A nurse in the ICU is caring for a client who has heart failure and is receiving a dobutamine drip. The nurse should identify that which of the following findings indicates that the medication is effective?

Choice A Reason: This choice is correct because slow, steady bubbling in the suction control chamber indicates that the suction is working properly and maintaining a negative pressure in the pleural space. The nurse should continue to monitor the client's respiratory status, such as breath sounds, oxygen saturation, and respiratory rate, to assess the effectiveness of the chest drainage system.

Choice B Reason: This choice is incorrect because checking the suction control outlet on the wall is not necessary unless there is no bubbling in the suction control chamber, which would indicate a problem with the suction source or setting. The nurse should ensure that the suction control outlet is set at the prescribed level, usually between 10 and 20 cm H2O.

Choice C Reason: This choice is incorrect because clamping the chest tube is not indicated unless there is a leak in the system or the chest drainage unit needs to be changed. Clamping the chest tube may cause a buildup of air or fluid in the pleural space, which can lead to tension pneumothorax or pleural effusion.

Choice D Reason: This choice is incorrect because checking the tubing connections for leaks is not necessary unless there is continuous bubbling in the water seal chamber, which would indicate an air leak in the system. The nurse should ensure that all tubing connections are tight and secure, and tape any loose connections.

Choice A Reason: This is incorrect because clamping the client's chest tube can cause a tension pneumothorax, which is a life-threatening condition that requires immediate intervention.

Choice B Reason: This is incorrect because increasing the client's wall suction can cause excessive negative pressure in the pleural space, which can damage the lung tissue and impair ventilation.

Choice C Reason: This is correct because repositioning the client can help relieve chest burning, which may be caused by irritation of the intercostal nerves by the chest tube or by air trapping in the pleural space.

Choice D Reason: This is incorrect because stripping the client's chest tube can create high negative pressure in the pleural space, which can damage the lung tissue and impair ventilation.
