A massage practitioner with a small cut on her index finger should:

Choosing to wear a finger cot to cover the cut is the most appropriate response for a massage practitioner in this situation. A finger cot is specifically designed to protect small cuts or wounds on the fingers while allowing the practitioner to continue working effectively. By wearing a finger cot, the practitioner helps to prevent infection and provides a barrier that protects both the wound and the client.

Using an antiseptic ointment may help initially, but it does not provide the necessary physical barrier or protection needed during a massage. Bandaging the entire hand could restrict movement and may not be practical for performing massage techniques effectively. Avoiding touch altogether would limit the practitioner's ability to provide services and may not be necessary if the cut is properly covered, maintaining hygiene and safety standards.
