The nurse would teach the mother of a boy with Tetralogy of Fallot that if the child suddenly becomes cyanotic and dyspneic, the mother should:
Place him in knee-chest position
Have him lie prone, being sure he can breathe easily
Have him lie supine with the head turned to one side
Place him in semi-fowler's position in an infant seat
The Correct Answer is A
A. The knee-chest position increases systemic vascular resistance, which helps to divert more blood to the pulmonary circulation, improving oxygenation in a child experiencing a "tet spell" or hypercyanotic episode.
B. The prone position does not help in relieving cyanosis and dyspnea in Tetralogy of Fallot.
C. The supine position with the head turned does not assist in improving oxygenation during a cyanotic episode.
D. The semi-Fowler's position may aid breathing but is less effective than the knee-chest position in managing cyanotic spells.
