Answer to Question 1

A
Continuous bubbling in the water-seal chamber with an absence of bubbles in the suction control chamber indicates that there is a leak in the system. Normal functioning is indicated by gentle, continuous bubbling in the suction chamber and occasional bubbling in the water seal, with fluctuations on inspiration and expiration. Constant bubbling in the water seal or a sudden, unexpected stoppage of water-seal activity is considered abnormal and requires immediate attention. Insufficient suction pressure has little to no bubbling in the suction chamber.

Answer to Question 2

B
When blood appears on the dressing, verify that the system is intact, and change the dressing. The IV should be discontinued in the event of infiltration or phlebitis. If bleeding occurs around the venipuncture site and the catheter is within the vein, gauze dressing may be applied over the site. Be aware that if gauze dressing is used, it must be removed to accurately assess the insertion site. Elevation is used in cases of infiltration to reduce edema. Warm compresses are used in cases of phlebitis.
