Discharge teaching for a 3-month-old infant with a cardiac defect who is receiving digoxin should include which information?

• A. Give the medication at regular intervals
• B. Mix the medication with a small volume of breast milk or formula
• C. Repeat the dose if vomiting occurs immediately after administration
• D. Notify the healthcare provider of poor feeding or vomiting

Answer: (A)

Digoxin has a narrow therapeutic window, so keeping a steady level in the blood is essential to improve heart function while avoiding toxicity. Giving the medication at regular intervals ensures the infant maintains therapeutic drug exposure and reduces the risk of subtherapeutic effects or toxic peaks and troughs. In a 3-month-old, small changes in timing can significantly affect how the heart responds, so caregivers should administer the dose exactly as prescribed, at the same times each day. If the infant vomits, do not repeat the dose automatically—this can lead to overdose. Instead, contact the healthcare provider for guidance. Ongoing signs such as poor feeding or vomiting, as well as any unusual sleepiness or slowed heart rate, should also be reported to the clinician, since these can indicate possible toxicity or other concerns. It’s also important to monitor the infant’s pulse before dosing and hold the medication if the heart rate is below the clinician’s threshold. Keeping a consistent schedule and promptly reporting concerning symptoms helps ensure the medication works safely.
