Final answer:
The nurse can best support the patient by promoting weight loss to reduce joint stress and teaching low-impact exercises, balanced with rest and possibly using mobility aids for symptom improvement. Correct option is D. encourage the patient to consider weight loss to improve symptoms
Step-by-step explanation:
To best assist the patient in coping with her osteoarthritis and limited activity, the most comprehensive approach is to encourage the patient to consider weight loss to improve symptoms. Losing weight can substantially decrease the stress on weight-bearing joints, reducing pain and improving mobility, which can potentially allow the patient to engage in more outdoor activities, albeit with necessary adjustments for low impact.
Additionally, teaching the patient low-impact exercises like swimming, water aerobics, and biking, as well as pain management techniques, can help maintain joint mobility and improve the patient's quality of life. Encouraging a balance between rest and activity, and the use of assisted devices such as canes, also aids in joint stress reduction.
