What anticipatory guidance should you give to the parents of a child who must take digoxin?

A. Digoxin does not need to be given with food, and food may actually alter its absorption. It's best given at the same time each day, either with or without food, depending on the provider's recommendation. B. The heart rate threshold for holding digoxin in children is generally less than 90–110 beats/min in infants and less than 70 in older children, not 60 bpm, which is the adult guideline. C. Nausea and vomiting are early signs of digoxin toxicity. Parents should be taught to observe for these symptoms and report them immediately. D. If a child vomits after taking digoxin, the dose should not be repeated, as it is impossible to know how much was absorbed, and repeating could cause toxicity.
