The nurse is caring for a pediatric patient receiving digoxin therapy. Which assessment finding would indicate digoxin toxicity?
Pedal edema.
Cardiac arrhythmias.
Circumoral cyanosis.
Infrequent voiding.
The Correct Answer is B
Choice A rationale:
Pedal edema is not indicative of digoxin toxicity. Digoxin toxicity primarily affects the heart's electrical activity and rhythm, not fluid accumulation in the extremities.
Choice B rationale:
Cardiac arrhythmias are a hallmark sign of digoxin toxicity. Digoxin can lead to various types of arrhythmias, such as atrial tachycardia, atrial fibrillation, and ventricular ectopy. This occurs due to the drug's effects on altering the electrical conduction in the heart.
Choice C rationale:
Circumoral cyanosis is not a typical sign of digoxin toxicity. This symptom might be seen in conditions like methemoglobinemia or respiratory distress, but it's not directly related to digoxin toxicity.
Choice D rationale:
Infrequent voiding is not a specific sign of digoxin toxicity. It could be related to various factors, such as fluid intake, renal function, or underlying medical conditions, but it's not a hallmark of digoxin toxicity.

Correct Answer is A
Explanation
Choice A rationale:
Stomatitis, inflammation of the oral mucosa, can make eating painful, leading to inadequate nutritional intake. The discomfort caused by stomatitis can discourage the patient from eating, potentially resulting in malnutrition. Ensuring adequate nutritional intake is crucial to support the patient's immune system and healing during antineoplastic therapy.
Choice B rationale:
Dental caries are not directly related to stomatitis. Stomatitis is inflammation of the oral mucosa, whereas dental caries involve decay of tooth structure due to bacterial action on food debris and sugars.
Choice C rationale:
Diarrhea is unrelated to stomatitis. Diarrhea involves frequent, loose, or watery stools, often caused by gastrointestinal infections, certain medications, or dietary intolerances.
Choice D rationale:
Gingival hyperplasia is an overgrowth of gum tissue and is not a likely result of stomatitis. It can be associated with some medications like anticonvulsants.
Correct Answer is B
Explanation
Choice A rationale:
Neck vein distention might be seen in conditions affecting venous return to the heart, such as heart failure, but it's not a specific symptom of closed head injury.
Choice B rationale:
Fixed, dilated pupils are a classic sign of increased intracranial pressure. The pressure can compress the cranial nerves, leading to changes in pupillary size and reactivity.
Choice C rationale:
Shortness of breath is more related to respiratory issues and might not be directly linked to a closed head injury.
Choice D rationale:
Glycosuria, the presence of glucose in the urine, is not a primary symptom of closed head injury. It could be related to diabetes or other metabolic conditions.
