The equilibrium constant expression for the reversible reaction 2 X2(g) + 3 Y2(g) 

Write the following in decimal form, keeping the proper number of significant figures: 4.921 x 107

Select ALL of the following that are exact numbers:

BONUS: A 22 year old male with a diagnosis of sepsis has been receiving mechanical ventilatory support for the treatment of respiratory failure. His current settings on VC-CMV include a VT of 550 mls, R = 18 b/m, PEEP of 10 cmH20 and FiO2 of 60%. PIP is averaging 32 cmH20 and plateau pressures are at 26 cmH20. The physician wants to switch the patient to the PC-CMV mode. Where would you set your initial inspiratory pressure setting?

When the Lewis structure for PCl3 is drawn, the electron pair geometry AND molecular geometry (in that order) for the structure is

What tidal volume listed below would provide a breath of approximately 8 ml/kg of ideal body weight for the patient listed in question 18 above?

Which of the following modes of mechanical ventilation would provide all of the patient’s minute ventilation (VE) with mandatory pressure targeted breaths?

BONUS: All of the following criteria should be met before considering use of a heat and moisture exchanger (HME) for a patient on ventilatory support EXCEPT:

This question is a bonus question worth 3.5 points. If Ni0 metal changes to Ni2+ ion in a reaction, the process is called

A patient is receiving mechanical ventilation and has just received Pancuronium (Pavulon) a neuromuscular blocking (paralyzing) agent. The most important ventilator alarm to monitor at this time would be:
