QUESTIONS |GRADED A+
SECTION 1: AIRWAY, RESPIRATION, & VENTILATION (Q 1-30)
Q1. You are managing a 68-year-old male with severe COPD exacerbation. He is
conscious but confused, with a respiratory rate of 8/min and SpO2 of 82% on
room air. According to SNHD 2026 protocols, what is the MOST appropriate initial
airway intervention?
A) Nasopharyngeal airway (NPA) with high-flow nasal cannula at 15 L/min
B) Supraglottic airway (SGA) insertion with BVM ventilations
C) Basic airway maneuvers (head-tilt/chin-lift) and BVM ventilations with 100% O2
D) Immediate orotracheal intubation utilizing RSI
Answer: C
Rationale: SNHD protocols mandate that basic airway maneuvers and BVM
ventilation are the first-line interventions for any patient with severe
hypoventilation (rate of 8/min) or apnea, regardless of etiology. Option A (NPA +
HFNC) is inadequate because a rate of 8/min requires positive-pressure
ventilation, not just supplemental oxygen. Option B (SGA insertion) is an
advanced airway that should only be placed after basic maneuvers have failed or
if BVM ventilation is ineffective. Option D (RSI intubation) is outside the AEMT
scope and requires an ALS provider; it is also unnecessary if BVM can support the
patient. Therefore, initiating BVM with 100% O2 while maintaining a patent
airway with head-tilt/chin-lift (or jaw-thrust if trauma is suspected) is the correct,
protocol-driven action.
Q2. A 45-year-old asthmatic is in severe respiratory distress. You auscultate
diminished breath sounds and wheezing. You apply a CPAP device. What is the
INITIAL pressure setting recommended by SNHD for a patient with acute
bronchospasm?
A) 5 cm H2O
B) 10 cm H2O
C) 15 cm H2O
D) 20 cm H2O
1
,Answer: B
Rationale: SNHD's CPAP protocol for respiratory distress (asthma or CHF) specifies
an initial pressure of 10 cm H2O. This pressure is sufficient to splint alveoli open
and reduce work of breathing without causing significant hemodynamic
compromise or patient intolerance. Option A (5 cm H2O) is too low to provide
meaningful alveolar recruitment in acute bronchospasm. Option C (15 cm H2O) is
the maximum pressure to which you may titrate if the patient does not improve
at 10 cm H2O, but it is not the starting point. Option D (20 cm H2O) exceeds the
protocol's upper limit and risks gastric insufflation and pneumothorax. Always
start low and titrate upward based on clinical response and SpO2.
Q3. You are ventilating an apneic adult with a BVM and an oropharyngeal airway.
You are unable to achieve chest rise despite repositioning the airway. What is
your NEXT action per SNHD guidelines?
A) Increase the ventilation pressure to 60 cmH2O
B) Immediately perform a surgical cricothyrotomy
C) Use a two-person BVM technique with an oral airway in place
D) Insert an i-gel supraglottic airway
Answer: C
Rationale: When a single rescuer cannot achieve chest rise with a BVM, the next
step per SNHD is the two-person BVM technique—one rescuer uses both hands to
maintain a tight mask seal while the other squeezes the bag. This maximizes tidal
volume delivery and often resolves the problem. Option A (increasing pressure to
60 cmH2O) is dangerous and can cause gastric rupture or barotrauma. Option B
(surgical cricothyrotomy) is a rescue procedure reserved exclusively for the "can't
ventilate, can't oxygenate" scenario after all other airway maneuvers have failed.
Option D (SGA insertion) is appropriate only if BVM ventilation remains ineffective
after two-person technique; it is not the immediate next step. Always escalate
systematically.
Q4. Which of the following is a CONTRAINDICATION for the use of a
Nasopharyngeal Airway (NPA) in a trauma patient?
A) GCS of 8
2
,B) Suspected basilar skull fracture
C) Apnea
D) Severe facial fractures
Answer: B
Rationale: SNHD protocols caution against NPA insertion when a basilar skull
fracture is suspected (signs include raccoon eyes, Battle's sign, CSF
otorrhea/rhinorrhea) due to the rare but catastrophic risk of intracranial
placement of the tube through a fractured cribriform plate. Option A (GCS of 8) is
an indication for an NPA (or OPA) because the patient cannot protect their
airway. Option C (apnea) requires ventilation; an NPA alone is not a
contraindication—it helps maintain patency. Option D (severe facial fractures) is a
contraindication for an OPA (which requires mouth opening), not an NPA; in fact,
NPA is often preferred in facial fractures when the mouth cannot be opened.
Remember: NPA = nasal, basilar skull fracture = NO.
Q5. You are called for a 6-month-old infant with bronchiolitis. The infant has
audible stridor and retractions. SpO2 is 88%. What is the preferred method for
maintaining a patent airway and delivering oxygen in this pediatric patient per
SNHD?
A) Oropharyngeal airway (OPA) sized correctly
B) Nasopharyngeal airway (NPA) with blow-by oxygen
C) CPAP at 5 cmH2O
D) Suctioning with a rigid Yankauer tip
Answer: B
Rationale: Infants are obligate nasal breathers, so an NPA is highly effective in
bypassing nasal congestion and maintaining a patent airway while allowing blow-
by oxygen delivery without causing distress. Option A (OPA) is often poorly
tolerated in a conscious infant and can stimulate gagging or vomiting. Option C
(CPAP at 5 cmH2O) is not a first-line SNHD treatment for bronchiolitis without a
physician order; it is reserved for severe respiratory failure with hypoxia
refractory to standard therapy. Option D (rigid Yankauer suction) is used for
visible secretions, not as a primary airway adjunct. The NPA is sized by measuring
from the nares to the tragus of the ear.

, Q6. Your partner is performing BVM ventilations on an adult. You notice gastric
insufflation is occurring. What adjustment should you make to minimize this?
A) Increase the tidal volume
B) Decrease the rate of ventilation
C) Increase the peak inspiratory pressure
D) Apply cricoid pressure (Sellick maneuver)
Answer: B
Rationale: Gastric insufflation occurs when high peak airway pressures force air
into the stomach. The most effective way to reduce this is to decrease the
ventilation rate, which allows more time for exhalation and reduces the pressure
generated with each breath. Option A (increase tidal volume) would worsen
insufflation by raising pressures. Option C (increase peak pressure) is
contraindicated for the same reason. Option D (cricoid pressure) is no longer
routinely recommended by AHA/SNHD for BVM because it does not reliably
prevent insufflation and can worsen airway obstruction. Instead, ensure a proper
seal, use a two-person technique, and ventilate at 10-12 breaths/min with a
volume of 500-600 mL.
Q7. A 72-year-old patient presents with severe pulmonary edema. BiPAP is being
considered. What is the specific parameter SNHD requires for BiPAP use that
differs from CPAP?
A) It requires a higher flow rate
B) It delivers inspiratory positive airway pressure (IPAP) and expiratory positive
airway pressure (EPAP)
C) It requires continuous capnography
D) It is contraindicated in patients over 65
Answer: B
Rationale: The fundamental difference between BiPAP and CPAP is that BiPAP
delivers two distinct pressure levels: IPAP (inspiratory) to assist with ventilation
and reduce work of breathing, and EPAP (expiratory) to maintain alveolar patency
and oxygenation. CPAP delivers a single continuous pressure throughout the
respiratory cycle. Option A is incorrect because flow rates are set based on the
