A nurse is assessing the chest drainage system of a client who is 24 hr post-thoracotomy. The nurse notes slow, steady bubbling in the suction control chamber. Which of the following actions should the nurse take?

Choice A reason: Slow, steady bubbling in the suction control chamber is normal, indicating proper suction function, not an air leak. Checking for leaks is unnecessary unless bubbling is vigorous or in the water seal chamber, making this choice incorrect for the observed finding. Choice B reason: Notifying the provider is unwarranted, as slow, steady bubbling in the suction control chamber is an expected finding post-thoracotomy. It reflects normal system function, not a complication, making this choice unnecessary compared to continued monitoring. Choice C reason: Slow, steady bubbling in the suction control chamber indicates the chest drainage system is functioning correctly, maintaining negative pressure. Continuing to monitor ensures ongoing assessment without intervention, aligning with standard care post-thoracotomy, making this the correct action. Choice D reason: Increasing suction pressure is inappropriate, as slow, steady bubbling suggests adequate suction. Excessive pressure risks lung damage or system malfunction, making this choice incorrect and potentially harmful for the client’s chest drainage system.
