QUESTIONS & 100% VERIFIED ANSWERS STUDY GUIDE UPDATED 2026
VERIFIED QUESTIONS WITH DETAILED RATIONALES
Question 1: Which of the following is the preferred method for opening the
airway of a trauma patient with a suspected cervical spine injury?
A. Head-tilt/chin-lift maneuver
B. Modified jaw-thrust maneuver
C. Nasopharyngeal airway insertion
D. Oropharyngeal airway insertion
CORRECT ANSWER: B. Modified jaw-thrust maneuver
RATIONALE: The modified jaw-thrust maneuver is the preferred technique for
opening the airway in trauma patients with suspected cervical spine injury
because it minimizes movement of the cervical spine while effectively lifting the
tongue away from the posterior pharynx. The head-tilt/chin-lift maneuver may
exacerbate spinal injury and should be avoided until cervical spine injury is ruled
out.
Question 2: An adult patient presents with severe respiratory distress, audible
stridor, and difficulty speaking. Which intervention should the EMT perform
FIRST?
A. Administer high-flow oxygen via non-rebreather mask
B. Prepare for immediate transport to a trauma center
C. Assess the patient's ability to cough effectively
D. Suction the oropharynx to clear secretions
CORRECT ANSWER: C. Assess the patient's ability to cough effectively
RATIONALE: Stridor indicates upper airway obstruction. Before intervening, the
EMT must assess whether the patient can cough, speak, or breathe, as this
,determines if the obstruction is partial or complete. If the patient can cough
effectively, encouraging coughing is preferred; if not, immediate airway
maneuvers or suctioning may be required. Assessment guides appropriate
intervention.
Question 3: Which sign is MOST indicative of adequate ventilation in an adult
patient receiving bag-valve-mask assistance?
A. Chest rise with each ventilation
B. Oxygen saturation above 94%
C. Heart rate returning to normal range
D. Absence of cyanosis
CORRECT ANSWER: A. Chest rise with each ventilation
RATIONALE: Visible chest rise with each bag-valve-mask ventilation is the most
immediate and reliable indicator that air is entering the lungs and ventilation is
adequate. While oxygen saturation, heart rate, and skin color are important
assessment parameters, they are secondary indicators and may lag behind actual
ventilation effectiveness.
Question 4: A patient with a history of COPD is experiencing an acute
exacerbation. Which oxygen delivery method is MOST appropriate for initial
management?
A. Non-rebreather mask at 15 L/min
B. Nasal cannula at 2-4 L/min
C. Bag-valve-mask with 100% oxygen
D. Venturi mask set at 24% FiO2
CORRECT ANSWER: B. Nasal cannula at 2-4 L/min
RATIONALE: Patients with COPD may have hypoxic drive, where their respiratory
stimulus depends on low oxygen levels rather than elevated CO2. High-flow
oxygen can suppress this drive and worsen hypercapnia. Starting with low-flow
,oxygen via nasal cannula allows titration to maintain SpO2 between 88-92%,
balancing oxygenation with respiratory drive preservation.
Question 5: During suctioning of an adult patient's oropharynx, what is the
MAXIMUM recommended duration for a single suction pass?
A. 5 seconds
B. 10 seconds
C. 15 seconds
D. 20 seconds
CORRECT ANSWER: B. 10 seconds
RATIONALE: Suctioning should not exceed 10 seconds in adults to minimize the
risk of hypoxia, bradycardia, and mucosal trauma. Prolonged suctioning removes
oxygen from the airway and can precipitate cardiac dysrhythmias. Pre-oxygenation
before suctioning and limiting duration are critical safety measures.
Question 6: Which anatomical structure is MOST commonly obstructed by the
tongue in an unconscious supine patient?
A. Larynx
B. Pharynx
C. Trachea
D. Bronchi
CORRECT ANSWER: B. Pharynx
RATIONALE: In an unconscious supine patient, loss of muscle tone allows the
tongue to fall posteriorly and obstruct the pharynx, the passage connecting the
oral cavity to the larynx. This is why airway maneuvers like jaw-thrust or head-
tilt/chin-lift are designed to lift the tongue away from the posterior pharyngeal
wall.
, Question 7: A patient is choking and cannot speak, cough, or breathe. What is
the NEXT appropriate action for the EMT?
A. Perform blind finger sweep
B. Administer abdominal thrusts
C. Apply oxygen via non-rebreather mask
D. Begin chest compressions
CORRECT ANSWER: B. Administer abdominal thrusts
RATIONALE: In a conscious patient with complete airway obstruction who cannot
speak, cough, or breathe, abdominal thrusts (Heimlich maneuver) are indicated to
generate artificial cough and expel the foreign body. Blind finger sweeps are
contraindicated as they may push the object deeper. Chest compressions are
reserved for unconscious patients.
Question 8: Which finding suggests that a nasopharyngeal airway is
appropriately sized for an adult patient?
A. The flange rests against the nostril with the tip reaching the angle of the jaw
B. The device extends from the tip of the nose to the earlobe
C. The tube length equals the distance from the nose to the xiphoid process
D. The flange sits 1 cm inside the naris with the tip at the oropharynx
CORRECT ANSWER: B. The device extends from the tip of the nose to the earlobe
RATIONALE: Proper sizing of a nasopharyngeal airway is determined by measuring
from the tip of the patient's nose to the tragus of the ear. This ensures the device
reaches the posterior pharynx without entering the larynx or causing trauma.
Incorrect sizing can lead to ineffective airway management or injury.
Question 9: What is the PRIMARY purpose of using a pocket mask with a one-
way valve during rescue breathing?
A. To increase tidal volume delivery
B. To protect the rescuer from body fluid exposure
