Study Notes
Skin, Hair, and Nails Assessment
- Skin Layers: The skin has three layers: epidermis (basal and horny cell layers), dermis (connective tissue, glands, vessels), and subcutaneous tissue (fat, vessels, nerves).
- Hair Types: Fine, faint vellus hair and darker, thicker terminal hair.
- Nail Structure: Nails are hard keratin plates with visible parts like the nail plate, lunula, and cuticle.
- Skin History Questions: History of skin conditions, changes in pigmentation, moles, dryness/moisture, itching, rashes, lesions, hair loss, nail changes, medications, environmental/occupational factors, and sun protection.
- Skin Color Changes:
- Pallor: Reduced oxygenated hemoglobin (anemia).
- Erythema: Increased blood flow (fever, inflammation).
- Cyanosis: Decreased oxygen in blood.
- Jaundice: Excess bilirubin (liver dysfunction).
- Malignant Lesions: Melanoma, basal cell carcinoma, squamous cell carcinoma.
- Non-Malignant Lesions: Freckles, skin tags, seborrheic keratosis.
- Common Lesions: Macules, papules, pustules, vascular lesions.
- ABCDE for Skin Assessment:
- A: Asymmetry
- B: Border irregularity
- C: Color variation
- D: Diameter greater than 6mm
- E: Evolution
- Skin Assessment: Inspect color, texture, lesions, and palpate for temperature/moisture.
- Hair Assessment: Assess texture, distribution, and scalp condition.
- Nail Assessment: Check for shape, color, and capillary refill.
- Skin Variations (Age):
- Very young: Thin, permeable, underdeveloped temperature regulation.
- Healthy adults: Thick, resilient, sebaceous glands active.
- Older adults: Thin, less elastic, dry, prone to injury (loss of collagen, sweat glands, vascularity).
