Subjective Data— Health History Questions
Cough Shortness of breath Chest pain with breathing History of respiratory infections Smoking history Environmental exposure Self-care behaviors Cough. Do you have a cough? When did it start? Gradual or sudden? Shortness of breath. Have you ever had any shortness of breath or hard-breathing spells? What brings it on? How severe is it? How long does it last? Chest pain with breathing. Do you have any chest pain with breathing? Please point to the exact location. Past history of respiratory infections. Do you have any past history of breathing trouble or lung diseases like bronchitis, emphysema, asthma, pneumonia? Smoking history. Do you smoke cigarettes or cigars? At what age did you start? How many packs per day do you smoke now? For how long? Environmental exposure. Are there any environmental conditions that may affect your breathing? Where do you work? At a factory, chemical plant, coal mine, farming, outdoors in a heavy traffic area? Self-care behaviors. Last tuberculosis skin test, chest x-ray study, pneumonia or influenza immunization?

Objective Data—The Physical Exam
Preparation Position Draping Timing during a complete examination Cleaning stethoscope endpiece Equipment needed Stethoscope Small ruler marked in centimeters Marking pen Alcohol swab
16
Objective Data—The Physical Exam (cont.)
Posterior Chest—Inspect Thoracic cage Shape and configuration of chest wall Anteroposterior/transverse diameter Position of person Skin color and condition
17
Objective Data—The Physical Exam (cont.)
Posterior Chest—Palpate Symmetric expansion Tactile (or vocal) fremitus Technique Factors that affect normal intensity of tactile fremitus Palpate the entire chest wall Posterior Chest—Percuss Predominant note over lung fields Diaphragmatic excursion
18
Objective Data—The Physical Exam (cont.)
Posterior Chest—Auscultate Breath sounds Technique Bronchial breath sounds—characteristics Bronchovesicular breath sounds—characteristics Vesicular breath sounds—characteristics Adventitious sounds Crackles Wheeze Atelectatic crackles Voice sounds Bronchophony Egophony Whispered pectoriloquy
19
Objective Data—The Physical Exam (cont.)
Anterior Chest—Inspect Shape and configuration of chest wall Facial expression Level of consciousness Skin color and condition Quality of respirations Rib interspaces Accessory muscles
20
Objective Data—The Physical Exam (cont.)
Anterior Chest—Palpate Symmetric chest expansion Tactile fremitus Palpate the anterior chest wall Anterior Chest—Percuss Predominant note over lung fields Borders of cardiac dullness
21
Objective Data—The Physical Exam (cont.)
Anterior Chest—Auscultate Breath sounds Abnormal breath sounds Adventitious sounds
22
Objective Data—The Physical Exam (cont.)
Measurement of pulmonary function status Forced expiratory time Pulse oximeter 6-Minute distance walk Edition Change: 12-minute walk is changed to 6-minute walk. Examiner should stop the patient if extreme breathlessness is observed, if the patient’s O2 saturation falls below 85%. Patient who covers 300 m or more is more likely to participate in ADLs.
