Question 1

Vasospasm after subarachnoid hemorrhage peaks at which time frame following the initial bleed?

Accepted Answer

Days 4–14 (peak days 7–10)

Answer

Cerebral vasospasm after SAH typically occurs between days 4–14, with the highest incidence around days 7–10.

Question 2

Which medication regimen is standard to reduce vasospasm-related ischemia after subarachnoid hemorrhage?

Accepted Answer

Nimodipine 60 mg orally every 4 hours for 21 days

Answer

Nimodipine 60 mg orally every 4 hours for 21 days is the evidence-based standard to reduce vasospasm-related cerebral ischemia after SAH.

Question 3

A patient with SAH develops delayed cerebral ischemia. The nurse implements 'Triple-H therapy.' This refers to:

Accepted Answer

Hypertension, hypervolemia, hemodilution

Answer

Triple-H therapy (hypertension, hypervolemia, hemodilution) aims to increase cerebral perfusion in vasospasm-related delayed ischemia.

Question 4

A patient presents with sudden onset of diplopia, dysphagia, ataxia, and ipsilateral facial numbness with contralateral body numbness. The nurse recognizes this as:

Accepted Answer

Wallenberg (lateral medullary) syndrome

Answer

Wallenberg syndrome (lateral medullary infarction) presents with ipsilateral facial sensory loss, contralateral body sensory loss, dysphagia, hoarseness, and ataxia.

Question 5

Which stroke scale is used at the bedside by nurses to quantify stroke severity and guide acute treatment decisions?

Accepted Answer

NIH Stroke Scale (NIHSS)

Answer

The NIH Stroke Scale (NIHSS) is the standardized bedside tool used to quantify acute stroke severity across 15 neurological domains.
