VENTRICULAR SEPTAL DEFECT

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A patient, age 41, undergoes a right upper lobectomy. Postoperatively, he has a chest tube connected to an underwater seal with suction. One day after surgery, the nurse detects no bubbling in the suction compartment. What would be the best nursing action at this time?
A
Milk the chest tube using slow even strokes
B
Add more sterile water to the suction department
C
Check the practitioner’s order for amount of suction, and increase pressure until gentle bubbling occurs
D
Check the practitioner’s order for amount of suction and increase the water seal by 10 cm.
Explanation: 

Detailed explanation-1: -The water seal chamber should be assessed every hour for any potential air leaks. An air leak will be characterised by intermittent bubbling in the water seal chamber when the patient with a pneumothorax exhales or coughs. Continuous bubbling of this chamber indicates large air leak between the drain and the patient.

Detailed explanation-2: -Assessment of lung sounds is vital to nursing care of a client with a chest tube. Monitoring the client’s vital signs (blood pressure and pulse) every fifteen minutes, their level of consciousness, and their ability to breathe on their own.

Detailed explanation-3: -Full expansion of remaining lung tissue is the most important issue following a pulmonary lobectomy, for which chest tubes are used for proper drainage of both air and fluid, with the outflow considered to reflect the condition of the thoracic cavity after surgery (1, 2).

Detailed explanation-4: -If bubbling disappears when you clamp the tubing, suspect an air leak at the insertion site or from within the chest wall. Assess the insertion site; if you detect a leak, apply petroleum gauze and a sterile occlusive dressing to seal it off.
