A nurse is caring for a client who has left lower-lobe atelectasis. In which of the following positions should the nurse place the client for postural drainage?
A.
Supine in low-Fowler’s position
B.
Side-lying with the right side of the chest elevated
C.
Right lateral in Trendelenburg position
D.
Prone with pillows under the lower extremities
The Correct Answer and Explanation is :
The correct answer is C. Right lateral in Trendelenburg position.
Explanation:
Atelectasis is the collapse or incomplete expansion of the alveoli within the lungs, which reduces the ability of the affected area to participate in gas exchange. In this case, the client has left lower-lobe atelectasis, meaning the left lower lobe of the lung has partially or completely collapsed. Postural drainage is a technique used to help clear secretions from the lungs by positioning the client in such a way that gravity aids in the drainage of mucus or fluid from the affected lung segments.
Understanding Postural Drainage:
Postural drainage involves placing the client in specific positions that allow gravity to assist in mobilizing secretions from the lungs’ periphery to larger airways where they can be more easily expectorated or suctioned out. The position chosen depends on the location of the atelectasis or secretions.
- Right lateral in Trendelenburg position: In the case of left lower-lobe atelectasis, the Trendelenburg position, where the body is tilted so that the head is lower than the feet, is effective. The client should be placed on their right side, allowing gravity to facilitate the drainage from the left lower lobe of the lung. The Trendelenburg position enhances the effect of gravity in helping secretions move from the lower portions of the lungs upward, where they can be expelled more easily.
- Other Options:
- A. Supine in low-Fowler’s position: This position is not effective for drainage of the lower lobes of the lungs because it does not use gravity to mobilize secretions effectively.
- B. Side-lying with the right side of the chest elevated: This position might help drain the right lung but would not be beneficial for the left lower lobe.
- D. Prone with pillows under the lower extremities: This position is also not conducive to effective postural drainage of the left lower lobe.
In conclusion, placing the client in the right lateral Trendelenburg position is optimal for postural drainage of left lower-lobe atelectasis, as gravity assists in the mobilization and clearance of secretions from the affected lung area.
