An individual receiving phenytoin (Dilantin) for a seizure would need monitoring of

Urine output
Respiratory rate
Heart rate
Blood concentration

The correct answer is: Blood concentration

When an individual is receiving phenytoin (Dilantin) for seizures, it is crucial to monitor their blood concentration levels. Monitoring blood concentration levels of phenytoin is essential because this medication has a narrow therapeutic range. Maintaining the drug within this range is critical for controlling seizures and preventing adverse effects. Monitoring blood concentration levels helps healthcare providers adjust the dosage as needed to ensure the medication is effective and safe for the individual. Monitoring urine output, respiratory rate, and heart rate are also important aspects of patient care but are not specific to the monitoring requirements for phenytoin (Dilantin) therapy. These parameters may be monitored for overall patient health assessment and management but are not directly associated with phenytoin therapy monitoring.
