An OT practitioner is working with a client experiencing proximal upper extremity weakness as a result of polymyositis. The client wants to be able to feed himself while sitting up in his wheel-chair
The therapist has set up a MAS , but the client is having difficulty flexing his elbow enough to reach his hand to his mouth. Which adjustment can the therapist make to facilitate this motion?
A. Lower the semireclining mount on the wheelchair upright.
B. Move the rocker arm more distally on the forearm support.
C. Roll the semireclining mount outwardly.
D. Move the rocker arm more proximally on the forearm support.
ANS: B
Adjusting for vertical motion such as elbow flexion and extension is done by moving the rocker arm position on the forearm support. Moving the rocker arm more distally will shift more of the arm's weight proximally to facilitate elbow flexion, whereas moving the rocker arm more proxi-mally will shift weight to facilitate extension. Lowering the mount on the wheelchair upright would bring the hand further away from the mouth. Rolling the mount influences horizontal mo-tion, not vertical motion.

Answer the following statement(s) true (T) or false (F)
1. An audible timer is equipped on a fluoroscopic unit to sound off when 5 minutes of fluoroscopic time (actual time of radiation exposure to the patient) has elapsed. 2. Brightness control or image illumination is maintained as the kVp and mA self-adjust during the fluoroscopic procedure. 3. This low range of kVp is attributable to the increase in time (minutes) of actual radiation. 4. The fluoroscopic system is a fixed unit consisting of several components working together to provide static images for viewing. 5. Automatic gain control (AGC) refers to fluoroscopic image brightness.
