Part I: Foundations
1. Nail Anatomy & Physiology
Nail Unit Structure
External Components:
- Nail Plate: Visible portion, composed of keratin
- Free Edge: Distal portion extending beyond fingertip
- Cuticle (Eponychium): Protective seal at nail base
- Nail Folds: Skin surrounding nail plate
- Lunula: Whitish crescent at nail base
Internal Components:
- Nail Matrix: Growth center beneath cuticle
- Nail Bed: Vascular tissue beneath nail plate
- Hyponychium: Tissue beneath free edge
- Nail Root: Embedded portion in nail groove
- Germinal Matrix: Produces nail cells
Memory Aid: “NAIL PARTS”
Nail Plate – Adherent to bed – Invested by folds – Lunula visible – Produced by matrix – Anchored at root – Regenerated continuously – Terminated at hyponychium – Sealed by cuticle
Clinical Pearl
The nail plate is a window to systemic health. Changes in color, texture, or growth patterns can indicate underlying cardiovascular, respiratory, or metabolic disorders.
2. Nail Growth & Development
Growth Characteristics
- Fingernails: 3-4 mm per month
- Toenails: 1-2 mm per month
- Complete renewal: 4-6 months (fingers), 12-18 months (toes)
- Growth rate factors: Age, health, season, hormones
Physiological Functions
- Protection: Shield finger/toe tips from trauma
- Sensation: Enhance tactile perception
- Function: Assist in grasping and manipulation
- Cosmetic: Contribute to appearance and self-esteem
Important Note
Trauma to the nail matrix can result in permanent nail deformities. Always assess for matrix involvement in nail injuries.
3. Nail Assessment Techniques
Systematic Assessment Approach
Step 1: Inspection
Examine nail color, shape, surface texture, and surrounding tissue under good lighting
Step 2: Palpation
Assess nail thickness, adherence to nail bed, and surrounding tissue temperature
Step 3: Function Testing
Evaluate capillary refill time and nail bed circulation
Step 4: Documentation
Record findings using standardized terminology and measurement
Assessment Mnemonic: “NAIL EXAM”
Note the shape – Assess the color – Inspect the surface – Look at surrounding tissue – Evaluate capillary refill – Xamine for abnormalities – Assess adherence – Measure thickness
Normal Findings
- • Smooth, firm nail plate
- • Translucent with pink undertone
- • Capillary refill < 2 seconds
- • Intact cuticles
- • No clubbing or ridging
- • Appropriate nail length
Abnormal Findings
- • Discoloration (yellow, green, black)
- • Thickening or brittleness
- • Ridging or pitting
- • Clubbing or spooning
- • Separation from nail bed
- • Surrounding inflammation
4. Normal vs. Abnormal Findings
Normal Variants
- Longitudinal ridges: Age-related, benign
- Leukonychia: Small white spots from trauma
- Splinter hemorrhages: Occasional, from minor trauma
- Racial variations: Pigmentation differences
Concerning Findings
- Clubbing: Cardiovascular/respiratory disease
- Koilonychia: Iron deficiency anemia
- Beau’s lines: Systemic illness
- Terry’s nails: Liver disease
Urgent Findings
- Melanonychia: Potential melanoma
- Sudden color changes: Infection or malignancy
- Painful swelling: Acute paronychia
- Dystrophic changes: Severe infection
Clinical Pearl: Capillary Refill Test
Press nail bed until blanched, release pressure, observe return to pink color. Normal refill time is < 2 seconds in adults, < 3 seconds in elderly. Prolonged refill may indicate poor circulation or shock.
Part II: Clinical Applications
5. Common Nail Disorders
Paronychia
Definition & Pathophysiology
Infection of the nail fold, commonly caused by Staphylococcus aureus or Streptococcus species. Results from breaks in the skin barrier around the nail.
Clinical Presentation
- • Acute: Pain, swelling, erythema, purulent drainage
- • Chronic: Thickened nail fold, minimal pain
- • May involve single or multiple digits
- • Warmth and tenderness to touch
Risk Factors
- • Nail biting or picking
- • Aggressive manicuring
- • Frequent hand washing
- • Diabetes mellitus
- • Immunocompromised state
Nursing Interventions
- • Warm soaks 3-4 times daily
- • Topical or systemic antibiotics
- • Drainage if abscess present
- • Patient education on prevention
Onychomycosis (Fungal Nail Infection)
Definition & Pathophysiology
Fungal infection of the nail plate, commonly caused by dermatophytes (Trichophyton rubrum), yeasts, or molds. Accounts for 40% of all nail disorders.
Clinical Presentation
- • Discoloration (yellow, brown, white)
- • Thickening and brittleness
- • Subungual debris
- • Nail separation (onycholysis)
- • Typically painless
Risk Factors
- • Advanced age
- • Immunosuppression
- • Diabetes mellitus
- • Peripheral vascular disease
- • Trauma to nail
- • Communal bathing facilities
Nursing Interventions
- • Fungal culture confirmation
- • Topical antifungal therapy
- • Oral antifungals for severe cases
- • Nail hygiene education
- • Environmental modifications
Ingrown Nails (Onychocryptosis)
Definition & Pathophysiology
Condition where nail edge grows into surrounding skin, causing pain, inflammation, and potential infection. Most common in great toes.
Clinical Presentation
- • Pain and tenderness
- • Erythema and swelling
- • Granulation tissue formation
- • Purulent drainage if infected
- • Difficulty wearing shoes
Risk Factors
- • Improper nail trimming
- • Tight-fitting shoes
- • Genetic predisposition
- • Nail trauma
- • Hyperhidrosis
Nursing Interventions
- • Conservative management: soaks, cotton placement
- • Proper nail trimming technique
- • Footwear modifications
- • Referral for surgical intervention
- • Infection prevention strategies
Disorder Memory Aid: “PIO”
Paronychia – Painful, purulent, proximal nail fold infection
Ingrown nail – Inward growth causing inflammation
Onychomycosis – Opportunistic fungal infection
6. Nursing Interventions
General Nail Care Protocol
Nail Care Assessment & Intervention Flowchart
→ Preventive Care
→ Therapeutic Care
→ Immediate Referral
Preventive Interventions
- Education: Proper nail hygiene techniques
- Trimming: Straight across, not too short
- Moisturizing: Cuticle and nail bed care
- Footwear: Proper fit and ventilation
- Environmental: Dry, clean conditions
- Nutrition: Adequate protein and vitamins
Therapeutic Interventions
- Soaking: Warm water with antiseptic
- Debridement: Removal of diseased tissue
- Topical therapy: Antifungal or antibiotic
- Systemic therapy: Oral medications
- Surgical referral: For severe cases
- Wound care: Proper dressing techniques
Clinical Pearl: Nail Trimming Technique
Use clean, sharp nail clippers. Cut nails straight across, then gently round corners with an emery board. Avoid cutting too short to prevent ingrown nails. For thick nails, soften with warm water first.
