Which of the following is most appropriate therapy for this pt? correct answer: Pentamidine (NebuPent) via Respigard once every 4 weeks An intubated pt is being mechanically ventilated via a volume neb.

Over the last hour, the pt's respirations have become irregular and shallow. ABG's show: pH: 7.24 PaCO2: 86 mmHg PaO2: 89 mmHg HCO3: 36 The most appropriate recommendation: correct answer: decrease the O2 liter flow An RT is asked to assess a pt with history of CO2 retention & air trapping.

Most acceptable action? correct answer: Recalibrate the analyzer to accommodate this unusual value An adult pt is orally intubated and receiving continuous MV.
