A nurse is caring for a group of toddlers receiving digoxin therapy. For which of the following toddlers should the nurse revise the plan of care?

The correct answer is Choice D.Choice A rationaleA digoxin level of 1.2 ng/mL is within the therapeutic range (0.8 to 2 ng/mL) for toddlers receiving digoxin therapy. This level does not require a revision of the plan of care.Choice B rationaleAn apical pulse of 100/min is within the normal range for toddlers. Digoxin therapy requires monitoring of the heart rate, but this pulse rate does not necessitate a change in the plan of care.Choice C rationaleA potassium level of 4.0 mEq/L is within the normal range (3.4 to 4.7 mEq/L) for toddlers. This electrolyte level does not require a revision of the plan of care.Choice D rationaleVomiting is a potential sign of digoxin toxicity. A toddler who has vomited 2 times in the last hour may be experiencing digoxin toxicity, and the plan of care should be revised to address this issue. .
