LATEST UPDATE 2026/2027 | GRADED A+
This comprehensive test bank contains 250 expert-verified practice questions with short
rationales, specifically designed for the West Coast EMT Block 2 Exam. It covers all key
content areas including airway management, respiratory emergencies, cardiac emergencies,
medical emergencies, trauma care, patient assessment, pharmacology, and EMS operations. All
questions reflect currently tested concepts and frequently assessed scenarios based on the
latest National EMS Education Standards. Each question includes the verified correct answer
and a concise rationale to reinforce understanding of critical EMT concepts essential for exam
success and clinical practice.
SECTION 1: AIRWAY MANAGEMENT & RESPIRATORY (Questions 1-50)
1. The EMT should assess a patient's tidal volume by?
A. observing for adequate chest rise
B. assessing the facial area for cyanosis
C. counting the patient's respiratory rate
D. measuring the patient's oxygen saturation
Correct Answer: A. Observing for adequate chest rise
Rationale: Tidal volume is the volume of air moved in or out of lungs by a single breath,
observed by adequate chest rise. If rise is shallow, tidal volume is likely reduced.
2. In an otherwise healthy individual, the primary stimulus to breathe is a(n):
A. increased level of oxygen in the blood
B. decreased level of oxygen in the blood
C. increased level of carbon dioxide in blood
D. decreased level of carbon dioxide in blood
Correct Answer: C. increased level of carbon dioxide in blood
,Rationale: Under control of the brain stem, rising levels of carbon dioxide in the arterial
blood normally stimulate breathing in an otherwise healthy patient.
3. Signs of adequate breathing in the adult include all of the following, EXCEPT:
A. pink, warm, dry skin
B. shallow chest rise
C. symmetrical chest movement
D. a respiratory rate of 16 breaths/min
Correct Answer: B. shallow chest rise
Rationale: Shallow chest rise indicates reduced tidal volume and inadequate breathing.
Pink, warm, dry skin, symmetrical chest movement, and normal rate indicate adequate
breathing.
4. During insertion of an oropharyngeal airway into an unconscious patient, she begins to
vomit. The first thing you should do is:
A. turn the patient on her side
B. remove the airway at once
C. suction the patient's mouth
D. use a smaller-sized oral airway
Correct Answer: A. turn the patient on their side
Rationale: Turning the patient on their side allows vomit to drain and prevents aspiration.
Suctioning can be done after positioning.
5. In which of the following patients would a nasopharyngeal airway be contraindicated?
A. a semiconscious patient with a gag reflex
B. an unconscious patient with an intact gag reflex
C. a patient who fell 20 feet and landed on their head
D. an unconscious patient who gags when you insert an oral airway
Correct Answer: C. a patient who fell 20 feet and landed on their head
Rationale: Nasopharyngeal airways are contraindicated in patients with severe head or
facial injuries due to the risk of inserting into the cranial vault through a basilar skull
fracture.
6. You are delivering oxygen to a patient with a nasal cannula at 4 L/min when he begins
to complain of a burning sensation in his nose. You should:
A. remove the nasal cannula
B. apply a nonrebreathing mask
C. attach an oxygen humidifier
D. increase the flow rate to 6 L/min
,Correct Answer: C. attach an oxygen humidifier
Rationale: Administering "dry" oxygen, especially over a prolonged period, can result in
drying of nasal membranes. A humidifier adds moisture to the oxygen.
7. A patient is found unconscious after falling from a third floor window. His respirations
are slow and irregular. You should:
A. place him in the recovery position
B. apply oxygen via a nonrebreathing mask
C. suction his airway for up to 15 seconds
D. assist his breathing with a bag-valve mask device
Correct Answer: D. assist his breathing with a bag-valve mask device
Rationale: Slow and irregular respirations indicate inadequate ventilation, requiring
assisted ventilation with a bag-valve mask device.
8. When ventilating an apneic adult with a simple barrier device, 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. until visible chest rise is noted
Rationale: Visible chest rise indicates adequate tidal volume. Squeezing the bag until
empty can cause gastric distention and lung injury.
9. You and your partner are ventilating an apneic adult when you notice that his stomach
is becoming distended. You should:
A. suction his airway for up to 15 seconds
B. reposition his head
C. increase the rate and volume
D. decrease ventilation rate but increase the volume
Correct Answer: B. reposition his head
Rationale: Gastric distention occurs when air enters the stomach due to improper head
positioning or excessive ventilation pressure. Repositioning the head helps open the
airway.
, 10. You are managing a 62-year-old who complains of crushing chest pain. Her BP is
84/64 with HR of 110. Medical control advises you to assist in her taking her prescribed
nitroglycerin. You should:
A. reassess the HR then assist with nitro
B. repeat the BP to DR and confirm order
C. wait 10 mins, reassess BP, then give nitro
D. administer the nitro and reassess BP
Correct Answer: B. Repeat the BP to DR and confirm order
Rationale: Nitroglycerin is a vasodilator that lowers BP and is contraindicated with systolic
BP <100 mmHg. Confirm the order with the physician due to the low BP.
11. Activated charcoal is indicated for patients who ingested certain drugs/toxins because
it:
A. binds to the poison in the stomach
B. neutralizes the poison chemically
C. induces vomiting to remove poison
D. accelerates poison absorption
Correct Answer: A. binds to the poison in the stomach
Rationale: Activated charcoal binds to certain poisons in the gastrointestinal tract,
preventing their absorption into the bloodstream.
12. What is the normal respiratory rate for an adult?
A. 8-12 breaths/min
B. 12-20 breaths/min
C. 20-28 breaths/min
D. 28-36 breaths/min
Correct Answer: B. 12-20 breaths/min
Rationale: The normal adult respiratory rate is 12-20 breaths per minute at rest.
13. What is the correct suction time for an adult?
A. 5 seconds
B. 10 seconds
C. 15 seconds
D. 20 seconds
Correct Answer: C. 15 seconds
Rationale: Suctioning should be limited to 15 seconds for adults to avoid hypoxia.
Pediatric suctioning is limited to 10 seconds.
