Final answer:
The assistance level for a person who manages bladder control independently with the help of a device or medication is considered 'independent'.
Step-by-step explanation:
If a person requires a device, medication, or other collecting device for bladder control and can manage this without any assistance, then the assistance level is considered independent. Though the individual may rely on an aid for proper bladder functioning, the key factor here is the lack of need for assistance from another person in using these devices or medications.
