A look at skin disorders

As the body’s main protective system, the skin’s various functions include sensory perception, regulation of temperature, prevention of water and electrolyte loss, and excretion. Nursing care for skin disorders requires careful examination and observation, prevention of infection, and hands-on treatment regimens, such as topical application of medication and wound debridement.

Anatomy and physiology:

The skin (integument) covers the body’s internal structures and protects them from the external world. The skin has two distinct layers:

  • The epidermis, or outer layer, is made up of squamous epithelial tissue, which itself contains several layers—the stratum corneum, stratum lucidum, stratum spinosum, and stratum basale.

• The dermis, the deeper second layer, consists of connective tissue and an extracellular material called matrix, which contributes to the skin’s strength and pliability. The dermis contains and supports the blood vessels, lymphatic vessels, nerves, and sweat and sebaceous glands and serves as the site of wound healing and infection control. Beneath the dermis lies the subcutaneous tissue.
