Which of the following scenarios should the
respiratory therapist discontinue beta
sympathomimetic aerosol therapy?
A. A COPD patient is smoking cigarettes between
therapy
B. An asthmatic patient has a peak flow rate that is
75% of predicted or better
C. A pediatric patient does not cooperate with the
therapy
D. The patient experiences nausea and tingling in
their extremities - ANSWER-The correct answer is : D
Before obtaining a MIP value with a pressure
manometer, the respiratory therapist notes the
needle is pointing at a positive pressure of 7 cm H2O
prior to the maneuver. During the MIP maneuver,
the needle reaches -20 cmH2O. The therapist should
,A. record a MIP of -27 cmH2O
B. record and MIP of -20 cmH2O
C. record a MIP of -13 cmH2O
D. repeat the maneuver five more times - ANSWER-
The correct answer is : A
A patient who is receiving mechanical ventilation in
the assist/control mode with a PEEP of 10 cmH2O is
being manually ventilated during a transport to CT
scan. During the transport, the respiratory therapist
notices desaturation and feels the PEEP should be
increased. To do this, the therapist should
A. increase oxygen flow rate to the bag
B. cover the exhalation port
C. squeeze the bag at a higher rate
D. increase the tension on the PEEP spring -
ANSWER-The correct answer is : D
A patient with diabetes has significant respiratory
distress. Arterial blood gases reveal a pH of 7.10,
PaCO2 of 29 torr, and a PaO2 of 81 torr. The patient
,has a spontaneous tidal volume of 700 mL and a
respiratory rate of 30/min. The patient is receiving
100% oxygen by an air entrainment device with the
flow at 15 L/min. Which of the following will help the
patient and is the most appropriate action?
A. switch to a Venturi mask at FIO2 0.5 with a flow
set at 12 L/min
B. increase flow rate to 25 L/min
C. employ a tandem air-entrainment device
D. sedate the patient - ANSWER-The correct answer
is : C
If a pressure-cycled mechanical ventilator had a leak
in the circuit, what would the respiratory therapist
expect to see?
A. The pressure monometer would have a negative
deflection during each breath
B. Peak pressures would decrease
C. The mechanical breaths would not cycle off as
expected
, D. The flowrate would automatically increase to
compensate - ANSWER-The correct answer is : C
What would occur on a time-cycled ventilator with a
fixed rate if the inspiratory flow rate were reduced?
A. decrease in inspiratory time
B. decrease in tidal volume
C. increase in inspiratory time
D. increase in tidal volume - ANSWER-The correct
answer is : B
Which of the following indicate a patient is ready to
wean from mechanical ventilation?
A. VT of 6 mL/kg
B. A-aDO2 of 380 mmHg
C. RSBI 138
D. MIP of -12 cmH2O - ANSWER-The correct answer
is : A
