How do nurses assess for digoxin toxicity?
An additional nursing intervention to guard against digoxin toxicity is to assess the apical pulse for one full minute before administering digoxin. Hold the next dose and contact the physician if the apical pulse is less than 60 or more than 120 beats per minute.

Why does hypokalemia cause digoxin toxicity?
In states of hypokalemia, or low potassium, digoxin toxicity is actually worsened because digoxin normally binds to the ATPase pump on the same site as potassium. When potassium levels are low, digoxin can more easily bind to the ATPase pump, exerting the inhibitory effects.
