The area identified by vertical lines on the pressure-time scalar shown here represents  

A 60 kg patient has been mechanically ventilated for 24 hours following a traumatic injury with pulmonary contusions. He is on the following settings with an ABG as shown here:            Mode: VC-AC                                       FiO2:    0.60            Mandatory Rate: 8 bpm                        Mandatory Vt:  540 mL            Total Rate:  14 bpm                               PEEP: 5 cmH2O            Peak Flow:  40 Lpm                               ABG:  pH 7.37/ PaCO2 42/ PaO2 56/ HCO3 22The most appropriate ventilator change to improve the PaO2 is to

Which of the following patients is most likely to require mechanical ventilation due to a reduction in ventilatory capacity?

A 60 kg patient has been intubated following admission for a drug overdose. He continues to be unresponsive to stimuli. He is on the following settings with an ABG as shown here:Mode: PC-AC                                       FiO2:    0.40 Mandatory Rate: 12 bpm          Total Rate:  12 bpm               Mandatory Vt:  450 mL  Pinsp (delta P): 13 cmH2O         PEEP: 5 cmH2O                         Insp Time:  0.9 sec                     ABG:  pH 7.30/ PaCO2 52/ PaO2 106/ HCO3 22 The physician asks for your input on strategies to reduce the PaCO2. Which of the following would be an appropriate recommendation for this patient?

You obtain the following ABG 30 minutes after intubating a 54 yo patient with pneumonia in the RML and RLL. pH 7.36, PaCO2 57 mmHg, PaO2 95 mmHg, HCO3 33 mEq/L.Ventilator settings are: Mode:  VC-SIMV            Set rate 12 bpm            Total rate 12 bpm         Vt 550 mL (7 mL/Kg)      PEEP: 5 cmH2O           FiO2: 50%                     PS: 5 cmH2O                 Peak flow:  60 Lpm Based on this information the most appropriate action for this patient would be which of the following?

I understand that I am not permitted to use notes, textbook, or electronic resources to answer questions during the exam. I also understand that I am not permitted to discuss or share exam material with classmates until after the exam has closed for all students. If I violate these rules, my actions will be reported and may result in expulsion from the program.

The RT is preparing to convert a patient from volume control to pressure control ventilation on a PB 840 ventilator. While in VC, the RT obtains the following values:            Vt 650 mL         Flow 50 Lpm       PIP: 36 cmH2O     Pplat: 30 cmH2O       PEEP: 10 cmH2OWhat inspiratory time will achieve 4 time constants (tau) for this patient? _______ seconds
