What do I do if the hat won't stay on the patient's head?

If the hat won't stay on the patient's head, the hat either needs to be replaced with a new hat because the current hat has stretched out, or you need to replace the hat with a smaller hat.

Place a new hat of the same size on the patient's head. If this new hat still does not stay in place, you will need to replace it with a smaller size hat.
