A 31-year-old male is intubated after a motor vehicle crash. A respiratory therapist palpates
asymmetrical chest movement during each inspiration when the manual resuscitator is
squeezed, but no crepitus. Breath sounds are diminished on the left. Which of the following
should the therapist do FIRST?
A.Perform colorimetric capnometry.
B.Administer a bronchodilator.
C.Obtain an arterial blood gas sample.
D.Assess depth of endotracheal tube insertion.

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 5 minutes
Appearance acrocyanosis pink
Heart rate 70/min 110/min
Reflexcough cough
,Muscle tone weak active motion
Respiratory rate 20/min 40/min
Which of the following APGAR scores should the therapist expect to see for this infant?
1-minute 5-minute
1. 4 8
2. 5 8
3. 6 10
4. 7 10
A.1
B.2
C.3
D.4
C.3√
The APGAR scoring system consists of the following:
Score 012Appearance pale or blue acrocyanosis completely pinkHeart rate absent < 100 per
minute > 100 per minuteReflex no response grimace cry, cough, sneezeMuscle tone limp some
flexion active motionRespiratory rate absent slow, irregular good cry
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
B.airway clearance therapy
C.bronchodilator treatments
D.respiratory isolation
B.√airway clearance therapy
RATIONALS : B. 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 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.
D.peak flow.
A.√set inspiratory pressure.
, RATIONALS : A. In PC ventilation, increasing the inspiratory pressure will result in an increased
tidal volume and minute ventilation, potentially causing a decrease in the PCO2.
A pulse oximeter can provide an accurate indication of a patient's oxyhemoglobin saturation in
which of the following clinical conditions?
1. congestive heart failure
2. polycythemia
3. pulmonary hypertension
4. carbon monoxide poisoning
A.1, 2, and 3 only
B.2, 3, and 4 only
C.1, 2, and 4 only
D.1, 3, and 4 only
A.√1, 2, and 3 only
RATIONALS : A. Carbon monoxide poisoning will result in carboxyhemoglobin. Standard pulse
oximetry is unable to distinguish oxyhemoglobin from carboxyhemoglobin, which will lead to a
falsely elevated SpO2 reading.
Mechanical ventilation was initiated for a patient, after which the PaCO2 decreased from 53 to
40 mm Hg. A respiratory therapist should expect which of the following will increase?
