AIR METHODS CRITICAL CARE EXAM ACTUAL EXAM
QUESTIONS AND CORRECT DETAILED ANSWERS WITH
RATIONALES (VERIFIED ANSWERS)
Question 1
What is the most reliable method of confirming and continuously monitoring the correct
placement of an endotracheal (ET) tube?
A) Auscultation of bilateral breath sounds.
B) Direct visualization of the tube passing through the vocal cords.
C) Chest X-ray.
D) Continuous waveform capnography.
E) Absence of gastric sounds.
Correct Answer: D) Continuous waveform capnography.
Rationale: Continuous waveform capnography provides real-time confirmation of
exhaled carbon dioxide, which is present with tracheal intubation and absent with
esophageal intubation, making it the most reliable method for both confirmation
and ongoing monitoring of ET tube placement.
Question 2
The upper airway primarily consists of which of the following structures?
A) Trachea, bronchi, and bronchioles.
B) Lungs, alveoli, and diaphragm.
C) Nose, Mouth, Jaw, Oral Cavity, Pharynx, and Larynx.
D) Esophagus, stomach, and vocal cords.
E) Primary and secondary bronchi.
, Correct Answer: C) Nose, Mouth, Jaw, Oral Cavity, Pharynx, and Larynx.
Rationale: The upper airway encompasses all structures from the nose and mouth
down to the larynx, serving to warm, filter, and humidify inspired air before it
reaches the lower respiratory tract.
Question 3
Where does anatomical dead space occur, and what is its approximate volume per kilogram of
inspired tidal volume?
A) Alveoli; 5 mL/kg.
B) Trachea to terminal bronchioles; 2 mL/kg.
C) Respiratory bronchioles; 3 mL/kg.
D) Pharynx to larynx; 1 mL/kg.
E) Main bronchi; 4 mL/kg.
Correct Answer: B) Nose to terminal bronchioles, anatomical dead space. (2ml/kg of
inspired tidal volume).
Rationale: Anatomical dead space is the portion of the respiratory system where no
gas exchange takes place. This volume is approximately 2 mL per kilogram of
inspired tidal volume, conducting airflow to the gas exchange units.
Question 4
The cricothyroid membrane is an avascular structure located between the thyroid and cricoid
cartilages. It is a critical anatomical landmark for what emergency airway procedure?
A) Orotracheal intubation.
B) Nasotracheal intubation.
