A 13 y/o patient in the ED is complaining of dyspnea, chest tightness, and a loose
productive cough. The patient has a RR of 28 bpm, and a bilateral wheezing in the
lungs. What treatment should the RT initiate? - CORRECT ANSWER: Oxygen!
A 44 y/o patient who suffered a cerebral vascular accident has been moved from Neuro-
ICU to the step-down unit. He becomes diaphoretic and his SpO2 suddenly drops from
95% to 88% on a 32% tracheostomy collar. His HR is 115/min, RR is 42/min and his
breath sounds are very diminished. The RT is unsuccessful in attempting to pass a 12
Fr suction catheter. The RT should: - CORRECT ANSWER: Replace the tracheostomy
tube
A 50 kg (110 lb) patient is being mechanically ventilation with the following settings: VC
A/C, VT 400 mL, RR 14/min, FiO2 60%, and 10cm H20 PEEP. The chest radiograph
demonstrates diffuse bilateral radiopacity.
What should the RT increase? - CORRECT ANSWER: PEEP (b/c it helps with
oxygenation); DON'T touch CO2 since they are compensated!
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. - CORRECT ANSWER: 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%
A 60 kg (132 lb) patient is being mechanically ventilated wit hthe following settings: VC,
A/C; VT 500 mL, RR 12/min, FiO2 100% and 10 cm H20 PEEP. The patient's PIP is
60cm H20 and his SpO2 is 85%. A current chest x-ray shows diffuse bilateral infiltrates.
Which of the following is the most appropriate action in order to reduce PIP? -
CORRECT ANSWER: Change to airway pressure release ventilation (in considering of
ARDS, high airway pressures)
A 65 y/o female patient with advanced emphysema comes to the ED and is placed on a
nasal cannula at 6 L/min. On inspection, the RT finds that the patient has become
drowsy and less responsive since the O2 therapy was initiated an hour ago. ABG on 6
L/min are: pH 7.33, PaCO2 64 torr, PaO2 85 torr, and HCO3 35 mEq/L. What should
the RT recommend? - CORRECT ANSWER: Change to 24% Venti-mask and repeat
ABG
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? - CORRECT ANSWER: IPPB with normal saline
A 68 y/o patient with advanced emphysema is receiving oxygen by nasal cannula at 1
L/min. The physician has ordered that the patient's SpO2 be maintained at 90%. ABG
on 1 L/min are pH 7.34, PaCo2 65 torr, PaO2 55 torr, HCO3 35 mEq/L. What should the
RT do first? - CORRECT ANSWER: Titrate oxygen flow to the nasal cannula (turn up!)
A 70 kg (154 lb) patient with emphysema is receiving mechanical ventilation. Current
ventilator settings are as follows: VC, SIMV; VT 550mL; RR 12/min; FIO2 30%. The
patient is awake and alert and does not appear to be in any distress. The total RR is
14/min. ABG results are as follows: pH 7.35, PaCo2 58 torr, PaO2 65 torr, HCO3 30
mEq/L. His SpO2 is 94% and MIP is -30 cm H20. The patient is most likely: -
CORRECT ANSWER: Ready for a spontaneous breathing trial (because he's
compensated!)
