Digoxin toxicity is a serious concern, especially in older adults due to their age-related physiological changes. Possible findings that a nurse should recognize as manifestations of digoxin toxicity in an older adult include anorexia, nausea, vomiting, and general weakness, which may lead to dehydration, electrolyte abnormalities and poor drug metabolism. These signs are due to the onset of cardiac arrhythmias, as well as the exacerbation of current digestive, liver, kidney conditions or diseases. The finding "anorexia" is the best answer as the other choices, hypertension, bradycardia, and hyperglycemia, can be symptoms of other conditions.
