Digoxin is a drug that leads to increases in potassium ion concentration in the interstitial fluid.Determine the condition that results from digoxin toxicity.

Question

Quizplus · Accepted Answer

Digoxin is a cardiac glycoside that inhibits the sodium-potassium ATPase pump, leading to an increase in intracellular sodium and a decrease in intracellular potassium. This leads to an increase in extracellular potassium concentration (hyperkalemia) and can cause toxicity in patients with impaired kidney function or those taking medications that also increase potassium levels. Symptoms of digoxin toxicity include nausea, vomiting, blurred vision, and cardiac arrhythmias.
