A nurse is caring for a client that is newly prescribed with calcium carbonate supplements. Which of the following options is an indication for this medication?

A. Calcium carbonate does not treat hypoglycemia. It is used to address low calcium levels, not blood sugar levels. B. Calcium carbonate is not used to treat hypothyroidism. Hypothyroidism is treated with thyroid hormone replacement therapy (e.g., levothyroxine). C. Calcium carbonate is commonly used to treat hypocalcemia (low calcium levels in the blood) and to prevent bone loss in conditions such as osteoporosis. D. Calcium carbonate is not used to treat hyperkalemia (high potassium levels). Treatments for hyperkalemia may include medications like sodium bicarbonate or calcium gluconate, but not calcium carbonate.
