Final answer:
For a child with hemophilia experiencing acute hemarthrosis, ice application and elevation of the affected joint are essential steps in reducing pain and swelling. Compression may be used after bleeding has stopped.
Step-by-step explanation:
When teaching a parent how to care for a child with hemophilia who is experiencing acute hemarthrosis, several instructions should be included. One key instruction is: (A) Apply ice packs to the affected joint for 15-20 minutes at a time, every 2-3 hours to help reduce swelling and pain.
Additional steps that are recommended include (B) elevation of the affected joint above the level of the heart to decrease blood flow to the area, which can reduce swelling. Compression, such as a compression bandage, can be beneficial once active bleeding has stopped. It is important to note that applying heat is generally not recommended immediately after the injury, as it can increase bleeding and swelling.
