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. Palpating the insertion site of a chest - tube and feeling a dry, crackling sound (crepitus) is indicative of air in the subcutaneous tissue. Diminished lung sounds may indicate atelectasis or other pulmonary issues. Absence of drainage in the collection chamber is related to the function of the drainage system or lack of fluid/air to drain. Hyperresonance on percussion is associated with hyperinflated lungs like in emphysema (not subcutaneous emphysema).

Answer:

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