Which condition is characterized by thin and fragile skin that is more susceptible to breakdown?

1. Pressure ulcers

2. Macerated skin

3. Keratosis

4. Eczema

The correct answer is: Macerated skin

Macerated skin is characterized by an overhydration condition that leads to skin breakdown and fragility. This occurs when the skin is exposed to moisture for prolonged periods, which can make it soft and weak. Individuals with macerated skin are generally more prone to skin tears and breakdown due to the excessive moisture compromised the skin's barrier function. In contrast, pressure ulcers arise from prolonged pressure on the skin, typically over bony prominences, leading to localized areas of tissue necrosis. Keratosis is a term that encompasses various skin conditions resulting in thicker, often rough patches of skin, which is not consistent with fragility. Eczema, while it can lead to skin irritation and inflammation, does not specifically imply the same level of fragility as seen in macerated skin. Thus, the defining characteristic of macerated skin—its thinness and susceptibility to breakdown—aligns directly with the question prompt, making it the correct answer.
