Answer:
When preparing to insert a nasopharyngeal airway in a patient who presents with a decreased level of consciousness and snoring respirations following a motor vehicle collision, it is most important to consider the proper size of the airway to prevent further complications.
To determine the correct size of the nasopharyngeal airway, you can measure it by comparing it to the distance between the tip of the patient's nose and the angle of the jaw. The airway should be long enough to extend from the tip of the nose to the angle of the jaw. Inserting an airway that is too short may not effectively maintain an open airway, while inserting an airway that is too long can damage the nasal mucosa or cause gagging.
It is crucial to ensure the patient's head is in a neutral position before inserting the nasopharyngeal airway. Gently insert the lubricated airway into one nostril with the bevel facing the septum. Advance the airway along the floor of the nasal passage until the flange rests against the nostril. Make sure to monitor the patient for any signs of discomfort or resistance during the insertion process.
Always be prepared to remove the airway if the patient shows signs of gagging, coughing, or vomiting. Proper suctioning equipment should be readily available in case the patient needs to be cleared of any secretions or blood.
Remember that proper insertion of a nasopharyngeal airway is crucial in maintaining a patent airway in a patient with altered consciousness and compromised respiratory function.
