A nurse is caring for a client who requires cold applications with an ice bag to reduce the swelling and pain of an ankle injury. Which of the following actions should the nurse take?

The correct answer is A: Allow room for some air inside the bag. This is important because when applying cold therapy, it's crucial to allow some air in the ice bag to prevent frostbite or skin damage from direct contact with the ice. This allows for proper insulation and prevents excessive cold exposure to the skin. Placing the bag directly on the skin (B) can lead to skin damage. Applying the bag for 30 min at a time (C) is correct, but ensuring there is air inside the bag is more crucial. Reapplying the bag 30 min after removing it (D) is not necessary as the skin needs time to recover.
