A 58-year-old man comes to the emergency department due to sudden onset of severe right leg pain several hours ago; the leg has since become numb.  He has never had similar symptoms and has no history of trauma, fever, or chills.  The patient recently had an acute anterior wall myocardial infarction that resulted in cardiogenic shock; he is undergoing cardiac rehabilitation.  Temperature is 36.7 C (98.1 F), blood pressure is 120/70 mm Hg, pulse is 90/min and regular, and respirations are 16/min.  Cardiopulmonary examination is unremarkable.  Compared with the left leg, the right leg appears pale and is cool to the touch.  In the right lower extremity, the popliteal pulse is normal, but more distal pulses are not palpable.  Pulses in the other extremities are normal.  Neurologic examination shows loss of sensation over the dorsum of the right foot and mild weakness with dorsiflexion.  Which of the following is the most likely cause of this patient's symptoms?

Which statement is correct concerning neurological assessment during post-resuscitation management?Dilated unresponsive pupils, hypertension, bradycardia, respiratory irregularities, or apnea may indicate cerebrat hemiationProlonged hypoventilation is suggested for imminent cerebral herniation Hypothermia should be elicty avoided. Seizures should not be treated21. Which statement concerning ventricular tachycardia is NOT correct?Ventricular tachycardia is very common in childrenVentricular tachycardia most often occurs in children with underlying cardiac disease or in children who have had heart surgeryVentricular tachycardia can result from electrolyte disturbabcesVentricular tachvcardia is a wide complex rhythm
