Clinical Assessment Techniques for Respiratory Health Quiz

Spirometry is a common technique measuring lung function by assessing the volume and flow of inhaled and exhaled air.

Pulse oximetry measures the percentage of hemoglobin saturated with oxygen, indicating oxygen levels in the blood.

The respiratory system's main function is gas exchange, delivering oxygen to tissues and expelling carbon dioxide produced by cellular metabolism.

Tidal volume is the amount of air exchanged in a normal breath cycle, excluding additional forced or reserved breaths.

Taste testing is not relevant to respiratory assessment; it assesses gustatory function rather than respiratory health.

FEV1 measures the amount of air forcefully exhaled in the first second of a spirometry test, indicating lung function.

CT scan provides detailed cross-sectional images of the lungs, aiding in the diagnosis of respiratory conditions.

Polyuria, excessive urination, is not a typical respiratory distress symptom; it indicates issues with the urinary system.

Bronchitis involves airway inflammation, leading to coughing and difficulty breathing.

Barrel chest is a characteristic feature of COPD, indicating chronic air trapping and lung hyperinflation.

Pursed-lip breathing helps prolong exhalation, preventing airway collapse and reducing resistance during breathing.

Bradypnea, slow breathing, can occur in respiratory acidosis due to the retention of carbon dioxide.

Hypocapnia, low carbon dioxide levels, is not typically associated with COPD, which often involves carbon dioxide retention.

Airway resistance measures the force opposing airflow within the respiratory system, often elevated in conditions like asthma.
