Questions and Answers Covering Airway,

Introduction

The Air Methods Critical Care Exam is a rigorous, high-stakes assessment designed for flight
paramedics, critical care nurses, and transport clinicians seeking employment or annual
recertification within Air Methods—the largest air medical transport provider in the world. This
examination tests mastery across nine core domains: advanced airway management, mechanical
ventilation, hemodynamic monitoring and vasoactive titration, flight physiology and gas laws,
neurological emergencies and ICP management, trauma resuscitation, obstetric and neonatal
critical care, toxicology and pharmacology, and flight safety/operational regulations.

This 200-question practice examination has been carefully curated and updated for the 2026 exam
cycle. Each question includes the bolded correct answer followed by a detailed clinical
rationale that explains the underlying pathophysiology, evidence base, or operational reasoning.
The question bank reflects the actual content weighting, complexity, and scenario-based format of
the Air Methods Critical Care Exam, as well as aligned standards for IBSC FP-C® and CCP-C®
certifications. Use this guide to identify knowledge gaps, reinforce high-yield concepts, and build
the clinical confidence needed for a successful first-pass attempt.

,Domain 1: Airway Management and Respiratory Emergencies (Questions 1–30)

1. What is the most reliable method of confirming and monitoring correct placement of an
endotracheal tube?

 A) Auscultation of bilateral breath sounds

 B) Chest X-ray

 C) Continuous waveform capnography

 D) Pulse oximetry

Rationale: Continuous waveform capnography is the gold standard for confirming ET tube
placement, providing immediate, real-time feedback on tube dislodgement or obstruction. It
measures end-tidal CO₂ (EtCO₂), which reliably indicates pulmonary gas exchange. Colorimetric
devices and auscultation are not reliable for continuous monitoring, and chest X-ray confirms
position but provides no real-time information.

2. No gas exchange occurs from the nose to the terminal bronchioles. This area is called:

 A) Alveolar dead space

 B) Physiological dead space

 C) Anatomical dead space

 D) Shunt space

Rationale: Anatomical dead space is approximately 2 mL/kg of ideal body weight. These airways
conduct airflow toward the alveoli but contain no alveoli themselves, so no gas exchange occurs
here. Physiological dead space includes anatomical dead space plus alveolar dead space.

3. The cricothyroid membrane is located between which structures?

 A) Thyroid and cricoid cartilage

 B) Cricoid and tracheal cartilage

 C) Hyoid and thyroid cartilage

,  D) Arytenoid and cricoid cartilage

Rationale: The cricothyroid membrane is an avascular structure that connects the thyroid and
cricoid cartilages. It is the preferred site for emergency cricothyrotomy—a lifesaving procedure
used when endotracheal intubation is impossible.

4. The upper airway consists of which structures?

 A) Trachea, bronchi, bronchioles

 B) Nose, mouth, jaw, oral cavity, pharynx, and larynx

 C) Alveoli and alveolar sacs

 D) Epiglottis only

Rationale: The upper airway extends from the nares to the larynx. These structures warm, humidify,
and filter air before it reaches the lower airway. Knowing upper airway anatomy is critical for
managing airway obstruction and performing proper intubation.

5. A PaCO₂ greater than 45 mmHg indicates:

 A) Metabolic acidosis

 B) Metabolic alkalosis

 C) Respiratory acidosis

 D) Respiratory alkalosis

Rationale: Normal PaCO₂ range is 35–45 mmHg. A value above 45 indicates hypoventilation and
respiratory acidosis, commonly caused by COPD exacerbation, opioid overdose, or neuromuscular
weakness. PaCO₂ is inversely related to alveolar ventilation—decreased ventilation drives PaCO₂
upward.

6. A patient with COPD is being transported on mechanical ventilation. Ventilator settings are SIMV,
rate 12, tidal volume 350 mL, FiO₂ 0.4, PEEP 5 cm H₂O. Plateau pressure is 30 cm H₂O. What is the
most appropriate intervention?

 A) Increase PEEP to 10 cm H₂O

,  B) Decrease tidal volume to 300 mL

 C) Increase tidal volume to 500 mL

 D) Switch to pressure control ventilation

Rationale: Plateau pressure should be kept below 30 cm H₂O to prevent ventilator-induced lung
injury. Decreasing tidal volume reduces plateau pressure. Increasing PEEP may worsen
hyperinflation in COPD patients, and increasing tidal volume worsens barotrauma.

7. Which parameter is the best indicator of adequate oxygen delivery in a critically ill patient?

 A) PaO₂

 B) SpO₂

 C) Mixed venous oxygen saturation (SvO₂)

 D) Hemoglobin concentration

Rationale: SvO₂ (or ScvO₂) reflects the balance between oxygen delivery and oxygen consumption.
A low SvO₂ indicates inadequate oxygen delivery relative to demand. PaO₂ measures oxygen
dissolved in blood—not delivery. SpO₂ is influenced by many factors, and hemoglobin is only one
component of delivery.

8. What is the gold standard for confirming intubation placement?

 A) ECO₂ waveform

 B) Breath sounds auscultation

 C) Fogging in the ET tube

 D) Pulse oximetry

Rationale: End-tidal CO₂ waveform is the gold standard for confirming intubation placement. It
provides immediate confirmation of tracheal placement and continuous monitoring of tube patency.

9. A patient has a plateau pressure of 35 cm H₂O. What is the primary concern?

 A) Underinflation of the lungs
