Notify the primary care provider if more than two consecutive doses are missed. 6. An 18-month-old with a congenital heart defect is to receive digoxin (Lanoxin) twice a day. The nurse should instruct the parents about which of the following?

1. Digoxin enables the heart to pump more effectively with a slower and more regular rhythm.

2. Signs of toxicity include loss of appetite, vomiting, increased pulse, and visual disturbances.

3. Digoxin is absorbed better if taken with meals.

4. If the child vomits within 15 minutes of administration, the dosage should be repeated.
