Which action demonstrates proper care for a patient with a partial-thickness burn to the hand?

Removing rings prior to applying a dry sterile dressing is the best approach when caring for a patient with a partial-thickness burn to the hand. This is crucial because burns can lead to swelling of the affected area, and if rings or other tight items are not removed, they can constrict blood flow and exacerbate tissue damage. Swelling can occur rapidly in the context of a burn, so timely removal of rings is essential to prevent complications.

In addition, applying a dry sterile dressing afterward protects the wound from infection and further injury, providing a barrier that helps maintain a moist healing environment while not irritating the burn itself. Proper wound care helps support the healing process and decreases the risk of infection which is a key concern in burn management.
