SECTION ONE: QUESTIONS 1–50
════════════════════════════════════
1. A 68-year-old male with a history of COPD presents with worsening dyspnea,
a productive cough with purulent sputum, and increased use of accessory
muscles. Arterial blood gas (ABG) results on room air show: pH 7.31, PaCO2 68
mmHg, PaO2 55 mmHg, HCO3- 34 mEq/L. Which of the following is the most
likely interpretation of these ABG results?
A. Acute respiratory acidosis with no metabolic compensation
B. Partially compensated chronic respiratory acidosis
C. Compensated metabolic alkalosis
D. Acute respiratory acidosis with metabolic acidosis
🟢 Correct Answer: B. Partially compensated chronic respiratory acidosis
🔴 Explanation: The pH is acidic (7.31), PaCO2 is elevated (68 mmHg) indicating
respiratory acidosis. The HCO3- is elevated (34 mEq/L), which is high for the
baseline but insufficient to bring the pH to normal, indicating incomplete or
partial compensation. The high HCO3- suggests a chronic component, as renal
compensation takes 3-5 days to develop. This is a classic presentation of an acute
exacerbation of chronic COPD.
2. You are setting up a non-invasive positive pressure ventilation (NPPV) mask
for a patient with acute exacerbation of COPD. Which of the following initial
settings is most appropriate?
A. IPAP 8 cm H2O, EPAP 4 cm H2O
B. IPAP 12 cm H2O, EPAP 4 cm H2O
C. IPAP 4 cm H2O, EPAP 12 cm H2O
D. IPAP 10 cm H2O, EPAP 10 cm H2O
,🟢 Correct Answer: B. IPAP 12 cm H2O, EPAP 4 cm H2O
🔴 Explanation: For an acute COPD exacerbation, typical initial settings for NPPV
are an IPAP of 10-12 cm H2O and an EPAP of 4-5 cm H2O. This provides adequate
pressure support to unload the respiratory muscles and improve ventilation, while
a lower EPAP helps to prevent dynamic hyperinflation and auto-PEEP. Option A
provides insufficient inspiratory support, while options C and D are not
appropriate initial settings for this scenario.
3. A patient is being mechanically ventilated in the SIMV mode with a rate of 14
breaths/min, tidal volume of 600 mL, and FiO2 of 0.50. The peak inspiratory
pressure (PIP) is 45 cm H2O, and the plateau pressure (Pplat) is 30 cm H2O.
What is the approximate static compliance of the respiratory system?
A. 10 mL/cm H2O
B. 20 mL/cm H2O
C. 30 mL/cm H2O
D. 40 mL/cm H2O
🟢 Correct Answer: B. 20 mL/cm H2O
🔴 Explanation: Static compliance is calculated as Tidal Volume / (Plateau
Pressure - PEEP). Assuming a PEEP of 0 cm H2O in this scenario, the calculation is
600 mL / 30 cm H2O = 20 mL/cm H2O. This value indicates poor compliance,
which can be seen in conditions like ARDS, pulmonary fibrosis, or pulmonary
edema. The PIP is used to calculate airway resistance, not compliance.
4. Which of the following pathogens is most commonly associated with
ventilator-associated pneumonia (VAP) in the early onset phase (within the first
4 days of hospitalization)?
A. Pseudomonas aeruginosa
B. Acinetobacter baumannii
, C. Streptococcus pneumoniae
D. Stenotrophomonas maltophilia
🟢 Correct Answer: C. Streptococcus pneumoniae
🔴 Explanation: Early-onset VAP (within 4 days of hospitalization) is typically
caused by community-acquired pathogens such as Streptococcus pneumoniae,
Haemophilus influenzae, and methicillin-sensitive Staphylococcus aureus (MSSA).
Multi-drug resistant (MDR) organisms like Pseudomonas aeruginosa,
Acinetobacter, and Stenotrophomonas are more commonly associated with late-
onset VAP (after 4 days) or in patients with prior antibiotic exposure or
healthcare-associated risk factors.
5. A patient's pulse oximeter reads 90% saturation on room air. The patient is
receiving supplemental oxygen via a nasal cannula at 2 L/min. Which of the
following is an appropriate therapeutic goal for this patient?
A. Increase the FiO2 to achieve a SpO2 of 100%
B. Maintain an SpO2 target of 88-92% if at risk for hypercapnia
C. Decrease the oxygen flow to 1 L/min to avoid oxygen toxicity
D. Wean the patient to room air immediately
🟢 Correct Answer: B. Maintain an SpO2 target of 88-92% if at risk for
hypercapnia
🔴 Explanation: For patients at risk for hypercapnic respiratory failure (e.g.,
COPD), the therapeutic target for SpO2 is often 88-92%. This is to avoid
suppression of the hypoxic drive, which can lead to increased CO2 retention and
acidosis. A target of 100% is not necessary and could be harmful. Decreasing the
flow when the patient is at 90% on 2 L/min may lead to further desaturation and
is not advisable.
