The person has no understanding that it is unsafe for them to stand up when they are unable to weight bear due to a medical condition. They do not retain in their memory that it is unsafe for them to stand up on their own. Asking them to wait for assistance has poor compliance. When they are stopped from standing up they are likely to yell and engage in other negative behaviors. Work with the physical therapist on ways of getting the person upright and still comply with their non-weight bearing orders.
