The maximum laryngeal mask airway cuff pressure is ____ cm H2O.

(Answer to Q. 1)  ANS: D
The laryngeal mask airway is designed to form a low-pressure seal in the laryngeal inlet by means of an inflated cuff. The cuff pressures should not exceed 60 cm H2O.

(Answer to Q. 2)  ANS: C
The laryngeal mask airway is of particular benefit in patients with a known or anticipated diffi-cult airway.

(Answer to Q. 3)  ANS: C
Insertion of a nasal airway when there is a basilar skull fracture does increase the risk of pene-trating the brain with the nasal airway, but it is not a long-term complication. Nasal bleeding is a complication of the insertion of the airway. Hypoxia is a risk factor when an airway is not able to be established or is compromised. A nasal airway can introduce organisms into the nasal cavity and the sinuses; therefore, when long-term nasal tube use is required, the risk to the patient in-creases.

(Answer to Q. 4)  ANS: D
The size of the laryngeal mask airway is based on the patient's weight and may not be easy to choose. The placement of a laryngeal mask airway must be checked by using measurements of end-tidal carbon dioxide (CO2) and breath sounds. Laryngeal mask airways do not protect the lungs from aspiration because they are noninvasive. Laryngeal mask airways are useful in emer-gencies because they do not require airway manipulation or extreme head positioning, which minimizes flexion and extension of the cervical spine for proper placement.

(Answer to Q. 5)  ANS: A
The laryngeal mask airway is the only airway that has a cuff that rests in the posterior pharynx, with its tip on the upper esophageal sphincter.

(Answer to Q. 6)  ANS: D
A tongue blade can be used during the insertion of an oropharyngeal airway to move the tongue to one side. Intermittent pressure might cause damage and bleeding to the inside of the nasal cavity. An Endotrol tube is an endotracheal tube that allows for the manipulation of the tip of the tube. It does not facilitate insertion of a nasal airway.
