Q. A 67-year-old female patient presents to the emergency department with confusion, lethargy, and hypothermia. On physical examination, she is found to have a reduced level of consciousness, a body temperature of 33°C, and generalized myxedema. Her laboratory workup reveals severe hyponatremia and hypoglycemia. The patient's history is significant for hypothyroidism, which has been poorly controlled over the past few months. What is the most appropriate management plan for this patient?
