A 30-year-old male is admitted to the emergency room after a severe motor vehicle accident. Assessment reveals he had a full stomach with significant reflux. His effective static compliance is measured at 20 mL/cm H2O.
 
  Which of the following types of airways would be appropriate to provide ventilatory support for this patient?
  a. Nasopharyngeal airway c. Endotracheal tube
  b. Laryngeal mask airway d. Endobronchial tube

Question 2

Which of the following statements is true?
 
  a. Water that exists in the form of individual molecules in a gaseous state is humidity.
  b. Water that exists in the form of individual molecules is an aerosol.
  c. Water that exists in the form of particulate matter is relative humidity (RH).
  d. Water that exerts no pressure is a vapor.

Answer to Question 1

ANS: C
A laryngeal mask airway is contraindicated for three reasons; there was evidence he had a full stomach, there was evidence of gastroesophageal reflux, and his lung compliance is decreased. This would require an endotracheal tube to support ventilation. There is no evidence that a dou-ble lumen endotracheal tube is necessary.

Answer to Question 2

ANS: A
Humidity is water that exists in the form of individual molecules in the vaporous or gaseous state. An aerosol is a suspension of solid or liquid particles in a gas. Water vapor does exert pres-sure, although the pressure may vary.
