Final answer:
The standard recommendation for ice application to reduce inflammation is 15 to 20 minutes per session, repeated several times a day. Use a barrier like a towel to protect the skin and allow time between applications for the skin to return to normal temperature. Correct option is B.
Step-by-step explanation:
The correct duration for applying ice to reduce inflammation is generally 15 to 20 minutes per application. Using ice can help reduce swelling and inflammation by constricting blood vessels, which reduces blood flow to the area. It is commonly recommended to apply ice immediately after an injury to reduce pain and swelling and continue with intermittent icing for the first 24-48 hours.
When applying ice, it should not be placed directly against the skin; instead, use a towel or cloth as a barrier to prevent frostbite or irritation. It is also important to allow the skin to return to normal body temperature between icing sessions, which usually takes about 45 minutes to an hour. Reapplying ice too quickly or leaving ice on too long can lead to tissue damage.
For an acute injury, the cycle of ice application may be repeated several times a day during the initial phase of healing. It is crucial to monitor the skin's response to the cold and discontinue icing if you notice any adverse reactions.
