Practice Questions with Answers and Rationales|

Introduction
The West Coast EMT Block Exam is a comprehensive assessment tool used in
EMT training programs aligned with the National Registry of Emergency Medical
Technicians (NREMT) standards. These block exams are typically administered
throughout the course to evaluate competency across all major domains of
prehospital emergency care. The exam structure generally covers eight content
domains: Advanced Airway Management, Cardiovascular and Respiratory
Emergencies, Neurological and Endocrine Emergencies, Trauma Emergencies,
Special Populations, EMS Operations and Safety, Pharmacology, and Integrated
Scenarios.
Each question in this practice set follows the NREMT-style multiple-choice format
with four options (A-D). The correct answer is indicated along with a detailed
rationale explaining why that answer is correct and why the distractors are
incorrect. This format is designed to reinforce clinical judgment and core content
knowledge essential for both the block exam and the NREMT certification exam.
Section 1: Airway Management and Ventilation (Questions 1-30)
1. Which airway device is inserted blindly into the esophagus or pharynx to
ventilate patients when endotracheal intubation is unavailable?
A. An oropharyngeal airway
B. A supraglottic airway (e.g., King LT)
C. A nasal cannula
D. A nonrebreather mask
,Correct Answer: B
Rationale: Supraglottic airways such as the King LT or Combi tube are blind-
insertion devices used to provide ventilation when intubation is not available. An
oropharyngeal airway only maintains tongue displacement and does not provide
ventilation. Nasal cannulas and nonrebreather masks are oxygen delivery devices,
not airways.
2. Which patient is the BEST candidate for a supraglottic airway?
A. A responsive patient with an intact gag reflex
B. An apneic, unresponsive patient without a gag reflex
C. A patient who is talking
D. A patient with a complete upper airway obstruction from a foreign body
Correct Answer: B
Rationale: Supraglottic airways are used in deeply unresponsive, apneic patients
without a gag reflex. They do not bypass a complete foreign-body obstruction and
are contraindicated in patients with intact gag reflexes.
3. Which step confirms correct placement of a supraglottic airway?
A. The patient begins to cough
B. Adequate chest rise and improvement in oxygenation
C. Absence of breath sounds
D. Gastric distention
Correct Answer: B
Rationale: Correct placement is confirmed by adequate bilateral chest rise,
improved oxygenation, and breath sounds over the lungs. Coughing indicates the
patient has a gag reflex and the device may be stimulating the airway. Gastric
distention suggests esophageal placement or excessive ventilation pressure.
,4. Which advanced airway device is inserted into the esophagus and then
ventilates via a separate lumen, with gastric and pharyngeal balloons?
A. Combi tube
B. OPA
C. NPA
D. Nasal cannula
Correct Answer: A
Rationale: The Combi tube is a double-lumen, blind-insertion airway with gastric
and pharyngeal balloons that ventilates regardless of esophageal or tracheal
placement. OPAs and NPAs are basic adjuncts, not ventilatory devices.
5. Which waveform capnography finding indicates the supraglottic airway is
ventilating effectively?
A. A continuous square (rectangular) EtCO2 waveform
B. A flatline with no waveform
C. A slowly rising then falling spike with no plateau
D. No waveform at all
Correct Answer: A
Rationale: A normal nanogram shows a square waveform with a plateau, indicating
exhaled CO2 from the lungs and effective ventilation. A flatline indicates no CO2
detection (esophageal placement or cardiac arrest). A shark-fin pattern suggests
bronchospasm.
6. Which ventilation rate is recommended when ventilating an adult with a
supraglottic airway during cardiac arrest?
A. One breath every 2 seconds
B. One breath every 6 seconds (10 breaths/min)
C. One breath every 12 seconds
D. One breath every 15 seconds
, Correct Answer: B
Rationale: With an advanced airway in place during cardiac arrest, ventilations are
delivered once every 6 seconds (10/min) without pausing compressions. This rate
prevents excessive ventilation while maintaining adequate oxygenation.
7. Once an advanced airway is placed during CPR, compressions and
ventilations should be:
A. Continuous compressions with asynchronous ventilations
B. Paused compressions to deliver ventilations
C. Compressions at 100/min with ventilations every 10 seconds
D. Compressions and ventilations in a 30:2 ratio
Correct Answer: A
Rationale: Once an advanced airway is in place, compressions become continuous
and ventilations are delivered asynchronously at 10 breaths per minute. The 30:2
ratio applies only before an advanced airway is placed.
8. When ventilating an apneic adult with a bag-valve mask, you should
squeeze the bag:
A. Until it is empty
B. Over a period of 2 seconds
C. At a rate of 20 breaths/min
D. Until visible chest rise is noted
Correct Answer: D
Rationale: The goal of BVM ventilation is to achieve adequate tidal volume
without overinflating the lungs. Squeeze the bag over 1 second and observe for
visible chest rise. Ventilate adults at 10-12 breaths/min. Squeezing until the bag is
empty or over 2 seconds may cause gastric distention.
