Final answer:
A key assessment parameter in a baseline assessment of a client's skin integrity is the overall risk of developing pressure ulcers.
Step-by-step explanation:
A key assessment parameter in a baseline assessment of a client's skin integrity is the overall risk of developing pressure ulcers. This parameter helps to identify clients who may be at greater risk for developing pressure ulcers and allows for appropriate preventive measures to be implemented. It takes into account factors such as mobility, nutrition, and sensory perception, which can contribute to the development of pressure ulcers.
The other options mentioned, such as family history of pressure ulcers, presence of existing pressure ulcers, and the potential areas of pressure ulcer development, are important considerations as well but may not directly represent a key assessment parameter in a baseline assessment of skin integrity.
