During a physical exam of the client's nails, the nurse depresses the nail edge to blanch and then releases it. This technique will allow the nurse to assess:
1. Capillary refill.
2. The client's nail bed.
3. How brittle the client's nails are.
4. If clubbing of the nail is present.
Capillary refill.
Rationale: The nail plate is translucent. To determine capillary refill, the nail edge is depressed to blanch and is released, noting the return of color. Capillary refill is usually documented as brisk, which is a normal response. Depressing the nail edge would have no effect on the nail bed. Brittle nails are diagnosed by looking at the distal plates of the nail to inspect for splitting and peeling of the nail. Clubbing is assessed by looking at the angle of the nail bed.
