Which of the following provides the most stable patent airway for through which a patient can be manually ventilated?

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

Calculate the VD/VT given the following: pH = 7.31    PaCO2 = 33   HCO3 = 14 mEq/L    PaO2 = 43    SaO2 = 58%    PECO2 = 26 

Given a history of a difficult intubation, which of the following should be readily available at extubation?

A firefighter is brought to the ED after performing a search and rescue in a burning structure. A nurse places a pulse ox on the firefighters finger, and the reading is 93%. The physician orders and ABG, and notes that the SaO2 on the ABG is only 73%. Which of the following is the most likely explanation of the difference?

Which of the following is the approximate total flow that would be delivered from a 28% venturi mask operating at 12 L/min?

You are caring for a mechanically ventilated patient. Flow is 80, Peak Pressure 40, Pplat 20, VT 500, PEEP 5. The patient is orally intubated with a number 8.0 ET tube and is currently ventilated in PRVC mode. Calculate STATIC compliance:

The “water seal” of a chest drainage system: I. works only when suction is used   II. acts as a one-way valve preventing re-entry of air into the pleural space   III. is only necessary if an “air-leak” is present   IV. presents a resistance to exhalation

You are preparing to transport a patient via helicopter (non pressured cabin). As the craft gains altitude, what is the likely effect on the patient’s PO2?

Which of the following ABG values would be considered normal in a patient with known severe COPD? All values are pH, PCO2, PO2, and HCO3.
