Final answer:
Turning the client every 2 to 4 hours is the best nursing intervention to keep the skin intact of a bedridden client.
Step-by-step explanation:
To keep the skin intact of a bedridden client, the best nursing intervention is to turn the client every 2 to 4 hours. This helps to relieve pressure on specific body parts and promotes circulation, reducing the risk of developing bedsores or decubitis ulcers. Using a lift sheet to move the client in bed can also be helpful in preventing excessive pressure on the skin.
