The nurse is reviewing the client’s laboratory results. Based on a client’s serum digoxin level, the client is diagnosed with digoxin toxicity. Which action should the nurse expect to implement?

Begin cardioversion to stabilize heart rhythm: Cardioversion is not the appropriate intervention for digoxin toxicity. Digoxin toxicity can cause arrhythmias, but the initial action should be to assess and manage the underlying cause, rather than immediately proceeding to cardioversion. B) Give digoxin by another route to slow absorption: Slowing the absorption of digoxin is not the appropriate action for treating digoxin toxicity. Instead, the focus should be on managing the existing toxicity and preventing further absorption by withholding additional doses. C) Administer potassium to stabilize the heart rate: While potassium may be indicated as part of the treatment for digoxin toxicity, particularly if hypokalemia is contributing to the toxicity, it is not the initial action. The priority is to assess the client’s acid-base and electrolyte values to identify any abnormalities contributing to the toxicity. D) Check acid-base and electrolyte values: This is the correct action. Digoxin toxicity can be exacerbated by electrolyte imbalances, particularly hypokalemia, hypercalcemia, and hypomagnesemia. Therefore, assessing the client’s acid-base and electrolyte values is essential to identify and correct any abnormalities contributing to the toxicity. Once identified, appropriate interventions can be implemented to manage the toxicity and stabilize the client’s condition.
