Correct Answer is B

Explanation

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.

A. Loop the tubing of the chest tube on the client's bed. B. Place the chest tube drainage system above the level of the client's heart. C. Strip the client's chest tube every 2 hrs. D. Tape the connections on the client's chest tube.

Correct Answer is D

Explanation

A. Loop the tubing of the chest tube on the client's bed: Looping can create kinks or blockages, impeding drainage and increasing the risk of complications.
B. Place the chest tube drainage system above the level of the client's heart: This would prevent gravity drainage, leading to fluid accumulation in the pleural space.
C. Strip the client's chest tube every 2 hrs: Stripping can create high negative pressure, damaging lung tissue.
D. Tape the connections on the client's chest tube: Securing all connections with tape helps maintain a closed system and prevents air leaks.
