A nurse is performing pulmonary hygiene for a client who has pneumonia and positions the client on his left side in Trendelenburg position. From which of the following lung segments should the nurse expect secretions to be mobilized with the client in this position?
Lateral segment of the right lower lobe
Lateral segment of the left lower lobe
Posterior segment of the right middle lobe
Posterior segment of the right lower lobe
The Correct Answer is A
A. Lateral segment of the right lower lobe is the correct answer because placing the client on the left side in Trendelenburg position promotes drainage from the right lower lobe’s lateral segment by using gravity to mobilize secretions.
B. Lateral segment of the left lower lobe would require the client to be positioned on the right side rather than the left.
C. Posterior segment of the right middle lobe would require the client to be positioned in a different way, typically supine with a slight Trendelenburg tilt.
D. Posterior segment of the right lower lobe would require a prone position in Trendelenburg, not left-side lying.
