All of the following are functional benefits of the EHR EXCEPT:

Your patient is an obese 39-year-old woman involved in a lateral-impact motor vehicle collision. Which of the following should you remember when assessing and treating this patient?

A) Relative to body size, this patient can tolerate a larger amount of hemorrhage before showing signs of shock. B) This patient will tolerate blood loss well, as only non-vital tissues will become ischemic. C) Relative to body weight, a smaller amount of hemorrhage may result in shock. D) Blood volume increases proportionally with body weight, and the patient will experience signs of shock consistent with the classic stages of hemorrhage.

What mechanical criteria should be used to establish the actual PEEP setting for a mechanically ventilated patient? I. During a recruitment maneuver, the upper inflection point determines the ideal PEEP level. II. During a recruitment maneuver, the lower inflection point determines the optimal PEEP. III. The pressure-volume loop helps determine the best PEEP/ Vt combination. IV. The optimal PEEP

corresponds with the best lung compliance along the deflation limb following a recruitment maneuver. A. I, II only B. III, IV only C. I, II, III only D. II, III, IV only
