Final answer:
The nurse should revise option 3, which is using arm restraints while asleep in the care plan for a toddler with a seizure disorder.
Step-by-step explanation:
The item in the care plan for a toddler with a seizure disorder that a nurse should revise is 3. Arm restraints while asleep. It is important to note that restraints should not be used in the care of a toddler with a seizure disorder because it may restrict movement and increase the risk of injury during a seizure.
Padded side rails (option 1), oxygen mask and bag system at bedside (option 2), and cardiorespiratory monitoring (option 4) are appropriate measures in the care plan for a toddler with a seizure disorder. Padded side rails help prevent injury if the toddler has a seizure and hits the side of the bed. An oxygen mask and bag system can be used to provide supplemental oxygen if the toddler experiences respiratory distress during or after a seizure. Cardiorespiratory monitoring allows healthcare providers to monitor the toddler's heart rate and breathing to identify any abnormalities during and after a seizure.
