Chapter 27 Care of Patients with Skin Problems

Xerosis (Dryness): 

Xerosis (Dryness) A common problem among older patients Fine flaking of the stratum corneum Generalized pruritus Scratching may result in secondary skin lesions, excoriations, lichenification, and infection

Collaborative Management: 

Collaborative Management Nursing interventions aim to rehydrate the skin and relieve itching. Bathing with moisturizing soaps, oils, and lotions may reduce dryness. Water softens the outer skin layers; creams and lotions seal in the moisture provided by water.

Pruritus (Itching) : 

Pruritus (Itching) Pruritus is caused by stimulation of itch-specific nerve fibers at the dermal-epidermal junction. Itching is a subjective symptom similar to pain. “ Itch-scratch-itch ” cycle. Cool sleeping environment is helpful. Fingernails should be trimmed short. Antihistamines. Topical steroids.

Sunburn : 

Sunburn First-degree, superficial burn Cool baths Soothing lotions Antibiotic ointments for blistering and infected skin Topical corticosteroids for pain

Urticaria (Hives): 

Urticaria (Hives) Urticaria — presence of white or red edematous papules or plaques of varying sizes Removal of triggering substances Antihistamines helpful Avoidance of overexertion, alcohol consumption, and warm environments, which can worsen symptoms

Trauma : 

Trauma Phases of wound healing: Inflammatory phase Fibroblastic or connected tissue repair phase Maturation or remodeling phase

Process of Wound Healing : 

Process of Wound Healing

Process of Wound Healing (Cont’d): 

Process of Wound Healing (Cont ’ d) First intention resulting in a thin scar Second intention (granulation) and contraction—a deeper tissue injury or wound Third intention (delayed closure)—high risk for infection with a resultant scar

Partial-Thickness Wounds: 

Partial-Thickness Wounds Involve damage to the epidermis and upper layers of the dermis Heal by re-epithelialization within 5 to 7 days Skin injury immediately followed by local inflammation

Re-epithelialization: 

Re-epithelialization

Full-Thickness Wounds: 

Full-Thickness Wounds Damage extends into the lower layers of the dermis and underlying subcutaneous tissue. Removal of the damaged tissue results in a defect that must be filled with granulation tissue to heal. Contraction develops in healing process.

Pressure Ulcer: 

Pressure Ulcer Tissue damage caused when the skin and underlying soft tissue are compressed between a bony prominence and an external surface for an extended period. Mechanical forces that create ulcers: Pressure Friction Shear

Shearing Force : 

Shearing Force

Identification of High-Risk Patients: 

Identification of High-Risk Patients Mental status changes Independent mobility Nutritional status Incontinence

Pressure-Relieving Techniques: 

Pressure-Relieving Techniques Adequate pressure relief key to prevention of pressure ulcers Capillary closing pressure Pressure-relief products and devices Positioning

Wound Assessment: 

Wound Assessment Pressure ulcers and their features are classified and assessed in four stages: Stage I Stage II Stage III Stage IV

Wound characteristics: 

Wound characteristics Arterial Diabetic Venous

Four Stages of Pressure Ulceration : 

Four Stages of Pressure Ulceration

Wound Assessment: 

Wound Assessment Location Size Color Extent of tissue involvement Cell types in the wound base and margins Exudate Condition of surrounding tissue Presence of foreign bodies

Wound Contamination/Wound Infection: 

Wound Contamination/Wound Infection A wound that is exposed is always contaminated but not always infected. Contamination is the presence of organisms without any manifestations of infection. Wound infection is contamination with pathogenic organisms to the degree that growth and spread cannot be controlled by the body ’ s immune defenses.

Herpes Simplex Virus (Cont’d): 

Herpes Simplex Virus (Cont ’ d) Herpetic whitlow—a form of herpes simplex infection occurring on the fingertips of medical personnel who have come in contact with viral secretions

Viral infections: 

Viral infections

Herpes Zoster/Shingles: 

Herpes Zoster/Shingles Caused by reactivation of the dormant varicella-zoster virus in patients who have previously had chickenpox. Multiple lesions occur in a segmental distribution on the skin area innervated by the infected nerve. Eruption lasts several weeks. Postherpetic neuralgia occurs after lesions have resolved.

Fungal Infections (Dermatophyte): 

Fungal Infections (Dermatophyte) Tinea pedis Tinea manus Tinea cruris Tinea capitis Tinea corporis Candida albicans

Interventions Skin care with proper cleansing Isolation Precautions Drug therapy

Skin Care : 

Skin Care Bathe daily with an antibacterial soap. Remove any pustules or crusts gently. Apply warm compress twice a day to furuncles or areas of cellulitis. Apply Burow's solution to viral lesions. Avoid excessive moisture. Ensure optimal patient positioning.

Drug Therapy for Skin Disorders : 

Drug Therapy for Skin Disorders Antibacterial drugs Antifungal drugs Anti-inflammatory drugs

Cutaneous Anthrax:
