Neurological Assessment NCLEX Questions Questions
Question 1 of 5
A 27-year-old woman is brought to the emergency department by her co-workers after falling to the ground, followed by full-body shaking and jerking lasting less than 30 seconds. The event occurred after she received the news of the death of her grandmother. Just before falling, she felt lightheaded and nauseous. Her co-workers state she fell suddenly, her eyes rolled back, she had some groaning, and it looked like she had a 'grand mal seizure' for 10-15 seconds. Shortly after the jerking stopped, she regained consciousness and got up from the ground within a minute or so. She was fully awake afterward. She had some mild urinary incontinence. On physical examination, the patient appears anxious. Heart auscultation reveals normal S1 and S2 without murmurs, rubs, or gallops. there is no evidence of a tongue bite. Which of the following is the best next step in management?
Correct Answer: A
Rationale: Brief shaking after emotional stress with prodrome (lightheadedness, nausea) and rapid recovery suggests syncope, possibly vasovagal or cardiac. A 12-lead ECG is critical to rule out arrhythmia (e.g., long QT). Seizures typically last longer and have postictal confusion.
Question 2 of 5
The tiny space between neurons or a neuron and its target muscle is the:
Correct Answer: D
Rationale: The synapse is the small gap between neurons or between a neuron and a target cell (e.g., muscle), where signal transmission occurs.
Question 3 of 5
The speed of impulse conduction along an axon may be increased by
Correct Answer: A
Rationale: The myelin sheath insulates axons, enabling saltatory conduction, which significantly speeds up impulse transmission by allowing it to jump between nodes of Ranvier.
Question 4 of 5
One neurotransmitter associated with sleep, mood, attention, and learning is
Correct Answer: D
Rationale: Serotonin regulates sleep, mood, attention, and learning, synthesized in the raphe nuclei and widely distributed in the brain.
Question 5 of 5
Which of the following results from stimulation by the parasympathetic nervous system?
Correct Answer: D
Rationale: The parasympathetic system promotes 'rest and digest,' stimulating salivation, unlike sympathetic effects like increased heart rate.
