Final answer:
A nurse should recommend calcium and vitamin D supplements to clients on long-term prednisone therapy for rheumatoid arthritis to help prevent bone density loss. A balanced diet and possibly B6 and potassium supplements should also be considered, but clients should always consult healthcare providers before starting any new supplements.
Step-by-step explanation:
A nurse instructing a client on long-term prednisone therapy for rheumatoid arthritis should recommend the intake of calcium and vitamin D supplements. Prednisone is a corticosteroid that can cause bone density loss, leading to osteoporosis. Vitamin D helps in the absorption of calcium, thus helping to maintain bone strength. Additionally, the nurse should educate the client on the importance of a balanced diet and possibly other supplements to support overall health, which may include vitamin B6 and potassium, as prednisone can also affect levels of these nutrients.
However, it is always essential for clients to consult with their healthcare providers before starting any supplements, as individual needs may vary and some supplements can interact with medications.
