1. An infant with pneumonia is placed on CPAP with the initial level is 6 cm
H20. After the patient is placed on the system, the respiratory therapist
notices that the pressure falls to 2 cm H20 with each inspiration. What should
be done to correct the problem?
a. Tell the patient to relax and breath more slowly
b. Give the patient diazepam (Valium)
c. Increase the CPAP level to 8 cm H20
d. Increase the flow through the system: Increase the flow through the
system
Explain: Decreasing pressure with inspiration indicates inadequate gas flow.
Increasing the flow should meet the patient's inspiratory flow needs and
stabilize the CPAP pressure.
2. A respiratory therapist is called to the ED for a 1-year-old with difficulty
breathing. Severe suprasternal, subcostal and substernal retraction are
observed. The child has a harsh, barking cough. Stridor is present. The
therapist should anticipate treatment for Choose only ONE best answer.
a. Cystic Fibrosis
b. Pneumonia
c. Croup
d. Asthma: Croup
,Explain: The patient has some degree of upper airway obstruction caused by
some viral illness. The barky cough is a classic finding for patients
experiencing croup.
3. The polysomnography sleep laboratory is full scheduled for several weeks.
The physician wants to know if there is another option to determine if a
patient has sleep apnea. What should be recommended? a. Overnight pulse
oximetry
b. Nasal air flow monitoring
c. Holter monitoring for 48 hours
d. Chest-wall and abdominal-wall impedance comparison: Overnight pulse
oximetry Explain: Overnight pulse oximetry can be used to screen
patients with suspected obstructive sleep apnea. The patient's oxygen
saturation is found to decrease during apnea episodes.
4. A respiratory therapist is assessing a 168-cm (5-ft 6-in), 73-kg (161-lb), a
41-year-old female who was admitted 12 hours ago for an aspirin overdose.
The following information is obtained as the patient breathes air:
HR 89/min
RR 15/min
BP 110/70 mm Hg
Sp02 86%
A respiratory therapist should do first.
a. Initiate oxygen at 4L/min by cannula
b. Record the results in the medical record
c. Obtain an arterial blood gas sample
d. Validate the Sp02 reading at a different site: Validate the Sp02 reading at
a different site
Explain: The saturation may not be accurate and should be measured at a
different site.
,5. 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.
6. 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.
7. 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.
8. 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.
9. 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
