100% PASS
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-Correct answer:
D. colorimetric capnography
Explanation:
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-Correct answer:
C. 6 at 1 min, 10 at 5 mins
Explanation:
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-Correct answer:
B. airway clearance therapy
Explanation:
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
