Correct Answer is A
Explanation
A. Aura: An aura is a subjective sensation experienced before a seizure, such as a strange smell, taste, or visual change. It can provide clues about the seizure's origin in the brain, often linked to the temporal lobe.
B. Blood Pressure 90/60: Blood pressure is an objective, measurable sign, not subjective data reported by the child.
C. Oxygenation on room air 97%: Oxygenation levels are objective and do not provide information about seizure origin.
D. Temperature 38 degrees Celsius: Temperature is objective and does not help localize the seizure's origin in the brain.
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.
