Which of the following is a sign of Digoxin toxicity?

Blurred vision is a well-known sign of Digoxin toxicity, which can occur when the levels of the medication in the body become too high. Digoxin is commonly used to treat certain heart conditions, including atrial fibrillation and heart failure. The compound has a narrow therapeutic window, meaning that the difference between a therapeutic dose and a toxic dose is small.

Visual disturbances, such as blurred vision, may occur due to the effect of Digoxin on the central nervous system and its ability to alter the perception of visual stimuli. Patients experiencing toxicity might also report seeing halos around lights or changes in color vision, which directly relate to the interaction of Digoxin with various physiological processes.

While other symptoms can be associated with Digoxin toxicity, the specific neurological effect of blurred vision makes it a key indicator in identifying when a patient may be experiencing harmful levels of the medication. This knowledge is crucial for nurses when assessing patients treated with Digoxin and understanding the medication's side effects.
