Final answer:
The functional position of the hand does not include MCP flexion.
Step-by-step explanation:
The answer is C) MCP flexion.
The functional position of the hand refers to the natural position of the hand when it is at rest and ready for use. In this position, the wrist is slightly extended, the MCP (metacarpophalangeal) joints are slightly flexed, and the fingers are slightly flexed and adducted.
Wrist extension (A), radial deviation (B), and CMC abduction (D) are all included in the functional position of the hand. Wrist extension refers to bending the hand back, radial deviation refers to moving the hand towards the thumb side, and CMC abduction refers to moving the thumb away from the other fingers.
