Which body system includes skin and its appendages such as hair, nails, and glands?

• A. Integumentary System
• B. Infection Prevention
• C. Immobility
• D. Intake

Answer: (A)

Skin, hair, nails, and glands all belong to one body system that forms the body's outer covering. This integumentary system protects internal tissues from injury and infection, helps regulate body temperature through sweat and blood flow, and provides sensation via nerve endings. Hair offers warmth and protection, nails protect the fingertips and assist with grasping, and glands produce sweat and oils to maintain moisture and protection. So when the question mentions the skin or its related structures, it points to the integumentary system. Other options describe care domains or conditions rather than a body system: infection prevention, immobility, and intake refer to safety practices, mobility status, and nutrition/fluids.
