Study Notes
Structure of the Skin
- Skin consists of three primary layers: epidermis, dermis, and subcutaneous layer.
- Epidermis: Outermost layer with sub-layers including:
- Stratum germinativum (basal cell layer)
- Stratum corneum (horny cell layer)
- Dermis: Composed of connective tissue (collagen) and elastic tissue.
- Subcutaneous Layer: Contains adipose (fat) tissue.
- Epidermal Appendages:
- Hair
- Sebaceous glands (produce oil)
- Sweat glands: Eccrine (regulate temperature) and Apocrine (related to odor).
- Nails
Function of the Skin
- Provides protection from external elements and pathogens.
- Aids in temperature regulation through sweat production.
- Facilitates sensory perception via nerve endings.
- Involved in identification and communication.
- Assists in wound repair and skin healing.
- Contribution to absorption and excretion processes.
- Synthesizes vitamin D upon sunlight exposure.
Developmental Considerations (Older Adults)
- Skin structures gradually atrophy with age, leading to:
- Loss of elasticity and collagen.
- Reduction of subcutaneous fat, resulting in thinner skin.
- Decreased functioning of sweat and sebaceous glands, increasing heat stroke risk.
- Higher susceptibility to skin diseases and psychological impacts of aging.
Cultural and Social Considerations
- Clinical manifestations of diseases may vary based on skin pigmentation and hair texture.
- Darker pigmentation offers a genetic advantage against skin cancer.
- Hormonal influences can alter the appearance of sexual skin areas.
- Environmental factors can affect sweat gland efficiency.
Subjective Data: Health History
- Important to assess previous skin conditions (like psoriasis, eczema).
- Ask about changes in pigmentation, moles, excess dryness/moisture, pruritus, hair loss, and nail changes.
- Consider environmental hazards, medication history, and self-care practices.
Health Promotion: Tanning and Skin Cancer Risks
- Prolonged UV exposure is a significant risk factor for skin cancer.
- High-risk groups include individuals with a history of skin cancer, fair skin, freckles, family history of skin cancer, and those using UV-sensitive medications.
- Usage of tanning beds poses potential health hazards.
Physical Examination Preparation
- Prepare adequate lighting and necessary equipment (penlight, gloves).
- External variables that could affect skin color should be noted.
Inspection Parameters
- Assess skin for color, temperature (hypothermia/hyperthermia), moisture levels, texture, and lesions.
Abnormal Skin Findings
- Recognize various shapes and configurations of skin lesions, such as annular, target, and linear.
- Classify lesions as primary (like macules, papules) or secondary (like crusts, scars).
Pressure Ulcers
- Develop over bony prominences due to impaired circulation or immobility.
- Risk factors include thin skin, decreased sensory perception, moisture, and poor nutrition.
- Assessed and staged based on depth from I (least severe) to IV (most severe).
Common Skin Lesions
- Observed conditions include primary contact dermatitis, tinea corporis, psoriasis, and herpes zoster.
- Malignant lesions such as basal cell carcinoma and malignant melanoma are of significant concern.
Abnormal Conditions of Hair and Nails
- Hair abnormalities include conditions like seborrheic dermatitis and alopecia.
- Nail conditions to note include paronychia, Beau's lines, and splinter hemorrhages.
- Nail assessment includes evaluation of shape, contour, and consistency.
Health Promotion Goals
- Empower individuals to gain control over and improve their health through education and lifestyle changes.
