Question 1: A 68-year-old patient presents with sudden onset of right-sided facial
droop, arm weakness, and slurred speech that began 90 minutes ago. Which
intervention should the nurse prioritize?
A. Administer aspirin 325 mg orally
B. Prepare the patient for emergent CT scan of the head
C. Obtain a 12-lead electrocardiogram
D. Initiate oxygen therapy at 2 L/min via nasal cannula
CORRECT ANSWER: B. Prepare the patient for emergent CT scan of the head
Rationale: In acute stroke presentation, rapid neuroimaging with a non-contrast CT
scan is the priority to differentiate between ischemic and hemorrhagic stroke before
initiating thrombolytic therapy. Time is critical, and the CT scan must be completed
within 25 minutes of arrival to determine eligibility for tissue plasminogen activator
(tPA). While oxygen and cardiac monitoring are important, confirming stroke type takes
precedence to guide definitive treatment.
Question 2: Which clinical finding in a patient with increased intracranial pressure
(ICP) represents Cushing's triad?
A. Tachycardia, hypotension, and irregular respirations
B. Bradycardia, hypertension with widened pulse pressure, and irregular respirations
C. Hypertension, tachypnea, and hyperthermia
D. Bradypnea, hypotension, and pupillary constriction
CORRECT ANSWER: B. Bradycardia, hypertension with widened pulse pressure,
and irregular respirations
Rationale: Cushing's triad is a late and ominous sign of significantly elevated ICP and
brainstem herniation. It consists of bradycardia (due to vagal stimulation), systolic
hypertension with widened pulse pressure (a compensatory mechanism to maintain
cerebral perfusion), and irregular or abnormal respiratory patterns. Recognition of this
triad requires immediate intervention to reduce ICP and prevent irreversible
neurological damage.
Question 3: A patient with a history of epilepsy is admitted following a generalized
tonic-clonic seizure. Which nursing action is most appropriate during the postictal
phase?
,A. Restrain the patient to prevent injury
B. Place the patient in a side-lying position
C. Administer intravenous lorazepam immediately
D. Offer oral fluids to prevent dehydration
CORRECT ANSWER: B. Place the patient in a side-lying position
Rationale: During the postictal phase, the patient is at risk for aspiration due to
decreased level of consciousness and possible residual oral secretions. Positioning the
patient laterally promotes airway patency and drainage of secretions. Restraints are
contraindicated as they can cause injury. Anticonvulsants are administered during
active seizures, not postictally, and oral intake should be withheld until the patient is
fully alert to prevent aspiration.
Question 4: Which assessment finding is most indicative of a patient experiencing
a transient ischemic attack (TIA) rather than a completed stroke?
A. Persistent left hemiparesis lasting 48 hours
B. Resolution of aphasia within 30 minutes of symptom onset
C. Visual field deficit confirmed on MRI
D. Elevated serum glucose level
CORRECT ANSWER: B. Resolution of aphasia within 30 minutes of symptom onset
Rationale: A transient ischemic attack (TIA) is defined by temporary neurological
dysfunction caused by focal brain, spinal cord, or retinal ischemia without acute
infarction. Symptoms typically resolve within minutes to less than 1 hour, and always
within 24 hours. Persistent deficits beyond this timeframe suggest completed stroke.
MRI may show infarction even after symptom resolution, but the clinical hallmark of TIA
is complete symptom resolution.
Question 5: A patient diagnosed with Parkinson's disease is prescribed levodopa-
carbidopa. Which patient statement indicates understanding of medication
teaching?
A. "I should take this medication with a high-protein meal to enhance absorption."
B. "I may notice my urine turning dark orange, which is harmless."
C. "I will rise slowly from sitting to prevent dizziness."
D. "I can stop taking this medication if my tremors improve."
CORRECT ANSWER: C. "I will rise slowly from sitting to prevent dizziness."
Rationale: Levodopa-carbidopa can cause orthostatic hypotension, increasing fall risk.
Patients should be taught to change positions slowly. High-protein meals interfere with
levodopa absorption and should be timed separately. Dark urine is not a typical side
effect; however, sweat and urine may darken slightly. Abrupt discontinuation can lead to
a life-threatening withdrawal syndrome resembling neuroleptic malignant syndrome
and must be avoided.
,Question 6: Which cranial nerve is primarily assessed when testing the gag reflex in
a patient with suspected brainstem injury?
A. Cranial Nerve V (Trigeminal)
B. Cranial Nerve VII (Facial)
C. Cranial Nerve IX (Glossopharyngeal)
D. Cranial Nerve XII (Hypoglossal)
CORRECT ANSWER: C. Cranial Nerve IX (Glossopharyngeal)
Rationale: The gag reflex involves afferent fibers of Cranial Nerve IX (glossopharyngeal)
and efferent fibers of Cranial Nerve X (vagus). Testing this reflex assesses brainstem
integrity, particularly the medulla. Absence of the gag reflex may indicate brainstem
dysfunction and increases aspiration risk. CN V controls facial sensation and
mastication; CN VII controls facial expression; CN XII controls tongue movement.
Question 7: A patient with multiple sclerosis experiences sudden worsening of
neurological symptoms following a urinary tract infection. This phenomenon is
best described as:
A. Disease progression
B. Pseudorelapse
C. Secondary progression
D. Clinically isolated syndrome
CORRECT ANSWER: B. Pseudorelapse
Rationale: A pseudorelapse (or pseudoexacerbation) in multiple sclerosis refers to the
temporary worsening of existing neurological symptoms due to an external trigger such
as infection, fever, or stress, without new demyelinating activity. Symptoms typically
resolve once the trigger is treated. This differs from a true relapse, which involves new or
worsening symptoms lasting >24 hours due to acute inflammation and demyelination.
Question 8: Which intervention is contraindicated in a patient with suspected
increased intracranial pressure?
A. Elevating the head of the bed to 30 degrees
B. Administering stool softeners to prevent straining
C. Performing routine suctioning every 2 hours
D. Maintaining normothermia
CORRECT ANSWER: C. Performing routine suctioning every 2 hours
Rationale: Suctioning can significantly increase intrathoracic and intra-abdominal
pressure, which impedes venous return from the brain and elevates ICP. Suctioning
should be performed only when clinically indicated, using pre-oxygenation and limiting
duration to <10 seconds. Head elevation, preventing Valsalva maneuvers, and
temperature control are evidence-based strategies to manage ICP.
, Question 9: A patient with myasthenia gravis presents with ptosis, diplopia, and
difficulty swallowing. Which medication should the nurse anticipate administering
to rapidly improve symptoms?
A. Pyridostigmine
B. Prednisone
C. Azathioprine
D. Intravenous immunoglobulin
CORRECT ANSWER: A. Pyridostigmine
Rationale: Pyridostigmine is an acetylcholinesterase inhibitor that increases
acetylcholine availability at the neuromuscular junction, providing rapid symptomatic
relief in myasthenia gravis. It is first-line for mild to moderate symptoms. Prednisone
and azathioprine are immunosuppressants used for long-term management. IVIG or
plasmapheresis is reserved for myasthenic crisis or severe exacerbations.
Question 10: Which finding on lumbar puncture is most consistent with bacterial
meningitis?
A. Clear cerebrospinal fluid with normal glucose
B. Cloudy cerebrospinal fluid with elevated protein and low glucose
C. Xanthochromic fluid with normal white blood cell count
D. Elevated opening pressure with lymphocytic predominance
CORRECT ANSWER: B. Cloudy cerebrospinal fluid with elevated protein and low
glucose
Rationale: Bacterial meningitis typically presents with cloudy CSF due to high
neutrophil count, elevated protein from blood-brain barrier disruption, and low glucose
(hypoglycorrhachia) due to bacterial consumption. Viral meningitis usually shows
lymphocytic predominance with normal glucose. Xanthochromia suggests
subarachnoid hemorrhage. Elevated opening pressure can occur in both bacterial and
viral meningitis but is nonspecific.
Question 11: A patient with Guillain-Barré syndrome is being monitored for
respiratory compromise. Which assessment parameter is the earliest indicator of
impending respiratory failure?
A. Decreased oxygen saturation
B. Vital capacity less than 20 mL/kg
C. Inability to lift the head off the pillow
D. Paradoxical abdominal breathing
CORRECT ANSWER: B. Vital capacity less than 20 mL/kg
Rationale: Vital capacity (VC) is the most sensitive and earliest objective measure of
respiratory muscle weakness in Guillain-Barré syndrome. A VC <20 mL/kg indicates
significant diaphragmatic involvement and high risk for respiratory failure, often
