Which physical finding is commonly associated with Tetralogy of Fallot?

Explanation:
Chronic low oxygen levels from the right-to-left shunt in Tetralogy of Fallot commonly cause clubbing of the fingers. The reduced pulmonary blood flow leads to ongoing systemic hypoxemia, and over time this hypoxia drives tissue changes in the digits, producing the characteristic clubbing. Kayser-Fleischer rings are a sign of Wilson disease and aren’t related to TOF. Peripheral edema isn’t typical in TOF, since the main issue is inadequate pulmonary circulation rather than venous congestion; the murmur in TOF is usually a harsh systolic murmur from RV outflow obstruction, not an absent sound.
