Is it true or false that dehydration is the leading cause of pressure ulcers?

The statement that dehydration is the leading cause of pressure ulcers is false. While dehydration can contribute to skin integrity issues and exacerbate existing conditions, the primary factors leading to pressure ulcers are prolonged pressure on the skin, particularly due to immobility. When blood flow to an area is restricted for an extended period, the skin and underlying tissues can become damaged, leading to the formation of pressure ulcers.

Other significant risk factors include moisture (which can come from sweat or incontinence), friction, and shear forces, along with nutritional status and underlying medical conditions. Dehydration can play a role in skin health, but it is not the most critical factor in the formation of pressure ulcers. Therefore, understanding the primary causes emphasizes the importance of mobility, regular repositioning, and comprehensive skin care in preventing these injuries.
