Final answer:
For a deep cut on the wrist, applying a pressure bandage is crucial. It's imperative to monitor for signs of infection such as increased redness, swelling, and pain post-bandaging. Treating wrist tendinitis involves icing, medication, and rest, which differs from treating a cut.
Step-by-step explanation:
First Aid for a Deep Cut
If your friend has received a deep cut on her wrist, the appropriate action would be to B) Put a pressure bandage on the cut. This is to control the bleeding and to prevent infection. A band-aid (Option A) is generally not sufficient for deep cuts, and putting the wrist in ice water (Option C) could cause additional harm. After bandaging, it is essential to watch for increased redness, swelling, and pain which can be signs of infection.
In contrast, conditions like wrist tendinitis require a different approach, including icing the tender area, taking non-steroidal anti-inflammatory medication, and allowing for rest to heal properly. Treatment for wrist tendinitis should follow a healthcare professional's recommendation, and not the first aid steps for a deep cut.
Therefore, understanding the difference between various types of injuries and their respective treatments is crucial for optimal healing. For deep cuts, proper first aid followed by monitoring for infection signs can help ensure a safe and prompt recovery.
