Version Grade A+!
a. manual dexterity Correct Answer: 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. manual dexterity
b. highest grade level achieved in school
c. spousal support
d. English speaking proficiency
d. bronchoscopy Correct Answer: Which of the following would be most
beneficial in resolving microatelectasis?
a. chest tubes
b. percutaneous ventilation
c. thoracentesis
d. bronchoscopy
b. oropharyngeal airway Correct Answer: 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. oropharyngeal airway
c. bite block
d. nasopharyngeal airway
d. Run 2 only Correct Answer: 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:
Run 1: pH 7.19, PO2 64
Run 2: pH 7.10, PO2 69
Run 3: pH 7.21, PO2 65
Which quality control run(s) indicate the machine is out of control?
a. Run 1 and 2
b. Run 2 and 3
c. Run 3 only
d. Run 2 only
a. ABG and alveolar oxygen tension Correct Answer: 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. ABG and alveolar oxygen tension
,b. VD/VT and PAO2
c. CaO2 and PAO2
d. VD/VT and ABG
c. heliox therapy Correct Answer: A patient with increased airway resistance
from a fixed upper airway obstruction would benefit most from which of the
following?
a. bronchodilator therapy
b. epinephrine
c. heliox therapy
d. aerosolized atropine
d. inspiratory muscle strength Correct Answer: Evaluating MIP (maximum
inspiratory pressure) is most useful in evaluating which of the following?
a. presence of a restrictive pulmonary defect
b. effectiveness of cough
c. presence of obstructive pulmonary defect
d. inspiratory muscle strength
b. excess water in the tubing Correct Answer: 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. poorly calibrate analyzer
b. excess water in the tubing
c. low flow through the jet orifice
d. leak in the tubing
a. examine the ventilator circuit for proper connections Correct Answer: During
a preoperational test of the ventilator with a test lung, the respiratory therapist
notes a return tidal volume of 600 cc. Ventilator settings are:
Mode: Assist/control
FiO2: 0.50
Mandatory rate: 10
VT: 750 mL
What action should the therapist take?
a. examine the ventilator circuit for proper connections
b. obtain a larger test lung
c. increase the set tidal volume to 900 mL
d. obtain a smaller test lung
d. change the fuel cell Correct Answer: During the preoperational test of the
ventilator, the respiratory therapist notices the galvanic analyzer on the
ventilator is reading erroneously low. Which of the following can the respiratory
therapist do to correct the problem?
