Final answer:
The recommended position for postural drainage of the right upper lobe - posterior lung segment in an adult is Right Side-Lying.
Step-by-step explanation:
The recommended position for postural drainage of the right upper lobe - posterior lung segment in an adult is Right Side-Lying.
Postural drainage is a technique used to help mobilize secretions in the lungs and improve breathing. In this position, the person lies on their right side with their upper body elevated at a 30 to 45-degree angle. This allows gravity to assist in draining secretions from the right upper lobe - posterior lung segment.
By lying on the right side, the drainage from this segment can flow more easily downwards towards the larger airways, facilitating removal of secretions and improving respiratory function.
