Final answer:
The nurse's first action should be to assist the client in learning to manage colostomy care, which accommodates independence and encourages patient empowerment despite limitations from arthritis.
Step-by-step explanation:
If a client is unable to independently perform colostomy care due to arthritis, the nurse should first offer to assist the client to learn to manage the care. This approach fosters independence and empowers the client, which is a fundamental aspect of holistic nursing care. It is important to respect the client's autonomy and ability to learn new skills, even with the presence of arthritis. This aid could involve introducing adaptive devices or techniques that consider the client's physical limitations. If the client is unable to independently manage after proper instruction and adaptation, the nurse can then explore other options such as arranging for home care services or inquiring about the availability of family members to assist. Another beneficial resource is suggesting that the client attend a colostomy self-help support group, as this can provide both practical advice and emotional support.
