During a seizure, what is the primary intervention?
- A. Protect the patient from injury
- B. Insert an airway
- C. Elevate the head of the bed
- D. Withdraw all pain medications
Correct Answer: A
Rationale: The primary intervention during a seizure is to protect the patient from injury. This includes moving nearby objects that may harm the patient, cushioning the head, and ensuring a safe environment until the seizure subsides. Inserting an airway is not typically done during a seizure unless the patient's airway is compromised, while elevating the head of the bed is not the priority during an active seizure. Withdrawing all pain medications is not necessary unless there are specific contraindications related to the seizure event.
