1. A patient with acute hypoxemic respiratory
failure has a PaO2 of 52 mm Hg on an FiO2 of
0.60 via air-entrainment mask. The SpO2 is
86%. Breath sounds reveal bilateral coarse
crackles. Chest radiograph shows diffuse
bilateral infiltrates. Which condition is most
consistent with these findings?
A. COPD exacerbation
B. Acute respiratory distress syndrome
C. ARDS
,D. Status asthmaticus
E. Pulmonary embolism
ARDS presents with refractory hypoxemia,
bilateral infiltrates on chest radiograph, and
reduced lung compliance. The PaO2/FiO2 ratio
here is approximately 87, consistent with
severe ARDS.
2. A 70 kg patient is being ventilated in the
assist-control mode with a tidal volume of 500
mL, respiratory rate of 12 breaths/min, and
FiO2 of 0.50. ABG results show pH 7.32, PaCO2
50 mm Hg, PaO2 80 mm Hg, HCO3- 24 mEq/L.
Which change is most appropriate?
A. Decrease FiO2 to 0.40
B. Increase respiratory rate to 16 breaths/min
C. Increase tidal volume to 600 mL
D. Switch to pressure support ventilation
E. Add 5 cm H2O PEEP
The pH is acidotic with an elevated PaCO2
indicating hypoventilation. Increasing the rate
,will improve minute ventilation and normalize
pH and PaCO2.
3. During a spontaneous breathing trial, a
patient develops paradoxical abdominal
movement, accessory muscle use, and a
respiratory rate of 35 breaths/min. What should
the respiratory therapist recommend?
A. Extubate the patient
B. Return to mechanical ventilation
C. Administer a bronchodilator
D. Increase FiO2 to 1.0
E. Perform a recruitment maneuver
Paradoxical breathing, tachypnea, and
accessory muscle use indicate respiratory
muscle fatigue and failure of the SBT. The
patient should be returned to full ventilatory
support.
4. A patient receiving mechanical ventilation
has the following settings: SIMV rate 10, tidal
volume 500 mL, FiO2 0.45, PEEP 5 cm H2O. The
, patient is triggering spontaneous breaths at a
rate of 8 breaths/min with an average tidal
volume of 180 mL. What is the most likely cause
of the low spontaneous tidal volume?
A. Excessive PEEP
B. Inadequate pressure support
C. Low FiO2
D. Kinked endotracheal tube
E. Ventilator malfunction
Without adequate pressure support,
spontaneous breaths through the narrow ETT
and circuit result in low tidal volumes and
increased work of breathing.
5. A 55-year-old patient post-abdominal surgery
has an SpO2 of 91% on room air. The patient is
alert with a respiratory rate of 22 breaths/min.
Which oxygen delivery device would be most
appropriate to achieve an SpO2 of 94%?
A. Nonrebreathing mask at 10 L/min
B. Nasal cannula at 3 L/min
