What causes skin tears?

1. Chemical irritation from products

2. Excessive moisture exposure

3. Superficial skin layers sliding against each other

4. Contact with sharp objects

The correct answer is: Superficial skin layers sliding against each other

Skin tears occur primarily due to the sliding of superficial skin layers against each other, which can happen from friction or trauma. This mechanism often affects the delicate skin of older adults or those with compromised skin integrity, leading to a separation of the epidermis from the dermis. This is particularly relevant in patient care where mobility and activity are factors; for instance, when an elderly person’s skin is dragged across a rough surface or when they experience a sudden movement that causes their skin to stretch unnecessarily. Understanding this primary cause allows healthcare providers to implement preventive measures, such as careful handling and the use of protective garments, to minimize the risk of skin tears in vulnerable populations.
