, life-altering change necessitates in-depth preoperative psychological preparation and education on all dimensions of their care.
Critical Teaching Components
Clarifying Misconceptions: The nurse must identify and correct any inaccurate beliefs to lower anxiety levels and set realistic expectations about recovery and lifestyle adjustments post-surgery.
Discussing Voice Loss: It is essential to reinforce that the natural voice will be lost permanently, avoiding euphemisms that may create false hope for recovery.
Communication Alternatives:
Immediate: Writing, communication boards, and gestural methods.
Short-Term: Use of an electrolarynx (artificial larynx).
Long-Term: TEP and esophageal speech are options for ongoing communication.
Best Practice: Involving family members in all preoperative education and considering meetings with a laryngectomy support group member who has adapted successfully to voice loss can provide emotional and practical support to the patient.
