Correct answer: It worsens infarct size by promoting lactic acidosis and cerebral edema

Hyperglycemia promotes anaerobic metabolism, lactic acidosis, and cerebral edema, all of which expand the ischemic injury.

Question 64: Which laboratory value is most important to check BEFORE initiating IV alteplase in an acute ischemic stroke patient?

Troponin I
Blood glucose level
Complete metabolic panel (CMP)
Prothrombin time (PT) and INR (Correct answer)

Correct answer: Prothrombin time (PT) and INR

Elevated INR (>1.7) is a contraindication to alteplase; checking PT/INR is critical to rule out coagulopathy before thrombolysis.

Question 65: What is the role of the blood-brain barrier in stroke?

It prevents the passage of harmful substances but limits drug access in stroke (Correct answer)
It allows all substances to pass into the brain
It increases the risk of stroke
It has no role in stroke management

Correct answer: It prevents the passage of harmful substances but limits drug access in stroke

The blood-brain barrier (BBB) is a highly selective semipermeable membrane that protects the brain from circulating toxins and pathogens while allowing essential nutrients to pass. In stroke, while it helps protect against further damage from systemic substances, its integrity can be compromised. It also poses a challenge by limiting the delivery of therapeutic drugs to the affected brain tissue, making treatment more complex.

Question 66: Why is blood pressure management crucial in acute stroke care?

To prevent further bleeding and brain injury (Correct answer)
To reduce stress on the heart
To reduce pain from the stroke
To increase the blood flow to the kidneys

Correct answer: To prevent further bleeding and brain injury

Blood pressure management is critical in acute stroke care, though the specific targets vary depending on stroke type. In hemorrhagic stroke, aggressive blood pressure control is essential to prevent further bleeding. In ischemic stroke, blood pressure is carefully managed to ensure adequate cerebral perfusion while avoiding excessively high pressures that could lead to hemorrhagic transformation or edema.

Question 67: A patient with acute ischemic stroke presents within 3 hours of symptom onset. Which medication is the first-line thrombolytic therapy?

Streptokinase
Alteplase (tPA) (Correct answer)
Tenecteplase
Reteplase

Correct answer: Alteplase (tPA)

Alteplase (IV tPA) is the FDA-approved first-line thrombolytic for acute ischemic stroke within the 3–4.5 hour window.

Question 68: Why is monitoring of vital signs critical in hyperacute care?

To determine when rehabilitation should begin
To prevent patient discomfort
To prepare the patient for discharge
To monitor for complications and stabilize the patient (Correct answer)

Correct answer: To monitor for complications and stabilize the patient

In hyperacute stroke care, frequent monitoring of vital signs is crucial for detecting rapid changes in a patient's condition. It allows healthcare providers to identify potential complications like increased intracranial pressure, blood pressure fluctuations, or respiratory distress early. Prompt detection enables timely interventions to stabilize the patient and prevent further neurological damage.

Question 69: Which risk management approach is MOST effective for SCRN professionals when evaluating potential workplace hazards?

Relying solely on historical accident data
Reactive analysis after incidents occur
Proactive hazard identification and assessment (Correct answer)
Delegating all safety decisions to management

Correct answer: Proactive hazard identification and assessment

Question 70: A patient with acute ischemic stroke has a serum sodium of 126 mEq/L on day 3. The most likely cause in the stroke population is:

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) (Correct answer)
Diabetes insipidus
Medication-induced diuresis
Hyperaldosteronism

Correct answer: Syndrome of inappropriate antidiuretic hormone secretion (SIADH)

SIADH is the most common cause of hyponatremia following stroke due to inappropriate ADH release from hypothalamic disruption.

Question 71: A patient with subarachnoid hemorrhage (SAH) from a ruptured aneurysm is at high risk for which serious delayed complication between days 4–14?

Cerebral vasospasm causing delayed ischemic neurological deficit (DIND) (Correct answer)
Hyperthyroidism
Pulmonary embolism
Hyponatremia from SIADH only

Correct answer: Cerebral vasospasm causing delayed ischemic neurological deficit (DIND)

Cerebral vasospasm peaks between days 4 and 14 after SAH and can cause delayed ischemic injury; nimodipine is given prophylactically to reduce this risk.

Question 72: A patient with hemorrhagic stroke is on a nicardipine infusion. The target systolic blood pressure is less than 140 mmHg per protocol. What is the primary rationale?

To reduce cerebral metabolic rate
To increase cerebral perfusion pressure
To prevent vasospasm
To limit hematoma expansion and improve outcomes (Correct answer)

Correct answer: To limit hematoma expansion and improve outcomes

Aggressive blood pressure lowering in intracerebral hemorrhage reduces ongoing hematoma expansion, which is a key driver of early neurological deterioration.

Question 75: What role does the carotid artery play in stroke risk?

It supplies blood to the lungs
It supplies blood to the brain, and blockage increases stroke risk (Correct answer)
It carries oxygen to the heart
It supplies blood to the kidneys

Correct answer: It supplies blood to the brain, and blockage increases stroke risk

The carotid arteries are major blood vessels located on each side of the neck that supply a significant portion of the blood to the brain. Atherosclerosis, or the buildup of plaque in these arteries, can narrow them (carotid artery stenosis) or lead to the formation of blood clots. This severely increases the risk of an ischemic stroke by impeding blood flow to the brain.

Question 76: Which neurological scale is used at the bedside to quantify stroke severity and guide acute treatment decisions?

Glasgow Coma Scale (GCS)
Hunt and Hess Scale
NIH Stroke Scale (NIHSS) (Correct answer)
Modified Rankin Scale (mRS)

Correct answer: NIH Stroke Scale (NIHSS)

The NIHSS provides a standardized, reproducible measure of acute stroke deficits and is used to determine tPA eligibility and monitor response to treatment.

Question 77: A stroke patient is being discharged on apixaban for newly diagnosed atrial fibrillation. The SCRN's education should emphasize which critical point?

Take apixaban only when symptomatic palpitations occur
Grapefruit juice enhances apixaban's effectiveness
Apixaban requires routine INR monitoring every week
Never miss a dose, avoid NSAIDs, and report unusual bleeding immediately (Correct answer)

Correct answer: Never miss a dose, avoid NSAIDs, and report unusual bleeding immediately

Consistent dosing adherence, avoidance of NSAIDs that increase bleeding risk, and prompt reporting of bleeding signs are essential for safe DOAC therapy.

Question 78: What documentation is MOST critical to maintain for safety compliance in the Stroke Certified Registered Nurse field?

Annual revenue reports
Incident reports, training records, and inspection logs (Correct answer)

Correct answer: Maintaining organized, dated, and signed records of all activities, training, and incidents

Organized, dated, and signed records demonstrate systematic compliance with regulatory requirements. Proper documentation serves as evidence during audits, protects against liability, and shows a pattern of consistent adherence to standards.

Question 80: What is a key consideration in post-acute stroke care for elderly patients?

Provide only medication management
Focus on speech therapy alone
Limit therapy to mobility
Address both stroke recovery and age-related health issues (Correct answer)

Correct answer: Address both stroke recovery and age-related health issues

For elderly stroke patients, post-acute care must take a holistic approach, considering not only the stroke-related deficits but also pre-existing age-related health conditions. Older adults often have comorbidities, polypharmacy, and reduced physiological reserves, which can impact recovery and require integrated management. Addressing both aspects optimizes outcomes and prevents complications in this vulnerable population.

Question 81: Which cerebral artery supplies the lateral surface of the frontal and parietal lobes, including the primary motor cortex of the upper extremity?

Anterior cerebral artery
Middle cerebral artery (Correct answer)
Posterior cerebral artery

Question 82: Which personal protective equipment (PPE) principle applies to ALL SCRN certified professionals regardless of their specific role?

PPE is optional if experienced in the field
PPE must be properly fitted, maintained, and replaced as needed (Correct answer)
Any PPE will provide adequate protection
PPE is only necessary during formal inspections

Correct answer: PPE must be properly fitted, maintained, and replaced as needed

Regardless of experience level or specific role, PPE must be properly fitted to the individual, regularly maintained in good condition, and replaced when worn or damaged. Improperly fitted or degraded PPE can provide a false sense of security.

Question 83: What is ischemic stroke?

A stroke due to a sudden drop in blood pressure
A stroke due to reduced blood flow caused by a clot (Correct answer)
A stroke caused by an infection
A stroke caused by a ruptured blood vessel

Correct answer: A stroke due to reduced blood flow caused by a clot

Ischemic stroke is the most common type of stroke, occurring when a blood clot blocks or narrows an artery that supplies blood to the brain. This blockage prevents oxygen and nutrients from reaching brain cells, leading to their damage or death. The clot can form in the brain's arteries (thrombotic) or travel from elsewhere in the body (embolic).

Question 84: What role does calibration play in maintaining technical accuracy for Stroke Certified Registered Nurse professionals?

It only matters during formal inspections
It is only necessary for new equipment
It ensures instruments and methods produce accurate, consistent results over time (Correct answer)

Question 85: What are the main causes of ischemic stroke?

Fatty deposits and blood clots (Correct answer)
Stress and dehydration
High blood pressure and infections
Severe headaches

Correct answer: Fatty deposits and blood clots

The primary causes of ischemic stroke are atherosclerosis, which involves the buildup of fatty deposits (plaque) in the arteries, and the formation of blood clots. These plaques can narrow arteries, reducing blood flow, or rupture, leading to clot formation that blocks the vessel. Clots can also travel from other parts of the body, such as the heart, to the brain.

Question 86: A stroke patient on heparin infusion for cardioembolic stroke has a PTT result of 220 seconds (therapeutic range: 60–100 seconds). What is the nurse's priority action?

Administer protamine sulfate immediately
Continue the infusion and recheck in 6 hours
Decrease the heparin rate per the protocol and notify the physician (Correct answer)
Stop the heparin and start warfarin

Correct answer: Decrease the heparin rate per the protocol and notify the physician

A supratherapeutic PTT increases hemorrhagic transformation risk; the heparin rate must be reduced per weight-based protocol and the physician notified.

Question 87: What is hemorrhagic stroke?

A stroke caused by bleeding in the brain (Correct answer)
A stroke from an allergic reaction
A stroke due to low blood sugar
A stroke caused by a clot

Correct answer: A stroke caused by bleeding in the brain

A hemorrhagic stroke occurs when a blood vessel in the brain ruptures and bleeds into the surrounding brain tissue. This bleeding directly damages brain cells and increases pressure on the brain, further impairing function. It is often associated with high blood pressure, aneurysms, or arteriovenous malformations (AVMs).

Question 88: What is the role of neuroimaging in acute care?

To locate the stroke and determine treatment (Correct answer)
To assess long-term recovery
To monitor patient vitals
To evaluate the brain's electrical activity

Correct answer: To locate the stroke and determine treatment

Neuroimaging, primarily CT scans and sometimes MRI, is indispensable in acute stroke care for rapidly diagnosing the type of stroke (ischemic vs. hemorrhagic) and pinpointing its location and extent. This information is critical for guiding immediate treatment decisions, such as whether to administer thrombolytics or consider surgical intervention. Accurate imaging ensures appropriate and timely care.

Question 89: A nurse is preparing a patient for mechanical thrombectomy. The patient's NIHSS score is 18 and CT angiography confirms large vessel occlusion. What time window is generally accepted for thrombectomy in eligible patients?

Only if tPA was given first
Within 1 hour of symptom onset
Within 3 hours of symptom onset only
Up to 6 hours, and up to 24 hours in selected patients with favorable imaging (Correct answer)

Correct answer: Up to 6 hours, and up to 24 hours in selected patients with favorable imaging

Current guidelines support thrombectomy up to 6 hours for standard eligibility and up to 24 hours for selected patients with perfusion imaging mismatch.

Question 90: How frequently should ongoing assessments be conducted in Stroke Certified Registered Nurse practice?

Only when required by external auditors
At regular intervals based on established protocols and as conditions change (Correct answer)
Only when problems are reported
Once annually regardless of circumstances

Correct answer: At regular intervals based on established protocols and as conditions change

Question 91: A patient with a posterior circulation stroke presents with vertigo, ipsilateral facial numbness, and contralateral limb ataxia. This constellation suggests involvement of which artery?

Middle cerebral artery (MCA)
Posterior inferior cerebellar artery (PICA) (Correct answer)
Basilar artery tip
Anterior cerebral artery (ACA)

Correct answer: Posterior inferior cerebellar artery (PICA)

PICA occlusion causes Wallenberg (lateral medullary) syndrome, characterized by ipsilateral facial and contralateral body sensory loss, vertigo, dysphagia, and ataxia.

Question 92: Which finding in a stroke patient most urgently indicates elevated intracranial pressure (ICP)?

SpO2 of 94% on room air
Complaint of headache rated 4/10
Temperature of 37.8°C
Cushing's triad: bradycardia, hypertension, and irregular respirations (Correct answer)

Correct answer: Cushing's triad: bradycardia, hypertension, and irregular respirations

Cushing's triad is a late, ominous sign of severely elevated ICP and impending brainstem herniation requiring immediate intervention.

Question 93: What is the target blood pressure goal during IV alteplase infusion for acute ischemic stroke?

< 160/100 mmHg
< 200/110 mmHg
< 140/90 mmHg
< 180/105 mmHg (Correct answer)

Correct answer: < 180/105 mmHg

Blood pressure must be maintained below 180/105 mmHg during and for 24 hours after IV alteplase to minimize hemorrhagic risk.

Question 94: A nurse administers 10% of the alteplase dose as an IV bolus over 1 minute. What happens with the remaining 90%?

Infused over 30 minutes
Given as a second bolus after 30 minutes
Held and administered only if symptoms worsen
Infused over 60 minutes (Correct answer)

Correct answer: Infused over 60 minutes

Standard alteplase administration is 10% as an IV bolus over 1 minute and the remaining 90% infused over 60 minutes.

Question 95: Which ion flux occurs first during the depolarization phase of ischemic neuronal injury?

Chloride efflux
Sodium influx (Correct answer)
Potassium efflux
Magnesium influx

Correct answer: Sodium influx

During ischemic depolarization, failure of the Na⁺/K⁺-ATPase pump leads to massive sodium influx, followed by water entry and cytotoxic edema.

Question 96: What role does monitoring intracranial pressure play in acute stroke care?

To track the patient's temperature
To monitor the brain's electrical activity
To prevent seizures in the patient
To manage brain swelling and prevent further injury (Correct answer)

Correct answer: To manage brain swelling and prevent further injury

Intracranial pressure (ICP) monitoring is vital in acute stroke care, especially in severe cases or hemorrhagic strokes, because brain swelling (edema) is a common and dangerous complication. Elevated ICP can compress brain tissue, reduce cerebral blood flow, and lead to further neurological damage or herniation. Monitoring allows for timely interventions to reduce pressure and protect the brain.

Question 97: A patient with ischemic stroke is found to have diabetes. Which antihypertensive class has additional benefit for secondary stroke prevention in diabetic patients?

Loop diuretics
ACE inhibitors or ARBs (Correct answer)
Alpha-1 blockers

Summarize findings verbally without written documentation
Include only positive findings to maintain optimism
Record objective findings, measurements, and professional observations factually (Correct answer)

Correct answer: Record objective findings, measurements, and professional observations factually

Question 99: A patient admitted with ischemic stroke has an LDL of 145 mg/dL. Per current stroke guidelines, what medication should be started during the acute hospitalization?

Ezetimibe monotherapy
Fibrate therapy
Niacin supplementation
High-intensity statin therapy (Correct answer)

Correct answer: High-intensity statin therapy

High-intensity statin therapy reduces recurrent stroke and cardiovascular events and should be initiated during acute hospitalization regardless of baseline LDL.

Question 100: A patient with acute ischemic stroke suddenly develops worsening neurological deficits and a MAP drop to 55 mmHg during hospitalization. What is the most likely cause?

Hyperperfusion syndrome
Benign fatigue from rehabilitation
Cerebral vasospasm
Stroke-related cardiac arrhythmia causing hemodynamic compromise (Correct answer)

Correct answer: Stroke-related cardiac arrhythmia causing hemodynamic compromise

Stroke patients are prone to cardiac arrhythmias and neurogenic cardiac dysfunction, which can precipitate hemodynamic instability and secondary neurological deterioration.

Question 101: During cerebral ischemia, the ischemic penumbra is best defined as:

Hypoperfused but potentially viable tissue surrounding the infarct core (Correct answer)
Necrotic tissue resulting from hemorrhagic transformation
The zone of reactive hyperemia following reperfusion
Irreversibly infarcted tissue at the stroke core

Correct answer: Hypoperfused but potentially viable tissue surrounding the infarct core

The ischemic penumbra is electrically silent but metabolically viable tissue surrounding the infarct core that can be salvaged with timely reperfusion.

Question 102: What defines acute care in stroke management?

Long-term follow-up care
Immediate interventions to stabilize the patient's condition (Correct answer)
Ongoing rehabilitation therapy
Supportive care during rehabilitation

Correct answer: Immediate interventions to stabilize the patient's condition

Acute care in stroke management refers to the critical period immediately following stroke onset, typically within the first few hours to days. During this phase, the focus is on rapid diagnosis, stabilizing the patient's medical condition, and implementing time-sensitive treatments to minimize brain damage and prevent complications. This includes interventions like thrombolysis or blood pressure management.

Question 103: Which factor MOST significantly affects the quality of technical outcomes in SCRN practice?

The brand of equipment being used
The time of day the procedure is performed
The practitioner's training, preparation, and attention to detail (Correct answer)

Correct answer: The practitioner's training, preparation, and attention to detail

The quality of technical outcomes depends primarily on the practitioner's level of training, thorough preparation, and careful attention to detail. While equipment matters, the professional's competence is the most significant factor.

Question 104: Lacunar infarcts are most commonly caused by:

Venous thrombosis of the superior sagittal sinus
Lipohyalinosis of small penetrating arteries (Correct answer)
Cardioembolism from atrial fibrillation
Large artery atherosclerosis of the carotid bifurcation

Correct answer: Lipohyalinosis of small penetrating arteries

Lacunar infarcts result from lipohyalinosis or microatheroma of small penetrating arteries (< 15 mm diameter), most commonly in the basal ganglia, thalamus, and internal capsule.

Question 105: Which medication is contraindicated within 24 hours of IV alteplase administration?

Anticoagulants and antiplatelet agents (Correct answer)
Antiepileptics
Antihypertensives
Osmotic diuretics

Correct answer: Anticoagulants and antiplatelet agents

Anticoagulants and antiplatelet agents are contraindicated for 24 hours after tPA to reduce the risk of hemorrhagic transformation.

Question 106: What is the role of thrombolytic therapy in acute care for ischemic stroke?

To remove the blood clot causing the stroke (Correct answer)
To decrease the risk of hemorrhagic stroke
To stabilize blood pressure
To prevent future strokes

Correct answer: To remove the blood clot causing the stroke

Thrombolytic therapy, specifically with medications like tPA, is a cornerstone of acute care for ischemic stroke. Its role is to actively dissolve the blood clot that is blocking blood flow to a part of the brain. By removing the clot, it aims to restore circulation and salvage brain tissue that is at risk of permanent damage.

Question 107: What imaging technique is typically used in hyperacute care for stroke diagnosis?

X-ray
CT scan (Correct answer)
Ultrasound
MRI

Correct answer: CT scan

A CT scan is the imaging technique of choice in hyperacute stroke care due to its rapid availability and ability to quickly differentiate between ischemic and hemorrhagic stroke. This distinction is critical because treatment strategies differ significantly (e.g., tPA for ischemic vs. blood pressure control for hemorrhagic). While MRI provides more detailed images, it takes longer and is not typically the first-line diagnostic tool in the immediate hyperacute phase.

Question 108: A patient is transferred from the ICU to the stroke unit 48 hours after a large MCA infarct. Which complication requires ongoing prophylactic nursing intervention throughout hospitalization?

Hyperthyroidism
Deep vein thrombosis (DVT) (Correct answer)
Polyuria
Hyperkalemia

Correct answer: Deep vein thrombosis (DVT)

Immobility after stroke significantly increases DVT risk; prophylaxis with compression devices and pharmacological anticoagulation (when safe) must be maintained throughout the hospital stay.

Question 109: Which mechanism accounts for the majority of hemorrhagic strokes in elderly hypertensive patients?

Cerebral amyloid angiopathy
Hypertensive lipohyalinosis with vessel rupture (Correct answer)
Rupture of a saccular (berry) aneurysm
Arteriovenous malformation rupture

Correct answer: Hypertensive lipohyalinosis with vessel rupture

Chronic hypertension causes lipohyalinosis of small penetrating vessels, making them prone to rupture and causing intracerebral hemorrhage, typically in the basal ganglia, thalamus, pons, or cerebellum.

Correct answer: Adhering to established protocols while adapting to specific conditions

Question 116: A patient receiving IV alteplase for acute ischemic stroke develops sudden severe headache and hypertension. What is the priority action?

Administer fresh frozen plasma immediately
Slow the infusion rate and monitor closely
Administer antihypertensive medication and continue infusion
Stop the infusion and obtain emergent CT head (Correct answer)

Correct answer: Stop the infusion and obtain emergent CT head

Sudden severe headache and hypertension during tPA infusion suggest hemorrhagic transformation, requiring immediate cessation and emergent CT imaging.

Question 117: In Stroke Certified Registered Nurse practice, what is the FIRST step when a safety hazard is identified in the workplace?

Immediately secure the area and report the hazard (Correct answer)
Document it for the next safety audit
Continue working and report at end of shift
Wait for a supervisor to notice the issue

Correct answer: Immediately secure the area and report the hazard

When a safety hazard is identified, the immediate priority is to secure the area to prevent injury and report the hazard through proper channels. Delaying action increases the risk of incidents.

Question 118: When conducting a risk assessment for SCRN operations, which factor should receive the HIGHEST priority?

Convenience for daily operations
Time required for safety training
Probability and severity of potential harm (Correct answer)
Cost of implementing safety measures

Correct answer: Standardized tools combined with professional observation

Question 120: What is transient ischemic attack (TIA)?

A viral infection of the brain
A temporary blockage or reduced blood flow to the brain (Correct answer)
A permanent blockage of blood flow to the brain
A heart attack

Correct answer: A temporary blockage or reduced blood flow to the brain

A Transient Ischemic Attack (TIA), often called a 'mini-stroke,' occurs when blood flow to the brain is temporarily interrupted, causing stroke-like symptoms that typically last only a few minutes to an hour and resolve completely. Although symptoms are temporary, a TIA is a serious warning sign that a full-blown stroke may occur soon, necessitating immediate medical evaluation.

Question 121: What documentation is MOST critical to maintain for safety compliance in the Stroke Certified Registered Nurse field?

Incident reports, training records, and inspection logs (Correct answer)
Annual revenue reports
Employee vacation schedules

Relying on memory for routine procedures

Correct answer: Maintaining organized, dated, and signed records of all activities, training, and incidents

Question 126: When assessment results for a Stroke Certified Registered Nurse evaluation are inconclusive, the BEST practice is to:

Delay reporting until results are favorable
Report the results as definitive anyway
Conduct additional assessment using alternative methods (Correct answer)
Discard the results and start over completely

Correct answer: Conduct additional assessment using alternative methods

Question 127: A nurse is caring for a patient with a large hemispheric ischemic stroke. To reduce the risk of malignant cerebral edema, the head of the bed should be maintained at:

60–90°
Flat (0°)
15–30° (Correct answer)
45°

Correct answer: 15–30°

Head-of-bed elevation at 15–30° optimizes cerebral venous drainage and ICP without compromising cerebral perfusion pressure.

Question 128: A SCRN notices that a stroke patient has a new onset of atrial fibrillation on the cardiac monitor. Why is this finding especially significant?

It lowers the risk of deep vein thrombosis
It is a common cause of cardioembolic stroke and may indicate the stroke's etiology (Correct answer)
It typically resolves without treatment
It always requires immediate cardioversion

Correct answer: It is a common cause of cardioembolic stroke and may indicate the stroke's etiology

Atrial fibrillation is the most common cardiac source of emboli in cardioembolic stroke, and its detection informs anticoagulation decisions.

Question 129: What is the significance of early intervention in stroke management?

Early intervention helps restore blood flow and prevent brain damage (Correct answer)
It may worsen the condition
It has no impact on recovery
It only treats the symptoms

Correct answer: Early intervention helps restore blood flow and prevent brain damage

Time is critical in stroke management, often summarized as 'time is brain.' Early intervention, particularly within the first few hours of symptom onset, allows for treatments like thrombolytic drugs (tPA) or mechanical thrombectomy to restore blood flow to the affected brain area. This rapid action can significantly limit the extent of brain damage, improve patient outcomes, and reduce long-term disability.

Question 130: A patient develops seizures 12 hours after an ischemic stroke. Which nursing intervention takes priority?

Administer an antiepileptic drug as ordered and protect the airway (Correct answer)
Increase the IV fluid rate
Perform a 12-lead ECG immediately
Restrain the patient to prevent injury

Correct answer: Administer an antiepileptic drug as ordered and protect the airway

Seizure management priorities are airway protection and prompt administration of ordered antiepileptics to terminate the seizure and prevent recurrence.

Question 131: When a SCRN professional encounters an unexpected result during a technical procedure, the FIRST action should be to:

Continue the procedure and address it later
Repeat the procedure from the beginning immediately
Report the issue without any preliminary assessment
Stop, assess the situation, and determine whether to proceed or seek guidance (Correct answer)

Correct answer: Stop, assess the situation, and determine whether to proceed or seek guidance

Question 132: What medication is commonly used for acute stroke patients to prevent complications?

Blood pressure medication
Antiplatelet drugs (Correct answer)
Sedatives
Anticoagulants

Correct answer: Antiplatelet drugs

Antiplatelet drugs, such as aspirin, are commonly used for acute ischemic stroke patients (after ruling out hemorrhage) to prevent further clot formation and reduce the risk of early recurrent stroke. They work by inhibiting platelet aggregation, making the blood less likely to clot. This helps to maintain blood flow and prevent worsening of the ischemic event.

Question 133: How should Stroke Certified Registered Nurse professionals handle technical procedures that have been updated or revised?

Only apply updates to new cases or projects
Review the updates, complete any required training, and implement the revised procedures (Correct answer)
Wait for mandatory enforcement before changing
Continue using the original method if it still works

Correct answer: Review the updates, complete any required training, and implement the revised procedures
