Conduct a focused history and examination assuming the role of a client with a respiratory symptom. Gather data on the presenting problem including symptoms such as cough, shortness of breath, chest pain with breathing, and other relevant manifestations. Document the patient’s history, including health status, medications, past medical and surgical history, family history, social habits, immunizations, and allergies. Perform a thorough physical examination, inspecting the client's general appearance, posture, respirations, skin, and nails. Examine posterior and anterior thorax for shape, symmetry, muscle development, and chest dimensions. Auscultate breath sounds at appropriate sites, and perform palpation for tenderness, bulges, symmetry, thoracic expansion, and tactile fremitus. If advanced practice, include percussion for tone and diaphragmatic excursion and assess vocal resonance. Palpate the trachea for position and review findings to identify potential nursing diagnoses and collaborative problems.

The assessment of a patient with respiratory complaints involves a comprehensive approach that encapsulates both detailed history-taking and meticulous physical examination. This process is vital for identifying the underlying etiology of respiratory symptoms and devising an effective care plan. The initial step entails gathering relevant subjective data, including the patient's chief complaints, their onset, duration, progression, and factors that influence their symptoms. For example, a patient presenting with shortness of breath necessitates understanding its onset—whether sudden or gradual—and associated features such as cough, chest pain, or wheezing. Additionally, assessing the patient's occupational exposures, smoking history, previous respiratory illnesses, and immunization status provides context crucial for diagnosis.

The patient history should also encompass past medical and surgical histories, which may include prior lung infections, surgeries such as thoracotomies, or chronic illnesses like asthma or COPD. Family history offers insight into potential genetic predispositions to respiratory diseases and may highlight hereditary conditions such as cystic fibrosis. Social history, including smoking, alcohol consumption, and environmental exposures, further informs the clinician’s assessment. Allergies and reactions should also be documented, especially if hypersensitivity is suspected as a cause of respiratory symptoms.

Following a comprehensive history, a thorough physical examination is essential. Inspection involves observing the client’s overall appearance, posture, respiratory effort, and skin and nail coloration. Changes such as cyanosis may indicate hypoxia. Respiratory rate and pattern should be noted, including depth and rhythm. During palpation, the examiner assesses for tenderness, swelling, or deformities of the thoracic muscles and chest wall. Tactile fremitus is evaluated by palpating the chest while the patient states a phrase to transmit vibrations, aiding in identifying areas of consolidation or fluid.

The examination of the posterior thorax involves inspecting for shape, symmetry, and muscle development, as well as auscultating breath sounds across the lung fields to detect abnormalities such as wheezes, crackles, or diminished sounds. The anterior thorax is similarly examined, with additional assessment of the shape, symmetry, and the anteroposterior to lateral diameter ratio—commonly known as the "barrel chest" in COPD. Palpation here includes checking for tracheal position and thoracic expansion. Advanced techniques such as percussion can distinguish between air-filled and fluid-filled areas, assess diaphragmatic movement, and identify areas of abnormality. Vocal fremitus and resonance are also evaluated to gather comprehensive data.

Integrating the findings from history and physical examinations allows the clinician to formulate appropriate nursing diagnoses such as impaired gas exchange, ineffective airway clearance, or risk of infection. Addressing these findings collaboratively supports targeted interventions, patient education, and ongoing management in respiratory health.
