A respiratory therapist is assisting a physician with endotracheal intubation. Which
of the following should be used INITIALLY to confirm tracheal intubation?
A. cm marking of the endotracheal tube
B. observable condensation in the tube
C. pulse oximetry
D. colorimetric capnography - ANSWERS: D. colorimetric capnography
Colorimetric capnography assesses the presence of CO2 and provides confirmation
of tracheal intubation when CO2 is detected.
A respiratory therapist is asked to review a newborn's history. The following
information is available about the first few minutes after birth:
1 minute
acrocyanosis
70/min
cough
weak
20/min
5 Minutes
pink
110/min
,2|Page
cough
active motion
40/min
Which of the following APGAR scores should the therapist expect to see for this
infant?
1. 4 then 8
2. 5 then 8
3. 6 then 10
4. 7 then 10
A. 1
B. 2
C. 3
D. 4 - ANSWERS: C. 3
The score for 1 minute is 6:
acrocyanosis = 1, heart rate of 70/min = 1, cough = 2, weak activity = 1,
respiratory rate of 20/min = 1.
The score for 5 minutes is 10:
pink = 2, heart rate of 110/min = 2, cough = 2, active motion = 2, respiratory rate
of 40/min = 2.
A 58-year-old female was diagnosed with bronchiectasis 3 years ago. She reports
increased cough and difficulty clearing secretions for the past 4 weeks. A chest
radiograph shows no significant changes. Which of the following should the
respiratory therapist recommend FIRST?
A. transtracheal aspiration
,3|Page
B. airway clearance therapy
C. bronchodilator treatments
D. respiratory isolation - ANSWERS: B airway clearance therapy
The history, clinical presentation, and chest radiograph findings suggest worsening
bronchiectasis. The treatment of bronchiectasis includes techniques to loosen and
mobilize viscid secretions. Postural drainage enhances sputum clearance.
A 24-year-old female is diagnosed with exercise-induced asthma and albuterol prn
is ordered. A respiratory therapist should NEXT
A. refer the patient for allergy skin testing.
B. educate the patient on obtaining daily peak flow measurements.
C. instruct the patient to use albuterol 15 minutes before exercising.
D. suggest the patient use pursed lip breathing while exercising. - ANSWERS: C.
instruct the patient to use albuterol 15 minutes before exercising.
Patient understanding of their disease process and triggers is important part of
patient education, as well as knowing when and which medication should be taken.
In which of the following circumstances will tracheal secretions tend to dry in an
intubated patient?
A. a water vapor pressure of 47 mm Hg
B. a relative humidity of 100% at 22° C (71.6° F)
C. a dew point of 37° C (98.6° F)
D. an absolute humidity of 44 mg/L - ANSWERS: B. a relative humidity of 100%
at 22° C (71.6° F)
The absolute humidity at this temperature is inadequate.

A dew point of 37° C (98.6° F) indicates the gas is completely saturated at that
temperature.
Prior to suctioning the endotracheal tube of an adult patient who is receiving
ventilation with an FIO2 of 0.40, a respiratory therapist should FIRST
A. lubricate the catheter.
B. hyperoxygenate the patient.
C. cleanse the catheter with water.
D. administer an FIO2 of 0.40 by T-piece. - ANSWERS: B. hyperoxygenate the
patient.
The FIO2 should be increased prior to each suctioning attempt to minimize
hypoxemia.
A 25-year-old patient with apnea is receiving PC ventilation. ABG analysis results
are as follows:
pH 7.20
PCO2 65 mm Hg
PO2 70 mm Hg
HCO3- 25 mEq/L
BE -4 mEq/L
SO2 (calc) 94%
A respiratory therapist should recommend increasing the?
A. set inspiratory pressure.
B. expiratory time.
C. sensitivity.
