Contagious superficial skin infection caused by staphylococci, streptococci, or multiple bacteria. Commonly seen on face or extremities. Begins with small, red macules, which quickly become discrete, thin-walled vesicles that rupture and become coved with a honey-yellow crust. Topical antibacterial therapy; systemic antibiotics if infections are widespread. **Contact precautions. Educate pt and family members to bathe at least once daily with bactericidal soap. Good hygiene to prevent infection transmission. Avoid contact with other people until lesions heal.

Orbital & Ocular Trauma: Lacerations

Corneal lacerations are an ocular emergency. DO NOT remove penetrating object. IV antibiotics and surgery.

Fracture Complications

Crush Syndrome: external crush injury that compresses one or more compartments in the leg, arm or pelvis. May cause hypovolemia, hyperkalemia, muscle weakness/pain, dark brown urine. Hypovolemic shock: common with pelvic fractures or open femoral fractures. VTE: common complication of lower extremity trauma or surgery. DIC: triggered by massive trauma.

Rheumatoid Arthritis Nursing Interventions/Pharmacology

DMARD 1. Methotrexate: increased risk for infection, liver toxicity and birth defects. 2. Leflunomide: increased liver enzymes and birth defects. 3.

Typanoplasty & Stapedectomy Pre/Postoperative

Preoperative: prevent infection; ear irrigation to restore normal pH. Operative procedure: local anesthesia normally used. Postoperative: 1. Ear canal packing causes temporary hearing loss. 2. Prevention of ear infection or trauma. 3. Supine position with the operative ear facing up. 4. Assess for facial nerve damage or weakness after Stapedectomy (asymmetric appearance, drooping on the affected side, decreased lateral gaze on the affected side, slurred speech, difficulty swallowing, changes in facial perception). 5. Ensure safety.

Total Hip Replacement (Total Hip Arthroplasty): Postoperative I

Prevent hip dislocation, correct positioning AT ALL TIMES. 1. Supine with head slightly elevated, keep affected leg in neutral position and abduction splint/pillows placed between legs to prevent adduction beyond midline of body. 2. Avoid flexing hips more than 90º. Hips should be higher than knees while sitting. 3. DO NOT sit or stand for prolonged period. DO NOT bend forward when seated in chair. DO NOT cross legs beyond body midline. DO NOT bend at the waist. 4. DO NOT twist body when standing. Avoid stress to new hip joint for the first 8-12 weeks, when the risk of dislocation is the highest. 5. Keep the operative hip in abduction when turning the patient in bed to the unaffected side. Avoid turning the patient to the affected side unless specified by surgeon. 6. Use assistive/adaptive devices e.g. high-seat chairs with arm rests, semi-reclining wheelchairs and raised toilet seats. 7.

Promote ambulation: OOB within a day after surgery (limited flexion maintained); assistive devices (walker, crutches). Can resume routine ADLs by 3 months.

Amputation: Collaborative Care

Psychosocial preparation if possible. Postoperative: 1. Assess tissue perfusion and managing pain are priorities. 2. Promote wound healing: wear closed rigid cast dressing or an elastic residual limb shrinker. 3. If the cast or elastic dressing comes off, wrap the residual limb with an elastic compression bandage IMMEDIATELY. Prevent hemorrhage: place large tourniquet at the bedside. Apply tourniquet to the residual limb immediately if excessive bleeding occurs. Prevent skin breakdown: wash and gently dry residual limb at least twice daily. Promote body image and prepare for prosthesis.

Brachytherapy: Radionuclide IV Isotopes & Sealed Implants

Systemic administration of radionuclide (e.g. IV Isotopes, Radioactive Iodine-131). Excreta IS radioactive and should not be directly touched by others. Take precaution and do NOT share toilet. Radioactive Sealed Implants: Excreta is NOT radioactive, but the person IS. 1. Assign patient private room/bath. Place a caution sign on the door of the patient's room, keep door closed. 2. Wear dosimeter badge when caring for the patient (measures exposure to radiation). 3. Wear lead apron while providing care to provide protection; do not face back towards the patient. 4. Pregnant staff should NOT be allowed to care for the patient. 5. Do NOT allow pregnant visitors or children <16 y.o. Limit visit to 30 minutes per day. 6. Save dressings/linen in the patient's room until the radioactive source is removed. After the radioactive source is removed, dispose of dressings/linen. 7. If the implant is dislodged, use long-handled forceps to retrieve the source and deposit into lead container. NEVER touch the radioactive source w/ bare hands.

Fractures: Skin Traction - Buck's Extension

To decrease painful muscle spasms and promote immobilization. *Weight is limited to 4.5-8 pounds on an extremity or 10-20 pounds on pelvis to prevent skin injury. Body weight and bed position adjustments provide counter-traction. Remain supine, avoid turning side to side. Patient may shift position slightly with overhead trapeze. Complications: 1. Skin breakdown: remove foam boots three times a day w/ second person supporting extremity during skin care; use static mattress. 2. Nerve damage: monitor foot drop (difficulty lifting front of foot). 3. Circulatory impairment: assess circulation of the foot every 15-30 minutes then every 1-2 hrs. Foot exercises every hr when awake.
