Medical history includes hypertension, coronary artery disease, and osteoporosis. Home medications include hydrochlorothiazide, amlodipine, losartan, vitamin D supplement, and senna. LTC nursing staff report 4-day history of upper respiratory infection. Client had decreased oral intake of food and fluid with onset of illness. Chest x-ray confirms bacterial respiratory infection.

Answer & explanation
Correct:
This client has progressive hypernatremia with sodium levels rising to 155 mEq/L by 5/10, accompanied by worsening neurological deterioration — confusion progressing to near-unresponsiveness. Severe hypernatremia causes neuronal shrinkage and cerebral irritability, placing the client at significant risk for seizures. This is the most clinically urgent complication given the sodium level and altered mental status trajectory. Because seizure risk is elevated, the nurse should pad the side rails to protect the client from injury if a seizure occurs. This is the standard safety intervention for seizure precautions. Simply reorienting the client or administering glucose gel would not address seizure risk. Ensuring oxygen is available at the bedside is the correct third selection because oxygen delivery is a priority during and after a seizure, as seizure activity increases metabolic demand and can cause hypoxia. Orange juice would be appropriate for hypoglycemia, not hypernatremia or seizures. Cardiac monitoring, while useful in some electrolyte disturbances, is not the primary bedside priority for seizure management. The clinical reasoning connects the severely elevated sodium, the neurological changes, and the evidence-based nursing response: implement seizure precautions by padding side rails and having oxygen immediately accessible.
