Aconcrete finisher has been hit in the head by a steel girder that was being placed by a crane. the man is unconscious and has a large scalp laceration on the left side of his head, starting just above his ear. the best way to ensure that the worker has an adequate airway is to: a) give oxygen via a nasal cannula. b) use a head tilt-chin lift maneuver. c) place the patient in a head-down position. d) use the jaw-thrust maneuver.

D). Use the jaw-thrust maneuver.

Explanation:

Facial trauma involves like laceration may obstruct the air passage and may restrict the breathing and ventilation. Thus an air way passage should be created so as to make patient breath and survive.

In jaw thrust maneuver the index as well as the middle fingers push the posterior aspects of the jaw upwards and the thumb makes the chin down. This is done to open the mouth. The mandible is also moved forward and tongue is pulled forward this ensures the passage of air inside the trachea.

This method will ensure adequate air supply to the concrete finisher.
