The respiratory therapist should evaluate which of the following to develop a teaching plan for a
patient who will be using a small volume nebulizer at home?
A. highest grade level achieved in school
B. manual dexterity
C. spousal support
D. english speaking proficiency
B
CORRECT ANS: B
Explanation : A patient that is taking nebulizer treatments needs to be able to demonstrate
manual dexterity, and the ability to hold and manipulate the nebulizer. During the instruction,
appropriate language skills are also important but English proficiency is not required. What is
NOT important is the patient's spousal support. This will have no effect on their ability to self
administer nebulizer treatments.
Which of the following would be most beneficial in resolving microatelectasis?
A. Thoracentesis
B. Bronchoscopy
C. Percutaneous ventilation
D. Chest tubes
B
CORRECT ANS: B
,Explanation : A bronchoscopy would be most beneficial because it can ventilate and recruit
alveoli in the lung. The other options will not decrease atelectasis.
A 45 year-old patient is recovering in the intensive care unit after undergoing a surgical
procedure to repair a hernia. The patient remains unconscious. To prevent soft tissue
obstruction, the respiratory therapist should recommend a(n)
A. double-lumen endobronchial tube
B. nasopharyngeal airway
C. bite block
D. oropharyngeal airway
D
CORRECT ANS: D
Explanation : An oral pharyngeal airway is the primary mechanism used to prevent the time
from falling back and obstructing the airway. Although a double lumen endobronchial tube
would also do this, it is far too invasive and not necessary.
Quality control material has published values for pH of 7.20, PO2 of 65 mmHg. Documentation
indicates the range of pH is 0.5% and is 3% for PO2. Machine results are as follows:
pH PO2 (mmHg) Run 1 7.19 64Run 2 7.1069Run 3 7.2165
Which quality control run(s) indicate the machine is out of control?
A. Run 2 and 3
B. Run 1 and 2
C. Run 2 only
D. Run 3 only
C
CORRECT ANS: C
,Explanation : This question involves doing some math. You must look at each pH and add and
subtract 0.5%. You must do the same for the PO2, using 3%. From there you can look at the
results and determine which Run is out of control. In this case only Run two is out of control.
A respiratory therapist is considering a patient's readiness to wean from mechanical ventilation.
To determine the A-aDO2, the therapist will need which of the following?
A. CaO2 and PAO2
B. VD/VT and PAO2
C. VD/VT and ABG
D. ABG and alveolar oxygen tension
A
CORRECT ANS: D
Explanation : This question requires you to remember what is needed to calculate A-a gradient.
You only need two things - the alveolar oxygen tension (PAO2), and the arterial oxygen tension,
determined from an arterial blood gas.
A patient with increased airway resistance from a fixed upper airway obstruction would benefit
most from which of the following?
A. heliox therapy
B. aerosolized atropine
C. epinephrine
D. bronchodilator therapy
A
CORRECT ANS: A
, Explanation : A fixed upper airway obstruction means air is having difficulty moving both in and
out. It is usually caused by cancer or other non-changeable conditions. In this case the best
thing we can do is decrease airway resistance by using helium or Heliox therapy.
Evaluating MIP (maximum inspiratory pressure) is most useful in evaluating which of the
following?
A. presence of a restrictive pulmonary defect
B. presence of obstructive pulmonary defect
C. inspiratory muscle strength
D. effectiveness of cough
C
CORRECT ANS: C
Explanation : Maximum inspiratory pressure is most useful in evaluating for inspiratory muscle
strength, or the ability to sustain ventilation. To determine if a patient has a restricted
pulmonary defect one would need to do a pulmonary function test. The effectiveness of a
cough would be assessed through doing a maximum expiratory pressure maneuver, or MEP.
An air-entrainment jet nebulizer is set at 50%. The respiratory therapist analyzes the oxygen
coming from the end of the tubing and finds it is 60%. Which of the following most likely
explains this finding?
A. excess water in the tubing
B. poorly calibrated analyzer
C. leak in the tubing
D. low flow through the jet orifice
A
CORRECT ANS: A
