  1. 1. Why is water-soluble lubricant used for inserting a nasal airway?
    • � Lubricant is needed to ease insertion.
    • � Also, water-soluble lubricant is used because petroleum gels can cause a toxic reaction when they come in contact with mucosa.
  2. 2. What complications might arise from the use of a nasopharyngeal airway?
    • � Adhesion to nasal mucosa
    • � Epistaxis (nose bleeding)
    • � Sinusitis
    • � Airway obstruction
    • � Gagging if improperly sized.
  3. 3. What complications might arise from an improperly sized oropharyngeal
    • � May gag and vomit
    • � Airway obstruction
    • � Laryngospasm
  4. 4. What complications might arise from an improperly sized nasopharyngeal airway?
    • � Airway obstruction
    • � Gagging and vomiting
    • � Septal Perforation
  5. 5. For each of the following scenarios, indicate what type of airway should be used. State your rationale.
    • a. Semiconscious patient in the room:
    • � Nasopharyngeal airway
    • b. An elderly, nonintubated patient who requires frequent suctioning
    • � Nasopharyngeal airway (or nasal trumpet if patient can maintain own airway)
    • c. A patient in cardiac arrest in the emergency room receiving basic life support (BLS)
    • � Oropharyngeal airyway until intubation can be performed
  6. 6. A patient is brought into the emergency room with an Esophageal-Tracheal Combitube (E.T.C.) in place. What is the proper sequence of actions for replacing the E.T.C.?
    • � Suction the pharynx
    • � Expose vocal cords with laryngoscope
    • � Intubate patient with endotracheal tube
    • � Insure proper placement of endotracheal tube and inflate cuff
    • � Deflate Esophageal-Tracheal Combitube cuff and remove the tube
    • � Be prepared to suction if the patient vomits
  7. 7. You are called to the recovery room to administer 40% oxygen to a patient with laryngeal airway in place. Describe the equipment setup you would employ, including all connectors and adaptors needed.
    � Large Volume Nebulizer (LVN) set at 40% FIO2, with corrugated tubing and water trap to a Briggs T-adapter. Attach to the 15mm adapter of the LMA (Laryngeal mask airway).
  8. 8. The patient in question 7 has regained consciousness and the laryngeal airway has been removed. What should you do with the device at this time?
    • � Non-disposable � Place in biohazard bag, label it, and send it to central supply for sterilization (autoclave).
    • � Disposable � just throw it in the trash.
