The nurse caring for a patient with a disposable chest drainage system can promote effective tube function and patient safety by:
taping all connections within the system
turning on suction to 35 cm
keeping the system at the level of the patient's chest
looping the tubing between the mattress and the bed rail to minimize length
The Correct Answer is A
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.

Correct Answer is D
Explanation
A) Took five quick "huffs" and then coughed vigorously. Huff coughing is a technique used to clear secretions, but it is not the correct method for using an incentive spirometer.
B) Exhaled deeply and then inhaled quickly and forcefully three times. Rapid inhalation and exhalation do not promote effective lung expansion or alveolar recruitment.
C) Took five deep breaths slowly every 4 hours. This frequency is insufficient to prevent atelectasis and postoperative lung complications.
D) Took 10 slow, deep breaths every hour. Taking 10 slow, deep breaths every hour encourages full lung expansion and prevents complications such as atelectasis.
Correct Answer is D
Explanation
A. Increased secretion production: Older adults often experience decreased secretion clearance rather than increased production.
B. Thinning of the alveolar membrane: Alveolar membranes tend to thicken, reducing efficient gas exchange.
C. Increased efficiency of the immune system: Aging typically causes immune function to decline, increasing susceptibility to infections.
D. Decreased elasticity of the respiratory tissues: Loss of elasticity reduces lung compliance, leading to diminished respiratory efficiency.
