NCLEX Neurology Practice Questions Questions
Question 1 of 5
Which of the following interventions should you perform for a patient admitted with an order for seizure precautions?
Correct Answer: A
Rationale: Seizure precautions aim to ensure safety and treatment readiness. Obtaining IV access allows for rapid administration of anticonvulsants if needed. Keeping lights on or raising the bed increases risk, and tongue blades are outdated and unsafe.
Question 2 of 5
A 9-year-old female patient is brought to the pediatrician because she says 'a heart is in my head.' She reports bilateral headaches of pulsating quality, nausea, and has vomited 4 times. Her headache began approximately 6 hours ago, and says that lights worsen her symptoms. Her eyes are red teary and she reports nasal congestion. She is in the 4th grade, and does exceptionally well in school; her mother notes she was a colicky baby and is prone to car sickness She has a cat a home that scratched her face earlier today. She is sitting on the exam table wearing sunglasses. She does not appear severely ill. Vitals signs are stable, and there are no focal neurological deficits. Which of the following is most likely the diagnosis?
Correct Answer: B
Rationale: Pulsating bilateral headache with nausea, photophobia, and vomiting in a child with a motion sickness history suggests migraine. Corneal abrasion causes unilateral pain, tension headache lacks nausea, and seizures involve altered consciousness.
Question 3 of 5
A 37-year-old African American woman presents to the emergency department with pain and vision loss in her right eye. These symptoms progressively worsened over the course of hours. She also reports muscle weakness and sensory changes in both upper extremities. This has never happened before. The patient has a history of ulcerative colitis treated with oral 5-aminosalicylate, and hypertension that is adequately controlled on hydrochlorothiazide. On physical exam, she has a visual acuity of 20/20 in the left eye and 20/200 on the right, a right relative afferent pupil defect, and symmetric motor and sensory deficits more pronounced in the upper extremity. An MRI of brain was normal. MRI spinal cord was obtained with findings shown to the right. Which of the following is most likely the diagnosis?
Correct Answer: D
Rationale: Unilateral optic neuritis (vision loss, RAPD) with spinal cord symptoms (weakness, sensory loss) and normal brain MRI suggest neuromyelitis optica spectrum disorder (NMOSD), often with longitudinally extensive transverse myelitis. MS typically shows brain lesions.
Question 4 of 5
Nerve impulses are picked up by a neuron's (nerve cell):
Correct Answer: A
Rationale: Dendrites are the branched extensions of a neuron that receive incoming nerve impulses from other neurons or sensory receptors.
Question 5 of 5
The functional unit of the nervous system is the
Correct Answer: B
Rationale: The neuron is the basic structural and functional unit of the nervous system, capable of receiving, processing, and transmitting signals.
