Which step is part of applying a sling and binder?

• A. Apply a cast
• B. Get consent
• C. Check blood pressure
• D. Use a tourniquet

Answer: (B)

Consent before providing care is essential when immobilizing a limb with a sling and binder. Before touching or adjusting the injured arm, you should explain what you plan to do and ask for the person’s permission. This respects their autonomy and is the ethical standard in first aid. If they agree, you proceed to position the arm, support it with a sling, and secure the binder to limit movement and protect the injury. If the person cannot respond, you provide care under implied consent to prevent further harm and to stabilize the injury.

The other options don’t fit because applying a cast is a medical treatment performed later by professionals, not a basic first aid step; checking blood pressure is part of a broader assessment, not a specific step in applying a sling and binder; and using a tourniquet is reserved for controlling severe bleeding, not immobilizing a limb.
