MEDSURG II QUIZ 9 (CVA, SPINAL
CORD INJURIES)
1. A patient has weakness on the right side and impaired reasoning after having
a cerebrovascular accident (CVA). Which part of the brain is affected?
A) Right hemisphere of the cerebrum
B) Left hemisphere of the cerebrum
C) Cerebellum
D) Brainstem
Answer: B) Left hemisphere of the cerebrum
Rationale: The left hemisphere controls reasoning and motor functions on the right side of the
body.
2. Which patient is at greatest risk for a CVA?
A) A 22-year-old athlete
B) A 45-year-old occasional smoker
C) A 65-year-old African-American man with hypertension
D) A 30-year-old woman with a history of migraines
Answer: C) A 65-year-old African-American man with hypertension
Rationale: Older African Americans with hypertension have the highest risk for CVA.
3. A patient experienced momentary confusion, dizziness, and slurred speech but
recovered in 2 hours. Which diagnostic assessment is most helpful?
A) Blood pressure measurement
B) Headache history
, C) MRI results
D) Nausea presence
Answer: C) MRI results
Rationale: MRI is the preferred imaging to confirm diagnosis of TIA and rule out other causes.
4. A nurse is updating a teaching plan for a patient who sustained a TIA. What
should the nurse include?
A) Daily aspirin dose
B) Long rest periods
C) Fluid restriction
D) Avoid aspirin
Answer: A) Daily aspirin dose
Rationale: Aspirin reduces platelet aggregation and prevents further attacks.
5. What is the purpose of warfarin (Coumadin) for a patient recovering from a
CVA?
A) Dissolves existing clots
B) Prevents formation of new clots
C) Vasodilates cerebral arteries
D) Increases blood cell production
Answer: B) Prevents formation of new clots
Rationale: Warfarin is an anticoagulant that prevents new clots but does not dissolve existing
ones.
6. How should a CVA resulting from a ruptured vessel in the left hemisphere be
classified?
A) Ischemic stroke
B) Hemorrhagic, intracerebral
C) Subarachnoid hemorrhage
D) Embolic stroke
Answer: B) Hemorrhagic, intracerebral
Rationale: Ruptured vessel within brain tissue indicates an intracerebral hemorrhage.
