The integumentary system serves as the body’s first line of defense and plays a vital role in protection, thermoregulation, sensory perception, and homeostasis. Disorders of this system, including infections, burns, neoplasms, and inflammatory conditions, often present complex clinical challenges requiring accurate assessment, critical thinking, and evidence-based nursing interventions. By mastering the principles presented in this book, readers are expected to develop a stronger foundation in understanding pathophysiology, clinical manifestations, diagnostic evaluation, and nursing care strategies that are holistic, patient-centered, and scientifically grounded.
