The patient, your family member, will be in a hospital bed. The bed has rails on both sides, called side rails. The side rails remind the patient that they are in the hospital and need to rest. The nurses help the patient turn on their side and put pillows behind their back so they are comfortable. You may see a special bag hanging off the side of the bed. This bag is called a foley catheter; it is connected to a tube that goes into the bladder. It is used to measure the amount of fluid (urine) the patient voids (pees). The patient does not have to get up and go to the bathroom.
