Mrs. Blossom is a 57-year-old female who presented to the Emergency Room with new onset Atrial Fibrillation with Rapid Ventricular Response (RVR). She is admitted to the cardiac telemetry unit after being converted to normal sinus rhythm with a calcium channel blocker (diltiazem). When you enter the room to assess Mrs. Blossom, her daughter looks at you concerned and says “mom’s acting kinda funny.”

What nursing assessments should be completed at this time?
VIEW ANSWER
Full set of vital signs (Temp, HR, BP, RR, SpO2)
Should probably get a 12-lead EKG
Assess symptoms using PQRST or OLDCARTS
You assess Mrs. Blossom to find she has a left sided facial droop, slurred speech, and is unable to hold her left arm up for more than 3 seconds.

What is/are your priority nursing action(s) at this time?
VIEW ANSWER
Call a Code Stroke (or whatever the equivalent is at your facility) to initiate response of the neurologist or Stroke team.
Notify the charge nurse to help you obtain emergency equipment if you don’t already have it at the bedside to be prepared in case of emergency

What may be occurring in Mrs. Blossom?
VIEW ANSWER
She may be having a stroke
You call a Code Stroke and notify the charge nurse for help. You obtain suction to have at bedside just in case. The neurologist arrives at bedside within 7 minutes to assess Mrs. Blossom. He notes her NIH Stroke Scale score is 32. He orders a STAT CT scan, which shows there is no obvious bleed in the brain.

Bloom's Taxonomy: Analysis
What are the possible interventions for Mrs. Blossom at this time?
VIEW ANSWER
Since there is no bleed evident on scan, Mrs. Blossom would qualify for a thrombolytic like tPA (alteplase) or for surgical intervention, as long as there are no contraindications
Critical Thinking Check
Bloom's Taxonomy: Comprehension
What are the contraindications for thrombolytics like tPA (alteplase)?
VIEW ANSWER
Recent surgery, current or recent GI bleed within the last 3 months, excessive hypertension, evidence of cerebral hemorrhage
You administer tPA per protocol, initiate q15min vital signs and neuro checks. You stay with the patient to continue to monitor her symptoms.
Critical Thinking Check
Bloom's Taxonomy: Comprehension
What are possible complications of tPA administration? What should you monitor for?
VIEW ANSWER
Bleeding, especially into the brain or a GI bleed
She may bruise easily or bleed from IV sites or her gums
Monitor for s/s bleeding or worsening stroke symptoms, which may indicate a hemorrhagic stroke has developed.
After 2 hours, Mrs. Blossom is showing signs of improvement. She is able to speak more clearly, though with a slight slur. She is still slightly weak on the left side, but is able to hold her arm up for 10 seconds now. Her NIHSS is now 6. Mrs. Blossom’s daughter asks you why this happened.

Bloom's Taxonomy: Analysis
What would you explain has happened to Mrs. Blossom physiologically?
VIEW ANSWER
Because of her new onset atrial fibrillation, the blood was likely pooling in her atria because they were just quivering and not contracting. When blood pools, it clots. When she was converted back into a normal rhythm and her atria began contracting again, that likely dislodged a clot, which went to her brain.
The clot in her brain caused brain tissue to die → ischemic stroke.
Two days later, Mrs. Blossom has recovered fully. She will be discharged today on Clopidogrel and Aspirin, plus a calcium channel blocker, with a follow up appointment in 1 week to see the neurologist.

What education topics should be included in the discharge teaching for Mrs. Blossom and her family?
VIEW ANSWER
Anticoagulant therapy is imperative to prevent further clots from forming within Mrs. Blossom’s atria if she stays in Atrial Fibrillation.
They should be taught the signs of a stroke (FAST) and call 911 if they notice them.
They should be taught signs of Atrial Fibrillation with RVR and be sure to go to the hospital if this occurs – the patient is at higher risk for stroke.
