Correct Answer is D

Explanation

A. A positive Romberg sign (difficulty maintaining balance with eyes closed) can indicate a neurological issue, but it is not directly associated with a migraine.

B. A subnormal temperature (low body temperature) is not typically associated with migraines and may indicate another issue, but it is not as concerning as other findings.

C. An ill college roommate might suggest a viral illness, but it is not a direct concern for the student’s migraine. Migraines are not contagious, and other signs of illness would be more concerning.

D. Positive Brudzinski sign, which involves involuntary flexion of the hips and knees when the neck is flexed, is indicative of meningeal irritation, a sign of meningitis. This is a medical emergency and much more concerning than the symptoms of a migraine. The student should be further assessed for signs of meningitis, which requires urgent treatment.

A. A sensory warning that a seizure is imminent B. A brief loss of consciousness accompanied by staring C. A continuous seizure state in which seizures occur in rapid succession D. A period of sleepiness following the seizure during which arousal is difficult

Correct Answer is A

Explanation

A. An aura is a sensory warning (such as a strange taste, smell, or visual disturbance) that often precedes a seizure, indicating that a seizure is imminent. It is a common experience for individuals with certain types of seizures, such as focal seizures.

B. A brief loss of consciousness accompanied by staring is indicative of absence seizures, not an aura.

C. A continuous seizure state in which seizures occur in rapid succession is known as status epilepticus, a medical emergency.

D. A period of sleepiness following the seizure is called the postictal state, but this is not related to an aura, which occurs before the seizure.
