Textbook Question
Chapter 5, Problem 1CCS
21-Year-Old Female with Deep Lacerations
While riding her bike to campus, 21-year-old Liliana Rose was struck by a car. Examination in the Emergency Department reveals several injuries. Relative to her integumentary system, the following comments are noted on her chart:
•Epidermal abrasions of the right lateral upper arm and anterior shoulder.
•A deep, 2-cm laceration extending vertically on right lateral cheek and a horizontal 1–cm laceration on the temple.
•Cyanosis is apparent in her nail beds and lips.
The lacerated areas are cleaned, sutured (stitched), and bandaged by the emergency room (ER) personnel.
1. NCLEX-STYLE Liliana's epidermal layer has been damaged. Which statement best explains the significance of this damage?
a. It’s not significant, because the cells in the epidermis are already dead.
b. It’s significant because cells in the epidermis give rise to all the cells in all the different skin layers.
c. It’s significant because disrupting the epidermis will cause severe, sometimes life-threatening bleeding.
d. It’s significant because the cells of the epidermis protect against evaporative water loss, UV radiation, and infection.
