What is the therapeutic serum level range for digoxin that nurses should monitor?

The therapeutic serum level range for digoxin, which is a medication used primarily for heart conditions such as atrial fibrillation and heart failure, is indeed 0.5 to 2 ng/mL. Monitoring this range is crucial because levels outside of this range can indicate potential toxicity or inadequate therapeutic effect.

Digoxin works by affecting the sodium-potassium ATPase pump, leading to increased intracellular calcium and improved cardiac contractility, which is particularly beneficial in the management of heart failure. Maintaining the serum levels within the therapeutic range ensures that the drug provides the intended benefits while minimizing the risk of adverse effects, such as nausea, vomiting, and cardiac arrhythmias, which can occur if levels exceed the upper limit of the therapeutic range.

Therefore, understanding and monitoring the appropriate serum level for digoxin is essential for safe and effective patient care.
