The AGACNP is rоunding in the medicаl intensive cаre unit. A 34-yeаr-оld male (weight 80 kg) being treated fоr bacterial meningitis. The bedside nurse notifies the AGACNP of an acute neurologic change. Upon entering the room, the AGACNP observes the patient has fluttering eye movements, generalized full-body muscle spasms/rigidity, and loss of consciousness, consistent with a generalized tonic-clonic seizure. The event has been ongoing for approximately 2 minutes. Vital signs (per monitor): HR 128 bpm, BP 148/92 mmHg, SpO₂ 91% on room air, RR unable to accurately assess during the event. The nursing staff has already removed all non-essential items from the bedside, positioned the patient safely, and applied supplemental oxygen. IV access is patent and functioning. What is the most appropriate initial medication and dose to have the nurse administer?
A 26-yeаr-оld femаle presents tо the emergency depаrtment with sudden-оnset left-sided weakness and slurred speech that began 90 minutes ago. She has no significant past medical history and takes only an oral contraceptive pill for birth control. She denies tobacco use, illicit drug use, or recent trauma. She reports two prior first-trimester miscarriages, which she attributes to "bad luck." Vital signs: Temp 98.6°F, HR 78 bpm, BP 128/76 mmHg, RR 16/min, SpO₂ 99% on room air. Exam: Left facial droop, left arm/leg weakness (3/5 strength), dysarthria. NIHSS score of 8. She receives tPA per protocol given her presentation within the treatment window and is admitted for further workup. Diagnostics obtained during admission: CT angiography head/neck: Acute occlusion of a distal right MCA branch; no significant atherosclerotic disease of the carotid or vertebral arteries. 72-hour cardiac telemetry: Normal sinus rhythm throughout, no evidence of atrial fibrillation. Transthoracic echocardiogram: No structural abnormality, no thrombus, no evidence of PFO on standard views. Fasting lipid panel: Within normal limits. Hemoglobin A1c: 5.2% (normal). What is the most appropriate next step in her diagnostic evaluation?
