Integumentary Flashcards
(231 cards)
Describe the homeostasis phase of healing.
- vasoconstriction to reduce loss and prevention of infection
- fibrin plug is formed
- 10-15 minutes after injury
- occurs after growth factors are released
Describe the inflammation phase of healing.
- 24-48 hours
- cardinal signs of inflammation become apparent due to vasodilation of non-injured vessels to allow leukocytes and growth factors in the area of injury
- phagocytosis and revascularization
What are the 4 key cells in the inflammation phase?
- platelets
- leukocytes
- macrophages
- mast cells
What phase of the healing process can DM impair?
Inflammation phase
When does inflammation phase occur?
24-48 hours after injury
When does homeostasis phase occur?
10-15 minutes after injury
What are the 4 primary events that occur during the granulation/proliferation/fibroblastic phase?
- angiogenesis
- granulation formation
- wound contraction
- epithelialization
What are the 3 primary cells associated with the granulation phase? What do they provide?
- myofibroblasts (wound contraction)
- fibroblasts (collagen, elastin, and glycosaminoglycan production)
- epithelial cells (epithelialization)
When does the maturation/matrix formation stage occur?
2-4 weeks after injury
can last up to years- collagen synthesis and alignment)
When is a wound pink during maturation phase?
Weeks 6-12
When is a wound lavender/soft pink during maturation phase?
months 12-15
What medications can delay wound healing?
- corticosteroids
- chemotherapy
- NSAIDS
diagnosis
excessive dryness of the skin with shedding of the epithelium
xeroderma
What can xeroderma indicate?
- deficiency in thyroid function
- DM
What is clubbing?
thickened and rounded nail end with spongy proximal fold
(true/false) clubbing develops over time
false (at birth)
What is clubbing indicative of?
- crohn’s disease
- cardiac-related cyanosis
- lung cancer/hypoxia
- ulcerative colitis
- biliary cirrhosis
- neoplasm
- GI involvement
What is schamroth’s window test used for?
clubbing
Loss of diamond shape when nails from each hand are placed back-to-back
Changes in nails often indicate what?
Systemic issues unless congenital
Palmar erythema could indicate what?
liver or renal issues
What can pallor indicate?
- anemia
- internal hemorrhage
- lack of sunlight exposure
What skin change is seen with the following:
- arterial insufficiency
- syncope
- chills
- shock
- vasomotor instability
- nervousness
pallor
definition
brownish yellow spots that may be due to aging, uterine and liver malignancies, or pregnancy
liver spots
Brown skin is often associated with what?
Venous insufficiency
