Part 1 starting from burns

Question 1

Distinguish between the 3 classes of burns.

Answer 1

1) Superficial burns(1st degree) : Confined to epidermis Produces erythema and discomfort Heals in 3-5 days

2)Superficial partial thickness (2nd degree)-Upper level of dermis Characterized by blisters, red, weepy, thin eschar, severe pain
Deep partial thickness- Lower dermis Absence of blisters, sometimes moderate thickness eschar, white, less weepy Superficial nerve endings damaged

3) Full thickness (3rd degree)- Epidermis and dermis destroyed – White, yellow, brown – No pain – Thick, inelastic eschar – Grafting necessary

Question 7

Herpes zoaster signs and symptoms

Creates painful sores resembling those of chickenpox

Question 8

Contrast a hypertrophic scar to a keloid.-

Answer 8

Keloid- The tissue extends beyond the borders of the original wound More haphazard organization of collagen fibers Tends to recur after excision

Hypertrophic- Remain within boundaries of wound Collagen synthesis > normal skin Collagen aligned in whorls Decreased tensile strength

Question 9
