The nursing instructor is discussing digoxin-induced dysrhythmias. what risk factor would the instructor identify as increasing risk of dysrhythmia in a client taking digoxin?

Hypokalemia

Explanation:

The toxicity due to digoxin increases when metabolic disturbances such as hypokalemia occur.  Hypokalemia usually occur during the diuretic therapy and leads to electrolytic disturbances. These disturbances increase the sensitivity of the digoxin to produce toxicity. In such scenarios, even a small concentration of digoxin serum can prove to be toxic. Hypokalemia inhibits the sodium-potassium ATPase and even treatment with antibodies specific to digoxin can lead to hypokalemia
