Final answer:
A nurse would assist a client who can bear weight only on one leg by teaching them the 3 point gait for ambulating with crutches.
Step-by-step explanation:
The nurse would work with the client to use a 3 point gait when ambulating with crutches after surgery on his right leg if he is only allowed to bear weight on his left leg. This gait ensures the client's safety and stability by keeping the weight off the injured leg. The 3 point gait involves the client moving both crutches and the injured leg forward together, then the non-injured leg is moved forward.
