Correct Answer is A
Explanation
A. Move the child into a side-lying position: This is the priority action to maintain an open airway, promote drainage of vomit, and reduce the risk of aspiration.
B. Remove the child's eyeglasses: While helpful to prevent injury, it is not the priority action during an active seizure.
C. Time the seizure: Timing is important to assess the duration and severity of the seizure, but it does not address immediate safety concerns like aspiration.
D. Place a pillow under the child's head: While this may prevent head injury, repositioning to a side-lying position to prevent aspiration is more critical.
Correct Answer is B
Explanation
A. Apply oxygen by nasal cannula: Applying oxygen can be beneficial but is not the immediate priority during an active seizure. Protecting the airway comes first.
B. Turn the client to a lateral position: This action prevents aspiration by keeping the airway clear if the client vomits or has excessive secretions.
C. Administer an anticonvulsant medication: Medications may be necessary later, but immediate safety and airway protection take precedence.
D. Check the client’s oxygen saturation: Monitoring oxygen saturation is important but should follow positioning to ensure airway protection.
