NCLEX RN Practice Question

Calcium is the chief mineral that hardens bone, and vitamin D is required for intestinal absorption and physiologic use of calcium. For adults over 65, evidence-based recommendations typically call for a daily total of about 1,000-1,200 mg calcium and 800 IU vitamin D, either from food or supplements, to help preserve bone density and decrease fracture risk. Although nutrients such as protein, magnesium, and potassium support overall musculoskeletal health, and iron and vitamin B12 are vital for hematologic and neurologic function, they are not highlighted as the primary focus of routine bone-health counseling for this population.
