My mother is 70 years old. She was undergoing treatment for bone TB for the last 13 months. She had also started walking but one day she fell and her hip bone broke. Then she underwent an operation. After that she developed a state of confusion. Sometimes she becomes normal for 2 or 3 days and then the same condition occurs again and she does not sleep at night. Please suggest a solution. Her serum sodium is 136 and serum potassium is 2.9 and hemoglobin is 11.2.
