Which symptom is NOT typically associated with digoxin toxicity?

• A. Confusion
• B. Nausea
• C. Vision changes
• D. Cough

Answer: (D)

Digoxin toxicity tends to show up in the GI system, the brain, and the eyes. Nausea, vomiting, and loss of appetite are common early signs, confusion or changes in mental status can occur with toxic levels, and visual disturbances such as blurred vision or yellow-green halos are classic. A cough, however, is not a typical feature of digoxin toxicity. It’s more often related to lung or heart failure symptoms (like fluid congestion) rather than a direct toxic effect of digoxin. So the symptom that doesn’t fit the usual toxic pattern is the cough.
