Asymmetry
Border irregularity
Color
Diameter at least 1/4 in.
Evolution
What is an actinic keratoses?
Premalignant lesions
More common in men
What is a squamous cell carcinoma (SCC)?
Cancer of epidermis
Metastasis common
Can be related to chronic skin damage
Most common in people with darker skin
Looks scaly, slightly red
What is a basal cell carcinoma (BCC)?
Basal cell layer of epidermis
Metastasis rare
Genetic, chronic irritation
Starts as small fleshy bumps
Looks shiny, red, elevated
What’s a melanoma?
Pigmented cancer arising in melanin producing epidermal cells
Highly metastatic
Genetic, excessive UV exposure
What are the 4 types of skin cancer?
Actinic keratoses
Squamous cell carcinoma
Basal cell carcinoma
Melanoma
How is skin cancer/lesion treated?
Electrodesiccation and curettage (dig out)
Surgical excision (margins of 5 cm are best)
Mohs (for high risk or large BCC)
Cryosurgery (freezing area)
What kind of diagnostic study is done for scabies?
Scraping
How is contact dermatitis managed?
Obtain hx to identify causative agent
Avoidance therapy (once cause identified)
Steroid to suppress inflammation
Cool/moist dressings over topical steroids and increase absorption
No occlusive dressing with steroid
What is psoriasis?
A scaling disorder related to dermal inflammation
Abnormal growth of epidermal cells in the outer skin layers
Autoimmune rx, lifelong with exacerbation & remissions
What are the physical cues of scabies?
Shows up in folds, warm, moist areas
Pruritic
Blisters (small, red)
Can mimic contact dermatitis
Why is herpes zoster (singles) in eye a medical emergency?

Irregular erythema
Induration
Boggy or firm
What are the characteristics of stage 2 pressure ulcer?
Damage that includes epidermis, dermis, or both
Shallow ulcer, blister or abrasion
What are the characteristics of stage 3 pressure ulcer?
Injury to SubQ tissue
Goes to the underlying fascia, but not through
May have undermining
Deeper crater
What are the characteristics of stage 4 pressure ulcer?
Injury to the tissue that goes through the fascia
Includes structural visibility involvement: muscle, bone, tendon/ligament
May have osteomyelitis or septic arthritis
When is a pressure ulcer unstageable?
When unable to determine the depth of tissue damage due to necrotic tissue covering wound bed
How can you prevent pressure ulcers?
Frequent repositioning, avoid over sedation
Barrier cream if incontinent
Pressure reduction with mattresses/cushion
Assessment
Adequate nutrition & hydration (30-35kcal/kg, 1-1.5g/kg protein, 1mL/kcal fluid)
The Norton scale is used to
Identify risk of pressure ulcer
Less the number, higher the risk
Scale of 5 to 20
How is pressure ulcer treated?
Pain control
Keep what is wet wet and what is dry dry
What prophylactic treatment should be given to a patient who is on continuous opioid analgesic?
Treat constipation
Why can pain assessment in older adults be difficult?
Due to multiple chronic conditions
High incidence of cognitive impairment
How can you assess pain in cognitive impaired patients?
Baseline information (VS, agitation, ability to walk, stand, move, eating pattern, appetite, sleep pattern, elimination habits, etc.)
