recommendation for this patient is to Answer: maintain the present
settings
⩥ A respiratory therapist is using a test lung to conduct a pre-operational
test of a ventilator at the following settings: Mode Assist/control FIO2
0.40 Respiratory rate 12 Flow 60 L/min VT 700 mL The exhaled tidal
volume measurement is 500 mL. Which of the following actions should
the therapist take? Answer: assess the ventilator circuit for leaks
⩥ A patient weighing 70 kg (154 lb) and 173 cm (5 ft 8 in) tall is
recently sedated and pharmacologically paralyzed. A chest radiograph
shows bilateral basilar atelectasis but is otherwise clear. Ventilator
settings are: Mode SIMV FIO2 0.50 Mandatory rate 10 VT 450 mL
Arterial blood gas results are as follows: pH 7.43 PaCO2 36 torr PaO2
,79 torr HCO3 23 mEq/L BE 0 mEq/L SaO2 96% Which of the following
modifications should the therapist recommend to the physician? Answer:
vt 700 mL rate 10 deadspace 200 mL
⩥ A patient who is oxygen-dependent travels using oxygen from an E
cylinder secured in the back seat. He carries a spare cylinder in the trunk
of his car when he plans to be out for longer periods of time. The
respiratory therapist should inform the patient that he should: Answer:
secure the spare cylinder in the backseat
⩥ A 60-kg (132-lb.) patient is receiving volume-controlled ventilation.
The respiratory therapist is asked to increase the tidal volume from 500
to 700 mL. Which of the following ventilator alarm settings should be
changed? I. low exhaled tidal volume II. high pressure limit III. high
minute volume IV. low respiratory rate Answer: I, II, and IV only
⩥ A patient using a transdermal nicotine patch omplains of local skin
irritation and insomnia. Which of the following should the respiratory
therapist first recommend? Answer: frequently rotate the site and
discontinue at night
⩥ While assisting with a therapeutic bronchoscopy for an adult patient,
the physician is suddenly unable to view any anatomy because
everything went black. Which of the following is a likely cause?
Answer: the light source is disconnected
, ⩥ A patients blood pressure monitored through an arterial catheter is
126/78 mm Hg. The transducer is mounted on a free-standing IV pole.
The bed is lowered to permit routine patient care. How will this affect
the measured blood pressure Answer: decrease systolic, decrease
diastolic
⩥ A patient who weights 60 kg (132 lb) is sedated and receiving
volume-controlled ventilation. The following information is available:
FIO2 0.35 Mandatory rate 12 VT 900 mL PEEP 5 cm H2O Peak flow 50
L/min pH 7.50 PaCO2 30 torr PaO2 100 torr HCO3 23 mEq/L BE 0
mEq/L Which of the following should the respiratory therapist decrease
to normalize the patient?s arterial blood gases? Answer: tidal volume
⩥ Data for a patient receiving mechanical ventilation are as follows:
Mode Assist/control FIO2 0.35 Mandatory rate 15 Total rate 20 VT 800
mL pH 7.57 PaCO2 25 torr PaO2 125 torr HCO3 22 mEq/L BE +1
mEq/L Which of the following should the respiratory therapist
recommend FIRST? I. Set 5 cm H2O PEEP II. Change FIO2 to 0.25 III.
Change mode to SIMV IV. Set mandatory rate to 10 Answer: III and IV
only
⩥ A patient with a size 8 mm endotracheal tube has been receiving
mechanical ventilation for 2 weeks, but weaning efforts have failed. If
there is no further improvement in ventilatory status within 48 hours, the
patient will be sent to the OR for a tracheotomy procedure. The
tracheostomy device will facilitate this patient?s care by: I. Increasing
dead space II. Decreasing airways resistance III. Decreasing upper
