Final answer:
Digitalis toxicity in children can cause nausea, vomiting, CNS changes such as agitation and anxiety, abnormal heart rhythms, low blood pressure, and muscular problems. These symptoms necessitate immediate medical intervention.
Step-by-step explanation:
The signs that indicate a child may be experiencing digitalis toxicity include a variety of symptoms such as nausea, vomiting, abdominal pain, and CNS changes, which can encompass agitation, anxiety, and sleep problems. In addition, certain cardiac symptoms are common, such as abnormal heart rhythms (arrhythmias). Another critical sign of digitalis toxicity, particularly in the pediatric population, is low blood pressure. Muscular problems, which can manifest as weakness or fatigue, can also be a symptom of digitalis toxicity.
A child with these symptoms warrants immediate medical evaluation to confirm the presence of digitalis toxicity and to initiate appropriate treatment, which may include medication adjustment and monitoring of electrolyte levels, especially potassium. This is due to the fact that both hypo- and hyperkalemia can have significant impacts on the heart and overall health.
