COPR Airway Management and Respiratory Emergencies 2

Question 1

Which laryngoscope blade is most appropriate for a patient with a suspected anterior (anterior larynx) and with an omega-shaped epiglottis?

Accepted Answer

Miller (straight) blade

Answer

Macintosh (curved) blade

Answer

McCoy blade

Answer

Wis-Hipple blade

Question 2

You are ventilating a patient with a BVM and notice gastric distension developing. What is the BEST intervention to reduce aspiration risk while continuing ventilation?

Accepted Answer

Apply cricoid pressure (Sellick maneuver)

Answer

Increase ventilation rate to prevent hypoventilation

Answer

Switch to mouth-to-mask ventilation

Answer

Insert a gastric tube immediately

Question 3

A patient with suspected anaphylaxis presents with stridor, hoarse voice, and rapidly developing angioedema. What airway management approach is MOST appropriate?

Accepted Answer

Perform rapid sequence intubation (RSI) early before the airway completely obstructs

Answer

Administer high-flow oxygen and wait for epinephrine to take effect before intubation

Answer

Apply a supraglottic airway as a definitive airway

Answer

Perform immediate cricothyrotomy as the first airway intervention

Question 4

Which of the following is the MOST appropriate initial approach to managing a pediatric patient with croup (laryngotracheobronchitis) exhibiting moderate respiratory distress?

Accepted Answer

Nebulized epinephrine and corticosteroids

Answer

Immediate oral endotracheal intubation

Answer

Assisted ventilation with BVM

Answer

Needle cricothyrotomy

Question 5

During RSI, succinylcholine is contraindicated in which of the following clinical situations?

Accepted Answer

Patient with a history of malignant hyperthermia or crush injury

Answer

Open globe eye injury within the last 24 hours

Answer

Patient in cardiac arrest requiring intubation

Answer

Patient with known difficult airway

Question 6

A patient presents with sudden onset pleuritic chest pain and dyspnea after a long flight. SpO2 is 91%, heart rate 118, respiratory rate 24. Lung sounds are clear bilaterally. What is the MOST likely diagnosis?

Accepted Answer

Pulmonary embolism

Answer

Spontaneous pneumothorax

Answer

Acute coronary syndrome

Answer

Pleural effusion

Question 7

What is the MOST important consideration when using a King LT (supraglottic airway) as a rescue airway device?

Accepted Answer

It does not protect against aspiration in a patient with a full stomach

Answer

It should be inflated with the maximum volume listed on the device

Answer

It provides better ventilation than endotracheal intubation

Answer

It should only be used in cardiac arrest patients
