Emergency and doctor visits often require a great deal of waiting time. I have created a crisis bag that I keep by the door for those moments. Included are a current list of medications and dosages for my loved one, two bottles of water, snack bars, my own medications, a book (I prefer reading to TV) since often cell usage is prohibited and a small pad of paper and pen.
Waiting times, especially in an emergency room, can be as much as five to seven hours before your loved one is either dismissed or admitted to a room. Leaving your loved one for a break often happens just as the medical staff is ready to impart information about the situation. Having most of your needs tucked into one washable tote bag minimizes those critical break needs.
These tips and more are available in my book.
