Case Question:

A 76-year-old, previously healthy woman presents to the hospital with a new onset gaze palsy, difficulty with speech, unilateral weakness / numbness, somnolence, and confusion.

These symptoms began suddenly about 30 minutes ago while she was giving a talk at a senior citizens meeting.

Her initial National Institute of Health Stroke Scale (NIHSS) score is determined to be 14.

What do the 2018 AHA guidelines recommend with regards to initial imaging and treatment of the above patient?

Answer Options:

If her initial brain imaging exhibits extensive regions of hypoattenuation, do not administer intravenous thrombolysis; proceed directly to endovascular thrombectomy.

As long as time to intravenous thrombolysis is not delayed, perform a CT angiogram instead of a non-contrast CT scan as her first imaging study.

Initiating brain imaging within 30 minutes of arrival at the emergency department is a newly added time-sensitive system goal.

If a non-contrast head CT shows no hemorrhage: based on her high pre-stoke level of function in combination with a high NIHSS score, she should undergo immediate endovascular clot removal rather than intravenous thrombolysis.
