You are performing manual ventilation on a post-trauma victim. You note a sudden increase in pressure needed to ventilate the patient and fall in B/P from 140/80 to 80/40. Breath sounds are suddenly absent on the left side. You would most likely suspect:

Given: pH = 7.31  PaCO2 = 33  HCO3 = 14 mEq/L  PaO2 = 43  SaO2 = 58%  PECO2 = 26  Your interpretation of the blood gasses would be:

Which of the following statements is associated with the drug, Xopenex?

Pressure limit controls on volume ventilators are usually designed to limit:

25. Calculate the VD/VT   Given: Given: FIO2  = 40%      PB = 760      PaO2 = 80          PaCO2 = 78      SaO2 = 95% PvO2 = 40      Hb = 10    PECO2 = 42    VT = 800 ml    f = 12 breaths/min  

The adequacy of ventilation is best reflected by which of the following?

The foot of the bed is raised 18 inches. The patient is prone with a pillow under the waist and a pillow propping the lower legs and feet upward. What is being drained?

Given a  85 yr old COPD, respirations 36, pulse 147 with fever and CXR with consolidation of the RML. Which of the following would you now recommend given the following ABG? pH 7.28, PaC02 68 Pa02 48 on 50% 02

How many grams are in 14.6 mol sodium hypochlorite? Answer in g. Do not type units. Do not use scientific notation.

A 6’3″, 180 lb male patient is being mechanically ventilated in the control mode with FIO2 .6, a set rate of 8, and a tidal volume of 800 ml. Peak airway pressure is 33 cmH2O. Breath sounds are diminished. Results of an arterial blood gas analysis are below. A desired PaCO2 of 40 is ordered. pH = 7.28PaCO2 = 83HCO3 = 21 mEq/LPaO2 = 75 torrSaO2 = 93% On the basis of these results, the most appropriate action would be to: I. increase the peak flow rateII. increase the set rate to 16III. increase the set rate to 20IV. increase the tidal volume to 900 ml
