When sizing an OPA for insertion in a 48 year old male, which sizing technique is most appropriate?
A. You should measure the OPA from the tip of the nose to the angle of the jaw.
B. You should measure the OPA from the center of the teeth to the angle of the jaw.
C. The OPA should fit between the corner of the mouth and the angle of the jaw.
D. The OPA should be large enough that the lips do not seal shut when it is properly inserted.
B. You should measure the OPA from the center of the teeth to the angle of the jaw
During your initial airway management, your patient needs suctioning for prolonged vomiting. How long should you provide this oral suctioning?
A. For 5 to 10 seconds
B. No greater then 10 seconds
C. Less then 25 seconds initially
D. For as long as needed to remove vomitus

The mechanical process of respiration (i.e. ventilation) occurs in two phases. Which phase sees a negative pressure inside the thorax to make the ventilation process work?
A. Inhalation
B. Exhalation
C. Pause before inhalation
D. Pause before exhalation
A. Inhalation

B. Immobilize the patient
C. Provide positive pressure ventilation
D. Administer high flow oxygen at 15 lpm
