Cough Reflex Test Practice 2025 – Complete Exam Prep

Retractions in a patient typically suggest reduced lung volume. This physical sign occurs when there is increased effort to breathe due to a partial collapse of the airway or restrictions in the lung tissue, which can happen in conditions like pneumonia, asthma, or other forms of airway obstruction. When lung volume is reduced, the body compensates by using accessory muscles to help draw air into the lungs, leading to the visible pulling in of the skin around the ribcage and sternum during inhalation. This indicates that the patient is experiencing difficulty breathing, as the lungs are not expanding efficiently.

The other options do not accurately describe what retractions indicate. Increased lung compliance refers to situations where the lungs expand easily, which would not typically lead to retractions. Normal breathing patterns do not involve retractions; instead, they usually present with relaxed and even respiratory movements. Enhanced respiratory effort could be a contributing factor to the presence of retractions, but it does not encapsulate the fundamental meaning behind the physical sign itself, which primarily correlates with reduced lung volume.
