Question

A 3-month-old infant with uncorrected tetrology of Fallot (TOF) is awaiting surgical repair. While his diaper is being changed, the baby starts crying and breathing rapidly. The infant becomes cyanotic and a code is called. Vital signs are P 160, BP 50/30, SpO 2 60%. Which of the following interventions would be LEAST appropriate at this time?

A. Administering sodium bicarbonate
B. Administering morphine
C. Administering epinephrine
D. Administering phenylephrine
E. Administering esmolol

Answer 1

Administering sodium bicarbonate would be the least appropriate intervention in this situation of a cyanotic infant with uncorrected tetralogy of Fallot. Other interventions such as administering supplemental oxygen or initiating ventilation would be more appropriate.

Step-by-step explanation:

The LEAST appropriate intervention in this situation would be administering sodium bicarbonate. Sodium bicarbonate is typically used to treat metabolic acidosis, but in this case, the infant's acidosis is likely due to poor oxygenation rather than metabolic causes. Therefore, correcting the underlying cause of poor oxygenation, such as administering supplemental oxygen or initiating ventilation, would be more appropriate.
