Final answer:
The nurse may have failed to meet the outcome by not involving the client in the care plan development.
Step-by-step explanation:
The action by the nurse that may have led to failure to meet the outcome is not involving the client in the care plan development. When designing a care plan to improve walking mobility, it is important to involve the client in the process. This helps to ensure that the plan is tailored to the client's specific needs and preferences.
By not involving the client, the nurse may have overlooked important factors that could affect the client's motivation to try the new strategies for ambulation. If the client feels their needs and preferences are not being considered, they may be less willing to engage in the plan.
To maximize the chances of success, the nurse should collaborate with the client, taking into account their goals, preferences, and any limitations they may have. This promotes a sense of ownership and motivation, increasing the likelihood that the client will be willing to try the strategies for improved walking mobility.
