The nurse is planning care for a client with a chest tube attached to a Pleur-Evac drainage system. The nurse should include which interventions in the plan? Select all that apply.

Changing the client's position frequently is necessary to promote drainage and ventilation. Maintaining the system below waist level is indicated to prevent fluid from reentering the pleural space. Adding water to the suction control chamber is an appropriate nursing action and is done as needed to maintain the full suction level prescribed. Taping the connection between the chest tube and system is also indicated to prevent accidental disconnection. To prevent a tension pneumothorax, the nurse avoids clamping the chest tube, unless specifically prescribed. In many facilities, clamping of the chest tube is contraindicated by agency policy.
