CRT Practice Questions
A patient is admitted to the ED following a vehicle accident. On physical exam, the RT
discovers that breath sounds are absent in the left chest with a hyper resonant
percussion note. The trachea is shifted to the right. The patient's heart rate is 45/min,
RR is 30/min and BP is 60/40 mmHg. What action should the therapist reccomend first?
-
\Needle aspirate the 2nd left intercostal space
A 65kg spinal cord injured patient has developed atelectasis. His inspiratory capacity is
30% of his predicted value. What bronchial hygiene therapy would be most appropriate
initially? -
\IPPB with normal saline
A healthy adult female can exhale what portion of her forced vital capacity in the first
second? -
\70%
A patient on VC ventilation has demonstrated auto-PEEP on ventilator graphics. Which
of the following controls, when adjusted independently, would increase expiratory time?
-
\Tidal volume, Respiratory Rate and Inspiratory flow
A 55 y/o post cardiac surgery patient has the following ABG results: pH 7.50, PaCO2 30
torr, PaO2 62 torr, HCO3 25 mEq/L, SaO2 92%, HB 14 g;dL, BE +2. Venous blood gas
results are pH 7.39, PvCO2 43 torr, PvO2 37 torr, and SvO2 66%. Calculate the
patient's C(a-v)O2. -
\4.0 vol%
TO SOLVE:
- Use formula: C(a-v)O2 = CaO2 - CvO2
- CaO2 = (Hb x 1.34 x SaO2) + (PaO2 x 0.003)
**Normal amounts are 4-5%
Immediately after extubation of a patient in the ICU, the RT observes increasing
respiratory distress with intercostal retractions and marked stridor. The SpO2 on 40%
O2 is noted to be 86%. What would be the most appropriate response at this time? -
\Reintubation (due to marked stridor)
What may be obtained from a FVC maneuver during beside PFTs? -
\FEV1 and PEFR
, What suction catheter would be appropriate for a patient with a size 8.0mm ID ETT? -
\12 Fr
- Use formula ID size/2 X 3
The RT notes a developing hematoma after and ABG was drawn from the right radial
artery. The immediate response is to: -
\apply pressure to the site
A patient on the general medical ward is on a 28% air entrainment mask with the
flowmeter set at 5L/min. What is the total flow delivered to the patient? -
\55L/min
TO SOLVE
- 28% --> 10:1 ratio --> 11 total flow factor
- Total flow factor x set values for L/min (so 5L/min x 11 = 55L/min)
What measurement is most indicative of pulmonary edema?
- HR 120/min
- BP of 92/72 mmHg
- Pulmonary artery pressure of 25/10 mmHg
- Pulmonary Capillary Wedge Pressure of 30mmHg -
\Pulmonary capillary wedge pressure of 30mmHg (normal range = 4-12mmHg)
Sleep apnea can be defined as repeated episodes of complete cessation of airflow for: -
\10 seconds or longer
A patient in the ICU receiving mechanical ventilation has just undergone a fiberoptic
bronchoscopy procedure in withh a tissue biopsy was collected. Immediately following
the procedure, the RT notes that the peak inspiratory pressure on the ventilator has
increased. Potential causes for this include: -
\Pneumothorax, pulmonary hemorrhage, bronchospasm/laryngospasm
NOT hypoxemia
A patient who suffered trauma in an ATV accident is being monitored in the ICU. A
pulmonary artery catheter has been placed and the following data is available:
- PvO2 46 torr
- PCWP 19mm Hg
- PAP (mean) 10mm Hg
- CVP 12cm H20
- Qt 3L/min
What should the RT recommend? -
