What digoxin level is considered toxic?

What digoxin level is considered toxic?

• A. Over 1.5
• B. Over 2.0
• C. Over 2.5
• D. Over 3.0

Answer: (B)

The digoxin level considered toxic is anything over 2.0 ng/mL. Digoxin is a cardiac glycoside used primarily to treat heart failure and atrial fibrillation. While therapeutic levels generally range from 0.5 to 2.0 ng/mL, levels above 2.0 ng/mL indicate a risk for toxicity. When digoxin levels exceed this threshold, patients may experience severe side effects such as nausea, vomiting, confusion, visual disturbances (like yellow-green halos), and bradycardia, which can lead to serious cardiac complications. Monitoring digoxin levels is critical, especially in populations who are more sensitive to its effects, such as the elderly or those with renal impairment. Understanding the toxicity level is key for safe nursing practice, as early recognition and intervention can prevent potentially serious health outcomes. Digoxin toxicity must be addressed promptly, often involving stopping the medication and providing supportive care as necessary. Following these guidelines helps ensure patient safety while managing their cardiovascular conditions effectively.
