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 D
Explanation
A. Decreased pressure and cloudy cerebrospinal fluid with a high protein level. Meningitis usually causes increased intracranial pressure, not decreased.
B. Clear cerebrospinal fluid with a high protein and low glucose. Clear CSF is typically seen in viral meningitis, but bacterial meningitis more often causes cloudy CSF.
C. Cloudy cerebrospinal fluid with a low protein and low glucose. While glucose is low in bacterial meningitis, protein is typically elevated due to the infection.
D. Cloudy cerebrospinal fluid with a high protein and low glucose levels. This finding is consistent with bacterial meningitis, where the CSF is cloudy, protein is elevated due to inflammation, and glucose is low because bacteria consume glucose.
