FREE BLS Airway Management & Ventilation Questions and Answers

Question 1

What is the most common method used to open the airway of an unresponsive victim without suspected spinal injury?

Accepted Answer

Head tilt–chin lift

Answer

The head tilt–chin lift maneuver is the primary and most common technique used to open the airway of an unresponsive victim when there is no suspected spinal injury. This method effectively moves the tongue away from the back of the throat, which is a frequent cause of airway obstruction in unconscious individuals. It creates a clear passage for breathing.

Question 2

Which device is commonly used to maintain a patent airway in an unconscious patient?

Accepted Answer

Oropharyngeal airway

Answer

An Oropharyngeal Airway (OPA) is a device commonly used in unconscious patients to maintain a patent airway by preventing the tongue from obstructing the pharynx. It is inserted into the mouth and extends to the pharynx, holding the tongue forward. OPAs are suitable for patients without a gag reflex.

Question 3

Which technique is used to provide breaths using a bag-valve-mask (BVM)?

Accepted Answer

E-C clamp technique

Answer

The E-C clamp technique is the standard method for holding a bag-valve-mask (BVM) to a patient's face while providing breaths. This technique involves using the thumb and index finger to form a 'C' shape around the mask for a tight seal, while the remaining three fingers form an 'E' shape to lift the jaw and maintain an open airway. This ensures effective ventilation and minimizes air leakage.

Question 4

How often should rescue breaths be delivered during CPR with an advanced airway?

Accepted Answer

Every 6 seconds

Answer

When an advanced airway (like an endotracheal tube or supraglottic airway) is in place during CPR, rescue breaths should be delivered asynchronously with chest compressions. The recommended rate is one breath every 6 seconds (10 breaths per minute). This allows for continuous chest compressions without interruption, optimizing blood flow while still providing adequate oxygenation.

Question 5

Which airway device can be used in a conscious or semi-conscious patient?

Accepted Answer

Nasopharyngeal airway

Answer

A Nasopharyngeal Airway (NPA) is an airway device that can be used in conscious or semi-conscious patients because it is generally better tolerated than an Oropharyngeal Airway (OPA) and does not typically trigger a gag reflex. It is inserted through the nostril into the posterior pharynx, providing an open airway path.
