EMT Airway Questions & Answers 2026 | High-Yield Review |
Graded A+
1. Describe the significance of vital capacity in assessing respiratory health.
Vital capacity is irrelevant in assessing respiratory health, as it only
measures air pressure.
Vital capacity is the amount of air inhaled during normal breathing,
which helps in assessing oxygen intake.
Vital capacity measures the total lung volume at rest, which is crucial
for diagnosing lung diseases.
Vital capacity is significant as it indicates the maximum amount of air
a person can expel, reflecting lung function and respiratory health.
2. Describe why the head-tilt-chin lift maneuver is contraindicated for trauma
patients.
It may exacerbate spinal injuries.
It requires additional equipment.
It is only for pediatric patients.
It is ineffective in trauma cases.
3. Describe the relationship between hyperventilation and carbon dioxide
levels in the blood.
Hyperventilation leads to shallow breathing, increasing carbon
dioxide levels.
Hyperventilation has no impact on carbon dioxide levels.
Hyperventilation only affects oxygen levels in the blood.
, Hyperventilation causes rapid or deep breathing, which results in
decreased carbon dioxide levels in the blood.
4. In a scenario where a patient is experiencing an obstructed airway, which
anatomical structures should be assessed to determine the cause of the
obstruction?
The hard and soft palates, cheeks, and tongue.
The diaphragm and abdominal muscles.
The nasal cavity and sinuses.
The lungs and bronchi.
5. Anaphylaxis is a potentially life-threatening allergic reaction that can occur:
Within seconds
Within minutes
Can be delayed for hours
All of the above
6. What condition occurs when air fills the stomach during artificial ventilation?
Gastric distention
Pneumothorax
Bronchospasm
Aspiration
7. Respiration is the exchange of
water and salt
hydrogen and carbon dioxide
, nitrogen and oxygen
oxygen and carbon dioxide
8. An allergen is:
A molecule that evokes the production of one or more antibodies
A substance that causes a hypersensitive reaction
A protein produced and stimulated by a specific antigen to neutralize
a specific allergen.
9. Describe how the symptoms of asthma affect a patient's ability to breathe.
Asthma causes the lungs to expand excessively, leading to
hyperventilation.
The symptoms of asthma, such as airway spasms and excessive
mucus, obstruct airflow, making it difficult for the patient to breathe.
The symptoms of asthma primarily affect the heart, not the respiratory
system.
Asthma symptoms enhance airflow, allowing for easier breathing.
10. When is a jaw-thrust maneuver appropriate for use to open an airway?
a conscious trauma patient who has no motor or sensation below the
nipple line.
a conscious trauma patient with penetrating cervical spinal injury
for an unconscious person who is snoring
for an unconscious patient with suspected cervical spinal trauma
11. What is the result of a complete airway obstruction?
, Inability to breathe, talk, or cough
Decreased oxygen saturation
Cyanosis of the skin
Increased respiratory rate
12. Asthma is characterized by which of the following in physical features?
Chronic inflammation
Airway hyperresponsiveness
airway swelling
mucus production
all of the above
13. Which of the following answer choices correctly describes the role of
surfactant in the lungs?
It moistens air as it enters the lungs.
It causes water to form beads within the lungs.
It increases the surface tension of water.
It reduces the chance that the alveoli walls will stick together and
collapse.
14. In a scenario where a patient presents with labored breathing and cyanosis,
what immediate action should an EMT take?
Encourage the patient to walk
Perform a physical examination
Provide fluids
