Final answer:
A nurse anticipating the discharge of an infant with tetralogy of Fallot may require a pulse oximeter, a portable suction machine, and a cervical collar.
Step-by-step explanation:
The nurse anticipates the need for the pulse oximeter, which is a device used to measure the oxygen saturation level in the infant's blood. This is important because infants with tetralogy of Fallot may have low levels of oxygen in their blood due to congenital heart defects. By monitoring the oxygen saturation, the nurse can ensure that the infant is receiving enough oxygen.
Tetralogy of Fallot is a heart condition that involves four defects, including a ventricular septal defect (VSD), pulmonary stenosis, overriding aorta, and right ventricular hypertrophy. These defects can lead to a decrease in oxygen supply to the body. The pulse oximeter helps the nurse assess the infant's condition and adjust the treatment accordingly.
