Final answer:
A nurse aide should assist a stroke-recovering patient (C) on their weak side to provide necessary support and promote the use of weakened limbs during rehabilitation.
Step-by-step explanation:
When helping a client who is recovering from a stroke to walk, the nurse aide should assist on the patient's weak side. This is because the weak side is where the patient will need the most support and guidance.
The goal is to encourage the use of the weakened limbs to promote strength and coordination. This is consistent with the post-stroke rehabilitation process, which focuses on helping patients regain skills and functionality affected by the stroke.
