A nurse is caring for an infant who has heart failure and a new prescription for digoxin.Which of the following findings should the nurse report to the provider?

Choice A reason: A weight loss of 0.25 kg (0.55 lb) may be within the range of normal fluctuation for an infant and may not necessarily warrant immediate reporting. However, it should be monitored closely. Choice B reason: Vomiting twice in 4 hours after receiving digoxin is a concerning finding. Digoxin has a narrow therapeutic range, and vomiting can lead to potential overdose. This should be reported to the provider for further evaluation. Choice C reason: A respiratory rate of 30/min may indicate increased work of breathing, which is a concern in an infant with heart failure. However, it is not specific to digoxin administration and may require intervention but not immediate reporting. Choice D reason: A heart rate of 130/min is within the range of normal for an infant, especially one with heart failure. This finding is not specific to digoxin administration and may not warrant immediate reporting.
