Question

a nurse is caring for a client who has a chest tube in place that is attached to a water seal drainage system. which of the following findings should the nurse recognize as an indication of subcutaneous emphysema? diminished lung sounds on the affected side a dry, crackling sound at the insertion site when palpated absence of drainage in the collection chamber hyperresonance when percussing the affected lung

Explanation:

Subcutaneous emphysema occurs when air leaks into the subcutaneous tissue. When palpating the area, a dry, crackling sound (crepitus) can be heard due to the presence of air in the tissues. Diminished lung sounds are more related to lung - related issues like atelectasis or pneumothorax. Absence of drainage in the collection chamber is related to blockage or lack of fluid/air production. Hyperresonance on percussion is associated with air - filled spaces like pneumothorax.

Answer:

B. A dry, crackling sound at the insertion site when palpated
