Correct Answer is A
Explanation
A) Taping all connections within the system. Taping all connections helps prevent air leaks, which can compromise the function of the chest drainage system.
B) Turning on suction to 35 cm. Suction levels are typically set between 10 to 20 cm of water pressure. 35 cm is excessive and may cause lung tissue damage.
C) Keeping the system at the level of the patient's chest. The drainage system should always be kept below the level of the chest to promote gravity drainage and prevent backflow.
D) Looping the tubing between the mattress and the bed rail to minimize length. Tubing should not be looped or kinked, as this can obstruct drainage and compromise system function.
