BLS Airway Management & Ventilation 2

Question 1

When performing a head-tilt chin-lift on an adult, where should you place your fingers to lift the chin?

Accepted Answer

On the bony part of the lower jaw

Answer

Fingers should be placed on the bony part of the lower jaw to lift the chin without compressing the soft tissue, which could obstruct the airway.

Question 2

A bag-mask device should deliver approximately how much air volume per breath to an adult?

Accepted Answer

400–600 mL

Answer

Each breath should deliver approximately 500–600 mL (roughly 400–600 mL range), enough to produce visible chest rise without causing gastric inflation.

Question 3

Which of the following is a sign that rescue breaths are being delivered correctly?

Accepted Answer

The patient's chest visibly rises with each breath

Answer

Visible chest rise with each breath confirms air is entering the lungs rather than the stomach.

Question 4

In an unresponsive adult patient with no suspected spinal injury, which maneuver is preferred to open the airway?

Accepted Answer

Head-tilt chin-lift

Answer

The head-tilt chin-lift is the preferred airway maneuver for unresponsive patients without suspected spinal injury.

Question 5

How long should each rescue breath be delivered during CPR?

Accepted Answer

About 1 second

Answer

Each breath should be given over about 1 second, which is enough to produce chest rise without causing excessive gastric inflation.
