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 ETT
B. observable condensation in the tube
C. pulse oximetry
D. colorimetric capnography
Correct answer:
D. colorimetric capnography
RATIONALS:
A. the cm mark of the ETT is an indicator of depth of insertion, but does not confirm placement
in the trachea
B. condensation is often associated with intubation, but is not confirmation of correct
placement.
C. pulse ox is an assessment of oxygenation and does not provide confirmation of tracheal
placement
,D. colorimetric capnography assesses the presence of CO2 and provides confirmation of
tracheal intubation due to detection of CO2
A respiratory therapist is asked to review a newborn's history. The following information is
available about the first few minutes after birth:
After 1 minute: appearance is acrocyanotic, heart rate is 70 b/m, reflexes include cough, muscle
tone is weak, and RR is 20 br/m.
After 5 minutes: appearance is pink, heart rate is 110 b/m, reflexes include cough, muscle tone
shows active motion, and RR is 40 br/m
Which of the following APGAR scores should the therapist expect to see for this infant?
A. 4 at 1 min, 8 at 5 mins
B. 5 at 1 min, 8 at 5 mins
C. 6 at 1 min, 10 at 5 mins
D. 7 at 1 min, 10 at 5 mins
Correct answer:
C. 6 at 1 min, 10 at 5 mins
RATIONALS:
APGAR = appearance (color), pulse (HR), grimace (reflex/irritability), activity (muscle tone), and
respirations
According to the scoring chart, the score for 1 minute is acrocyanosis (1) + low HR (1) + cough
(2) + weak activity (1), and low RR (1) = 6
,According to the scoring chart, the score for 5 minutes is pink (2), normal HR (2), cough (2),
active motion (2), and normal RR (2) = 10
A 58-year-old female was dx with bronchiectasis 3 years ago. She reports increased cough and
difficulty clearing secretions for the past 4 weeks. A CXR shows no significant changes. Which of
the following should the RT recommend FIRST?
A. transtracheal aspiration
B. airway clearance therapy
C. bronchodilator treatments
D. respiratory isolation
Correct answer:
B. airway clearance therapy
RATIONALS:
A. while a sputum sample may be requested, transtracheal aspiration would be unnecessarily
invasive as the patient is able to produce a sputum sample on her own
B the hx, clinical presentation, and CXR findings suggest worsening bronchiectasis. The tx of
bronchiectasis includes techniques to loosen and mobilize viscid secretions. Postural drainage
enhances sputum clearance.
C. bronchodilator therapy alone will not aid in secretion removal
D. there is no indication of this patient having a communicable disease. The dx of bronchiectasis
was established 3 years ago
A 24-year-old female is dx with exercise-induced asthma and albuterol prn is ordered. A RT
should NEXT:
, A. refer the pt for allergy skin testing
B. educate the pt on obtaining daily peak flow measurements
C. instruct the pt to use albuterol 15 mins before exercising
D. suggest that the pt use pursed lip breathing while exercising
Correct answer:
C. instruct the patient to use albuterol 15 mins before exercising
RATIONALS:
A. allergy skin testing is not a routine part of EIA management
B. daily peak flow measurements will not be helpful for EIA
C. patient understanding of their disease process and triggers is important part of pt education,
as well as knowing when and which medication should be taken and how to take it
D. pursed lip breathing is not helpful for EIA
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 22C (71.6F)
C. a dew point of 37C (98.6F)
D. an absolute humidity of 44 mg/L
Correct answer:
B. a relative humidity of 100% at 22C (71.6F)
