EXAM COVERAGE - 1. Advanced Hemodynamic and Intracranial Pressure
Monitoring - 2. Acute Stroke and Vascular Neurosurgery - 3. Status
Epilepticus and Continuous EEG Monitoring - 4. Traumatic Brain and
Spinal Cord Injury Management - 5. Neuromuscular Respiratory Failure
and Autoimmune Crises - 6. Neuropharmacology, Sedation, and
Multimodality Monitoring
1. A 58-year-old male with a severe traumatic brain injury has an external ventricular drain (EVD) in place. His
intracranial pressure (ICP) spikes to 28 mmHg, and his mean arterial pressure (MAP) is 88 mmHg. What is
his current cerebral perfusion pressure (CPP), and how should it be clinically evaluated?
A. CPP is 60 mmHg; this is within the optimal target range for severe TBI management.
B. CPP is 60 mmHg; this falls below the standard target threshold of 60-70 mmHg and requires
immediate intervention.
C. CPP is 116 mmHg; this indicates significant risk for hyperperfusion and cerebral edema.
D. CPP is 50 mmHg; this is acceptable as long as jugular venous saturation remains above 55%.
CORRECT ANSWER : B
Rationale: Cerebral perfusion pressure (CPP) is calculated as MAP minus ICP (88 - 28 = 60 mmHg).
Current guidelines recommend maintaining CPP between 60 to 70 mmHg in severe TBI to prevent both
ischemia from hypoperfusion and secondary injury from hyperemia. A CPP of 60 mmHg sits at the absolute
minimum threshold, and given the acute spike in ICP, targeted therapies to reduce ICP or elevate MAP are
urgently required.
2. A patient admitted with an aneurysmal subarachnoid hemorrhage (SAH) on day 6 post-op suddenly
develops right-sided hemiparesis and a decline in GCS score from 14 to 11. Transcranial Doppler (TCD)
velocities in the left middle cerebral artery (MCA) register at 210 cm/s. Which diagnostic and therapeutic
intervention is indicated first?
A. Immediate administration of intravenous recombinant tissue plasminogen activator (rt-PA).
B. Emergency surgical clipping of a recurrent aneurysm rupture.
, C. Initiation of induced hypertension and diagnostic cerebral angiography with possible
angioplasty or intra-arterial vasodilator therapy.
D. Immediate administration of high-dose barbiturates to suppress cerebral metabolic rate.
CORRECT ANSWER : C
Rationale: The patient is exhibiting classic signs of symptomatic cerebral vasospasm, which typically peaks
between days 3 and 14 following an aneurysmal SAH. High TCD velocities (>200 cm/s in the MCA)
combined with a focal neurologic deficit mandate intervention for vasospasm, usually starting with induced
hypertension ("triple-H" therapy component) and proceeding to cerebral angiography for mechanical or
pharmacological angioplasty if medical management fails.
3. A patient in status epilepticus has failed initial treatment with weight-based intravenous lorazepam and
levetiracetam. Continuous video EEG shows persistent electrographic seizure activity. Which medication
represents the most appropriate next step in pharmacological management?
A. Phenytoin 15 mg/kg IV infused at 50 mg/min.
B. Propofol infusion with continuous EEG monitoring and hemodynamic support.
C. Valproate sodium 20 mg/kg IV push over 2 minutes.
D. Oral administration of carbamazepine via nasogastric tube.
CORRECT ANSWER : B
Rationale: Refractory status epilepticus (RSE) defined as failure of a benzodiazepine and a second-line
antiepileptic drug requires general anesthesia with continuous EEG monitoring. Propofol, midazolam, or
burst-suppression doses of pentobarbital are standard continuous infusion agents used in the ICU setting.
Phenytoin and valproate are second-line agents, while oral agents are inappropriate for active, ongoing
refractory status.
4. A nurse is managing a patient with acute ischemic stroke who received IV alteplase 2 hours ago. The
patient suddenly develops worsening headache, acute hypertension (BP 192/105 mmHg), and a decline in
level of consciousness. What is the priority nursing action?
A. Administer sublingual nifedipine immediately to lower blood pressure.
B. Stop the alteplase infusion immediately and prepare for emergency non-contrast head CT.
C. Place the head of the bed flat to maximize cerebral blood flow.
D. Draw a stat CBC and type-and-crossmatch while continuing current management.
CORRECT ANSWER : B
, Rationale: Acute neurological deterioration and severe hypertension following administration of thrombolytic
therapy strongly suggest symptomatic intracranial hemorrhage (sICH), a fatal complication. The alteplase
infusion must be stopped immediately, and an emergency non-contrast CT scan of the head is required to
confirm the diagnosis. Blood pressure should be managed per protocol, avoiding sudden drops that worsen
ischemia.
5. A patient with a C5 spinal cord injury experiences a sudden onset of throbbing headache, profound
hypertension (BP 210/110 mmHg), bradycardia (HR 48 bpm), and flushing above the level of the injury.
What is the primary nursing intervention?
A. Administer intravenous atropine to treat the bradycardia.
B. Sit the patient upright immediately and scan for noxious stimuli such as a distended bladder or
fecal impaction.
C. Lay the patient flat and administer sublingual nitroglycerin.
D. Perform immediate endotracheal intubation to secure the airway.
CORRECT ANSWER : B
Rationale: This clinical presentation is classic for autonomic dysreflexia, a medical emergency triggered by
noxious stimuli below the level of spinal injury (most commonly bladder distension or bowel impaction).
Raising the head of the bed immediately lowers blood pressure via orthostatic pooling, and the clinician
must rapidly identify and remove the triggering stimulus.
6. Which laboratory and cerebrospinal fluid (CSF) findings are most characteristic of Guillain-Barré Syndrome
(GBS)?
A. CSF pleocytosis with low protein and normal glucose levels.
B. CSF albuminocytologic dissociation (severely elevated protein with normal cell count).
C. CSF with marked lymphocytic predominance and depressed glucose levels.
D. CSF positive for oligoclonal bands with normal protein concentrations.
CORRECT ANSWER : B
Rationale: Guillain-Barré Syndrome classically presents with albuminocytologic dissociation in CSF
analysis, characterized by a significantly elevated protein level accompanied by a normal cell count
(absence of pleocytosis). This differentiates GBS from infectious etiologies such as meningitis or
encephalitis, which typically present with elevated white blood cells.
7. A patient with Myasthenia Gravis is admitted to the neurological ICU in acute myasthenic crisis. Which
intervention takes immediate precedence?
, A. Administration of high-dose oral pyridostigmine.
B. Assessment of forced vital capacity (FVC) and negative inspiratory force (NIF) to evaluate for
impending respiratory failure.
C. Immediate administration of broad-spectrum intravenous antibiotics.
D. Scheduling the patient for emergency thymectomy.
CORRECT ANSWER : B
Rationale: Myasthenic crisis involves severe respiratory muscle weakness leading to hypoventilation. Serial
pulmonary function testing—specifically monitoring forced vital capacity (FVC) and negative inspiratory
force (NIF)—is critical to detect declining respiratory mechanics before overt arrest occurs, allowing for
timely elective intubation.
8. When calculating cerebral perfusion pressure (CPP) in an ICP-monitored patient with an arterial line, which
transducers must be properly leveled and zeroed to ensure accuracy?
A. The phlebostatic axis for the arterial line and the external auditory meatus (foramen of Monro) for
the ICP transducer.
B. The left atrium for both the arterial line and the external ventricular drain.
C. The mid-axillary line for the ICP transducer and the suprasternal notch for the arterial line.
D. The tragus of the ear for both transducers regardless of patient positioning.
CORRECT ANSWER : A
Rationale: Accurate hemodynamic and intracranial calculations depend on precise transducer calibration.
The arterial line transducer must be zeroed at the level of the right atrium (phlebostatic axis), while the ICP
transducer/EVD system must be zeroed at the level of the foramen of Monro (external auditory meatus) to
reflect true hydrostatic pressure at the brain base.
9. A patient with a severe subarachnoid hemorrhage is placed on prophylactic nimodipine. What is the
primary pharmacological purpose of this medication?
A. To reduce systemic blood pressure and prevent rebleeding of the aneurysm.
B. To selectively prevent and treat cerebral vasospasm and subsequent delayed cerebral ischemia.
C. To reduce intracranial pressure by osmotic diuresis across the blood-brain barrier.
D. To suppress seizure activity originating from cortical irritation.
