Batch 1: Airway, Resuscitation, & Patient Assessment (Questions
1–50)
Airway Management & Ventilation
1. A 64-year-old male with a history of COPD is in severe respiratory distress. He is alert,
anxious, and leaning forward. His oxygen saturation is 82% on room air. Which
intervention is most appropriate?
o Continuous Positive Airway Pressure (CPAP)
o CPAP is indicated for alert, cooperative patients with severe respiratory distress from
COPD or pulmonary edema who have intact airway reflexes and stable blood pressure.
,2. You are suctioning a 45-year-old unresponsive trauma patient who has copious
amounts of blood and vomit in the airway. What is the maximum duration for a single
suctioning attempt?
o 15 seconds
o To prevent severe hypoxia, never suction an adult patient's airway for longer than 15
seconds at a time, applying suction only as you withdraw the catheter.
3. While performing suctioning on a 3-year-old pediatric patient with a history of asthma,
how long should you limit your suctioning attempt?
o 10 seconds
o Pediatric patients have smaller oxygen reserves; suctioning must be limited to a
maximum of 10 seconds to avoid profound hypoxemia.
4. A newborn infant requires immediate suctioning due to a compromised airway filled with
amniotic fluid. What is the absolute maximum time allowed for this procedure?
o 5 seconds
o Infants are highly sensitive to hypoxia and vagal stimulation; suctioning must never
exceed 5 seconds.
5. You are managing a patient with a stoma who is in respiratory arrest. If you cannot seal
a pediatric pocket mask around the stoma to provide ventilations, what is the next step?
o Seal the mouth and nose and ventilate through the stoma
o If stoma ventilation fails or leaks, ensure the patient's upper airway (mouth and nose) is
sealed completely to optimize pressure delivery through the stoma.
6. Which anatomical structure represents the dividing line between the upper and lower
airways?
,o Vocal cords
o The larynx, specifically the vocal cords, serves as the definitive anatomical border
separating the upper airway from the lower respiratory tract.
7. A patient presents with snoring respirations. This sound is a definitive indication of
which airway issue?
o Partial upper airway obstruction by the tongue
o Snoring is caused by the relaxation of the hypopharyngeal muscles, allowing the tongue
to fall backward and partially block the upper airway.
8. You hear a high-pitched, whistling sound during inspiration in a 2-year-old child
presenting with croup. What is this sound called?
o Stridor
o Stridor is a harsh, high-pitched upper airway sound indicating narrowing or partial
obstruction of the larynx or trachea.
9. While auscultating the lungs of a patient experiencing a severe asthma exacerbation,
you hear musical, whistling sounds on expiration. What does this indicate?
o Bronchoconstriction
o Wheezing is caused by lower airway narrowing due to bronchospasm, mucosal edema,
or mucus plugging.
10. What is the primary chemical stimulus that drives a healthy person's respiratory rate and
depth?
o Carbon dioxide levels in the arterial blood
o The body's primary respiratory drive is controlled by central chemoreceptors that
monitor the level of carbon dioxide (\(CO_{2}\)) and pH changes in cerebrospinal fluid.
, 11. What respiratory drive is commonly utilized by patients with chronic, long-standing
COPD?
o Hypoxic drive
o Chronic retention of \(CO_{2}\) causes peripheral chemoreceptors to adapt, shifting the
primary respiratory stimulus to low levels of dissolved oxygen (\(O_{2}\)).
12. A 19-year-old male is found unresponsive after a suspected opioid overdose. His
respirations are shallow at 6 breaths per minute. What is your immediate priority?
o Begin positive-pressure ventilation via bag-valve mask
o Inadequate respiratory rate and tidal volume constitute respiratory failure, requiring
immediate assisted ventilation via BVM with high-flow oxygen.
13. You are preparing to insert an oropharyngeal airway (OPA) into an unresponsive adult
patient. How do you measure the device to ensure a proper fit?
o From the corner of the mouth to the earlobe
o An OPA is sized correctly by measuring from the corner of the patient's mouth to the tip
of the earlobe or the angle of the jaw.
14. You have inserted an OPA into a semi-conscious patient, and the patient begins to gag
and cough. What is your immediate action?
o Remove the airway immediately
o An OPA must be removed immediately if a patient has an intact gag reflex to prevent
vomiting, laryngospasm, or aspiration.
15. How should a nasopharyngeal airway (NPA) be measured before insertion?
o From the tip of the nose to the earlobe
