A mechanically ventilated patient with suspected ARDS has the following hemodynamic values: PAP= 32/18 mm Hg, mean PAP= 23 mm Hg, PCWP 9 mm Hg. Which conclusion is MOST appropriate? 

A patient with ARDS has a Swan-Ganz catheter in place. The following data are obtained: PAP= 40/25 mm Hg, PCWP 10 mm Hg, CI 3.0 L/min. How should this be interpreted?

Immediately after intubation in the emergency department, the capnogram shows an initial small C02 waveform that quickly declines to near zero and remains flat despite continued ventilation. What is the MOST appropriate interpretation?

34) A cloudy or opaque area in the normally clear lens of the eye is called a ________.

During CPR on an intubated adult, continuous waveform capnography shows a ETC02 of 8 mm Hg that rises abruptly to 35 mm Hg without any change in ventilator settings. What is the most likely explanation for this sudden increase?

Which change in capnography would most strongly suggest that a patient on patient-controlled analgesia (PCA) with opioids is developing respiratory depression before oxygen desaturation occurs?

35) Vision impairment as a result of old age and loss of elasticity in the lens is called ________.

A patient has a stroke volume of 70 mL and a heart rate of 90 beats/min. What is this patient’s cardiac output?

Which valve does blood pass through when moving from the right atrium to the right ventricle?

A patient on mechanical ventilation shows a normal-looking capnogram except that the absolute EtC02 is implausibly high at 80 mm Hg, while arterial blood gas analysis reveals PaC02 of 40 mm Hg. What is the BEST explanation?
