Answer 1 is correct because the device is best applied after surgery and may be used for up to 6 weeks as prescribed. Answer 2 is incorrect because the device is used most of the time when in bed. Answer 3 is incorrect because this amount of flexion and extension are prescribed initially, progressing to 90 degrees of flexion with full extension, which is 0 degrees. Answer 4 is incorrect because the client will be assisted out of bed the evening of or day after surgery with a knee immobilizer, and prescribed weight-bearing.
