Final answer:
For a client with right-sided weakness after a stroke, a standard walker offers the best stability for walking, due to its wide base of support.
Step-by-step explanation:
The nurse should suggest that the client with right-sided arm and leg weakness from a stroke use a standard walker to provide the best stability for ambulating. A standard walker provides a wide base of support, which can compensate for weaknesses and increase stability while walking. It is important when dealing with impaired mobility to use devices like a walker to prevent falls and allow for greater independence.
