Family members can be as scared as any patient. All the kinfolk want is for their family member to be all right. Because family members usually have no medical training, they will feel that the situation is out of their control. This feeling breeds fear. And fear can breed an inordinate amount of Internet searching and half-baked medical knowledge that can create even more confusion.
The best way to deal with a scared family member is with empathy, politeness and respect. If you’re comfortable doing this, feel free to hug them, console them and answer their questions if possible. You might not know the answers, but you can try and find out for them.
Don’t be afraid to befriend the family. It will help them through their troubled time. Of course, don’t let scared family members get in the way of your pressing duties.
