Final answer:
The correct way of using a cane involves holding it with the hand on the stronger side to effectively widen the base of support and improve stability. The individual should move the cane forward first before the affected leg.
Step-by-step explanation:
The nurse evaluating a client using a cane would consider that the client is using the cane appropriately if the client holds the cane with the hand on the stronger side (option a). This is because using the cane with the stronger side helps to provide better support and balance for the body, compensating for the weakness on the affected side. The individual should move the cane forward first, followed by a step with the affected leg, keeping the cane relatively close to the body for stability. A properly used cane thus widens the base of support and can help to lower the center of gravity, improving the user's stability.
