An elderly patient with low dietary calcium and limited sun exposure has low serum calcium and secondary hyperparathyroidism. Which integrated intervention addresses the mineral and hormonal issues most effectively?

• A. Provide dietary calcium and vitamin D supplementation with monitoring, encourage safe sun exposure, and consider weight-bearing exercise to reduce bone loss and lower parathyroid hormone stimulation.
• B. Treat only with antiresorptive medications and tell the patient that dietary changes and vitamin D status are irrelevant to parathyroid hormone activity or bone mineralization.
• C. Prescribe a high-sodium diet to enhance calcium excretion and stimulate PTH release further because increased urinary calcium will signal the bone to harden more rapidly and correct deficiency.
• D. Advise complete avoidance of calcium-rich foods to force the parathyroid to upregulate permanently and thus increase bone mineral density through compensatory mechanisms without supplements.
