A respiratory therapist is assisting a physician during a transtracheal bronchoscopy. As the
bronchoscope is advanced in the airways, the above ECG tracing is observed on the patient's
cardiac monitor. The RT should recommend? - answers-Administration of lidocaine.
After extubating a patient the RT observes the onset of inspiratory stridor. After administering
racemic epinephrine (vaponefrin), the patient still has inspiratory stridor, but a lesser extent.
The therapist should now do what? - answers-Continue with current therapy.
Prior to bronchodilator therapy, a patient is tachycardic and tachypneic with bilateral
inspiratory and expiratory wheezing. 30 minutes after the administration of the bronchodilator,
the patient has normal vital signs and is resting comfortably. Which of the following has most
clearly improved? - answers-Resistance to airflow
While monitoring a patient during a traditional t tube weaning trial with an FiO2 of 0.40. the
respiratory therapist records the following data:
-------------------------------------
Data prior to weaning 15 minutes after the start of weaning
Heart Rate
88/min 112/min
Respiratory Rate
12/min 24/min
PaCO2
37 mm Hg 54 mm Hg
1
,PaO2
79 mm Hg 72 mm Hg
Which of the following actions would be appropriate at this time? - answers-Reconnect the
patient to the ventilator with prior settings.
If the flowmeter is set too low on high flow oxygen system, the RT should expect - answers-A
decrease in inspired oxygen
After a patient is placed in the head down position for postural drainage of the right lower lobe,
he begins to cough vigorously and becomes short of breath. What should the RT do? - answers-
Sit patient up and reassure him coughing is normal.
Which of the following is best suitable for an adult patient requiring long-term continuous
ventilatory support? - answers-A cuffed tracheostomy tube
Nasotracheal intubation would be preferred over oratracheal intubation in which of the
following clinical situations? - answers-4; Repair of a fractured mandible-yes/no/no
The most important aspect regarding quality control for blood gas analyst is that? - answers-The
blood gas analyzer always functions properly prior to patient sample analysis
When using a non rebreathing oxygen mask, the flowmeter should be set on? - answers-Where
the bag does not deflate more than one third during inspiration
An ICU patient has been receiving potassium replacement therapy for two days. The ECG
rhythm shown above was recorded on the patients cardiac monitor on day 2 treatment. Which
of the following should the RT initially recommend to further assess the patients clinical
2
, conditions? - answers-Electrolytes
A RT is caring for a neonatal patient who has a transcutaneous PO2 electrode in place on the
right chest. Over the last 6 hrs, the therapist observes that the transcutaneous PO2
measurement has decreased from 79 mm Hg to 62 mm Hg. The most likely cause for this
situation is - answers-The neonates pulmonary condition has deteriorated
After being asked to take a breath , the patient states that he is unable to take a deep breath.
The RT would conclude that the patient is most likely: - answers-Uncooperative
A 52 yr old obese male in acute respiratory distress has just been admitted to the ED. Physical
examination reveals accessory ventilatory muscle use, neck vein distension, and pedal edema.
There is markedly diminished breath sounds and expiratory wheezes throughout both lung
fields. The patient is expectorating copious mucopurulent sputum. The patients vital signs are:
pulse 132/min, BP 196/112 mm Hg; respirations 38/min, and temperature 100.1 deg F. ABG's
drawn while the patient was breathing room air are: ph:7.27, PaO2:54 mm Hg, PaCO2: 62 mm
Hg, HCO3: 27. Which of the following is the most likely diagnosis for this patient ? - answers-
Chronic bronchitis exacerbated by an acute pulmonary infection
The data shows for an intubated , Mechanically ventilated patient receiving an FiO2 of 0.90 -
Cardiac output- 5.9 L/min
- Blood pressure- 132/86 mmHg
- Ph- 7.38
- PaCO2- 42 mm Hg
- HCO3- 24
- PaO2- 61 mm Hg
The data are suggestive for which of the following? - answers-Adult respiratory distress
syndrome
The second heart sound ( S2 ) is produced by? - answers-The sudden closing of the aortic and
3
