امرأة عمرها ٥٨ سنة بعد انقطاع الطمث، وقياس كثافة العظم عندها يدل على نقص فيها. أي نشاط تنصحها به الممرضة للمحافظة على العظام؟

A 58-year-old postmenopausal woman has low bone density on a DEXA scan. Which activity does the nurse recommend to protect her bones?

1. Seated stationary cycling
2. Swimming for a full hour every day
3. Brisk walking for 30 minutes on most days
4. Light stretching exercises at home only

Answer: C) Brisk walking for 30 minutes on most days. Bone strengthens with weight-bearing and resistance exercise such as walking, stair climbing and strength training. Swimming and cycling help the heart but do little for bone density, and stretching alone is not enough.
