To open the airway using the jaw-thrust you position yourself at
The top of the patient's head. (Limmer & O'keefe pg 182)
The best way to clear a patient's airway from vomitus, secretions or blood
A wide bore, rigid yankauer suction device. (Limmer & O'keefe pg 183)
The most common impediment to an open airway is
A lack of airway muscle tone. (Limmer & O'keefe pg 183)
A curved device inserted through the patient's mouth into the pharynx to help maintain an open airway
Oropharyngeal airway (OPA). (Limmer & O'keefe pg 183)

BSI recommended when working with the airway
Gloves, goggles and mask. (Limmer & O'keefe pg 184)
You should measure an oropharyngeal airway from ---to---
The corner of the mouth to the tip of the earlobe. (Limmer & O'keefe pg 184)
Another way to measure an OPA
From the center of the patient's mouth to the angle of the jaw. (Limmer & O'keefe pg 184)
To insert an OPA position the airway device so that its tip is pointing toward---
The roof of the patient's mouth. (Limmer & O'keefe pg 185)
Using a tongue depressor you should insert an OPA with the tip pointing - preferred for infant and child
Facing down and forward. (Limmer & O'keefe pg 186)
Type of airway adjunct you should use for patient who has intact gag reflex. Or teeth are clenched or oral injuries are present
Nasopharyngeal airway. (Limmer & O'keefe pg 186)
You should measure the nasopharyngeal airway form
Patient's nostril to the tip of the earlobe or to the angle of the jaw. (Limmer & O'keefe pg 187)
Lubricate the outside of the NPA with
Water-based lubricant. (Limmer & O'keefe pg 187)
When inserting an NPA the bevel should point towards

Contraindication for the use of an NPA is
Skull fracture indicated by CSF coming from nose or ears. (Limmer & O'keefe pg 188)
The method of using a vacuum device to remove materials form mouth. Whenever gurgling sound is heard you must...
Suctioning. (Limmer & O'keefe pg 188)
To be effective, suction devices must furnish an air intake of at least
30 liters per minute the system must generate a vacuum of no less than 300 mmHg. (Limmer & O'keefe pg 189)
The most popular type of suction tip is
The rigid pharyngeal tip "Yankauer,". (Limmer & O'keefe pg 190)
Touching the back of the throat while suctioning may cause
Gag reflex or activation of vagus nerve which can slow the heart rate. (Limmer & O'keefe pg 190)
To clear the suction tube you should have available
A container of water. (Limmer & O'keefe pg 191)
When copious thick secretions or vomit is present consider
Removing the rigid tip or catheter and use the large bore tubing. (Limmer & O'keefe pg 190)
You should try limiting suctioning for no longer than
10 seconds. (Limmer & O'keefe pg 190)
Prolonged suctioning can cause
Hypoxia. (Limmer & O'keefe pg 190)
If patient continues vomiting
Continue suctioning longer than 10 seconds. (Limmer & O'keefe pg 190)
before suctioning through an endotracheal tube you should
Pre-oxygenate patient. (Limmer & O'keefe pg 190)
You should suction in the way in or out
In the way out. (Limmer & O'keefe pg 192)
When suctioning with a suction catheter you should measure the catheter from
Corner of the mouth to the earlobe. (Limmer & O'keefe pg 192)
Suctioning is best delivered with the patient turned on his....
Turned on his side. (Limmer & O'keefe pg 192)
Remove visible solid objects from mouth using
