Study These Flashcards
A

Fisted

Extended of slight flexion

25
How long does a scar take to mature?
At least 12 months
26
List the characteristics of immature/active scars, and mature scars
Immature Scars: - Red - Raised - Ridged Mature Scars: - Pale - Planar - Pliable
27
T or F? Hypertrophic scars stays between the wound borders, keloids expand beyond the wound borders
True
28
Patients with thermal burns should receive immediate care if...
- full thickness burn - partial thickness >/= 10% TBSA - partial or full thickness burns on the face - patient has burn and other comorbidities
29
List the healing times for different burns
Superficial: <7 days Superficial partial thickness: 7-21 days Deep partial thickness: 21-35 days Full thickness: >30 days Full thickness (to bone, muscle, subcutaneous): N/A
30
What is an abrasion?
- Wound caused by friction to the skin's surface - May be superficial or partial thickness Ex: skinned knee, road rash, floor burn, raspberry
31
What do abrasions look like?
- May or may not be contaminated - Mild, stinging sensation - Light to mod bleeding - Rarely progress to be chronic wounds - Risk for infection if patient is older or immunocompromised
32
Which interventions should be used with abrasions?
- Irrigate with water or saline - Selective or non-selective debridement - Clean wounds should be covered with a moisture-retentive dressing - Contaminated wounds should use antimicrobial and gauze - Patient can shower but not bathe/swim until skin barrier is restored Potential dressings: Film + Gauze
33
What is a laceration?
- Caused by cutting or tearing of the skin surface - Ranges from partial thickness to deep structures - Smooth or irregular - Varying degrees of contamination - May bleed profusely
34
Which interventions should be used with lacerations?
- Clean, minor wounds do not require tetanus prophylaxis (puncture wounds sometimes do) - Monitor for infection and dehiscence - May shower but not bathe or swim without an occlusive dressing - Excessive bleeding would be referred to emergency care facility
35
What is a skin tear?
- Traumatic wound resulting from shear or friction forces that separate the epidermis and dermis - Partial thickness - Extremely common and typically avoidable - Most common on arms, hands, pretibial region - Most common with elderly individuals
36
What does a skin tear look like?
- Linear tear or flap - Wound edges can be approximated and may have tissue defect - Slight serous drainage - Minimal bleeding - Minimal pain
37
Which interventions should be used with skin tears?
- Irrigate with saline or water - Treat with skin sealant - Moisture retentive dressing (hydrogel, gauze) - Avoid adhesives - Typically heal without complication - Watch for infection (especially in the elderly)
38
Describe surgical wounds
- Keep clean and dry for 24-48 hours - Minimal draining/bleeding Precautions: - Sutures are more likely to cause inflammation than staples - May have delayed sensitivity or allergic reaction to chemical agents
39
Describe a dehisced surgical wound
- Typically occurs 4-14 days after surgery - Present with .5-3.4% of abdominopelvic surgeries - High mortality rate - Contraindications include estim, pulse lavage, US Patient factors include: malnutrition, diabetes, anemia, COPD, steroids, smoking
40
T or F? Dehisced surgical wounds result from too much tension on the wound edges
True
41
Describe radiation-induced skin damage
- Those receiving both radiation and chemo are at greater risk for skin reactions - 95% of individuals who receive radiation get some type of skin damage - Inhibits inflammatory response and proliferative phase of healing Patient factors: Age, comorbidities, meds, nutrition, hydration, immune function
42
What do radiation-induced skin reactions look like?
- Ranges from dermatitis to full thickness tissue loss - Begins as early as 2-3 weeks of treatment start date (can last up to 4 weeks after finishing) - Mild reactions include inflammation, slight erythema, local edema - Dry, scaly, itchy, hyperpigmented skin due to sebaceous glands - Late tissue injury causes radiation fibrosis - Ulcers may occur up to an average of 9 years later
43
Describe the grading scale of radiation-induced skin reactions
Grade 1: - Faint erythema - Decreased sweating response - Epilation - Dry desquamation Grade 2: - Bright erythema - Tender to touch - Mod edema - Moist desquamation Grade 3: - Moist desquamation with pitting edema Grade 4: - Ulceration or necrosis
44
Which interventions should be used with radiation-induced skin reactions?
- Protect from mechanical forces (shear, friction, pressure) - Avoid perfumes - Should wear loose fitting clothing - Washing the area w water and maybe mild soap - Moisturize the intact skin - Desquamation benefits from silver dressing
45
List the do's and dont's for patients with irritated skin
Do - Perform daily skin checks - Bathe daily or less often using a mild soap - Protect the skin - Drink plenty of non-caffeinated, non-alcoholic fluids - Apply sunscreen to areas with radiation fibrosis Don't - Wear constrictive clothing - Scratch skin even if itchy - Use a hot tub - Use adhesive bandages - Massage during active treatment
46
What is pyoderma gangrenosum?
- Noninfectious, progressive necrotizing skin condition - 75% of patients have a systemic inflammatory condition Presentation: - Begins as a small, painful papule, vesicle or pustule on LE or trunk - Generally a cluster of ulcerations that rapidly expand - Progresses to full thickness ulcerations with irregular, purple borders - Undermining and lack of dermal support lead to epidermal necrosis - Differential diagnosis includes cancer, vasculitis, primary infection, drug induced skin reaction, spider bite, chronic VI Takes 1-3 years to heal
47
Which interventions are used for pyoderma gangrenosum?
- Medications - Corticosteroids - Local wound care
48
T or F? Pyoderma gangrenosum is slow wound healing (69% of wounds resolve after 1 year)
True
49
T or F? Pyoderma gangreneosum recurrence is common
True
50
What type of wound is caused by friction to the skin's surface?
Abrasion
51
Patients with abrasions or lacerations are advised to not do what
Take baths or go swimming without an occlusive dressing
52
Which population is most vulnerable to skin tears?
Infants and the elderly
53
Which modalities are contraindicated for dehisced (broken) surgical wounds
- EStim - US - Pulse lavage (w/ suction)
