A nurse is collecting data from an adolescent client who takes digoxin.
The nurse should monitor the client for which of the following adverse effects?
A.
Yellow Sclera.
B.
Blurred vision.
C.
Frequent swallowing.
D.
Bleeding gums.
The correct answer and Explanation is :
The correct answer is B. Blurred vision.
Explanation:
Digoxin is a cardiac glycoside commonly used to treat heart failure and atrial fibrillation. While it can be highly effective in managing these conditions, it also has a narrow therapeutic index, meaning that the difference between an effective dose and a toxic dose is small. Therefore, careful monitoring for adverse effects is crucial.
Blurred vision is a notable adverse effect of digoxin toxicity. Patients may experience various visual disturbances, including blurred vision, yellow or green vision (xanthopsia), or halos around lights. These symptoms occur because digoxin affects the electrical conduction system of the heart and can also impact the central nervous system, including the visual pathways.
In addition to blurred vision, other symptoms of digoxin toxicity may include gastrointestinal symptoms (nausea, vomiting, diarrhea), neurological symptoms (confusion, drowsiness), and cardiac symptoms (arrhythmias). Adolescents may be particularly vulnerable to toxicity due to factors such as varying body size and hydration status, which can affect drug concentrations in the bloodstream.
The other options provided—yellow sclera, frequent swallowing, and bleeding gums—are not commonly associated with digoxin. Yellow sclera may indicate liver dysfunction or jaundice, which is not a direct effect of digoxin. Frequent swallowing may suggest a gastrointestinal issue or an unrelated condition, and bleeding gums are more typically associated with conditions affecting platelet function or gingival health rather than digoxin use.
Given the potential for serious adverse effects, it’s essential for nurses to educate patients and caregivers about the signs of digoxin toxicity and to monitor for these symptoms regularly. Early recognition of blurred vision and other warning signs can lead to prompt intervention and prevent complications.
