Chapter 5, Problem 4CCS
21-Year-Old Female with Skeletal Injuries
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.
4. NCLEX-STYLE Liliana's cyanosis is clinically significant because:
a. It indicates that she has less hemoglobin reaching her lips and fingers.
b. It indicates that her blood is low in oxygen.
c. It indicates that there are more melanocytes developing in her lips and fingers.
d. It indicates a buildup of bilirubin in her epidermis.

What protective mechanisms are impaired or deficient in the abraded areas?
This is a picture of Thick Skin - epidermis. Please use arrows to identify the following:
stratum corneum
stratum lucidum
stratum granulosum
stratum spinosum
stratum basale
Discuss the functional implications of the following structural changes in skin associated with aging.
1 less subcutaneous fat and decreased circulation in the dermis
2 decreased melanin production in the hair and skin
3 decreased cell proliferation in the hair follicle
4 reduced collagen and elastic production in the dermis
5 decreased activity of the eccrine sudoriferous glands

For this assignment, you are going to apply what you learned about these levels, specifically to the integumentary system. Below is a visual tool (you are not required to present your answer in that format) to guide you through this assignment. Your job will be as follows: Fill in all of the structures within the integumentary system that fit into each level or organization. For example, one of the structures that would fit into the "tissue level" might be areolar connective tissue. Describe how the components of each level fit together to create the next higher level in 2-3 sentences. For example, how does the buildup of the cellular level lead to the development of the tissue level? You will be compiling the components of the cellular, tissue, organ, and organ system levels, not the chemical or organism levels.arrow_forwardIdentify the epidermal layer(s) in which the following cancers arise: (a) basal cell carcinoma; (b) malignant melanoma; (c) squamous cell carcinoma.arrow_forward
