      False

    Correct Answer
    B. False
    Explanation
    When inserting a nasal airway, the bevel should be turned towards the base of the nostril or septum. This allows for easier insertion and minimizes the risk of injury to the nasal mucosa and other structures.

    Rate this question:

  • 15. 

    Do not use a nasal airway if a patient has mid-face trauma or a possible basal skull fracture. True or False

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Using a nasal airway in a patient with mid-face trauma or a possible basal skull fracture can potentially worsen the injury or cause further damage. These conditions involve damage or fractures to the bones in the middle of the face or the base of the skull, which can be delicate and easily disrupted. Inserting a nasal airway in such cases may increase the risk of complications, such as bleeding, worsening of the fracture, or damage to surrounding structures. Therefore, it is recommended to avoid using a nasal airway in patients with mid-face trauma or a possible basal skull fracture.
