A 2 y/o child with croup has been intubated for 4 days with a
4mm ID uncuffed ETT. Heated aerosol at an FiO2 of 30% has
been delivered to the patient. The physician asks the RT to
evaluate the pt for possible extubation. Which of the following
would most likely indicate that the pt is ready for extubation?
A. Pt is making normal quiet ventilatory efforts
B. Negative sputum culture and sensitivity has been reported
C. Pt's ABG are within normal range
D. Breath sounds are heard around the tube on auscultation -
correct answer- D. Breath sounds are heard around the
tube on auscultation
A 19 y/o patient has a size 7 mm ID nasotracheal tube placed
through the right nare. While attempting to suction the patient
with a size 12 Fr catheter, resistance is met as the catheter is
introduced into the ETT. The RT should:
A. Lubricate the catheter with petroleum jelly prior to suctioning
,B. Instill acetylcysteine into the ETT
C. Switch to a 10 Fr suction catheter
D. Extubate the patient and reintubate with a size 9 mm ID ETT
- correct answer- C. Switch to a 10 Fr suction catheter
A 43 y/o female patient has just undergone a total abdominal
hysterectomy. The pt arrives in the post anesthesia care unit
obtunded with minimal response to painful stimulus. what
treatment should the RT recommend for this pt? - correct
answer- Insert OPA (b/c they are unresponsive)
A 58 y/o male patient is hypoxic on volume control ventilation
and is receiving 15 cm H20 of PEEP on an FiO2 0.60. Shortly after
increasing the PEEP therapy to 18 cm H20, the RT notes that the
systemic blood pressure has fallen from 110/72 mm Hg to 94/50
mm Hg and the cardiac output has fallen from 4.3 L/min to 2.5
L/min. The most appropriate action at this time would be to:
A. maintain the present therapy and re-evaluate the patient in
thirty minutes
B. decrease the PEEP to 15 cm H20 and increase the FiO2 to 0.70
C. decrease the PEEP to 12 cm H20 and maintain the FiO2 at
0.60
,D. discontinue the PEEP and increase the FiO2 to 0.80 -
correct answer- B. decrease the PEEP to 15 cm H20
and increase the FiO2 to 0.70
A 77 y/o male patient is admitted to the ER with shortness of
breath, fine basilar crackles, +2 pitting edema and a chest X-ray
with a butterfly pattern. These results are most consistent with
which of the following?
A. Pulmonary edema
B. Pulmonary interstitial emphysema
C. Pneumothorax
D. Emphysema - correct answer- A. Pulmonary edema
(and CHF!)
A 1600g neonate is receiving O2 by oxyhood at an FiO2 of 0.60.
the flowmeter is set at 5L/min. While analyzing the O2, the RT
notices varying FiO2 readings at a different locations inside the
oxyhood. Which of the following should the RT do to correct the
problem?
A. Re-calibrate the O2 analyzing device
B. Increase the flow to the oxyhood
, C. Place the neonate in an isolette at an FiO2 of 0.60
D. Check the water level of the humidifier - correct
answer- B. Increase the flow to the oxyhood
A balloon-tipped, flow directed catheter is positioned in the
pulmonary artery with the balloon DEFLATED. Which of the
following pressures will be measured by the DISTAL lumen? -
correct answer- PAP
A balloon-tipped, flow-directed catheter is positioned in the
pulmonary artery with the balloon inflated. Which of the
following pressures will be measured by the distal lumen?
A. CVP
B. PAP
C. PCWP
D. MAP - correct answer- PCWP
A change in airway resistance would be reflected by a change in
what? - correct answer- Dynamic Compliance
A change in airway resistance would be reflected by a change in:
A. dynamic compliance.
