practice questions #1
Which of the following is NOT an indication for continuous mechanical ventilation?
A. MIP -20 cmH2O
B. acute ventilatory failure
C. Vt < 5 mL/kg
D. VC < 10 mL/kg
MIP -20 cmH2O
Opium PEEP therapy can be identified by all of the following EXCEPT:
A. Inflection point of a volume-pressure loop graphic
B. Acceptable oxygenation with no cardiovascular side effects
C. Increasing oxygenation with increasing plateau pressures
D. Increasing static compliance with acceptable oxygenation
Increasing oxygenation with increasing plateau pressures
All of the following could be recommended to treat a patient with a severely decreased
static compliance problem, EXCEPT:
A. inverse positive pressure ventilation
B. opium PEEP therapy
C. pressure control ventilation
D. expiratory resistance
expiratory resistance
Which of the following is NOT a primary ventilation parameter measured and displayed
to create airway graphics of continuous mechanical ventilation?
A. Flow
B. PEEP
C. Tidal volume
D. Airway pressure
PEEP
A "broken" flow/volume loop and/or volume/pressure loop will occur with:
A. airway resistance
B. overdistension
C. auto PEEP
D. airway leak
airway leak
A 32 year old female who weighs 100 kg (220 lbs.) and is 165 cm (5 ft. 6 inches) tall has
chest trauma due to a motorcycle accident. The patient has just been intubated,
sedated and paralyzed with morphine sulfate and pancuronium bromide. The physician
, asks for your immediate recommendation in ventilator settings for this patient. You
would recommend:
A. A/C mode, rate 10, tidal volume 1000 ml
B. SIMV mode, rate 8, tidal volume 900 ml
C. IMV mode, rate 14, tidal volume 800 ml
D. Control mode, rate 12, tidal volume 600 ml
Control mode, rate 12, tidal volume 600 ml
A respiratory care practitioner reviews a ventilator parameter sheet and finds that the
peak inspiratory pressure has been gradually rising for the past several hours. Which of
the following could be the cause for this change?
I. Bronchospasm
II. Increasing pulmonary compliance
III. Accumulation of secretions
IV. Increasing airway resistance
A. III only
B. I & III only
C. I, III & IV
D. I, II, III &IV
I, III & IV
A 29 year old female post-operative mitral valve replacement patient is combative on a
volume-cycled ventilator in the assist/control mode. The peak pressure alarm is
sounding with each breath. The nurse practitioner has a STAT call into the
cardiovascular surgeon. She asks for your immediate recommendation. You would
recommend which of the following?
A. Increase the peak pressure alarm limit
B. Order a STAT chest x-ray
C. Change to SIMV mode and evaluate the patient
D. Order a STAT arterial blood gas
Change to SIMV mode and evaluate the patient
A 44 year old male patient is being mechanically ventilated with a volume cycled
ventilator. You observe that there is insufficient time for the patient to exhale completely.
You would now do which of the following to correct the problem?
A. increase the flow
B. decrease the minute volume
C. add expiratory retard
D. remove mechanical deadspace
increase the flow
A 58 year old male patient is hypoxic on a volume cycled ventilator and is receiving 15
cmH2O of PEEP on an FIO2 0.60. Shortly after increasing the PEEP therapy to 18
cmH2O, the respiratory care practitioner notes the systemic blood pressure has fallen
from 110/72 torr to 94/50 torr and the cardiac output has fallen from 4.3 L/min. to 2.5
L/min. The most appropriate action at this time would be to:
A. maintain the present therapy and re-evaluate the patient in thirty minutes
B. decrease the PEEP to 15 cmH2O and increase the FIO2 to 0.70
