Q

Wound healing

A

Primary intention: wound is closed or approximated using sutures, staples, or glue
Secondary intention: wound is left open to heal through granulation, contraction, and epithelialization
Tertiary intention: intentionally leave wound open to debride necrotic tissue or wait for inflammation to subside, then close it at a later time

Atopic dermatitis (Eczema)
46
Eczema treatment
Moisturizes, identifying and avoiding triggers, topical steroids, antihistamines
47
Eczema patient education
Shower in LUKE-WARM water, apply emollient right after shower to trap moisture in skin, avoid scratching skin (increases risk for skin damage and infection)
48
Development of waxy, flaky plaques and scales on areas of body that have a large number of sebaceous glands (scalp, etc.)

53
UV light therapy for severe psoriasis
- provide eye protection for patient - psoralen med may be given to increase skin sensitivity to UV light which enhances effects of therapy - NOTE: this therapy increases risk for skin cancer
54
Emergent phase of burns
- begins at time of injury and lasts 24-48 hours - focus: maintain airway, provide fluid resuscitation, preserving organ function
55
Acute phase of burns
- begins once fluid resuscitation is complete and ends with wound closure - Focus: infection control, wound healing, nutrition, mobility
56
Rehabilitative phase of burns
- begins when there is wound closure until patient achieves maximal function - focus: psychosocial adjustment and prevention of contractures; reconstructive procedures
57
Emergent phase nursing interventions
Stop burning process, maintain airway, administer oxygen as ordered, assess for signs of inhalation injury (singed eyebrows or nasal hair, sooty sputum), provide IV fluid resuscitation using large bore catheter to prevent hypovolemia, IV opioid analgesics, keep patient warm and NPO, insert NG tube and catheter, administer tetanus vaccine
58
Rule of nines for burn assessment
- entire head: 9% (4.5% anterior and posterior) - entire trunk: 36% (18% anterior and posterior) - each upper extremity: 9% (4.5% anterior and posterior) - each lower extremity: 18% (9% anterior and posterior) - perineum: 1%
59
Superficial of first degree burn
- limited to epidermis - skin pink or red in color - mild edema, but NO blisters - ex: sunburn
60
Superficial partial-thickness or second-degree burn
- damage to upper layer of dermis - red or pink color, mild to moderate edema, presence of blisters
61
Deep partial-thickness burn (still second-degree)
- damage extends deep into dermis - red or white color, moderate edema, soft dry eschar
62
Full-thickness or third degree burn
- damage extends into subcutaneous tissue - severe edema, NO blisters, hard inelastic eschar - nerve endings have been destroyed, patient may not have pain
63
Deep full-thickness burn or fourth degree burn
- damage extends beyond the subcutaneous tissue into the muscle, tendon, or bone - black with hard, inelastic eschar, NO edema or blisters, NO pain at affected area d/t destroyed nerve endings
64
Parkland formula for fluid resuscitation for burns
Amount of fluid needed in first 24 hr = 4 mL LR x weight (kg) x % body burned (using rule of nines) NOTE: half the amount of fluid is given in the first 8 hours, and the other half of the fluid is administered over the next 16 hours
65
Nursing care for acute phase of burn
Provide wound care using a septic technique, elevated and immobilize area following skin graft surgery and monitor for signs of infection, administer antibiotics as ordered, take measures to prevent infection, assist with passive and active ROM to prevent contractures, ensure adequate nutrition (require additional calories and proteins to facilitate healing — may require TPN)
66
Key antibiotics for burns
- silver sulfadiazine: key side effect is transient neutropenia - mafenide acetate: penetrates eschar, risk for metabolic acidosis
67

71
Stage III of Lyme disease
- late stage; occurs months or years after initial infection - complications: arthritis, cognitive impairment, other neurological symptoms
72
Lyme disease diagnosis
Positive ELISA test, confirmed with western blot test
73
Lyme disease treatment
Antibiotics such as doxycycline, analgesics such as NSAIDs
74
Permethrin is used to treat
Head lice (pediculosis)
75
Prevention of head lice reinfestation
Wash clothes and linens in hot water, place items that cannot be washed in tightly sealed bag for 2 weeks, other household members should be checked and treated
76

78
5% permethrin for treatment of scabies education

79
S/S of Steven’s Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN)
Flu-like symptoms followed by painful blistering and peeling of skin typically beginning on face and chest
80
