Integumentary System
A terrible collision between a trailer truck and a bus has occurred on Route 91. Several of the passengers are rushed to area hospitals for treatment. We will follow a few of these people in clinical case studies that will continue through the book from one organ system to the next.
Examination of Mrs. DeStephano, a 45-year-old woman, reveals several impairments of homeostasis. Relative to her integumentary system, the following comments are noted on her chart:
Epidermal abrasions of the right arm and shoulder
Severe lacerations of the right cheek and temple
Cyanosis apparent
The lacerated areas are cleaned, sutured (stitched), and bandaged by the emergency room (ER) personnel, and Mrs. DeStephano is admitted for further tests.
Relative to her signs:
What protective mechanisms are impaired or deficient in the abraded areas?

- A 74-year-old woman is transported to a regional burn center after being rescued from a house fire. Apparently, a space heater was knocked over and an area rug caught fire. The fire quickly spread throughout the house. She did not have any functional smoke detectors and became trapped in a back bedroom. Using the "rule of nines," the burn team estimates that approximately 30% of her TBSA is burned. Most of the burns are thought to involve the entire dermis, and the area looks waxy and white. This type of wound is considered to be: 1. Deep partial-thickness 2. Third-degree 3. Superficial partial-thickness 4. Full-thicknessarrow_forwardtrue or false ____18.
