NCLEX Neurology Practice Questions with Answers

Mastering NCLEX neurology practice questions is essential for nursing students because the neurological system governs every vital function from respiratory drive to motor coordination. This guide provides a comprehensive review of neuro-assessment, stroke management, increased intracranial pressure (ICP), and degenerative disorders to ensure you are prepared for the Next-Gen NCLEX (NGN).

Concept Explanation

Neurological nursing focuses on the assessment, diagnosis, and management of disorders affecting the central and peripheral nervous systems, prioritizing the maintenance of airway, breathing, and cerebral perfusion. The core of neurological care involves monitoring for changes in the Glasgow Coma Scale (GCS), identifying signs of increased intracranial pressure, and reacting swiftly to acute events like ischemic strokes or seizures. When studying for the exam, it is vital to understand the difference between focal deficits and systemic neurological collapse. Many questions will test your ability to prioritize care using the ABCs (Airway, Breathing, Circulation) alongside neuro-specific checks like pupillary response and motor strength. For those focusing on pharmacological interventions, reviewing hard NCLEX CNS medication practice questions can provide deeper insight into how drugs like phenytoin or mannitol affect the brain.

Key concepts often tested include:

• Increased Intracranial Pressure (ICP): Recognizing Cushing’s Triad (bradycardia, hypertension with widening pulse pressure, and irregular respirations) is a high-priority skill.
• Stroke (CVA): Differentiating between ischemic and hemorrhagic strokes and knowing the window for tPA (tissue plasminogen activator) administration.
• Spinal Cord Injuries: Understanding autonomic dysreflexia as a medical emergency occurring in injuries at or above T6.
• Seizure Safety: Prioritizing patient safety, airway patency, and post-ictal monitoring.

Solved Examples

Review these worked examples to understand the clinical reasoning required for NCLEX neurology questions.

1. Example 1: Increased Intracranial Pressure
   Question: A patient with a head injury has a blood pressure of 160/60 mmHg, a heart rate of 52 bpm, and irregular breathing. What is the nurse's priority action?
   1. Recognize these symptoms as Cushing’s Triad, indicating late-stage increased ICP.
   2. Elevate the head of the bed to 30 degrees to promote venous drainage.
   3. Notify the healthcare provider immediately as this indicates impending brain herniation.
   4. Ensure the neck is in a neutral, midline position to prevent jugular obstruction.
2. Example 2: Autonomic Dysreflexia
   Question: A client with a T4 spinal cord injury reports a severe, throbbing headache and has a flushed face. What should the nurse do first?
   1. Assess the patient's blood pressure (it will likely be severely elevated).
   2. Sit the patient upright (High-Fowler's) to help lower blood pressure via orthostatic changes.
   3. Check for bladder distension or fecal impaction, as these are common triggers.
   4. This is the classic presentation of autonomic dysreflexia, a life-threatening emergency.
3. Example 3: Myasthenia Gravis
   Question: A patient with Myasthenia Gravis is scheduled for a Tensilon (edrophonium) test. What medication must be at the bedside?
   1. Tensilon can cause a cholinergic crisis, leading to severe bradycardia or bronchospasm.
   2. Atropine is the antidote for cholinergic toxicity.
   3. The nurse must ensure Atropine is immediately available before the procedure begins.

   C. Restrict fluid intake for the first 24 hours.
   D. Place the client in a High-Fowler’s position.
2. A client with a history of seizures is prescribed phenytoin. Which sidet effect should the nurse instruct the client to report to the healthcare provider immediately?
   A. Gingival hyperplasia
   B. Pinkish-red discoloration of urine
   C. A blistering skin rash
   D. Increased hair growth (hirsutism)

   A. Negative Kernig’s sign
   B. Flaccid paralysis
   C. Nuchal rigidity
   D. Hypotension and bradycardia

4. A client is admitted with a suspected stroke. The nurse notes the client can understand speech but struggles to form words or speak fluently. This is documented as:
   A. Receptive aphasia
   B. Expressive aphasia
   C. Global aphasia
   D. Dysphagia
5. Which of the following is the priority nursing diagnosis for a client in the tonic-clonic phase of a seizure?
   A. Impaired physical mobility
   B. Risk for injury
   C. Risk for ineffective airway clearance
   D. Deficient knowledge regarding seizure triggers
6. A client with Parkinson’s Disease is taking carbidopa-levodopa. The nurse knows the medication is effective when the client demonstrates:
   A. Increased heart rate and blood pressure
   B. Decreased tremors and improved gait
   C. Reduced episodes of visual hallucinations
   D. Increased muscle rigidity
7. A nurse is assessing a client using the Glasgow Coma Scale (GCS). The client opens eyes to pain, uses inappropriate words, and withdraws from pain. What is the GCS score?
   A. 7
   B. 9
   C. 11
   D. 13
8. The nurse is caring for a client with a cerebral aneurysm. Which intervention should be included in "aneurysm precautions"?
   A. Encourage the client to cough and deep breathe every 2 hours.
   B. Keep the room well-lit and stimulate the client frequently.
   C. Maintain a quiet environment and limit visitors.
   D. Place the client in a Trendelenburg position.

Answers & Explanations

1. Answer: B. Maintaining a flat supine position helps prevent the leakage of cerebrospinal fluid (CSF) from the puncture site, which is the primary cause of post-lumbar puncture headaches. For more on clinical procedures, see our easy NCLEX dosage calculation practice questions for foundational nursing math.
2. Answer: C. A blistering skin rash can indicate Stevens-Johnson Syndrome, a rare but life-threatening adverse reaction to phenytoin. Gingival hyperplasia and pink urine are known side effects but are not as immediately dangerous. You can practice identifying these risks in our hard NCLEX adverse effect practice questions.
3. Answer: C. Nuchal rigidity (neck stiffness) is a hallmark sign of meningeal irritation. Kernig’s and Brudzinski’s signs would be positive, not negative.
4. Answer: B. Expressive aphasia (Broca's aphasia) occurs when the patient understands but cannot produce speech. Receptive aphasia (Wernicke's) involves an inability to understand language.
5. Answer: C. While "Risk for injury" is important, "Risk for ineffective airway clearance" is the priority during the active seizure phase to ensure the patient does not aspirate or stop breathing.
6. Answer: B. Carbidopa-levodopa aims to increase dopamine levels in the brain to reduce the motor symptoms of Parkinson's, such as bradykinesia and tremors.
7. Answer: B. Eyes to pain = 2; Inappropriate words = 3; Withdraws from pain = 4. Total = 9. Scores of 8 or less typically indicate a coma.
8. Answer: C. Aneurysm precautions aim to prevent rupture by minimizing physical and emotional stress. This includes a dark, quiet room and avoiding activities that increase ICP, such as coughing.

Quick Quiz

Frequently Asked Questions

What is the most sensitive indicator of neurological status?

The Level of Consciousness (LOC) is the most sensitive and earliest indicator of changes in neurological status. Even subtle changes in orientation or alertness can signal increasing intracranial pressure or decreasing cerebral perfusion.

How do I calculate a Glasgow Coma Scale score?

The GCS is calculated by adding scores from three categories: Eye Opening (1-4), Verbal Response (1-5), and Motor Response (1-6). The total score ranges from 3 to 15, where a lower score indicates more severe neurological impairment.

What is the difference between decorticate and decerebrate posturing?

Decorticate posturing involves internal rotation and adduction of the arms with flexion of the elbows (moving toward the "cord"), indicating damage to the cerebral hemispheres. Decerebrate posturing involves rigid extension of the arms and legs, indicating more severe damage to the brainstem.

What are the priority assessments for a patient after a stroke?

Priority assessments include maintaining a patent airway, monitoring neurological checks (GCS and pupils), and assessing swallowing ability (dysphagia) before allowing any oral intake. These steps prevent complications like aspiration pneumonia and secondary brain injury.

When is tPA contraindicated in stroke patients?

tPA is contraindicated if the patient has a hemorrhagic stroke, recent major surgery, active internal bleeding, or a history of intracranial hemorrhage. It must typically be administered within a 3 to 4.5-hour window from the "last known normal" time of ischemic stroke onset.
