A nurse is assessing a client who is taking digoxin to treat chronic heart failure.
Which of the following findings should indicate to the nurse that the client is developing digoxin toxicity?
Hearing loss.
Tachycardia.
Blurred vision.
Insomnia.
The Correct Answer is C
Choice A rationale:
Hearing loss is not a typical sign of digoxin toxicity. Digoxin toxicity primarily affects the visual system, leading to disturbances such as blurred or yellow-tinted vision. It can also cause various cardiac symptoms due to its effects on heart rhythm and contractility. Hearing loss is not a recognized symptom of digoxin toxicity.
Choice B rationale:
Tachycardia (fast heart rate) can be a sign of digoxin toxicity. Digoxin can cause arrhythmias and alter heart rate, which may lead to tachycardia. While this is a possible symptom, it is not as specific as other manifestations, such as visual disturbances.
Choice C rationale:
Blurred vision is a hallmark sign of digoxin toxicity. Digoxin can cause disturbances in color vision, such as seeing yellow or green halos around objects. Blurred vision is a significant indicator of digoxin toxicity and requires prompt medical attention.
Choice D rationale:
Insomnia is not a recognized symptom of digoxin toxicity. Digoxin toxicity primarily affects the cardiovascular and visual systems, leading to symptoms related to heart rhythm disturbances and vision changes. Insomnia is not a typical manifestation of digoxin toxicity.
