recommend which of the following oxygen delivery devices:
A) Oxygen hood
B) Oxygen tent
C) 5LPM NC
D) an aerosol mask with a jet nebulizer

A water barometer is being used to record the barometric pressure. The water
within the barometer column has a meniscus formation. You would read the
barometric pressure at the:
A) Bottom of the meniscus
B) Top of the meniscus
C) Side of the meniscus
D) Top and side of the meniscus
A) Bottom of the meniscus
,The respiratory care practitioner has receive an order to administer 35% oxygen to
a post-operative craniotomy patient. The patient is semi-conscious with an
irregular breathing pattern. The most appropriate oxygen administration device
for this patient would be:
A) A 4LPM Nasal cannula
B) intubation with a 35% aerosol blow-by
C) a simple mask at 4 LPM
D) a Venturi mask
D) a Venturi mask
A cuff pressure manometer is connected to the endotracheal tube of a patient
receiving continuous mechanical ventilation. The cuff pressure reading is 24 torr
with a small air leak auscultated during inspiration. Which of the following should
be done:
A) Increase the cuff pressure
B) Maintain this set-up and reassess in 1 hour
C) Recommend changing to a larger endotracheal tube
D) Decrease the cuff pressure and reassess the leak
C) Recommend changing to a larger endotracheal tube
A 12 year old conscious, spontaneously breathing female, weighing 40kg (88lb) is
brought into the ER with a sustained cervical spine injury without any evidence of
other trauma from a motor vehicle accident. The head is secured with sandbags
,and arterial blood gas analysis shows respiratory failure. To maintain the patient's
airway, the respiratory care practitioner should recommend a:
A) 6.0mm nasal endotracheal tube
B) 8.0 mm oral endotracheal tube
C) 7.0 mm tracheotomy tube
D) 8.0 mm esophageal obturator airway tube
A) 6.0mm nasal endotracheal tube
A 22 year old male is being ventilated with a microprocessor ventilator. You are
checking his cuff with a cuff inflator and as you connect the pilot balloon thecuff
inflator, the pressure measured reads 0 torr. Your first immediate response would
be to:
A) Add 10 ml of air to the pilot balloon
B) inflate the cuff till the manometer reads 20 torr
C) reconnect the pilot balloon to the cuff inflator tightly
D) deflate the cuff and reinflate with 10 ml of air
C) reconnect the pilot balloon to the cuff inflator tightly
Which of the following could be done to minimize mean airway pressure during an
IPPB treatment?
1. Decrease the peak pressure
2. Decrease the I time
3. Increase the E time
, 4. Increase inspiratory flow
A) 1 only
B) 2 and 3 only
C) 2 and 4 only
D) all the above
D) all the above
A patient is on 60% aerosol mask and their inspiratory flow rate is determined to
be 28 LPM. What is the minimum flow rate setting required for this patient?
A) 8LPM
B) 10 LPM
C) 12 LPM
D) 15 LPM
D) 15 LPM
A chronic hypercapnic patient is in acute ventilatory failure. The physician has
asked for your recommendation in the care of this patient who is requiring
assisted ventilation. You would recommend:
A) A volume-cycled microprocessor controlled machine
B) BiPAP
C) Positive expiratory pressure mask (PEP)
