Which of the following are appropriate nursing interventions for the patient in myxedema coma? (Select all that apply)

A. Monitor airway and respiratory effort: Myxedema coma can depress respiratory function, leading to hypoventilation and hypoxia. Continuous monitoring of airway patency, oxygenation, and respiratory rate is essential to prevent respiratory failure. B. Administer levothyroxine as prescribed: Thyroid hormone replacement is critical in treating myxedema coma. IV administration is preferred initially due to impaired gastrointestinal absorption in severe hypothyroidism. Timely dosing helps restore metabolic and cardiovascular stability. C. Encourage the intake of foods high in sodium: Sodium intake is not a priority intervention and may be harmful if fluid retention or hyponatremia is present. Electrolyte management is guided by laboratory values rather than routine dietary sodium encouragement. D. Monitor urine osmolality: Urine osmolality monitoring is more relevant in disorders of water balance, such as SIADH, rather than in myxedema coma. Fluid status assessment focuses on volume overload or deficit and serum electrolytes. E. Initiate passive rewarming interventions: Patients with myxedema coma often present with hypothermia. Passive rewarming (blankets, warm environment) avoids rapid shifts in circulation that could occur with active external heating, reducing the risk of cardiovascular instability.
