Section 1: Airway, Respiration, and Ventilation (Questions 1-20)
1 A patient with a history of COPD presents with acute respiratory distress, pursed-lip breathing, and use of
accessory muscles. SpO2 is 88% on room air. Which of the following best explains the primary mechanism of
hypoxemia in this patient?
A) Alveolar hypoventilation leading to increased PaCO2 and decreased PAO2
B) Ventilation-perfusion mismatch due to destruction of alveolar walls and capillary beds
C) Right-to-left intrapulmonary shunt from atelectasis
D) Diffusion impairment due to thickened alveolar-capillary membrane
Answer: B
Rationale: In COPD, emphysematous changes cause destruction of alveolar septa and pulmonary capillaries, leading
to V/Q mismatch, which is the predominant cause of hypoxemia. Diffusion impairment (D) is less significant.
Shunt (C) and hypoventilation (A) are not primary mechanisms in COPD.
2 During a difficult intubation, a paramedic attempts a blind insertion of a supraglottic airway (SGA) in a patient
with a known esophageal varices. Which of the following is the most serious potential complication of this
maneuver in this patient?
A) Gastric insufflation and increased risk of regurgitation
B) Trauma to the varices leading to massive hemorrhage
C) Inability to achieve an adequate seal due to airway anatomy
D) Vagal stimulation causing bradycardia and hypotension
Answer: B
Rationale: Esophageal varices are fragile and prone to rupture. Blind insertion of an SGA can directly traumatize the
,varices, leading to life-threatening hemorrhage. While gastric insufflation is a known risk of SGA use, it is not the
most serious in this specific patient. Seal adequacy and vagal stimulation are less critical concerns.
3 A patient on a ventilator has the following capnography waveform: a gradual upward slope during expiration,
with an elevated baseline. The plateau phase is absent. Which of the following is the most likely cause?
A) Obstructive lung disease causing prolonged exhalation
B) Leak in the ventilator circuit
C) Rebreathing of CO2 due to exhausted CO2 absorbent
D) Patient triggering the ventilator during exhalation
Answer: C
Rationale: An elevated baseline (increased end-tidal CO2) with a gradual expiratory upslope and missing plateau
indicates rebreathing, typically from exhausted CO2 absorbent. Obstructive disease (A) shows a prolonged
expiratory phase but not an elevated baseline. A leak (B) would show decreased ETCO2. Patient triggering (D)
would cause waveform irregularities.
4 Which of the following correctly describes the effect of positive end-expiratory pressure (PEEP) on intracranial
pressure (ICP) in a patient with traumatic brain injury who is being mechanically ventilated?
A) PEEP increases ICP only if it causes a decrease in mean arterial pressure
B) PEEP consistently decreases ICP by improving venous drainage
C) PEEP increases ICP by impeding cerebral venous return
D) PEEP has no effect on ICP as long as PaCO2 is maintained
Answer: A
Rationale: PEEP can increase ICP by reducing cerebral venous return, but this effect is significant only when PEEP
causes a drop in MAP (decreasing cerebral perfusion pressure). If MAP is maintained, PEEP's effect on ICP is
minimal. Option C is oversimplified; the effect is conditional on hemodynamics.
5 A patient with a severe asthma exacerbation is being ventilated with a bag-valve mask (BVM) at a rate of 20
breaths per minute. After 2 minutes, the patient's blood pressure drops from 130/80 to 90/60. Which of the
following is the most likely cause?
A) Dynamic hyperinflation leading to decreased venous return
B) Hypovolemia from insensible fluid losses
C) Vasodilation from beta-agonist therapy
D) Tension pneumothorax from barotrauma
Answer: A
Rationale: In severe asthma, high expiratory resistance leads to air trapping (auto-PEEP). Rapid BVM ventilation
exacerbates this, increasing intrathoracic pressure and reducing venous return, causing hypotension. Tension
pneumothorax is possible but less likely without signs of unilateral breath sounds. Hypovolemia and vasodilation
are less acute.
6 Which of the following best explains why a patient with a large pulmonary embolism presents with hypoxemia
that is poorly responsive to high-flow oxygen?
A) Decreased cardiac output leading to low mixed venous oxygen content
B) Ventilation-perfusion mismatch due to bronchoconstriction
C) Intrapulmonary shunt from atelectasis
D) Diffusion impairment from pulmonary edema
Answer: A
Rationale: Massive PE causes acute right heart failure and decreased cardiac output. This results in low mixed
,venous oxygen content, which, when blood passes through non-ventilated areas (shunt physiology), exacerbates
hypoxemia. Oxygen therapy cannot correct shunt. V/Q mismatch (B) is present but not the primary driver of
refractory hypoxemia.
7 A paramedic is called to assist with a patient who has a tracheostomy tube in place and is in respiratory distress.
The patient is spontaneously breathing, but the SpO2 is 85% on 15 L/min via non-rebreather mask over the
stoma. Which of the following is the most appropriate initial intervention?
A) Replace the tracheostomy tube with a larger size
B) Suction the tracheostomy tube
C) Ventilate with a bag-valve mask connected to the tracheostomy tube
D) Apply a pediatric non-rebreather mask over the stoma
Answer: B
Rationale: Respiratory distress in a patient with a tracheostomy is often due to mucus plugging or obstruction.
Suctioning is the first step to clear the airway. Replacing the tube (A) is more invasive and not initial. Ventilating
(C) may be needed after suctioning if ineffective. The mask (D) is already in place with high flow.
8 Which of the following is the primary mechanism by which non-invasive positive pressure ventilation (NIPPV)
improves oxygenation in acute cardiogenic pulmonary edema?
A) Decreasing preload and afterload, reducing pulmonary congestion
B) Increasing functional residual capacity and recruiting collapsed alveoli
C) Directly reducing the permeability of the alveolar-capillary membrane
D) Increasing the partial pressure of oxygen in the alveoli
Answer: A
Rationale: NIPPV (CPAP/BiPAP) improves oxygenation primarily by reducing preload and afterload through
increased intrathoracic pressure, which decreases pulmonary edema. While alveolar recruitment (B) occurs, it is
secondary. NIPPV does not directly affect membrane permeability (C) or increase alveolar PO2 (D) beyond that of
supplemental oxygen.
9 A patient with a suspected opioid overdose is apneic and has a heart rate of 40 bpm. After administering
naloxone, the patient remains apneic. Which of the following is the most likely explanation?
A) The patient has concurrent brainstem stroke
B) The naloxone dose was insufficient to reverse the opioid effect
C) The patient has developed acute respiratory distress syndrome
D) The patient has a high degree of opioid tolerance
Answer: B
Rationale: Apnea despite naloxone in suspected overdose most commonly indicates inadequate dosing. Naloxone
has a short half-life and may need repeated doses. Brainstem stroke (A) is less likely without other neurological
signs. ARDS (C) does not cause apnea. Tolerance (D) would require higher doses, not explain failure to reverse.
10 A patient with a flail chest segment is in respiratory distress. Which of the following is the primary physiologic
abnormality that leads to hypoxemia in this condition?
A) Paradoxical movement of the flail segment causing ineffective ventilation
B) Pulmonary contusion underlying the flail segment causing intrapulmonary shunt
C) Pain from the fractures leading to splinting and hypoventilation
D) Loss of negative intrapleural pressure causing pneumothorax
Answer: B
Rationale: The primary cause of hypoxemia in flail chest is the associated pulmonary contusion, which leads to V/Q
, mismatch and shunt. Paradoxical movement (A) contributes to ventilatory inefficiency but is not the main cause of
hypoxemia. Pain (C) and pneumothorax (D) are secondary or less common.
11 A patient with chronic obstructive pulmonary disease (COPD) presents with acute respiratory distress. The
arterial blood gas (ABG) reveals pH 7.25, PaCO2 60 mmHg, PaO2 55 mmHg, HCO3- 26 mEq/L. After
initiating noninvasive positive pressure ventilation (NIPPV), which parameter best indicates adequate
ventilation?
A) PaO2 of 80 mmHg
B) PaCO2 of 40 mmHg
C) SpO2 of 92%
D) Minute ventilation of 6 L/min
Answer: B
Rationale: In COPD with acute on chronic respiratory failure, the goal of NIPPV is to improve alveolar ventilation,
reflected by a decrease in PaCO2 toward the patient's baseline (often elevated). A PaCO2 of 40 mmHg is too low
and may indicate overventilation; the patient's baseline PaCO2 is likely higher. PaO2 and SpO2 targets are
important but do not directly measure adequacy of ventilation. Minute ventilation is a raw value that does not
account for dead space or metabolic demand.
12 During a difficult airway scenario, a supraglottic airway device (SAD) is placed but ventilation remains
inadequate. Which of the following best explains why a SAD fails to provide adequate ventilation in this
context?
A) The device is incorrectly sized, causing a large leak
B) The patient has a high lung compliance, reducing delivered tidal volume
C) The device sits above the glottis and cannot bypass an obstruction at or below the vocal cords
D) The cuff pressure is too low, allowing gastric insufflation
Answer: C
Rationale: Supraglottic airway devices (e.g., LMA) sit above the glottis and provide a seal around the laryngeal
inlet. If the obstruction is at or below the vocal cords (e.g., laryngospasm, foreign body, tumor), the SAD cannot
bypass it, leading to inadequate ventilation. Incorrect sizing or low cuff pressure can cause leaks but are not the
fundamental limitation in this scenario. High lung compliance would actually improve ventilation, not hinder it.
13 A patient with suspected tension pneumothorax develops hypotension and distended neck veins after positive
pressure ventilation is initiated. Which hemodynamic change most directly explains the hypotension?
A) Decreased systemic vascular resistance due to vasodilation
B) Increased intrathoracic pressure reducing venous return
C) Myocardial depression from hypoxia
D) Pulmonary vasoconstriction causing right heart failure
Answer: B
Rationale: In tension pneumothorax, positive pressure ventilation exacerbates the condition by increasing
intrathoracic pressure further. This elevated pressure compresses the superior and inferior vena cava, reducing
venous return to the heart, which leads to decreased cardiac output and hypotension. While hypoxia and myocardial
depression may occur, the primary mechanism is impaired venous return. Systemic vasodilation is not a direct
effect of tension pneumothorax.
14 A patient is receiving volume-controlled ventilation at a rate of 12 breaths/min, tidal volume 500 mL,
inspiratory time 1 second, and PEEP 5 cm H2O. The flow-time waveform shows that expiratory flow does not
return to zero before the next inspiration. What adjustment is most appropriate to prevent breath stacking?
