0 - ArchivalUser - 08-28-2014 Q36 Ans: C C) Noninvasive positive pressure ventilation We stick to C? Acute exacerbation of COPD Numerous studies have shown that Noninvasive positive pressure ventilation (NPPV) can reduce the need for intubation, length of the hospital stay, and also in-hospital mortality rate in patients presenting with acute exacerbations of COPD. Several systematic reviews have confirmed that NPPV reduces in-hospital mortality and decreases the need for endotracheal intubation in patients who have acute, severe COPD exacerbations. A systematic review concludes that patients who benefit most from NPPV treatment were those with severe exacerbations as manifested by a pH of < 7.3 0 - ArchivalUser - 08-28-2014 Ok this block is done!

A 68-year-old man is brought to the emergency department by ambulance 20 minutes after he collapsed while shoveling snow on his driveway. The patient's daughter witnessed the collapse and immediately began mouth-to-mouth resuscitation and cardiac compressions, but her father did not regain consciousness. Paramedics arrived 5 minutes later, but the patient was pulseless and apneic. He was intubated and cardiac compressions were continued. Paramedics were unable to start an intravenous line, but did administer atropine and epinephrine via endotracheal tube. Medical history provided by the daughter is remarkable for type 1 diabetes mellitus, hypertension, and a myocardial infarction 5 years ago. Daily medications include furosemide, insulin, metoprolol, and an 81-mg aspirin. During transport the cardiac monitor showed asystole. Fingerstick glucose concentration was 90 mg/dL. Intravenous access was established and 0.9% saline was initiated. On arrival the patient is intubated with ongoing cardiac compressions. Cardiac monitor is unchanged. Which of the following factors most strongly indicates a poor prognosis? A) Bystander cardiopulmonary resuscitation B) Cardiac monitor showing asystole C) History of type 1 diabetes mellitus D) Lack of prehospital intravenous medication administration E) Time elapsed before arrival of paramedics Ans) B "Previous studies of outcome as a function of the initial electrophysiologic mechanisms recorded at the scene of prehospital cardiac arrest have demonstrated that Bradyarrhythmias and Asystole have the worst prognosis." 0 - ArchivalUser - 08-29-2014 Q 31 the answer is D confirmed by NBME 0 - ArchivalUser - 08-29-2014 Can u please discuss answers of question 6-10 Thanks |
