A 47-year-old male with a BMI of 50 kg/m is undergoing a sleep study with
titration of CPAP. The patient's baseline AHI is 59. At a CPAP level of 7 cm H20, the
AHI is 9. A respiratory therapist should recommend
a. Maintain the current level of CPAP
b. Decreasing the CPAP
c. Increasing the CPAP
d. Changing to bilevel PAP
Increasing the CPAP
Explain: The goal of CPAP intervention is to completely eliminate apnea and
hypopnea episodes, standard protocol is to incrementally increase the CPAP
level until this occurs.
An arterial puncture has been performed to obtain blood for analysis of 02, C02,
and pH. What is the best way to manage the blood sample?
a. Warm the sample to keep it at body temperature
b. Place it into a mix of ice and water
c. Let the blood naturally cool to room temperature
d. Shake the sample to hemolyze the blood
Place it into a mix of ice and water
Explain: Placing the blood sample into ice water will prevent the blood from
consuming the O2 within the sample.
A 26-year-old patient who weighs 80 kg (171 lb) received injuries in a motor
vehicle crash. The patient was intubated with a 6.0-mm ID endotracheal tube and

is receiving volume-controlled ventilation. Twenty-four hours later, the patient has
clear breath sounds but cannot tolerate weaning the mandatory rate below 8 in
the SIMV mode with 15 cm H20 pressure support. The respiratory therapist
should recommend.
a. Increasing the peak inspiratory flow
b. Raising the VT
c. Setting the mandatory rate to 10
d. Reintubating with a larger endotracheal tube
Reintubating with a larger endotracheal tube
Explain: The small endotracheal tube compromises spontaneous breathing
because of increased airways resistance. This can be resolved only by a larger
tube or extubation.
During nasotracheal suctioning, a patient exhibits a gag reflex but doesn't cough.
Watery secretions are aspirated through the catheter. Which of the following
should the respiratory therapist do next?
a. Insert an oropharyngeal airway and repeat the procedure
b. Hyperextend the patient's next when passing the catheter
c. Ask the patient to swallow while passing the catheter
d. Increase the suction pressure and repeat the procedure
Hyperextend the patient's next when passing the catheter
Explain: Aspiration of watery secretions would indicate catheter position in
either the oropharynx or the esophagus. Hyperextending the neck will better
direct the catheter to the trachea.
A 24-year-old female presents with a history of nasal stuffiness, episodes of
daytime dyspnea, and a cough that occurs every summer. Which of the following
drug classifications should a respiratory therapist recommend to control the
patient's symptoms?

a. Leukotriene inhibitor
b. IgE immunoglobulin antagonist
c. Beta-adrenergic agonist
d. Anticholinergic
Leukotriene inhibitor
Explain: The patient has allergic rhinitis and, at most, mild persistent asthma. A
leukotriene inhibitor, such as montelukast (Singulair), are indicated to control
mild asthma and allergic rhinitis.
A patient with pulmonary edema receives furosemide (Lasix), dopamine
(Intropin), and 02. Flattened T-waves and occasional PVC's are observed on the
monitor. Which of the following should a respiratory therapist initially recommend
to evaluate the effect of these medications?
1. End-tidal C02
2. Pulse oximetry
3. Echocardiogram
4. Electrolytes
Choose the best answer
a. 1 and 2 only
b. 1 and 3 only
c. 2 and 4 only
d. 3 and 4 only
2 and 4 only
Explain:
1. False. End-tidal CO2 would not be related to diuresis, electrolyte imbalance,
or hypoxemia.
2. True. Myocardial hypoxia may contribute to cardiac arrythmia.

3. False. An echocardiogram may document the heart failure but does not relate
to the consequences of diuresis.
4. True. Electrolytes will help evaluate any changes associated with renal
potassium loss from the use of furosemide (Lasix).
When instructing a patient on the administration of umeclidinium/vilanterol
(Anoro Ellipta), Which of the following is most important to emphasize?
a. Gargle immediately after use
b. Inhale slowly with a breath hold
c. Breathe in fast and deep
d. Shake medication vigorously before use
Breathe in fast and deep
Explain: Breathing in fast and deep is the proper method of administration for
umeclidinium/vilanterol (Anoro Ellipta).
Before a respiratory therapist gives a new patient a breathing treatment with
formoterol (Perforomist), his vital signs are checked. The patient's initial HR is 85
bpm, and RR is 16 bpm. Halfway into the treatment, his pulse rate (HR) is 115
bpm, and the RR is 22 bpm. What should be done?
a. Continue the treatment to completion and recheck vital signs
b. Substitute Olodaterol (Stiverdi Respimat) and continue the treatment
c. Stop the treatment and monitor the patient
d. Stop the treatment and have the nurse give medication intravenously
Stop the treatment and monitor the patient
Explain: It is best to stop the treatment because the patient's vital signs have
increased by more than 20%. Inform the physician or nurse of the changes in
vital signs and chart the information.
