Question 1 of 5
A 31-year-old woman is brought to the emergency department by her partner due to a convulsive episode after an argument. Her partner described the convulsive episode as being abrupt in onset, with asynchronous limb movements, and pelvic thrusting. The patient's eyes were closed throughout the episode and was unresponsive. The event lasted approximately 10-15 minutes, and would consist of bursts of movement followed by pauses, occurring in a stopping-and-starting fashion. The convulsive episode ended abruptly, with complete recovery. The patient said that during the event, she could sometimes hear what people were saying, but was unable to respond. She says she has seizures 2-3 times per week. Physical examination is unremarkable. On videoelectroencephalogram (video-EEG), one of her typical events is recorded, without any abnormality on scalp EEG. What is the most appropriate treatment for this disorder?
Correct Answer: C
Rationale: Prolonged, asynchronous movements with awareness and normal EEG suggest psychogenic non-epileptic seizures (PNES), often stress-related. Cognitive-behavioral therapy addresses underlying psychological triggers.
Question 2 of 5
The brain is protected by:
Correct Answer: D
Rationale: The brain is safeguarded by the meninges (membranes), cerebrospinal fluid (cushion), and the skull (bony structure), all working together.
Question 3 of 5
Once the threshold potential is reached,
Correct Answer: C
Rationale: Reaching the threshold triggers rapid Na⁺ channel opening, making an action potential unavoidable due to the all-or-none principle.
Question 4 of 5
The uniformity in the way nerve cells function within the animal kingdom
Correct Answer: B
Rationale: Conserved neuron function across animals suggests it evolved early, enabling complex nervous systems to build upon this foundation.
Question 5 of 5
In all vertebrates, the brain consists of the
Correct Answer: C
Rationale: Vertebrate brains are divided embryonically into forebrain, midbrain, and hindbrain, encompassing all regions like the cerebrum and cerebellum.
