Which of the following priority interventions should a nurse include in the care plan for a client experiencing myxedema coma? Select all that apply.

Rationale: A. Clients in myxedema coma are often hypothermic, lethargic, or obtunded and may be unable to safely swallow. Oral intake is not reliable and can increase the risk of aspiration, so nutrition and fluids are administered intravenously until the patient is stabilized. B. Myxedema coma can lead to respiratory depression, hypoventilation, and CO₂ retention. Supporting the airway and providing mechanical ventilation when needed is a priority intervention to maintain oxygenation and prevent respiratory failure. C. Patients often present with hypotension, hyponatremia, and dehydration. IV fluids help restore intravascular volume, maintain perfusion, and correct electrolyte imbalances, which are essential for stabilizing cardiovascular function. D. Myxedema coma can cause bradycardia, low cardiac output, and ECG changes. Continuous cardiac monitoring is critical because arrhythmias can develop rapidly and may be life-threatening. E. Myxedema coma is associated with severe hypothermia, not hyperthermia. Active cooling would worsen the patient’s condition. Instead, passive rewarming with blankets and a warm environment is appropriate. F. Thyroid hormone replacement is essential and life-saving in myxedema coma. IV administration is necessary because oral absorption may be unreliable due to decreased gastrointestinal motility or altered consciousness.
