Cerebrovascular NCLEX Questions and Answers

1.

What is the primary symptom of an ischemic stroke?
- A.
  
  Severe headache
- B.
  
  High fever
- C.
  
  Sudden confusion
- D.
  
  Muscle weakness
Correct Answer
C. Sudden confusion

Explanation
Sudden confusion is a primary symptom of an ischemic stroke. This symptom arises because ischemic strokes occur when blood flow to a part of the brain is obstructed, typically by a clot, disrupting brain function. The affected area of the brain cannot perform its normal functions, leading to sudden symptoms like confusion, difficulty speaking, or understanding speech. Immediate recognition and treatment are critical to minimize brain damage and improve recovery outcomes, emphasizing the need for rapid response to these symptoms.

Which medication is commonly used to treat acute ischemic stroke?
- A.
  
  Aspirin
- B.
  
  Warfarin
- C.
  
  Tissue plasminogen activator
- D.
  
  Acetaminophen
Correct Answer
C. Tissue plasminogen activator

Explanation
Tissue plasminogen activator (tPA) is commonly used to treat acute ischemic stroke. It works by dissolving the blood clot blocking blood flow to the brain, which is crucial during the first few hours of a stroke. tPA is most effective when administered within a 4.5-hour window from the onset of stroke symptoms, as it can significantly reduce the severity of the stroke's effects and improve recovery chances. This treatment highlights the importance of quick stroke identification and emergency medical response.

What does FAST stand for in stroke response?
- A.
  
  Face, Arm, Speech, Time
- B.
  
  Fast Action Saves Time
- C.
  
  Focus, Assess, Stabilize, Treat
- D.
  
  Facial drooping, Arm weakness, Stability loss, Talking difficulties
Correct Answer
A. Face, Arm, Speech, Time

Explanation
FAST stands for Face, Arm, Speech, Time, and is a mnemonic used to help recognize the signs of a stroke quickly. "Face" checks for facial drooping, "Arm" assesses if one arm is weak or numb, "Speech" looks for slurred or strange speech, and "Time" reminds to call emergency services immediately if any symptoms are present. This acronym is crucial in promoting rapid detection and response, which can significantly affect the outcome for stroke patients by speeding up the delivery of critical care.

What is a major risk factor for hemorrhagic stroke?
- A.
  
  Hypotension
- B.
  
  Hyperactivity
- C.
  
  Hypertension
- D.
  
  Hyperthermia
Correct Answer
C. Hypertension

Explanation
Hypertension, or high blood pressure, is a major risk factor for hemorrhagic stroke. It can cause weakened arteries in the brain to rupture, leading to bleeding within brain tissues. This type of stroke is less common than ischemic strokes but is more deadly and requires immediate medical attention. Managing blood pressure through lifestyle changes and medication can significantly reduce the risk of this severe condition, emphasizing the importance of regular health screenings.

5.

Which diagnostic test is crucial for identifying a stroke?
- A.
  
  Electrocardiogram
- B.
  
  MRI of the brain
- C.
  
  Complete blood count
- D.
  
  X-ray of the chest
Correct Answer
B. MRI of the brain

Explanation
An MRI of the brain is crucial for identifying a stroke as it provides detailed images of brain tissue, allowing healthcare providers to determine the type of stroke and the affected areas. MRI scans can distinguish between ischemic and hemorrhagic strokes by showing either blood flow blockage or bleeding in the brain. This diagnostic tool is vital in planning the appropriate treatment strategy, which can be significantly different depending on the stroke type.

What is the purpose of a carotid endarterectomy?
- A.
  
  To monitor heart function
- B.
  
  To remove plaque from the carotid artery
- C.
  
  To assess lung function
- D.
  
  To repair damaged brain tissue
Correct Answer
B. To remove plaque from the carotid artery

Explanation
A carotid endarterectomy is a surgical procedure used to remove plaque from the carotid artery, which is a major artery in the neck that supplies blood to the brain. This procedure is recommended when there is significant narrowing of the carotid artery due to plaque buildup, which poses a high risk for stroke. By removing the plaque, the surgery aims to prevent future strokes by improving blood flow to the brain, highlighting its preventative role in stroke management.

7.

Which type of stroke involves bleeding within the brain?
- A.
  
  Ischemic
- B.
  
  Hemorrhagic
- C.
  
  Transient ischemic attack
- D.
  
  Embolic
Correct Answer
B. Hemorrhagic

Explanation
Hemorrhagic stroke involves bleeding within the brain and occurs when a blood vessel in the brain bursts, leading to bleeding (hemorrhage) that damages brain cells. The pressure from the leaked blood can cause further harm by compressing surrounding brain tissue, which can be fatal if not treated promptly. This type of stroke is associated with high blood pressure, aneurysms, arteriovenous malformations, or head injury, and requires different treatment strategies compared to ischemic strokes, typically focusing on controlling the bleeding and reducing pressure in the brain.

What is a common long-term complication of stroke?
- A.
  
  Diabetes
- B.
  
  Pneumonia
- C.
  
  Cognitive impairment
- D.
  
  Ulcers
Correct Answer
C. Cognitive impairment

Explanation
Cognitive impairment is a common long-term complication of stroke. This condition includes problems with memory, thinking, language, judgment, and behavior. Strokes can cause permanent damage to brain areas responsible for these functions, depending on the location and severity of the stroke. Cognitive impairment can significantly affect a person's ability to perform daily activities and impact their quality of life, making rehabilitation and continued care essential components of post-stroke treatment.

In managing stroke, what is the primary purpose of anticoagulant therapy?
- A.
  
  To reduce pain
- B.
  
  To prevent further blood clot formation
- C.
  
  To lower blood pressure
- D.
  
  To increase heart rate
Correct Answer
B. To prevent further blood clot formation

Explanation
Anticoagulant therapy in managing stroke primarily aims to prevent further blood clot formation. In cases of ischemic stroke, where clots block blood vessels in the brain, anticoagulants help reduce the risk of new clots and prevent existing clots from enlarging. This treatment is crucial for preventing additional strokes, which can compound brain damage and impair recovery. Monitoring and managing the dosage and type of anticoagulant are critical due to the risk of excessive bleeding, particularly in patients who have had a hemorrhagic stroke.

10.

Which condition is a temporary episode that mimics stroke-like symptoms but does not cause permanent damage?
- A.
  
  Migraine
- B.
  
  Seizure
- C.
  
  Transient ischemic attack
- D.
  
  Cardiac arrest
Correct Answer
C. Transient ischemic attack

Explanation
A Transient Ischemic Attack (TIA), often called a mini-stroke, mimics stroke-like symptoms but does not cause permanent damage. TIAs occur when there is a temporary decrease in blood supply to part of the brain, resulting in short-lived symptoms that resemble those of a stroke. Recognizing and treating TIAs is crucial as they often precede full-blown strokes. Effective management of TIAs can help prevent future strokes by addressing underlying risks and conditions such as arterial blockages or heart disease.
