The nurse is teaching a postmenopausal client about osteoporosis prevention. The client reports that she smokes 2 packs of cigarettes a day and takes 750 mg calcium supplements daily. Which information should the nurse include when teaching this client about osteoporosis prevention?

Postmenopausal women need an intake of at least 1,500 mg of calcium daily.

Smoking cessation is more important than calcium intake in preventing osteoporosis.

Family history is more important than calcium intake in determining the occurrence of osteoporosis.
