The elderly patient is taking phenobarbital (Luminal) for seizure control. What is most important for the nurse to assess in the patient?
1. Fluid intake
2. Electrolyte balance
3. Respiratory function
4. Nutritional status
Correct Answer: 3
Rationale: Elderly patients are at risk for cumulative effects of barbiturates due to diminished hepatic and renal function. Central nervous system (CNS) depression can lead to suppression of respiratory function. Nutritional status is important with elderly patients, but is not the primary concern. Fluid intake is often decreased in elderly patients, but is not a side effect of barbiturates. Barbiturates do not affect electrolyte balance.
