Integumentary Assessment

The skin is the largest organ you can assess without a single tool — and the one most likely to reveal systemic disease before labs come back. Are you reading it correctly?

Integumentary assessment evaluates skin, hair, nails, and mucous membranes using inspection and palpation. Examine systematically: color, moisture, temperature, texture, turgor, and integrity. Skin turgor is tested over the sternum or clavicle in adults (not the hand dorsum, which loses elasticity with age) — a return time greater than 3 seconds suggests dehydration. Color changes carry diagnostic weight: cyanosis signals hypoxemia, jaundice reflects bilirubin elevation (check the sclera first in dark-skinned patients), pallor suggests anemia or poor perfusion, and erythema indicates inflammation or infection. For patients with darker skin tones, assess color changes on the palms, soles, oral mucosa, conjunctivae, and nail beds — not just exposed skin surfaces. Document all lesions using standardized descriptors: type (macule, papule, vesicle, pustule), size in centimeters, shape, border, color, distribution pattern, and whether blanching occurs with pressure. Non-blanching lesions (petechiae, purpura) suggest bleeding under the skin and require urgent follow-up. Assess wound staging using depth of tissue involvement: Stage 1 is intact skin with non-blanchable erythema; Stage 2 involves partial-thickness loss exposing dermis. Nail clubbing suggests chronic hypoxia; capillary refill greater than 3 seconds indicates impaired peripheral perfusion.

Key Distinctions

Don't confuse skin turgor testing sites — the sternum or clavicle is reliable in older adults, while the hand dorsum gives false positives for dehydration due to age-related elasticity loss. Students mix up blanching (normal capillary response) with non-blanching (petechiae/purpura indicating possible coagulopathy or vasculitis). Stage 1 pressure injury is intact skin with non-blanchable redness — if the skin is broken, it's already Stage 2 or beyond.

Clinical Pearl

When the chart says 'skin assessed, intact,' you've documented nothing useful. Describe what you actually see: color, turgor, moisture, lesion characteristics. The skin tells a story — write it down.
