Janet, age 65, has a history of hypertension, hypercholesterolemia, and atrial fibrillation. She returns to the telemetry unit at 9:30 a.m. after a diagnostic cardiac catheterization. At 10 a.m., she develops a right facial droop, garbled speech, and right-sided paralysis of her upper extremity. Her vital signs are BP 200/110, T 98.4, P 86, R 22. She weighs 56 kg. The nurse notifies the stroke team. At 10:40 a.m., a stat CT scan of the brain shows no evidence of an intracerebral hemorrhage. Lab values are hemoglobin 13.4 and hematocrit 39.6; platelet count 180,000; prothrombin time 13.6; international normalized ratio 1.1; partial thromboplastin time 25; and glucose 210. She is given labetalol 10 mg IV. At 11 a.m., Janet’s blood pressure is 170/90 and she receives IV recombinant tissue plasminogen activator (rtPA).
Janet’s stroke is most likely due to:
If the neurologist orders IV rtPA of 0.9 mg/kg for Janet, the bolus dose would be:
Which should be administered to Janet to reduce the risk of developing an intracerebral hemorrhage associated with rtPA administration for an acute ischemic stroke?
After rtPA administration, the nurse should monitor Janet for:
