Module 4 Student Notetaking Guide
• Nurses are often the first to detect signs of upper respiratory dysfunction in the outpatient
setting, inpatient unit, or long-term care facility. A thorough understanding of the upper
airway structures and the ability to identify early symptoms of respiratory compromise
allow for timely interventions that can prevent escalation to more serious lower respiratory
conditions.
• Nurses are vigilant guardians of one of the body’s most essential life-support systems, from
recognizing hoarseness and congestion to distinguishing rhinitis from pharyngitis.
Socratic Question: What clinical consequences might occur if early signs of upper respiratory
tract disorders are unrecognized during routine nursing assessments?
• Delayed recognition could lead to airway obstruction, infection spread, or progression to
lower respiratory tract infection, increasing the risk of hospitalization and complications.
Common Upper Respiratory Disorders and Their Assessment Findings
• Understanding the structures and functions of the upper respiratory tract lays the
foundation for recognizing and interpreting assessment findings. Nurses must be prepared
to differentiate among various disorders that share similar symptoms but require distinct
interventions.
Upper Respiratory Tract Structures and Their Functions
• The upper airway includes the nose, paranasal sinuses, nasal cavities, pharynx, tonsils,
larynx, and trachea. Each of these structures contributes to the warming, filtering, and
humidifying of inspired air—a critical process that protects the delicate tissues of the lower
respiratory tract.
, 2
Nose and Nasal Cavities
• Filter and humidify inspired air via the respiratory mucosa—a vascular, ciliated
membrane that traps debris and organisms.
• The turbinate’s increased surface area enhances air contact and filtration.
Paranasal Sinuses
• Air-filled cavities (frontal, ethmoid, sphenoid, maxillary) that drain into the nasal
passages.
• Act as resonance chambers for speech; they are frequently affected by infection.
Pharynx and Tonsils
• The pharynx connects the nasal and oral cavities to the larynx and serves respiratory and
digestive functions.
• Tonsils and adenoids are lymphoid tissues that trap pathogens entering through the
mouth or nose.
Larynx
• Also known as the "voice box," it includes vocal cords and protects the lower airway via
the epiglottis.
• Facilitates coughing to expel irritants and is essential for phonation.
Trachea
• Connects the larynx to the bronchi and serves as a conduit for air to reach the lungs.
• Reinforced with C-shaped cartilage rings to maintain airway patency.
• These anatomical structures support ventilation and serve as the primary defense
against environmental hazards.
Common Upper Respiratory Disorders: Signs and Symptoms
• Nurses must differentiate among overlapping symptoms to accurately identify and respond
to common upper airway disorders.

Physical Assessment Findings in Upper Respiratory Disorders
• Assessment should include inspection, palpation, and auscultation of the head, neck, and
thorax. Nurses should be alert for the following:
• Nasal congestion: Swollen nasal passages are often associated with infection or allergic
rhinitis. May impair airflow.
• Throat erythema: Redness indicates inflammation and is commonly seen in pharyngitis or
tonsillitis.
• Voice hoarseness: Often associated with laryngitis or vocal cord strain; persistent
hoarseness may indicate laryngeal cancer.
• Stridor: A high-pitched, inspiratory sound heard during breathing - suggests upper airway
obstruction (e.g., croup, foreign body, laryngeal edema).
• Palpable lymphadenopathy: Tender, enlarged lymph nodes point to infection, particularly
in pharyngitis and tonsillitis.
Clinical Example: A 42-year-old male presents to the urgent care clinic with a 3-day history of
sore throat, dry cough, and progressive hoarseness. He reports no fever but admits to recent
yelling at a concert. A physical exam revealed mild erythema of the pharynx, normal tonsils, and
audible hoarseness. No lymphadenopathy is present. The nurse recognizes the likely diagnosis
