RN Nursing · Cardiac Glycosides · Practice question
A nurse is providing teaching about digoxin administration to the parents of a toddler who has heart failure. Which of the following statements should the nurse include in the teaching?
-
"Repeat the dose if your child vomits within 1 hour after taking the medication."
-
"You can add the medication to a half-cup of your child's favorite juice."
-
✓
"Have your child drink a small glass of water after swallowing the medication."
-
"Limit your child's potassium intake while they are taking this medication."
Answer & explanation
Correct: "Have your child drink a small glass of water after swallowing the medication."
Having the child drink a small amount of water after taking digoxin helps ensure the full dose is swallowed and prevents oral residue. If the child vomits after a dose, the dose should NOT be repeated — doubling could cause toxicity. Digoxin should never be mixed into a large amount of food or drink because if the child doesn't finish it, the full dose is not received. A half-cup of juice is too large a volume and would risk incomplete dosing. Hypokalemia increases digoxin toxicity risk, so potassium intake should not be limited; adequate potassium is protective.
