A nurse is planning care for a client who has a chest tube. Which of the following interventions should the nurse include in the plan? (Select all that apply.)

Marking the drainage output on the collection chamber allows monitoring for increased, decreased, or changed drainage. Stripping the chest tube can cause excessive negative pressure. The water seal chamber should not have water added; if it evaporates, it indicates a problem. Clamping the chest tube is done only per provider order for specific reasons. The collection chamber must be kept below the level of the client's chest to allow gravity drainage.
