The nurse loosens mucus plugs by using percussion on a patient over the area of the:

sternum

thorax

midaxillary line on the rib cage

spine between the scapulae

Answer and Explanation

The Correct Answer is B

A) Sternum. Percussion over the sternum is ineffective and may cause discomfort.
B) Thorax. Percussion on the thorax helps loosen mucus in the underlying lung fields.
C) Midaxillary line on the rib cage. This area is not typically targeted for percussion.
D) Spine between the scapulae. Percussion on the spine is not advisable due to the potential for discomfort and ineffectiveness. The area between the scapulae is also less effective for loosening mucus compared to the thorax.

Correct Answer is B

Explanation

A) In the morning immediately after breakfast. Performing postural drainage after eating may induce nausea and vomiting.
B) Shortly after the patient arises in the morning, before breakfast. This timing allows mucus to drain more effectively since the patient has been lying down overnight, and an empty stomach minimizes the risk of vomiting.
C) 30 minutes after lunch. Postural drainage should be performed at least 1 to 2 hours after meals to prevent gastrointestinal discomfort.
D) 1 hour after supper. While this timing is better than immediately after eating, morning sessions are generally more effective.

A. taping all connections within the system B. turning on suction to 35 cm C. keeping the system at the level of the patient's chest D. looping the tubing between the mattress and the bed rail to minimize length

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.
