A nurse is teaching the parent of a preschool-age child about digoxin administration. Which of the following statements by the parent indicates an understanding of the teaching?

A. "I will take my child's pulse for 30 seconds before giving the medication.": Checking the pulse for 1 full minute is crucial before administering digoxin, especially in preschool-age children, because the medication can slow the heart rate. If the pulse is below the prescribed threshold (usually <90–100 bpm in young children), the dose should be held. B. "I will mix the medication in a glass with 4 ounces of orange juice.": Digoxin can be given with a small amount of liquid, but large volumes of juice are not recommended because excessive liquid may make it difficult for the child to take the full dose. Also, certain juices may interact with absorption; using a small amount of water or juice is safer. C. "I will repeat the dose if she vomits after taking the medication.": Repeating a dose after vomiting is unsafe because it can result in digoxin toxicity, especially in young children. The parent should contact the healthcare provider for guidance instead of administering a second dose. D. "I will tell my child to brush her teeth after she takes this medication.": Digoxin elixir is prepared in a high-sugar syrup base to make it more palatable for children. Frequent administration of this sticky, sugary liquid can lead to tooth decay and dental carries. Brushing the teeth (or rinsing the mouth in younger infants) after each dose is an essential measure.
