NUR 502 Advanced Pathophysiology Study Guide: Review Topics
for Chapter 13 & 14 |Latest Update with Complete Solution-STU
Chapters 13 & 14 (Integumentary & Sensory Functions)
Chapter 13 - Integumentary Function
1- Changes in the skin that indicate a pressure ulcer
o Stage 1: intact skin with nonblanchable erythema
o Stage 2: partial thickness loss of skin with exposed dermis
o Stage 3: Full thickness skin loss, adipose is visible in the ulcer
o Stage 4: full thickness skin and tissue loss with exposed or directly palpable fascia,
muscle, tendon, ligament, cartilage or bone in the ulcer
o Unstageable: full thickness skin and tissue loss, extent of tissue damage cannot be
confirmed because of slough or eschar
2- Skin lesions for each different type of psoriasis
o Plaque: Thick, red plaques, covered by flaky, silver-white scales (bleed); usually located
on the scalp, elbows, knees, gluteal cleft
o Erythrodermic: intense erythema that covers a large area from head to toe (pruritic and
painful)
o Guttate: small, pink-red papules (droplike); found in trunk and extremities
o Inverse: erythema and irritation usually with no scaling; armpits, groin, skin folds
o Pustular: Papules or plaques with pustules surrounded by erythema; may cause systemic
complications
3- Review the lesion types/description, and most common locations in conditions: Lichen planus,
Pityriasis rosea, Psoriasis, Acne rosacea.
4- Skin lesions of most concern (shapes, borders, color, description, consistency, etc.):
Asymmetry, borders that are irregular, color that varies, diameter that is usually larger than 6mm,
sensory changes, skin growth that bleeds and will not heal, skin growth that changes in
appearance over time
5- Review Herpes zoster and how to explain a patient its pathophysiology
6- Tinea corporis (ringworm) Type of infection? Fungal infection
7- Review lesion descriptions for Impetigo, Rubella, Tinea capitis, Atopic dermatitis and how to
recognize each of them in a presented case.
8 -Describe Skin lesions caused by tinea corporis: Lesions are round patches that have a red
border with central clearing and pruritic, no drainage
9- What is the cause of molluscum contagiosum? A poxvirus
, 10- Review possible complications after being exposed to a fire.
