You would 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
ANS: B)Oxygen tent
2.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
ANS: A)Bottom of the meniscus
3.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
ANS: D)a Venturi mask
4.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
ANS: C)Recommend changing to a larger endotracheal tube
5.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 recom-
mend 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
ANS: A)6.0mm nasal endotracheal tube
6.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
ANS: C)reconnect the pilot balloon to the cuff inflator tightly
7.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
ANS: D)all the above
8.A patient is on 60% aerosol mask and their inspiratory flow rate is deter-
mined 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
ANS: D)15 LPM
9.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
