Which nursing intervention is appropriate for managing digoxin toxicity?

Obtaining a digoxin level is a critical nursing intervention when managing digoxin toxicity because it helps determine the concentration of the drug in the patient's bloodstream. Digoxin has a narrow therapeutic index, meaning that the difference between therapeutic and toxic levels is slim. By measuring the digoxin level, healthcare providers can assess whether the patient is experiencing toxicity based on the current serum concentration of the drug.

If the level is significantly elevated, it can lead to appropriate interventions, which may include withholding the medication and initiating appropriate treatment for toxicity, such as administering digoxin-specific antidotes or supportive care. Monitoring digoxin levels ensures that patients receive safe and effective care, and it allows for informed clinical decision-making based on the actual drug concentration, rather than relying solely on clinical signs and symptoms of toxicity.

In contrast, the other interventions do not directly address the immediate need to evaluate the extent of digoxin toxicity. Encouraging physical activity could exacerbate symptoms in a patient who is already experiencing toxicity. Reducing fluid intake may be inappropriate in the context of managing digoxin levels, as hydration status can play a significant role in kidney function and drug clearance. Administering a high-fat diet could affect drug absorption and is not relevant to addressing toxicity. Thus, obtaining a dig
