Prior to giving nail care, the CNA/Nurse Aide should check the chart to see if they can give nail care. Two situations when the CNA should not provide nail care: 1. When the patient or resident is on anticoagulation therapy to prevent blood clots. They are at a higher risk for bleeding, even from a small cut. 2. Diabetes means that healing from a wound will be slower, putting the patient or resident at risk for infection or developing severe wound ulcers.
