Focused Exam Cough

Definition

A focused exam cough is a specific type of cough assessment that focuses on evaluating the characteristics of a patient’s cough, including its frequency, duration, quality, and associated symptoms.

The purpose of a focused exam cough is to gather detailed information about the cough in order to identify its underlying cause and guide appropriate treatment decisions.

Objective Data Collection

Objective data collection during a focused exam cough involves gathering specific observable signs and measurements to assess the patient’s condition. These data points provide valuable information about the cough’s characteristics, severity, and potential underlying causes.

The following are the key objective data points that should be collected during a focused exam cough:

Type of Cough

• Dry cough:A cough without mucus production.
• Productive cough:A cough that produces sputum (mucus).

Duration of Cough

• Acute cough:Less than 3 weeks.
• Subacute cough:3 to 8 weeks.
• Chronic cough:More than 8 weeks.

Frequency of Cough

• Occasional:Less than 5 coughs per hour.
• Frequent:5 to 15 coughs per hour.
• Constant:More than 15 coughs per hour.

Timing of Cough, Focused exam cough objective data

• Diurnal cough:Coughing occurs mainly during the day.
• Nocturnal cough:Coughing occurs mainly at night.
• Coughing up blood (hemoptysis):This is a serious symptom that requires immediate medical attention.

Character of Cough

• Barking cough:A harsh, dry cough that resembles the sound of a dog barking.
• Whooping cough:A cough that is characterized by a series of rapid, forceful coughs followed by a high-pitched whoop.
• Croupy cough:A hoarse, brassy cough that is caused by swelling in the larynx.

Associated Symptoms

• Fever:A temperature of 100.4°F (38°C) or higher.
• Shortness of breath:Difficulty breathing.
• Chest pain:Pain or discomfort in the chest.
• Wheezing:A whistling sound during breathing.

Physical Examination Findings

• Auscultation of the lungs:Listening to the lungs with a stethoscope to detect any abnormal sounds, such as wheezing, rales, or rhonchi.
• Percussion of the lungs:Tapping on the chest to assess the density of the lung tissue.
• Palpation of the chest:Feeling the chest to detect any tenderness or masses.

Methods and Procedures: Focused Exam Cough Objective Data

Performing a focused exam cough involves standardized methods and procedures to ensure accuracy and consistency in data collection. These methods encompass patient positioning, examiner technique, and appropriate equipment utilization.

Patient Positioning

Patient positioning is crucial for optimal cough assessment. The patient should be:

• Sitting upright with their back supported
• Arms resting comfortably on a table or in their lap
• Neck slightly flexed forward
• Mouth open slightly, and tongue resting on the floor of the mouth

Examiner Technique

The examiner should:

• Stand or sit facing the patient
• Instruct the patient to cough forcefully for 5-10 seconds
• Observe the patient’s cough and assess the following characteristics:
• Frequency
• Duration
• Volume
• Quality (e.g., wet, dry, barking, hacking)
• Associated symptoms (e.g., pain, hoarseness)

Equipment Utilization

In certain cases, additional equipment may be utilized during a focused exam cough, such as:

• Stethoscope: To auscultate the chest for adventitious sounds associated with coughing
• Spirometer: To measure lung function and assess the impact of coughing on respiratory parameters

Interpretation of Findings

The interpretation of objective data collected during a focused exam cough aids in determining the underlying cause and guiding appropriate patient care. Specific findings may suggest different etiologies, necessitating further evaluation and management.

Cough Characteristics

• Duration:Acute (less than 3 weeks), subacute (3-8 weeks), or chronic (more than 8 weeks) coughs have different implications.
• Timing:Daytime, nighttime, or both can indicate specific underlying conditions.
• Quality:Productive (with sputum) or non-productive (dry) coughs provide clues about the respiratory tract involvement.
• Severity:Mild, moderate, or severe coughs can assess the impact on daily activities and quality of life.
• Associated symptoms:Fever, shortness of breath, chest pain, or wheezing can suggest additional respiratory or systemic issues.

Auscultation Findings

• Clear lungs:No abnormal sounds indicate normal lung function.
• Wheezes:High-pitched whistling sounds suggest airway narrowing, commonly associated with asthma or COPD.
• Rales:Crackling or bubbling sounds indicate fluid or secretions in the airways or alveoli.
• Rhonchi:Low-pitched snoring sounds suggest airway narrowing due to mucus or secretions.
• Pleural friction rub:Grating or scratching sounds indicate inflammation of the pleura, often associated with pneumonia or pleurisy.

Percussion and Palpation Findings

• Hyperresonance:Increased lung resonance suggests emphysema or pneumothorax.
• Dullness:Decreased lung resonance indicates fluid or consolidation in the lungs.
• Tenderness:Pain or discomfort upon palpation may indicate pleuritis or chest wall inflammation.

Documentation

Accurate and comprehensive documentation is crucial in a focused exam cough to provide a clear and concise record of the patient’s condition, the examiner’s findings, and any interventions performed.

It ensures effective communication among healthcare professionals, supports decision-making, and facilitates continuity of care.

Sample Documentation Template

• Patient Information:Name, age, gender, medical history
• Chief Complaint:Cough
• History of Present Illness:Duration, characteristics, aggravating/relieving factors
• Physical Examination:
  • General:Appearance, vital signs
  • Respiratory:Auscultation, percussion, palpation
  • Other:Head, neck, chest, abdomen
• Assessment:Likely cause of cough (e.g., bronchitis, pneumonia)
• Plan:Treatment recommendations, follow-up instructions

Applications

A focused exam cough is a valuable tool for healthcare professionals in the clinical setting. It aids in the assessment of respiratory conditions and provides important information to guide diagnosis and management.

Through careful observation and analysis of cough characteristics, such as frequency, duration, quality, and associated symptoms, clinicians can gain insights into the underlying respiratory pathology.

Diagnosis

A focused exam cough assists in differentiating between various respiratory conditions, such as:

• Upper respiratory tract infections (e.g., common cold, sinusitis)
• Lower respiratory tract infections (e.g., bronchitis, pneumonia)
• Asthma
• Chronic obstructive pulmonary disease (COPD)
• Cardiac conditions (e.g., heart failure)

Management

By identifying the characteristics of the cough, healthcare professionals can tailor treatment plans accordingly:

• Cough suppressants for non-productive coughs
• Expectorants for productive coughs
• Bronchodilators for asthma and COPD
• Antibiotics for respiratory infections

Limitations

Focused exam cough is a valuable tool for assessing patients with cough, but it has certain limitations:

1. Limited Information: A focused exam cough provides limited information about the underlying cause of cough, as it focuses on the physical examination and patient history. Further diagnostic tests, such as imaging or laboratory studies, may be necessary to determine the specific cause.

2. Subjective Findings: Some aspects of the focused exam cough, such as the description of the cough, are subjective and may vary depending on the patient’s perception and reporting. This can lead to potential variability in the interpretation of findings.

3. Not Suitable for All Cases: A focused exam cough may not be appropriate or provide sufficient information in all cases. For example, in patients with severe respiratory distress, it may be necessary to perform a more comprehensive evaluation, including arterial blood gas analysis or chest X-ray, to assess the underlying cause.

Differential Diagnoses

Cough is a common symptom with various potential underlying causes. Based on the objective data collected during a focused exam, several differential diagnoses can be considered:

Upper Respiratory Tract Infections

• Rationale:Cough is a common symptom of upper respiratory tract infections (URTIs), such as the common cold, influenza, and sinusitis. Objective data may reveal nasal discharge, congestion, sore throat, or hoarseness.

Lower Respiratory Tract Infections

• Rationale:Cough can also be a symptom of lower respiratory tract infections (LRTIs), such as bronchitis, pneumonia, and tuberculosis. Objective data may reveal wheezing, crackles, or decreased breath sounds.

Asthma

• Rationale:Asthma is a chronic respiratory condition characterized by airway inflammation and narrowing. Objective data may reveal wheezing, coughing, and difficulty breathing, especially during exertion or exposure to triggers.

Chronic Obstructive Pulmonary Disease (COPD)

• Rationale:COPD is a progressive lung disease that causes airflow obstruction. Objective data may reveal shortness of breath, coughing, wheezing, and reduced breath sounds.

Heart Failure

• Rationale:Cough can be a symptom of heart failure, especially when it occurs at night or is accompanied by shortness of breath and swelling in the legs. Objective data may reveal jugular venous distension, edema, and abnormal heart sounds.

Gastroesophageal Reflux Disease (GERD)

• Rationale:GERD can cause coughing due to the reflux of stomach contents into the esophagus. Objective data may reveal heartburn, regurgitation, or a sour taste in the mouth.

Foreign Body Aspiration

• Rationale:Foreign body aspiration can cause coughing, especially if the object is lodged in the airway. Objective data may reveal difficulty breathing, wheezing, or cyanosis.
