Question

Quizplus · Accepted Answer

Drug toxicity is common with digoxin due to its narrow therapeutic range. Many contributing factors (eg, hypokalemia) can cause toxicity. However, in the absence of other factors, potassium does not need to be increased just because a client is on digoxin. If the client also takes some other potassium-depleting medications, such as diuretics, potassium supplements may be needed. Signs and symptoms of digoxin toxicity include the following: Gastrointestinal symptoms (eg, anorexia, nausea, vomiting, abdominal pain) are frequently the earliest symptoms (Option B) Neurologic manifestations (eg, lethargy, fatigue, weakness, confusion) Visual symptoms are characteristic and include alterations in color vision, scotomas, or blindness Cardiac arrhythmias - most dangerous (Option A) Drug levels are frequently monitored until a steady state is achieved and when changes are expected, such as in clients with chronic kidney disease and electrolyte disturbances (eg, hypokalemia, hypomagnesemia). (Option C) Digoxin toxicity can result in bradycardia and heart block. Clients are instructed to check their pulse and report to the HCP if it is low or has skipped beats. Educational objective: Drug toxicity is common with digoxin due to its narrow therapeutic range. Drug levels are frequently monitored. Nonspecific gastrointestinal symptoms similar to gastroenteritis are common and can lead to serious cardiac arrhythmias if not recognized.
