An infant with Tetralogy of Fallot (TOF) is having a hypercyanotic episode. Which nursing interventions should the nurse implement? (Select All that Apply.)

A. The knee-chest position increases systemic vascular resistance and helps relieve the hypercyanotic episode. B. Administering oxygen can help improve oxygen saturation and alleviate the cyanosis during a hypercyanotic episode. C. Albuterol is typically not used for hypercyanotic episodes; it's more useful for bronchodilation in asthma. D. Morphine sulfate may be used to decrease the respiratory effort and calm the infant during a hypercyanotic episode. E. Drawing blood for a serum hemoglobin is not an immediate intervention for a hypercyanotic episode. The focus should be on managing the episode itself.
