Answer to Question 1

ANS: B
Because insertion of an oropharyngeal airway can provoke a gag reflex, vomiting, or laryngeal spasm, these devices generally are contraindicated for conscious or semiconscious patients. They also are contraindicated when there is trauma to the oral cavity or mandibular or maxillary areas of the skull. Moreover, these airways should never be placed when either a space-occupying le-sion or a foreign body obstructs the oral cavity or pharynx.

Answer to Question 2

ANS: D
A nasopharyngeal airway should not be used when there is trauma to the nasal region or when space-occupying lesions or foreign objects block the nasal passages. Moreover, because of the smallness of the nasal passageway in children and infants, the use of nasal airways is generally limited to adults.
