Which parent statement indicates a therapeutic effect of digoxin in an infant with heart failure?

• A. My baby is breathing easier than they used to
• B. My baby is eating better
• C. My baby has fewer episodes of crying
• D. My baby drinks more formula

Answer: (A)

Digoxin works by increasing the heart’s contractility, which boosts cardiac output. In an infant with heart failure, the improved pumping reduces pulmonary congestion, making breathing easier. That direct improvement in respiratory status is the clearest sign that the medication is having a therapeutic effect. While better feeding or formula intake can occur as the child feels better, they’re less specific indicators of digoxin’s action.
