When checking a victim, what is an important question to ask regarding their medical history?

Asking about allergies is crucial when checking a victim because allergies can significantly impact the medical care they receive. Allergic reactions can range from mild to life-threatening, and knowing if the victim has any allergies helps responders avoid administering substances that could trigger a reaction. For example, if the victim is allergic to certain medications, providing those could lead to serious complications. Furthermore, if the victim is unable to provide this information themselves, knowing about allergies becomes even more vital in guiding treatment decisions. Overall, understanding a victim's allergies is a key part of ensuring their safety and providing effective care.
