ABG's show:

pH: 7.24

PaCO2: 86 mmHg

PaO2: 89 mmHg

HCO3: 36

The most appropriate recommendation Answer decrease the O2 liter flow 5.An RT is asked to assess a pt with history of CO2 retention & air trapping.The pt complains that he has become increasingly SOB and is having difficulty coughing up secretions. Upon auscultation, the therapist notes scattered coarse crackles and an occasional expiratory wheeze. Most appropriate Answer - Aerosol bronchodilator with PEP therapy 6.28 week gestation neonate is being manually ventilated following delivery. Chest excursion is poor despite respiratory ventilation with high peak pres- sures. Most appropriate action Answer Intubate the patient 7.Following a traumatic nasal intubation, the pt begins to bleed profusely from the nasopharynx. The RT should Answer Keep the NT tubes cuff inflated and suction pharynx as needed 8.A pt's PaO2 measured by ABG is 255 mmHg. The analyzer on which the 2 / 4

sample was analyzed is calibrated to a PaO2 of 150 mmHg. Most acceptable action Answer Recalibrate the analyzer to accommodate this unusual value 9.An adult pt is orally intubated and receiving continuous MV. While perform- ing a routine cuff pressure measurement, the RT observes that the cuff pres- sure monometer's indicator needle continuously reads zero. No vent alarms are activated and the pt appears to be resting. The RT should do Answer Replace cuff monometer 10.A pt in ICU requires aggressive fluid and electrolyte replacement therapy. Implementation of which of the following would be most appropriate to eval- uate the effectiveness of therapy Answer ECG monitoring 11.Data obtained from an orally intubated, MV adult pt are as follows: 8:00 AM

A cuff pressure reading of 4 cmH2O was recorded at the time of initial assessment.The most likely finding of this cuff pressure is Answer The pt is at high risk for aspiration 13.If the airway resistance of a pt who is being MV via a volume ventilator increases, which of the following would also increase
