Which of the following is an expected outcome of chest tube insertion?

A) Mild chest pain is maintained.
B) Breath sounds are auscultated in all lobes.
C) Drainage from the pleural cavity increases over time.
D) Lung expansion is increased beyond the unaffected side.

When breath sounds are auscultated in all lobes,lung expansion is symmetrical,oxygen saturation (SaO?)is stable or improved,and respirations are nonlabored.Chest pain is not an expected outcome.Treatment is effective when the patient reports no chest pain.Drainage from the pleural cavity decreases over time with reexpansion of the lung.Lung expansion would be equal to preinjury status.
